2024 REVIEWS : Best Portable Power Station for CPAP / Top Picks

Case in point: The above image displays one of the most advanced power stations you can buy — the Anker 757 Powerhouse has every feature you could ever want, but it’s not cheap. This will be our reference point for the rest of this guide as it’s one of the best portable power stations for running your CPAP safely, and it has enough power to keep it running for 24.5 hours. 2024 is a very good year for buying an indoor generator. The quality options are bountiful and the prices have been dropping.

The Anker 757 is not for everyone, but it’s a good choice for anyone who needs to run their CPAP and also wants backup power for emergencies. It has several unique features, including its integrated UPS technology (uninterruptible power supply), which means when the power goes out it takes less than 20ms for the power station to switch on and begin powering your 757 Powerhouse. It has 1500W of running power so you can use it for a lot more than your CPAP. In fact, it can keep your fridge running for hours during a power outage.

Since I don’t know you I made it a priority to include a diverse list of battery power stations, like this traditional powerbank from MAXOAK. This might appeal to some people, but it also has a lot of limitations compared to a power station.

Designed Specifically for CPAP/Bi-PAP

MAXOAK K5 Powerbank / Lightweight makes it good for travelling

This model from MAXOAK is basically a big battery in a sleek case. It resembles a medical device, and designed to be extra-portable, making it a good choice for travel. It has not been approved by TSA.

It’s compatible with the majority of popular CPAP machines, including:

At 4 lbs. anybody can carry this around. Many portable power stations are under 10 lbs. and the reality is, choosing the right power station is determined by how you plan to use it. If you want to take it camping then you probably want one with fast solar charging. Or if you plan to keep your CPAP battery backup at home then you might want one with more power and the weight becomes irrelevant because you won’t be moving it from beside your bed.

The MAXOAK is a popular option as can be seen by the plentiful number of reviews for the K5. It includes more cables than you will ever need. I’m not sure why they couldn’t just allow people to select the cable they needed and have them only ship out the appropriate cable. Here’s a list of what you get:

• 1* Portable Power Bank(297Wh), 1* AC Adapter Charger(25.2V/3A), 1*DC to Airsense/Aircurve 10 Cable, 1* DC to Dreamstation Cable, 1* DC to S9 Cable, 1 *Philip System one /HDM Z1 Cable(100cm), 1* DC Connector for Transcend Mini, 1*User Manual, 1*Message Card.

Be Ready for the Worst Case Scenario

What’s the Best Portable Power Station for a CPAP? If you’re using a CPAP machine at night the last thing you want to worry about is having the power go in the middle of the night — or if you go on a camping trip or you spend a lot of time on the road in your RV then having a dependable portable power station for your CPAP is absolutely essential — not optional.

I discuss and review, in detail, the three top brands for these indoor generators, also known as power stations. Call them what you will; I personally feel that everyone should have one int their home, apartment or condo. The reality is, the power grid has become less reliable in recent years and power outages are increasing in frequency, depending on where you live. For some people a power outage is a nuisance but for those who rely on medical devices for their health, a power outage can cause real problems if they’re not prepared. Don’t be the person who puts off doing what they need to. The time is now.

Best Light-Duty Power Stations for your CPAP

Jackery Explorer 300 vs Bluetti EB34

Here are two excellent power stations from leading brands. Both are relatively affordable and will easily power you CPAP. The Bluetti is a new model and comes with great features for the price. Jackery is one of the biggest brands, they’re currently in the process of updating their power stations with their newest technology. So far they’ve updated their 2000W model and their 1000W (1000 Explorer Pro) model was released in mid-September 2022.

NOTE: Our indepth reviews of the Jackery Explorer series, and other models, can be read later in the article.

In addition, don’t buy the cheapest model. First, you need a power station that is reliable and safe to use. Second, you need to make sure it has enough power to keep your CPAP running for at least a full night of rest. I recommend buying as much power as you can afford, within reason. Third, make sure you understand what features are available to you and then be selective about the model you actually buy. And lastly, buy the best power station for your CPAP that you can afford.

We live in interesting times, no one can deny this. While some may see only doom and gloom, the more optimistic among us will recognize the great and amazing strides we’re making toward a better, cleaner, and more efficient world.

Portable battery power stations are an excellent example of the incredible technological developments that exemplify the shift in thinking that is changing the world, albeit in a very small way. Portable power is a fast growing market because of our heavy reliance on energy. Without the internet or our phones, we are completely lost — and now add in your reliance on your CPAP to be a able to sleep at night, and all of a sudden a battery power station becomes an essential item that you need.

Let’s look at more great options for you.

