This Champion 100231 is an excellent example of high quality 5000 watt generator, but the details reveal much more versatility since it’s a dual fuel generator, which means it runs on either gas or propane. When running it off gas it provides 6900W of starting power and 5500W or running power. This won’t run your entire house but it can run a few essentials. Have you determined how much power you need? Most people don’t do the calculations. Back to the Champion 1000231 — on propane it gives you 6250 starting watts and 5000 running watts. Is that enough for you?

Intro | 5000 Watt Generators
A 5000-watt generator hits the perfect sweet spot between portability and performance. It is powerful enough to run your air conditioning, small kitchen appliances, power tools, etc. during an outage, but not so unwieldy that you can’t move it around. Most of these portable generators come with wheels and folding handles, so you don’t need a 2- man crew to move them around. Plus, they are built tough with wraparound tubular steel frames and heavy-duty motors that are rated for commercial use.
In this articles we take a look at the top rated 5000 watt generators worth buying for 2023, while we are still deep into the global pandemic and most people are looking to spend their money wisely. Let’s hope that 2021 is much better than 2020. It’s been a hard time for so many of us. Just remember, that things will get better. Hang on there. We’re all in this together.
Exceptional VALUE : 5000W Running — WEN GN6000
Depending on what your requirements are, you might prefer one 5000W generator over the other. They all have their pros and cons, and even the build quality can vary significantly which is why you should always do your research before purchasing one. Features like electric start and a good automatic voltage regulator are very important. The former adds a layer of convenience and the latter is necessary for stable power delivery to your tools and appliances (since you obviously don’t want your devices to get damaged).
Some folks are looking for more industrial generators, with rugged and heavy steel bodies that can take a beating. Pro- grade air filters, strong engines, etc. However, thanks to modern technology and manufacturing processes, you can get generators of nearly the same quality in the consumer segment these days. Take Westinghouse WGen series generators for example — these are built rugged, have a bunch of outlets, and are equipped with reliable motors that keep running for several years with minimal maintenance. That’s the reason I included not one, but two Westinghouse WGen generators in this article. Westinghouse is one of my favorite brands when it comes to portable generators for homeowners. They mix reliability, ruggedness, features, and affordable pricing into one complete package. You just can’t go wrong with Westinghouse, and their warranties are pretty solid too.
VIDEO | A Closer Look at the DuroMax XP5500HX
Maybe you don’t want ultimate reliability and ruggedness. If you’re looking for a generator that will be used just once or twice a year (maybe for running tools or during a storm), check out some of the cheaper models from DuroMax. The strength of DuroMax is their ability to offer generators with really high power ratings for very low prices (relatively speaking). You also get some really nice dual-fuel generators from DuroMax that I highly recommend for anyone looking to use their portable generator as a home backup system. Propane burns cleaner than gasoline, is easier to store, doesn’t gum up the carburetor, and can be found readily during an emergency at most hardware/ big-box stores (like Walmart).
DuroMax XP5500HX : 5500W Dual-Fuel Generator
One of the best 5000W generators for the money. Yeah, I know, it’s a a little more than 5000W.
Features :
- RUNS ON GAS OR PROPANE : Runs on gasoline or liquid propane, offering the freedom and flexibility of fuel choice.
- EQUIPPED WITH CO ALERT : An advanced technology to keep your family safe and sound from harmful engine fumes
- DIGITAL COMMAND CENTER : Track voltage output, operating frequency, and maintenance hours.
- MX2 TECHNOLOGY : Double the 120v power for appliances and RV’s.
- All-new control center with a digital multi-meter, USB outlets, a front-facing fuel interface and Duromax’s exclusive MX2 switch.
- Combines two 19 Amp 120-Volt circuits into 1 powerhouse 38 Amp circuit, the digital multi-meter displays voltage, frequency, total hours run and hours until the recommended maintenance
- Designed with an innovative carbon dioxide alert system that will automatically shut down the generator if an unsafe level of carbon monoxide is detected. This alone makes this a ‘must buy’ generator. Safety first. Far too many lives are lost from carbon monoxide poisoning.
