DuroMax XP4400EH Portable Generator Review

A Midrange Power Source Especially Designed for RVs

The DuroMax XP4400EH is reportedly designed to work best with recreational vehicles (RV). It’s meant to be easy to move around. It runs on both gasoline and propane, offering you flexibility when it comes to fuel choice. And with a starting wattage of 4,400 W and a running wattage of 3,500 W, it’s supposedly capable of providing power to a wide range of essential tools and appliances. But does this model live up to its hype?

Engine capacity and wattage

At only 208 cc, the XP4400EH engine is slightly smaller than those fitted into the other models in the DuroMax portable generator product line. But don’t underestimate it because of its size. It can pack a punch just as solid as that delivered by bigger-engine models. With a starting wattage of 4,400 W and a running wattage of 3,500 W, the XP4400EH is a power source you can rely on.

Exactly how can you rely on this DuroMax generator? If you’re an RVer, you can hook up your camper and have enough power for your lights, refrigerator, battery chargers, and other appliances you need to make your campsite comfortable. If you’re looking for something to use in case of emergencies, this machine can keep your air conditioning and essential home appliances running.

However, if you intend to plug-in appliances and electronics that require heavier power loads, such as an electric stove, washing machine, or water heater, the XP4400EH may not be able to produce sufficient power for your needs. You may be better served by a generator with a bigger capacity.

The engine on this DuroMax model is also relatively quiet, thanks to the built-in mufflers meant to minimize its noise and emissions. Its noise rating is only 69 decibels, supposedly about as loud as a hairdryer. It’s entirely possible to have a decent conversation even when you’re near this machine when it’s running, and it’s not loud enough to disturb the neighbors next door or on your adjacent campsite.

To keep this engine running smoothly, it’s recommended that you break it in with several oil changes before first use. DuroMax recommends SAE 10W-30 oils for its machines. Other engine oils may not have the right viscosity or may be too abrasive for DuroMax’s engines.

Fuel consumption

Thanks to DuroMax’s Dual Fuel Technology, the XP4400EH can run on both gasoline and propane. This allows you more flexibility—you can follow your fuel preference or use whatever is available. On gasoline, this generator can run up to 11 and hours at half load. Its tank can hold up to almost four gallons of gasoline. If you hook it to a 20-gallon propane tank, on the other hand, it can generate continuous power for nearly 10 hours.


Another feature that adds to the flexibility of this DuroMax model is its ability to switch output. You can use it for both 120 V and 240 V at the same time. Or, if you prefer to, you can channel the generator’s full power to just using 120 V. All you need to do to make this happen is to hit the voltage selector switch. You’ll find three outlets on this machine’s control panel—two 120V 20A GFCI outlets and one 120/240V 30A twist-lock outlet. There’s also an idle control to slow down the engine when it’s not being used, as well as a circuit breaker. The generator also automatically shuts down when low on oil.

Ideal usage

According to the DuroMax official website, the XP4400EH is specifically designed to satisfy the power needs of campers and RVers. We believe it can do the job it’s made for and sufficiently powers up small to mid-range camper vans and fifth wheels. After all, it can generate enough electricity for lights, a small outdoor grill, a fridge, and other small appliances. However, it may be a bit of a stretch to say this generator is adequate for large RVs with all the luxury perks. If that’s your RV, you may need a bigger machine for it.

As a backup generator for your home or worksite, this model works well. You can use it to keep the lights on and your basic appliances running in case of outages, or plugin your power tools for your tasks at hand. Just don’t try to run your air conditioning or space heater along with everything else.

What users say about the DuroMax XP4400EH

The general consensus for this DuroMax product is it runs well as a backup generator for homes and work sites. Some users said they liked how quiet this model is, especially when it runs on propane.

However, there are users who reported that this model displays issues when running on propane. Among these issues is shutting down without apparent reason after a few minutes of being connected to a propane tank. One user also stated that they encountered electrical problems while powering their fifth-wheeler RV with this generator.