ECOFLOW River Plus /

Advanced CPAP Power Station / Can recharge to 80% capacity in under 1 hour.

ECOFLOW is one of my favorite brands, in fact, I’d put them at the top for overall innovation and value. One of the great features of their power stations is you can expand their batteries and add to the stock power station. No other brand does this and it’s genius. You can double the battery power of the Ecoflow River by buying the optional battery. It simply attaches to the bottom of the power station. This allows you scale up your battery life if you decide you need more.

It can easily keep your CPAP running all night. It charges ultra-fast, in 45 minutes to charge the battery from zero to 80%. I would not recommend buying slow charging power stations. You want speed. This is an advanced model by Ecoflow. They’re pioneers in battery technology and theri prices are inexpensive considering what you get. Highly recommend any Ecoflow power station to keep you breathing through the night.

Sustainable Energy and Battery Storage

Clean, green electricity is a fundamental part of creating a more sustainable environment for us and the generations to come. Photovoltaic (PV) solar power is one of the engines driving us forward in this regard. This is centered around efficient battery power storage. A concept that has increased in leaps and bounds over the last 20 to 30 years.

Now, I’m not suggesting that portable power stations are the final solution to all our global problems. These devices are a wonderful use of the best technology we know of. For people who depend on a CPAP machine, portable battery power stations, or solar generators, can be a lifesaver. This is but one of the many applications for these devices.

This is really a brief introduction to the topics and facts that I’ll be discussing. First of all, let’s get down to what products are available. This means a review of the best portable power stations for CPAP, camping, off-grid, and emergency battery backup power.

Best Portable Power Station for CPAP

–— Jackery Series

Best Portable Power Station brand for CPAP. I love Jackery and so do their customers.

If you look on sites like Amazon to see which are the bestselling portable power stations, Jackery comes up tops every time. For high-quality portable battery and inverter power supplies, all the Jackery models are extremely good value for money.

So good is the Jacker reputation, that When Honda (arguably the top portable generator manufacturer) wanted to release an eco-friendly solar generator, they chose Jackery to be their supplier. If you see a Honda portable battery power station, it is actually a rebranded Jackery product. In my opinion, this speaks volumes about the Jackery brand.

The Jackery Explorer range of battery-powered generators have many common features:

• Pure sine wave inverter, supplying clean (low THD), efficient 110V AC power.
• Multiple DC outputs: 12V, USB-A, USB-C, and USB 3.0 on some models.
• High-grade Lithium-Ion Nickle Cobalt (Li-NMC) battery with over 500 cycles up to 80% discharge.
• Battery management system (BMS): prevents overvoltage and short circuit damage. The battery lasts longer and is safer.
• Multiple charging options: 120VAC wall charger, 12VDC car charger, and MPPT solar charger.
• High level of industry certification: FCC, ROHS, UN38.3.
• Comprehensive digital LCD display: Battery level indicator, input watts, and output watts.
• 24-month warranty.
• Compact portable design.  

The difference between the various Jackery Explorer models is mostly about power output and battery storage capacity. There are some minor technical specifications that differ, like the types of USB charging ports available.

Review : Jackery Explorer 160

Features :

• SILENT indoor generator. Purse Sine Wave. Clean Power.
• Equipped with a 167 watt-hour (46,400mah/3.6v) lithium-ion battery pack
• Explorer 160 Outlets : 1x AC outlet (110v : 100w = running / 150w = peak), 1x usb-C port, 2x usb-A ports and 1x standard dc 12v port   
• MPPT Controller : solar ready recharging: pairs well with Jackery solar saga 60w/100w (sold separately), easily get recharged with efficient solar panel.  (long press the button) portable power station,
• 167wh(46.4ah) lithium battery  

OVERVIEW —

The Explorer 160 is the baby of the Jackery family. It is their most compact and lightest portable power station. This is its greatest advantage.

The Jackery Explorer 160 weighs only 3.97 LBS. Dimensions: 7.4” (L), 4.5” (W), 6.7” (H). It is about the size of a really small portable radio. This ultra-compact lightweight design makes the Explorer 160 ideal for backpacking and other situations where storage space and weight is an important concern.

Of course, small and portable means lower output wattage and less battery storage time. The Jackery Explorer 160 can supply 100 watts to the AC outlet, with a 150W surge capacity. Battery storage capacity is limited to 167 watt-hours (WH).

Take it with you anywhere & charge with : SolarSaga 60W

This limited output and battery storage means the Explorer 160 can only be used for low-power devices, for shorter periods. By my calculations, the best you can expect, when using a CPAP machine, is around 5 to 5½ hours on a single charge. In some cases you may not even achieve this.