- Powerful 210 cc OHV-V Duromax engine and features all copper windings designed to make your generator last for years
- Fully loaded power panel includes two 120-Volt GFCI household outlets, one 120-Volt/240-Volt 30AMP twist-lock outlet
- Individual circuit breakers, an oversized noise reducing muffler with a built-in spark arrestor and a low oil sensor
OVERVIEW —
Not only is the XP5500HX one of the most affordably priced 5000+ watt generators on the market, but it also packs a neat CO sensor. This sensor automatically shuts down the engine if dangerous levels of carbon monoxide are detected. If you’re working at a jobsite or using this generator for home backup, the CO detection system can come in super handy. CO poisoning is no small matter, most accidental deaths caused by generators happen because people use them in enclosed spaces or without appropriate ventilation. It is an odorless, colorless gas that replaces the oxygen in your red blood cells, causing brain failure. By the time you realize it, it’s probably too late. That’s why you should always operate the generator at a distance of at least 25 or 30 feet from the nearest living space/ window/ door.
The XP5500HX is what I would go with if I wanted an affordable home backup generator. Especially in a storm-prone area, because when the gas station is closed you can still buy/ refill propane tanks at a hardware store. Plus it doesn’t hurt that propane is better for the environment since it burns cleaner and releases less greenhouse gasses. This generator is also equipped with a digital panel that lets you track voltage, amps, and other important data in real-time. Everything from the air filter to battery can be accessed and maintained/ replaced very easily thanks to the open frame design. And it is all powered by a 210cc DuroMax OHV engine which has proven itself to be extremely reliable.
Highlight features- CO sensor that automatically shuts off the generator when carbon monoxide levels get too high, and a MX2 switch which combines both 19amp 120V circuits to double the amperage for heavy 120V loads (large power tools will benefit from this).
When Money is not a Concern, which 5000W Generator is Best?
The Winner Goes to — ►Honda EM5000S
As far as Honda goes, it’s a brand impossible to beat. I’d have to say that any Honda is the very best generator for the money, and in this case, the EM5000S is the best 5000W generator.
Looking to purchase a 5000W generator with the intentions of running it for extended periods of time on a jobsite? Well, it has to be extremely reliable. And if you depend on it to make money, there is no need to go with a cheap DuroMax if your budget allows you to get a Honda. Think of it as a long-term investment, you spend the extra cash now and you’ll be rewarded with less downtime and less money spent on maintenance during the long run. Plus, the power delivery on this thing is stellar- very stable and no sudden spikes even when you connect a new heavy-duty load.
It is designed with contractors and campers in mind, although you can definitely use it for home backup too. This is one of the most fuel-efficient and quiet 5000W generators (not including inverters), which should come as no surprise. It’s Honda, everyone knows their generators are the best (although a bit on the pricier side). They have the best engines with unparalleled reliability, and really good noise suppression. This model uses an iGX commercial grade motor with computerized controls for maximum stability and fuel efficiency. Plus, it has a 3-year commercial/ residential warranty and 120/ 240V operating modes for running heavy draw loads.
Note : There’s also a EM5000SX model which has a CO sensor and Bluetooth capability (you can monitor the operation and control functions via the Honda My Generator app). The carbon monoxide sensor should put this generator at the top of your list because it may save your life one day. Thousands of people die from carbon monoxide poisoning every year and it’s shocking to me that it isn’t law for generators to include a CO sensor on all generators.
More than 900 people died of carbon monoxide poisoning from portable generators between 2005 and 2017, according to the Consumer Product Safety Commission. CPSC data also indicate that an estimated 15,400 people were treated in emergency rooms for portable generator-related carbon monoxide poisoning during that period.
