Note from Editor :

Do you go with a dual-fuel generator or a regular gas model? Dual-fuel always costs a little more but the option to run off of propane is tempting. Personally, I think a dual-fuel model is a safer bet over the long-run, especially if you expect to use your generator for emergencies. The main reason is that propane can be stored indefinitely. It doesn’t expire, whereas gas has a limited shelf life, making it difficult to store reliable in the long-run.

Overview | DuroMax XP12000EH 

Let’s take a look at what makes the DuroMax XP12000EH a serious contender to be rated as one of the best gas powered portable generators available.

Hybrid Fuel Capability

The DuroMax XP12000EH can run on either regular gas or propane gas. The versatility of dual-fuel capabilities has several advantages and we’ll be looking at that in more detail later in the article. So keep reading.

Robust and Powerful Engine

To deliver enough reliable current to keep your home powered up in an emergency or keep machinery running on a construction site, you’re going to need a dependable, powerful engine. It uses an 18 horse power 457 CC engine, with an Over Head Valve (OHV). The cylinder sleeves are cast iron and bearings are made from steel. The locally built engine is both powerful and reliable, giving you trusted reliability when you need it most.

Excellent Build Quality

A portable gas generator has to be built solidly to handle tough conditions in any working environment. The DuroMax XP12000EH is built from the highest quality materials and to the most stringent quality control standards. The engine is mounted using four-point rubber mountings, this ensures smooth running and durability, even under the toughest working conditions.

Safety Features | DuroMax XP12000EH

When it comes to your safety there can be no compromise and the DuroMax XP12000EH is equipped with every conceivable safety feature one could want from a gas powered generator. Let’s take a look at what safety features it provides.

Current Overload Protection

The DuroMax XP12000EH has a main overload circuit breaker and individual circuit breakers for each of the power outlet sockets. This prevents any damage caused by circuit overload or short circuit. The circuits breakers can be reset when the power overload has been corrected.

Oil Level Alert

When the oil level runs low a warning light will come on and the engine will switch off. This prevents overheating and any damage that may be caused by running the engine with too little oil.

Spark Arresting Muffler

The muffler is designed to prevent sparks that can pose a fire hazard. The spark arresting muffler meets the requirements set by the US Forrest Services and complies with the regulations of most states for use in places where there is a fire risk.

Easy to Transport

The DuroMax XP12000EH comes complete with a transportation kit which includes large rubber wheels and handles for great portability.

Easy to Use | DuroMax XP12000EH

So many people who have used a portable generator with a recoil (pull) starter will know how tedious this can be. The good news is that the DuroMax XP12000EH is equipped with an electric starter, so it will start with the turn of a key. To make things better, it also comes with a recoil starter, so you can still start it if the battery runs low – giving you the best of both worlds.

The user panel gives you great functionality without over complicating things with switches and gauges that you don’t need or understand. It has two regular 120V plug outlets like you’d find in your home and a 30A 120V twist-lock outlet which is very handy for RV owners. There is also a high current 120V/240V outlet, this can be connected via a transfer switch to your main power distribution board.

It has a volt meter, so you can keep an eye on the voltage and ensure that your appliances are not running the risk of damage from over or under voltage. There’s also a handy 12V outlet for charging batteries.

Low Noise

One could never expect a generator capable of delivering such a large amount of power to be completely silent. However, the brilliantly designed muffler on the DuroMax XP12000EH means that the noise level is surprisingly low for a machine of this caliber.

Overview —

Essentially they are the same basic generator with the same engine and current output. They look the same and perform the same function. There is one fundamental difference, the DuroMax XP12000EH has a hybrid due-fuel engine. While this makes it more expensive than the DuroMax XP12000E, it does come with the advantage of being able to use propane gas. So if you’re wondering why should you pay more for this single difference, now is the time to look at the advantages of using propane gas.

Compact Storage

Propane gas is stored in a compressed state, meaning that a single cylinder the size one would normally for a gas barbeque, can run the DuroMax XP12000EH for 20 hours at 50% average current load. By comparison, the 8 gallon gas tank fitted to the generator will give you 10 hours for the same power usage.

Safe Transportation and Storage

Propane gas is stored in a totally sealed container, this means there can be no spillage when being transported or stored. There is also no fumes emitted from the container that can ignite. Because the container emits no fumes, there is no unpleasant odor that is usually associated with gas storage containers.