It’s not really the best for a CPAP machine. For short emergencies or backpacking (when you simply can’t use a larger battery power pack), it can be the most practical solution. The Jackery Explorer 160 is also one of the cheapest options. For some, affordability may be more important than the practical implications.

After the reviews, I’ll provide more information on battery times for CPAP and how to maximize the nights of use per battery charge.

For other, less critical applications, the Explorer 160 is quite effective. You can use a highly efficient, energy star laptop for approximately 10-hours, great for nighttime RV power. It can supply a 5W LED light for up to 29-hours or charge your cellphone about 16 times.

There are quite a lot of versatile DC outlets: 7A, 12VDC, 2.4A 5VDC (USB-A), and 3A 5VDC (USB-C). The 12V battery charging input has a built-in MPPT solar charger, capable of connecting to a maximum 60W solar panel (nominal 12V). This provides a solar charging time that can be as low as 4.5 hours in good sunlight. Using the 120V wall charger, or 12V car charger, you can charge the battery in about 5-hours.

The charger does not allow for through-power, meaning the outlets will not supply electricity whilst charging. The DC input amperage is only sufficient to charge the battery. It, therefore, cannot function as an uninterruptible power supply (UPS).

Review : Jackery Explorer 240

Features :

• Capacity: 240Wh(16.8Ah) lithium battery
• AC Output: 110V —- 200W = running  (400W peak)
• Car Port: DC 12V, 10A, 120 Watt
• USB Outputs (2): 5V, 2.4A (each)
• Weight: 6.6 lb
• Built-in MPPT controllers
• 240 watt-hour (16.8Ah, 14.4V) lithium-ion battery pack.
• Outlets : 1x AC outlet (110V 200W 400W Peak), 2x USB-A ports and 1x DC car port
• PURE SINE WAVE AC outlet
• Smart display to show input power, output power and remaining battery power

OVERVIEW —

You’ve probably guessed from the model number that the Explorer 240 has a larger (240 WH) lithium ion battery. Along with improved battery storage, it also has a more powerful inverter, providing 200W continuous current with a 400W surge capacity. All other technical specifications are basically the same as the Explorer 160. Of course, the size and weight will differ.

The Jackery Explorer 240 weighs 6.6 pounds. Dimensions: 9.05” X 5.24”X 7.87”. It is still a very portable battery power station.

The improved battery spec, certainly makes the Explorer 240 a better power supply for a CPAP. Though, it may not get you through the night with all CPAP models. At best, I calculate 8-hours for a low-watt CPAP, at the lowest power consumption settings.

Because the charge capacity is the same as the smaller model, the Jackery 240 will have longer battery charging times. You’re charging a larger battery with the same input amps. Using the 120V wall charger, or 12VDC car charger, it will take 7-hours to charge the battery. The solar charger has the same 60W maximum capacity as the Explorer 160. This means it will take around 6.5 hours (in good sunlight) to charge the larger 240 WH battery.

For the rest, you can view this as being identical to the Explorer 160. It has the same robust practical design, with a 110V AC outlet, as well as USB-A, USB-C, and 12V DC outputs.

Review : Jackery Explorer 300

Features :

• 2.5 Hours to Full Recharge: Charging by a 90W wall charger and 60W USB-C PD charger simultaneously
• Quick Charge : Can be charged to 80% in only 2 hours. Can recharge Explorer 300 via a solar panel like the Jackery SolarSaga 100W, car outlet or a generator.
• Updated Multifunctional Outputs: 2x AC outputs(300W/peak 500W), 60W PD USB-C, QC3.0 USB-A, USB port & 12V car port.
• MPPT Technology: Provides faster solar recharge rates. Can be quickly recharged from the sun in 5.5 hours with SolarSaga 100W solar panel.
• Weight : Only 7.1 lbs.
• Clean and Safe Power: With clean lithium-ion technology, Explorer 300 is safe and eco-friendly. Battery Management System (BMS) and pure sine wave inverter can safely power your sensitive electronics.

OVERVIEW —

The Jackery Explorer 300 takes quite a big leap ahead of the two entry level models. This is possibly the best in the Explorer series to combine ultimate portability with reasonable output capacity, improved battery storage, and better charging times.

The lithium-ion battery is rated for 293 WH and the inverter can supply 300 watts rated power, reaching a maximum surge output of 500 watts. This gives you greater versatility for AC appliances and should be guaranteed of a full night’s sleep using a CPAP, over 9½ hours for a very efficient (30W) CPAP.

