Hi and welcome to the DuroMax Dual Fuel 4400 Watt Portable Generator.

From protecting your family during a power outage, to taking power on the road for camping, powering your RV, all Duromax generators are there for you.

It’s designed to be extremely easy for anyone to start, just a turn of the key or a pull of the EZ-recoil will give you a quick, reliable start every time!

With its 4-gallon fuel capacity this environmentally minded EPA approved unit will run a full 8 to 12 hours on a single tank of gas and even more on Propane!

With the DuroMax XP4400EH you have the flexibility to operate on either gasoline or liquid propane. It only takes a few seconds to switch over from regular gas to propane. With the flexible line, you can easily hook up any size propane tank including the one from your barbeque. Unlike gasoline, propane can be stored for years without going bad, and it costs less, saving you money.

The Full featured power panel was designed to offer the perfect balance of power and functionality with its engine shutoff switch, volt-meter, circuit breaker and power outlets.

It includes 2 fully protected 120v 20-Amp, & (1) 120V/240V twist-lock outlet to supply power to all of your appliances – including Sump-Pumps, refrigerators, microwaves, air conditioners and more.

DuroMax Generator’s exclusive RV Switch has a Power Amp Boost that harnesses the full power of your generator by combining the two 15A 120v circuits into one powerhouse 30A circuit to provide you with the double the 120v power for heavy loads – such as commercial power tools, electric pumps, small air conditioners, or your RV’s demanding power needs.

Every XP4400EH comes with the portable wheel and handle kit at no extra cost. The no-flat semi-solid tires ride like air tires, but will last for years longer.

With DuroMax Generators, we have you covered. On the job site, a DuroMax generator is indispensable. The XP4400EH Generator gives you the ability to power tools and lights even in the most remote location.

The unique exhaust design coupled with the frame dampening allows it to run at a comfortable 69 decibels. That’s quiet enough to hold a conversation next to it without raising your voice and it’s suitable for campgrounds and public parks.

All DuroMax Generators are packaged in a rugged box, with foam padding to guarantee a safe arrival. DuroMax generators will last you for years, and are always backed by a One-Year Factory Warranty.

The DuroMax line of generators includes models to power a wide range of uses. From our 4000 watt generator to our top of the line 10,000 watt power house, DuroMax generators are built to last. Rugged…durable….dependable…power when you need it!
