DuroMax XP4850EH Description

The DuroMax XP4850EH is a dependable generator that offers plenty of power and long running time. Featuring innovative technologies, such as Dual Fuel and MX2, this generator is powerful and long-lasting.

The XP4850EH is one of the few generators that can efficiently operate multiple devices simultaneously. This makes it safe for operating home appliances, running tools on a job site, or camping in your RV.

Power and Runtime

Fitted with Dual Fuel technology, this unit runs on either liquid propane or standard gasoline. This offers versatility, especially in demanding conditions or emergencies.

The amount of power it provides is perfect for almost all standard RVs. You can operate multiple appliances at the same time without fear of overheating.

Yet, the XP4850EH does much more than just make camping fun. This unit is capable of powering your home appliances in case of a power outage or any other type of emergency. Plus, you can take it on job sites where it can safely power heavy tools and machinery.


The fuel tank capacity for gasoline is a little less than 4 gallons. When the XP4850EH is powered by gasoline, it has a rated wattage of 3850W and a starting wattage of 4850W.

Running the generator at half load, you can enjoy over 10 hours of continuous running time.


The suggested propane tank size is 20 pounds. While using propane, this generator provides a rated wattage of 3658W and a starting wattage of 4608W.

When operating at half load on propane, the runtime is almost none full hours. The best thing about cleaner-burning liquid propane is that it creates fewer emissions. It’s one of the few fuel sources considered to be environmentally friendly.

Outlets and Ports

The full power panel on the XP4850EH features several outlets so you can make the most of your generator. Having options makes it versatile and a handy piece of equipment to have around.

  • The XP4850EH panel includes:
  • 2 120V Ground Fault Circuit Interrupter (GFCI) outlets for household appliances
  • 1 120/240V 30A twist-lock outlet for a no-fuss connection to a breaker box
  • 1 12V DC outlet for charging external batteries
  • Voltmeter for monitoring power output
  • Low oil indicator light
  • Key start switch


Let’s explore some additional features of the DuroMax XP4850EH.


One of this generator’s biggest advantages is its portability. With 10.5-inch solid rubber wheels and front handles, you can easily move the unit from one place to another. The handles also fold up for added convenience.

The open steel frame enables the unit to stand raised above the ground. This makes it more suitable for demanding outdoor job sites and rough environments.

MX2 Technology

One of the versatile features of the XP4850EH is Duromax’s patented MX2 Technology. This innovative design allows you to make the most of the power receptacles. One option is to power the generator using both 120V and 240V at the same time.

Another option is to operate using only the 120V receptacle. This way, the generator will run at full power for longer, which is what RV owners ideally use to power their appliances.

Having this option is one of the reasons why the XP4850EH is long-lasting. It also makes the generator more a reliable choice.

Overload Protection

The XP4850EH has a smart sensor to protect it from burning out. When the sensor detects low oil levels, the generator automatically shuts down.

In addition, the panel consists of a circuit breaker, known as an Automatic Voltage Regulator (AVR). It helps protect the motor from overheating and potential malfunction. AVR also prevents any possible damage that may be caused by a power overload or voltage spike.


The DuroMax XP4850EH features an air-cooled 210cc 7-horsepower 4-stroke engine. Its overhead valve (OHV) boosts airflow while getting rid of exhaust gas.

The cast iron sleeves provide better protection against harsh environments. Plus, they help provide a smoother operation.

Hybrid Start System

To operate the DuroMax XP4850EH, you have two choices: electric or pull-start. To use the pull-start, there’s a starter rope to engage the recoil start system.
The second option is to simply press the start-up button. It turns on the generator smoothly and quickly.

The one drawback is that it doesn’t come with a wireless start system. Some people prefer the convenience of powering their generators remotely.


The DuroMax XP4850EH comes with basic documentation, including a user-friendly owner manual. The generator also comes with the following accessories:

  • Toolset
  • Spark plug wrench
  • Oil funnel
  • DC charging cables
  • Wheel and handle tool kit

Size and Weight

The DuroMax XP4850EH is an efficient and durable generator. It’s designed for reliability, safety, and portability. It has all the basic features any consumer looks for in a generator.

Its dimensions are 22 x 24 x 21 inches, which is quite compact compared with other generators on the market. Yet, it doesn’t take away from its high performance and long lifespan.

Boasting a hefty weight of 122 pounds, the XP4850EH is constructed with a solid metal open frame. This makes it capable of standing up to the roughest of work environments.

Noise Level

With a noise rating of 69dB, the XP4850EH runs at a pretty low operating level. On the decibel scale, a rating of 69 refers to a noise level that’s slightly above a normal conversation. It’s not the quietest on the market, but it still manages to run pretty much unnoticed in the background.

There are four rubber mounts that support the unit. They reduce noise levels by absorbing some of the vibrations caused by the running engine. This results in a smoother, quieter operation.


The DuroMax XP4850EH complies with both the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). It also comes with a spark arrestor, which makes it safe to use in forest areas. All DuroMax generators follow strict regulations for environmentally-friendly operation.