This model has a higher output capacity for the 12VDC outlet, 10A. It also includes a USB 3.0, quick charge, port. AC outlets have increased from 1 to 2. A great advantage is the improved charger capacity for the built-in battery.

VIDEO | A Closer Look at the Jackery Explorer 300

Despite having a lot more battery storage than the 160 or 240, the Explorer 300 is able to charge the battery more effectively – 4.7 hours (wall charger) and 5-hours (12V car charger). The MMPT solar charger can handle more watts, rated for 90W, you can use a 100W panel without damaging the charger. This will give  you an optimal solar charging time of 5.5 hours.

The Jackery Explorer 300 weighs 7.1 pounds with dimensions of 9.1” X 5.2” X 7.8”. Given that this is still a lightweight compact portable battery power station, with enough battery storage to safely supply a CPAP for the whole night, I’d consider the Jackery Explorer 300 as the best compact camping battery power supply for CPAP.

Review : Jackery Explorer 500

---

Ideal for : emergency backup power supply in the event of a power outage. It can supply power to light your lamps, laptops, phones, small fridges, CPAP, and other devices.
Note : The total rated wattage should be under 500w (surge 1000w).

Features :

• Large Capacity 518Wh: Jackery Explorer 500 has a 518 watt-hour (24Ah, 21.6V) lithium-ion battery pack.
• OUTLETS : 1X AC outlet (110V 500W 1000W Peak), 3X USB-A ports, 2X DC ports and 1X car port to power many appliances including : mini fridge, air pump and TV from low power to high power with pure sine wave inverter.
• Engineered for portability. Lightweight at only 13.32 lbs.
• Four ways to recharge : Solar ready with built-in MPPT controller — use the Solar Saga 100W (sold separately) to provide green clean power. Also charge with : wall outlet, car outlet and portable Generator.

OVERVIEW —

The Jackery Explorer 500 is a sort of middle ground between the easily portable smaller models and the more powerful, general use Explorer 1000. The 500 models has, as one would anticipate, a larger 500W/1000W inverter with improved battery capacity (518 WH).

What does this mean for CPAP user times? It will keep a low-watt CPAP running for about 17-hours. You should be able to use the CPAP for 2 nights before recharging the battery.

VIDEO | A Closer Look at the Jackery Explorer 500

Ironically, the Jackery 500 only has 1 X 110V AC outlet. The less powerful Jackery 300 has two. It has the same 12VDC, USB-A, USB-C, and USB 3.0 outlets as the 300 and 1000 Explorer models.

Charging times are a bit compromised. The Explorer 500 has the same input charge capacity as the 300 but utilizes a larger battery. This means it is going to take longer to charge the battery – 7.5 hour AC charging, a whopping 16-hours 12V battery charging, and 9.5 hours using a single 100W panel in good sunlight.

Weight is 13.3 pounds. Dimensions: 11.8” X 7.6” X 9.2”.

The Jackery Explorer 500 is a reasonably priced portable battery power station for it’s capabilities. It is way cheaper than the range topping Jackery Explorer 1000, not too much more expensive than the 300, considering that the Explorer 500 will supply a CPAP for two nights and the 300 won’t do much more than one, this is wonderfully practical power supply for its price.

Review : Jackery Explorer 1000

---

Versatile back-up power that you’ll be able to use in aspects of your life. Definitely one of the best portable power stations for your CPAP. It has enough power to run your CPAP from 55-78 hours making it excellent for camping or your RV trips but beyond that if you’re at home and there’s a long power outage, this will ensure you won’t lose any sleep for 8 to 10 days. Amazing power source in a small package.

Great for :

Features : (Jackery Explorer 1000)

• Massive Capacity: 1002Wh(46.4Ah) lithium battery capacity
• Power : 1000W Rated Power and 2000W Surge Power.
• OUTLETS: 2x USB-C, two USB, 1x DC carport, 3x AC outlets (with the pure-sine wave). Going off-grid and being able to power your cameras, computers, communication devices and also a CPAP and electric grill.
• Clean Power Station: Efficient solar charging with MPPT built-in makes it a solar generator for outdoor activity. Charge the battery to full around 8 hours by connecting two SolarSaga 100W with an adapter cable (package included).
• Portable and Compact:  Weighs only 22 lbs, it is carry-friendly with an easy-carry handle.
• LCD screen : charge/discharge data and battery life status.

OVERVIEW —

The Jackery Explorer 1000 is at the top of the Explorer range. It is excellent for quiet emission-free RV power and home emergency power. If you need a portable power station for CPAP that will keep you going for longer than one night, this could be the ideal solution.