NPR : Carbon Monoxide Poisonings Spike After Big Storms. Portable Generators Are A Culprit
I’m sure someday they will be on every generator but that doesn’t help the lives that could have been saved — today, tomorrow and next week. Every life matters. Please manufacturers, include carbon monoxide sensors in every generator. It’s for the good of humanity and should help you sleep at night.
Highlight features- Honda iGX commercial grade engine, 11.2hr runtime at half-load, electric start, and lower noise (63 to 66dBA) compared to other 5000W open-frame generators.

OVERVIEW —
“Probably the best all-rounder of any 5000W portable generator, the Westinghouse WGen5300v delivers incredible value for money. It is capable of 5300 continuous watts, with surge wattage up to 6600. This should be plenty for basic home backup since you can power more than just the TV and lights. It will easily run a 1/2hp sump pump and 10,000 BTU window AC at the same time. The WGen5300v is both RV and transfer switch ready.”
I can definitely see the appeal for a generator such as this among homeowners. It isn’t exactly a premium product with top of the line commercial grade components like Honda, but then again- it is 1/3rd the price of a comparable Honda generator. And despite that, you can run this thing day in and day out without having to worry about the motor or alternator breaking down.
It is solidly built, and packs plenty of power. 5300 running watts should be more than enough to handle a couple of crucial circuits along with some kitchen appliances, lights, and the TV. You can run your AC, electric range, and dishwasher simultaneously without tripping the overcurrent breakers on this generator. It will even power your water heater and furnace fan without any hiccups.
As I have mentioned at the start of this article, 5000 watts is the sweet spot for portable generators. Whether we’re talking RVs or home backup, this is the ideal amount of power to run a reasonable number of appliances. Not quite commercial/ industrial grade, but not so small that you hit max capacity with just a coffee maker and TV set.
WGen5300v : Westinghouse has been making generators since 1886
So, how about the build quality? After all, it doesn’t matter how often you use your generator if it doesn’t start up when you need it the most. Say you want a generator for home backup because you live in a storm-prone area. You barely need it once or twice a year, and more a week or two at most. However, it is very important that this generator starts up without any trouble during those one or two weeks. Is the WGen5300v something you can trust in such a situation?
Yes, in fact it is designed for home backup with a durable OHV 274cc 4-stroke Westinghouse engine. This engine has a cast iron sleeve which enhances lubrication, and thus the longevity of the internal components. It is also transfer switch compatible, so you can power essential circuits safely without being in danger of harming any utility workers down the line. Just keep the generator’s L14-30R outlet hooked up to a transfer switch, and when the mains go down you simply turn on the WGen5300v. Select the circuits you want to power on the breaker panel and you’re good to go. The WGen5300v will deliver all- night power since it has a really nice 13.5hr runtime at 50% load. All this is from a fuel tank that isn’t even super large, just 4.7 gal (18L). There are other 5000W generators with 5 or even 6 gallon fuel tanks which don’t get runtimes like these. That tells you how efficient this 274cc Westinghouse engine is.
If I were to knock any points off, it would be for the lack of an electronic starter. Not something that is super complicated or expensive to implement in a generator like this, plus nobody would mind the extra 20 or 30 bucks since this is already so cheap. Now, it should be noted that with the standard recoil starter you don’t need more than 1 or 2 pulls (even in cold weather). There are some pros to not having electronic start, like reduced overall weight and ease of maintenance. But the weight isn’t an issue anyways, this generator is pretty light for its class. Not saying that affects the durability in any way, because the whole chassis is made from heavy gauge tubular steel with two bars running across the top that protect the generator from heavy falling objects.
The structural rigidity is really good despite this whole thing weighing only 132.5lbs dry. Maybe that’s why they went with slightly lighter duty wheels and axles because they know this generator won’t need the tougher stuff. It is light enough for the default axle and wheels to handle it, even on uneven terrain. And it has all the usual safety features — over-current protection, low oil auto shutoff, grounding, etc.
