Duromax XP4850EH Review

Duromax XP4850EH

The Duromax XP4850EH is a unique generator in that you have the option to use gas or cleaner-burning propane. This dual fuel generator provides a consistent 3,850 watts of power and at peak, 4,850 watts of power. 10W-30 oil is recommended for this generator. The DuroMax Dual Fuel Technology allows you to increase the generator’s lifetime by being able to run on propane from a BBQ tank or main line.

Continuous power

The XP4850EH comes with a 210 cc, 7 HP 4-stroke air-cooled, cast iron-sleeved engine that can produce a total of 4,850 surge (or max) watts and 3850 rated (or running) watts, which is good enough to power a few of the biggest home appliances during a power outage. It boasts a runtime of 20 hours when fueled by propane, and approximately 8 hours of runtime on a full (4-gallon) fuel tank at 50% of maximum load.

Excellent control panel and outlets

The power panel on the Duromax XP4850EH is very good, and comes with (2) 120Volt 20 Amp 3-Prong Outlets and (1) 120V / 240V 30 Amp Twist Lock outlet (NEMA L14-30 3 Pole 4 Wire). It also features a circuit breaker, large volt meter and a convenient 12V DC output. The control panel is easy to use and includes an oil warning light, volt meter, circuit breakers, and an easy key-start switch.

Rugged construction

The Duromax dual fuel generator has a heavy duty frame with 4 point rubber mounts for the motor ensuring a smoother and quieter operation. It also has a wheel kit with front handles which make it easy to move and transport.

It can be used for camping to power lights and your appliances or even be used at tailgating parties, however the one complaint or negative aspect we have noticed is that is quite loud. The build quality and construction ensures smooth and reliable operation of this generator in any situation.