With its 1,000W inverter (2,000W surge capacity), the Jackery Explorer 1000 is a fantastic portable battery station for general use. It is has the AC power output to make it a practical solution for basic emergency power at home during an outage. You can watch TV, use a fan, and keep the lights on for a few hours. The battery capacity has been increased to meet the higher power demand – 1,002 WH. If you’re using it only to supply your CPAP, you could get as much as 33-hours use from the battery before recharging.

VIDEO | A Closer Look at the Jackery Explorer 1000

To cope with the larger battery, the charger amperage has been increased. The 120V wall charger will get the battery to full charge in 7-hours. The 12V car charger is not as capable though, taking around 14-hours to charge the battery. Solar charging capacity is double that of the Jackery 300 and 500, allowing for 200-watts of solar input – 8-hours charge time in good sunlight.

AC outlets have also been increased to three. It has the same 12VDC and USB ports as the 300 and 500 Explorer models (USB-A, USB-C, and USB 3.0). With the up-sized battery and inverter, portability will obviously be compromised to some degree. The Explorer 1000 weighs a fairly hefty 22.04 pounds, dimensions: 13.1” X 9.2” X 11.1”. This is certainly not unmanageable. Easy enough for an RV, using at home, not that practical for backpacking.

The Jackery Explorer 1000 is a big favorite for RV owners. In quiet times, when you can’t (or don’t want to) use a portable gas generator, the Explorer 1000 has the inverter and battery capacity for you to continue with most normal activities. You can a watch a movie on your laptop before going to sleep and then still have enough battery power for to get a god night’s rest, your CPAP will get you through the night.

Goal Zero Yeti X Series

Overview of the YETI X series : Reviews Below…

Best Portable Power Station for your CPAP. The YETI X series is exceptional with many innovative features to make your life easier and power more predictable.

Of the more affordable battery inverter systems, Goal Zero Yeti has always been my top choice. The upgraded Yeti X series has done a lot reinforce this opinion. Since the Yeti X portable power stations are generally more expensive than Jackery or ECOFLO equivalents, I should offer an explanation as to why I see them as better value.

The Yeti power station has a much more extensive product range up to 6,000W (Goal Zero Yeti 6000X). The top models can accommodate external battery packs, allowing for longer battery times. This places them in a similar league to the Tesla Power Wall, just a lot cheaper. In this context, Goal Zero is the economical option.

I also feel that Goal Zero has the most robust design. Even the entry level Yeti 200X has great impact resistance and wonderfully practical recessed handle.

As for basic technical specs, the Goal Zero Yeti X and Jackery portable power stations are very much equals in almost every way:

• Pure sine wave inverter, supplying clean (low THD), efficient 110V AC power.
• Multiple DC outputs: 12V, USB-A, USB-C, and USB PD (2.0).
• High-grade Lithium-Ion Nickle Cobalt (Li-NMC) battery with over 500 cycles up to 80% discharge.
• Battery management system (BMS): prevents overvoltage and short circuit damage. The battery lasts longer and is safer.
• Multiple charging options: 120VAC wall charger, 12VDC car charger, and MPPT solar charger.
• Comprehensive digital LCD display: Battery level indicator, input watts, output watts, and remaining battery time. Varies for different models.
• 24-month warranty.
• Compact portable design.

While Goal Zero offer some amazing, reasonably affordable whole house battery power stations, this is not the topic for this review. We’re reviewing the best portable power stations for CPAP. The larger Goal Zero models are not all that portable. So, for this review, we’ll only be looking at the smaller models that compare favorably to the Jackery and ECOFLO power stations chosen for this review.

If you want something more powerful, I’d highly recommend the 3,000W and 6,000W Goal Zero models. They’re great for all sorts of appliances, including refrigerators and microwaves.

REVIEW : Goal Zero Yeti 200X

Features :

• Yeti 200X Power Station delivers high-quality lithium power, housed in an ultra-portable design made to take anywhere. Yeti 200X is one of the most lightweight power stations on the market and the lightest Goal Zero Yeti to date.
• Power : 120W = running / 200W starting
• 187 Watt-Hours of lithium power and the latest fast-charging technology
• Weight: 5 lbs (2.27 kg)
• High-Speed Charging Solution : Equipped with the latest charging technology, including a high-speed Power Delivery port capable of charging USB-C laptops, tablets, mirrorless cameras, and phones in a fraction of the time.
• Solar Ready : MPPT controller
• Ways to Recharge the 200X :
  • FROM THE SUN  : Recharge from the sun by connecting a compatible solar panel, either the foldable Nomads solar panel like the Goal Zero Nomad 100 or mountable Boulder solar panels like the Boulder 100. The higher the watts of the panel, the faster the charging times.
  • FROM THE WALL : Plug it into the wall. Fully recharges in 4 hours using included 60W power supply, or plug in wth the Yeti X 120W Power Supply to halve that charge time.
  • FROM THE CAR  : Plug into your vehicle’s 12V outlet using the Goal Zero Yeti Lithium 12V Car Charging Cable.
• NOTE: Do not attempt to charge your Yeti Lithium from a 12V source using any other cable. Doing so may cause damage to the unit.