Pros:
- Excellent value for money with 5300 running watts and 6600 surge watts
- All the outlets you could possibly need, including a TT-30R 30amp RV outlet and L14-30R 120/ 240V twist lock transfer switch outlet (all outlets are protected from dust and moisture with rubber covers)
- Never-flat transport wheels
- Tubular steel frame with a foam grip folding handle
- Long 13.5hr runtime at 50% load (beats even some 5000W Honda generators)
- Digital VFT (Voltage, Frequency, Time) display
- Solid AVR keeps THD under 23 percent (good enough since this is no inverter generator, those have THD values under 3 to 5 percent)
Cons:
- No electric start
- No low oil indicator

“While the WGen5300v is the most basic model in the WGen5300 lineup, the 5300s is one tier up in terms of both price and features. It has electric start, which is super convenient if you don’t want to stay outside yanking on the recoil starter cord. Like during a storm or blizzard. Perhaps that’s why this is part of the Storm Series…”
Overview
The WGen5300s is marketed as part of the “Storm Series” indicating that it is designed for home backup in storm-prone areas. But there is nothing structurally different between this and the base 5300v that makes the more expensive model somehow better at handling rough weather or home backup loads. It is essentially a 5300v with a battery and electric starter, plus a markup on the cost.
Is that electric starter alone worth the extra money? I don’t think so, at least for most people looking to buy a generator in this price range. You could simply get a 6000W or 5500W generator for the same money, minus electric start. You could run an extra appliance or two by spending a few seconds more starting the generator. Or just get the WGen5300v, it is one of the best generators for the money. Sacrificing a tiny bit of convenience gets you more bang for your buck.
However, I understand there are folks who just lack the physical strength to pull a starter cord. Especially senior citizens, users with back problems, etc. And that’s fine, this generator is just right for you if you are one of those people. If you don’t want to stand outside in the snow or rain pulling on a cord, then an electric starter is just perfect. But understand that you’ll have to ensure the battery is charged at all times otherwise your electric starter becomes useless.
Tip: I suggest that you go for one of the dual fuel models if you have the money to buy a WGen5300s. A dual-fuel model actually makes a lot more sense as a storm backup generator than a simple WGen5300v with an electric starter strapped on. Check out the WGen5300DFv and WGen5300DF. The WGen5300DFv is the dual fuel model without electric start and costs less. The WGen5300DF has electric start. Both of these will run on propane, although their power output will drop from 6600/ 5300 watts (peak and continuous) to 5800/ 4800 watts if you’re using propane. Propane is easier to find during an emergency when the gas station isn’t working, and it is also easier to store (you don’t need fuel additives to increase the shelf life).
Pros
- Excellent value for money
- Rugged and reliable with a 247cc OHV cast iron sleeve engine and tubular steel roll bars
- Easy to maintain
- Easy to transport
- RV and transfer switch ready
- Electric starter simplifies operation
- Reassuring 3-year warranty with lifetime tech support
Cons
- No GFCI outlets
- The price increase isn’t reflected in the performance or build quality, it’s pretty much just a 5300v with an electric starter and battery (still great value for money, just not as great as the base 5300v)
DuroMax XP5500E | Top Rated 5000W Generator
“If you want a jobsite generator that can double as a home backup generator, this is it. The DuroMax XP5500E delivers 5500 peak watts and 4500 running watts, enough to power any tool or home appliance. It has GFCI outlets and is both EPA as well as CARB compliant so you can use it in California.”