OVERVIEW —

Of the small, most portable battery power stations, I think the Goal Zero Yeti 200X has to be my absolute favorite. I love the wonderfully practical cube-shaped design. I also believe that Goal Zero, in general, is one of the more robust brands in this business.

Comparing the Yeti 200X specs to others in the same class, it has the same basic capabilities. Though it’s charging capacity using 120V AC or solar, is quite remarkable. It is also a winner on the lightweight portability front.

The Goal Zero Yeti 200X weighs a mere 5-pounds, measuring 7.9” X 5.1” X 5.1”. The handle is recessed into the top panel, so it really takes up minimal space when transporting.

The true sine wave inverter supplied 120V output is obviously not much – this is a very small machine. The AC outlet will provide 120W continuously with a surge capacity of 200W. It has the full plethora of DC outlets: 12VDC 10A, USB-A, USB-C, and USB PD, which is pretty much the same as USB 3.0 when it comes to output specs.

The 187 WH battery falls somewhere between the two base models in the Jackery Explorer range. Probably a bit more practical if you want a portable power station for CPAP that is manageable for backpacking and similar situations where bulk and weight need to be kept to a minimum. You can expect a very efficient CPAP to run for around 6-hours. Not ideal, but an improvement on other models that share the same portability.

The charge capacity is amazing, especially for AC and solar charging. It can charge the battery using either AC 120W or 60W, offering charge times of 2-hours or 4.5-hours, respectively. Maximum 12V input allows for an incredible 2-hours and it has a higher solar charge capacity for its size – up to 100W, charging the battery in 2 – 4-hours.

A great advantage to the higher charger capacity is that the Yeti 200X can charge the battery and supply power to the outlets simultaneously (through charge). This is a great improvement on the Jackery portable power stations that only supply enough current to charge the battery (not the outlets). This means that you can use the Goal Zero Yeti portable power station as an uninterruptible power supply, plugged into the main supply whilst supplying inverter or DC power continuously.

Pricing the Goal Zero Yeti 200X by dollar per watt, makes it quite a lot more expensive than similar products from Jackery. The Jackery 240 costs about $1 per watt of AC outlet power, the Yeti 200X costs twice as much. If we use the same method to calculate value in terms of battery storage, the buck per watt-hour ratio is about the same. Essentially, the Goal Zero Yeti 200X costs twice as much as the Jackery equivalent compared the amount of usable power output and runtime that you can expect.

The only area where the Yeti 200X doesn’t beat the competition is when you take a look at the LCD display. It’s very basic, only displaying battery charge as a percentage. This is, to mind, a very minor disadvantage, if any.

I do believe that the Goal Zero Yeti is the better product, though this is only the opinion of one guy. Others may feel differently. In the end, we have to ask ourselves: is the Goal Zero Yeti that much better than Jackery to justify what is effectively twice the cost?

That’s a tough one. Looking at units sold, Jackery wins the popularity contest. Then again, cheaper products usually do.

Jackery is an exceptional brand that you can trust with your money. To learn more about the company visit the Jackery website.

OVERVIEW —

The Goal Zero Yeti 500X is every bit as amazing as the smaller 200X. The design is just as cool with, possibly an even better fold down handle. It obviously has more power and battery storage. For those who love a more comprehensive digital display screen, the Yeti 500X has this too.

The Yeti 500X has a stupendous inverter, delivering 300W continuously and a jaw-dropping 1,200W surge capacity. The battery and charge capacity is also mighty impressive – 505 WH, with a maximum charge capacity of 180W. The 12V car charger (regulated at 120W) will take 4.5 hours to fully charge the battery. You have the ability use 120V 60W or 120W charging, offering recharge times of 10-hours or 4.5 hours, depending on the wall charger output. Solar charging beats all others, up to maximum of 200W, which will charge the battery in is a little as 3-hours, up to 6-hours in less favorable conditions. Like all the other Yeti models, the 500X allows for simultaneous charge and discharge.

So, how does the Goal Zero Yeti 500X perform when supplying a CPAP? Really great – almost 17-hours using a CPAP that draws 30W.

DC outlets cover all bases – 12VDC (10A), USB-A, USB-C, and USB PD. It has a large display screen with beautiful graphics. At a glance, you can check the battery discharge status, input and output watts, as well as percentage time remaining. Power to weight ratio is pretty good, the Yeti 500X weighs 12.9 pounds. Dimensions: 7.5” X 11.25” X 5.8”.

For a super tough, delightfully practical, and technically advanced portable power station, the Goal Zero Yeti 500X receives 5 gold stars, by my rating anyway. It terms of buck per watt and watt-hour battery storage, it is slightly better value for money than the smaller Yeti 200X but still the more expensive option compared to the other two brands in this review.

OVERVIEW —

If high AC output is what you’re after, then the Goal Zero Yeti 1500X is going to be your number choice of the portable power stations selected for this review. The inverter delivers 2,000W continuous power and 3,500 peak watts. That’s enough to run a large refrigerator and then some. It also has a cool party trick, the Goal Zero 3.0 App, offering remote access to a wealth user info and functions.

Two 120 AC outlets give you access to the huge amount of power at your disposal. Power is stored in a very capable 1,516 WH lithium-ion battery. That’s enough battery power to keep a full-size refrigerator running for up to 28-hours. At least, that’s what the manufacturers claim. I think this a very optimistic, best case scenario, but still very impressive.

VIDEO | A Closer Look at the YETI 1500X

If you’re looking at only supplying a CPAP, you can go for days, around 50-hours. Wow! That’s only the half of it. This model has, like its larger counterparts, a port to chain Goal Zero expansion modules. Allowing you link up more batteries to extend your power storage.

To provide reasonable recharge times for this massive battery capacity, they’ve fitted a really potent charger for both AC and solar. AC charging can be as high as 600W, charging the single internal battery in only 3-hours. Solar charging is even better – up to 1,200W. In good sunlight, you can charge the battery in only 3-hours. If you’re using expansion modules, increasing your battery watt-hours, charge times will be longer relative to the total battery capacity.

All other specifications are of the same high standard as other Goal Zero Yeti models: 12VDC outlet, along with USB-A, USB-C, and USB PD. It has the same great LCD display as the other top Yeti models.

With all that power and battery storage, you’ve probably guessed that the Yeti 1500X is quite heavy and not all that compact. It weighs 45.64 pounds with dimensions of 15.25” X 10.23” X 10.37”.

The Goal Zero 1500X has to be crowned the king of portable power stations. Although it is quite bulky and heavy for some, it is ideal for an RV. Quite simply a super amazing, and wonderfully versatile quiet, emission-free power supply for just about any application – home or vacation, even a jobsite.

REVIEW : ECOFLOW RIVER Indoor Generators

Easily one of the Best VALUE Portable Power Stations for your CPAP.

EcoFlow are the proverbial new kids on the block in the high-tech world of portable power supply. When they started out I, the ever curious tech-head, did a lot of research into the company. Its origins and ambitions.

Features :

• 3 x 600W AC OUTLETS AND 288Wh CAPACITY The EcoFlow RIVER can power up to 10 devices simultaneously. With 3 pure sine wave AC outlets, the EcoFlow RIVER can power some devices up to 1800W with the X-Boost mode on. With a capacity of 288Wh, the EcoFlow RIVER provides enough juice to run essential devices for hours, depending on the actual output. 
• RECHARGE FROM 0% TO 80% WITHIN 1 HOUR With EcoFlow’s patented X-Stream Technology, the smart inverter enables a fast rechargeability that takes less than 1 hour to charge from 0% to 80%, and it gets fully charged in 1.6 hours. You can switch to a quieter charging condition by turning on the “Quiet Charging” status on the APP.
• COMPATIBLE WITH 80% HOME APPLIANCES The RIVER can power some devices up to 1800W with the X-Boost mode on, which lets you power about 80% of essential devices like kitchen appliances and DIY tools. Use devices below 1200W for the best product use. 
• FIT YOUR NEEDS, NOW AND LATER Double the capacity from 288Wh to 576Wh with an Extra Battery, the modular design of EcoFlow RIVER, is the power that grows with your needs. Designed for mobility, the 11 lbs solid yet lightweight EcoFlow RIVER is slightly larger than a toaster, which is perfect to take out. You can easily double the capacity of the EcoFlow RIVER from 288Wh to 576Wh by integrating with an Extra Battery.

OVERVIEW —

This is truly modern, youthful, and vibrant brand. Millennials on a mission. The founders have won great recognition, including the Forbes top 30 under 30. All this is great on paper and glossy media presentations. What does it mean for us as consumers?