Overview:
DuroMax makes a big deal out of their MX2 technology which is designed to deliver the maximum possible amperage through the 120V receptacles. Basically, it combines both 120V circuits within the generator, each of which carries up to 18.75 amps. Combine both, and you can get 37.5 running amps from a single 120V outlet which is very useful if you want to run heavy power draw tools. Welders, planers, etc. will draw that kind of power. And another huge benefit to having this generator on a jobsite is its GFCI (Ground Fault Circuit Interrupter) outlets. Basically, it detects when there is a ground failure and protects you from getting electrocuted. GFCI breakers are extremely fast, acting and closing the circuit within 1/40th of a second. Short circuits, equipment malfunctions, insulation failures are things that can happen on a jobsite and a GFCI outlet is pretty much required in any serious jobsite generator. It is also helpful for home backup, just something that is nice to have whether you’re at home or on the jobsite.
The engine isn’t quite Honda tier, but is still very reliable and is produced in USA (California). The emissions are lower compared to most conventional open-frame generators, since the XP5500E is both EPA and CARB compliant. Despite its name, it is not a true 5000 watt generator, instead it delivers 4500 running watts and has a surge rating of 5500 watts. DuroMax generators are reliable and sturdily built, this one is no exception. It also carries a 3- year warranty.
In terms of outlets, you get the standard 120V duplex and a 30amp twist lock which can operate in both 120V/ 240V mode. There is no TT-30R RV outlet, but you can still use it on a camper or RV (it just won’t be as convenient as a Westinghouse WGen5300). All outlets are GFCI protected, but there are no dust covers. Runtime is 8.92 hours at half load, from a 3.96 gallon gas tank. Significantly lower than a Westinghouse WGen5300v or WGen5300s (but still quite good). This is a lighter and more compact generator than the Westinghouse WGen5300 (as it should be, we are comparing 4500 running watts against 5300). Instead of a digital VFT display, you get an analog voltmeter. And there is a 12V DC outlet, something you don’t find on many generators in this segment.
Pros
- Reliable 225cc 4-stroke OHV engine designed and manufactured inhouse by DuroMax in California
- GFCI outlets
- MX2 technology allows for maximum amperage from a single 120V outlet (37.5 running amps at 120V, better than any other generator in this class)
- EPA and CARB certified
- Total Harmonic Distortion of just 10-12% under load, which is miles ahead of any other conventional open frame generator (for reference, Westinghouse WGen5300v has a THD of over 20 percent)
- Electric start (battery included)
- 12V DC output
Cons
- No oil included within the box
- Instead of a digital VFT display you get an analog voltmeter

OVERVIEW —
“The DuroMax XP5500EH takes everything good about the XP5500E and adds dual- duel capability so you can run it on either propane or gasoline. And you get this upgrade for minimal extra cost over the base XP5500E model. In my opinion, the XP5500EH is seriously worth considering as a storm backup generator for your home.”
Overview:
The DuroMax XP5500EH is a dual fuel model which means it can run on either gas or propane. Propane is readily available at any hardware or home improvement store. Plus you can store it forever since it doesn’t require any fuel additives to maintain stability. And since it burns cleaner, the internals of your generator engine will stay clean meaning you spend less money on parts and maintenance in the long run. Propane also produces less greenhouse gasses, making it better for the environment.
I see this as a worthy upgrade over the XP5500E, well worth the little bit of extra money that you pay for the EH model. Unlike the WGen5300s which delivers very little over the WGen5300v and costs significantly more. If you’re looking for a home backup generator that can run the fridge, AC, TV, electric range, blender, sump pump, etc. this is it. You can easily get through the night on a single tank as long as you stay at or under 50 percent load (4500 running watts on gas, 4275 running watts on propane).
Pros
- Dual fuel capability (Gas or Propane)
- Electric start
- MX2 technology for 37.5 running amps from the 120V outlet
- GFCI outlets
- L14-30R twist lock outlet so you can hook up the XP5500EH to a transfer switch (excellent if you’re using it for home backup)
- Despite having a sturdy steel roll cage and heavy duty axles, this generator weighs only 124lbs dry
- EPA and CARB certified, made in USA
Cons
- No oil included
- Just an analog voltmeter instead of digital VFT (Voltage Frequency Time) display
What Can You Power With A 5000W Generator?