In some ways, I’d say the EcoFlow river is technology taken to the extreme. A lot of really clever technology and wonderful practicality. There is a lot of out the box thinking that has gone into this advanced portable power station.

River PRO Power Station : Plenty of power for your CPAP

For starters, they’ve decided to go with a one size fits all approach. There aren’t a bunch of different models with all sorts of watt outputs. You basically have the option of the EcoFlow River 370 travel bundle which is a fairly limited, lightweight, portable power station, designed to be carried anywhere. The other option is the full-size EcoFlow River which comes in a variety of formats: the standard River, River MAX, or River Pro. The different models are basically the same, with different battery extensions to increase battery storage.

The EcoFlow River is very reasonably priced, probably the best value when compared to either Goal Zero or Jackery when you consider the type of technology you’re getting.

VIDEO | Learn More about the EcoFlow River Series

The River base model uses a 600W inverter with a 288WH lithium battery, giving you just over 9-hours battery time for a 30W CPAP. You can upgrade to the River MAX at any time which is basically an additional battery module, doubling your battery storage.

On the face of things, it looks pretty much the same as the others. A comprehensive digital display shows watt input and output, battery level and time remaining before the battery is depleted. It has 3 X 120V outlets, a 12VDC outlet, and all USB ports – USB-A, USB-C, and USB 3.0. It also has a pretty advanced App for smartphones and tablets.

Where the EcoFlow River shows true ingenuity is in the vastly improved battery charging times and their revolutionary X-Boost function. Though I’m not too sure if the latter is all that great. I’ll explain why later.

First, the good news. You can charge the battery in only 1.6 hours using the wall charger, 3-hours with a 12V car charger, and 2.4 – 5 hours using a 160W solar panel.

►Ultra-Powerful : Delta EF ECOFLOW — 1800W run / 3300W start

---

What really makes the River different to all others is the X-Boost function which is, in my opinion, not as great as it appears to be. It is basically an improvement on the inverter computer controls. The actual inverter remains a 600W unit with a pretty impressive 1,800W surge capacity. However, when you press the X-Boost button the inverter miraculously supplies 1,200W continuously. According to all laws of energy, this should be impossible. How do they do it?

Actually they don’t. All this boost mode does is bypass the normal overload trip and allows the inverter to lower the voltage to keep supplying the higher watts. This causes the voltage output to drop to just above the rated safe voltage for 120V equipment. It can be a little over 60V. In the end, your 1,200W appliance is only supplying 600W. Energy cannot be created or destroyed. I really don’t see this as great advantage. If the engineers design an appliance to run at 120V, the voltage supply should always remain within 10% of this.

While the X-Boost may be a talking point, it is not as great as it is made out to be. In the end, the EcoFlow River is a good portable power supply and very practical. Just not exceptional as the advertising hype may make it appear. It weighs a very reasonable 11-pounds and is wonderfully compact: 11.3” X 7.3” X 7.7”. The warranty is the same as the others in this review – 2-years.

Getting the most from CPAP when using a portable power supply

When I calculated the hours that a CPAP can run using the portable power stations reviewed, I took the best possible energy consumption. It may vary on the type of CPAP you own and how you use it.

If you want to get the most from your battery, you want to consume the lowest wattage. It would be a good idea to obtain watt specs and choose the lowest watt CPAP if you want the best battery times.

How many watts does a CPAP draw?

Generally, a CPAP consumes anything from 30 to 60 watts of power. For my calculations, I worked on the base wattage – 30W.

There are ways to maximize your energy efficiency to increase battery time for your CPAP.

Use a DC power supply

Most CPAP machines run on a 12VDC supply. The 120V wall power supply that comes with your CPAP is a basically a transformer that coverts 120V AC power to 12V DC. Some CPAPs use a different voltage (18 VDC or 24 VDC). Since most portable power stations include a 12VDC outlet, it makes sense to use a 12VDC CPAP.

By connecting the CPAP to the 12VDC outlet, instead of the 120V inverter outlet, you eliminate the energy loss that occurs when converting power form AC to DC or vice versa. It makes no sense converting the DC battery current to AC, then back to DC to run your CPAP. You’re losing energy all the way down the line, reducing the battery efficiency.

Set your CPAP to lowest power setting

Your CPAP may have numerous options, like dehumidifier or heater. These are certainly nice conveniences, but they consume additional energy. If your main objective is to get the maximum time from your battery, turn all additional functions off. Read your CPAP owner’s manual carefully to see what is the most basic, lowest consumption setting that you can use.