If we’re talking 5000 continuous watts, you can power a large refrigerator, freezer, 1 ton AC, 1/2hp sump pump, TV, and a bunch of LED lights all at the same time. As for power tools, you can easily run a 1hp air compressor or 7.25” circular saw off a 5000 watt generator. You can run both at the same time, provided you start the compressor first before you plug in the saw. Since the compressor will have an extremely high starting wattage of around 4000 watts. You can also run any drill, grinder, or table saw that you want.
With generators it is important to understand the difference between running and starting watts. Running watts is the amount of power your generator can reliably supply for continuous operation of an appliance/ tool. Starting or surge watts is the amount of power it can manage for short bursts of time. Starting watts is always higher than running watts. This is essential to power appliances like compressors, pumps, motors, etc. that require an initial burst of power to get rolling before their power draw settles down. Heaters, computers, ovens, hair dryers, etc. are steady loads which means their starting and running wattage requirements are similar. Resistive loads have similar starting and running watts. Capacitive loads have starting wattages up to 2 or even 3 times higher than running wattage. Refrigerators for example draw the most power when their compressor cycles on, otherwise they stay under 70 to 80 watts most of the time.
When powering multiple appliances, don’t try to start them together. First, you plug in the one with the highest starting and running wattage. Then you proceed downwards from that. While calculating power requirements, add up the running wattages of all appliances and tools you feel the need to run simultaneously. Add in an extra 20 to 30 percent on top of that, just for future proofing and to help your generator last longer. With generators, you never want to run them constantly at 100 percent load. This will wear down the engine and burn out components faster. Ideally, you want to stay within 50 to 70 percent load for maximum efficiency and long-term reliability. Plus, it helps keep noise levels down since your generator’s engine won’t have to constantly struggle if you are running reasonable loads.
Note: If you can’t find the power figures for an appliance, look behind or underneath for a sticker mentioning the amps and volts. Multiply both of them to get watts.
Inverter vs Conventional Generator
Inverters are designed with clean power in mind, and they run quieter. Unlike a conventional generator which has a simple alternator design, inverters have a lot more poles and winding. As a result the 3-phase power produced by an inverter generator alternator is at extremely high frequencies (around 20KHz). Inverter generators create more power per revolution of the alternator.
And the energy is produced in 3 different stages. First stage is the AC power from the alternator. In the second stage, this AC power is converted to DC by running it through a rectifier. This smooths out a lot of the irregularities. Then this DC power is converted back to AC by running it through an inverter which shifts it to the appropriate voltage and frequency for final output. The end result is a current which is much closer to what you get from the wall through your utility company (pure sine wave).
THD values on even the most basic inverter generators don’t exceed 3 percent (compared to over 20 percent on regular generators). This is clean enough to be used by sensitive electronic appliances. Since the inverter and alternator within an inverter generator allow it to modulate current and voltage on the fly, it doesn’t have to run its engine at a constant 3600 rpm like conventional generators. This results in smaller engines, less noise, and more fuel efficiency. However, there are downsides. Inverters are significantly more expensive compared to conventional generators, watt for watt. And they don’t scale beyond 5000 to 7000 watts. You won’t find a whole lot of high wattage inverters that are capable of powering entire homes during an outage. And thanks to the additional electronics packaged into an inverter generator, it is significantly harder to repair at home unless you have extensive experience with complicated circuits.
Note: Recently, a new type of generator called a “hybrid” has been gaining popularity (hybrids are also known as open-frame inverter generators). Hybrids combine the strength of both inverters and conventional generators into one package. They cost less than a true inverter while generating much cleaner power than a conventional generator (at lower noise levels too). And these hybrids are also priced very reasonably. A nice example of a hybrid is the WEN GN625i, it’s priced similarly to 3000W inverters but delivers 5000 watts of continuous power with 6250 surge watts.
