Description

The DuroMax XP4000S has a 208 cc (7 hp) DuroMax OHV 4-stroke engine that runs on gasoline and puts out 120V, 3,300W while running, and 4,000W at its most powerful. The generator has a noise level of 69 dBA, which is less than an office. It is started with a pull-start mechanism. With a full tank, the XP4000S can run for about 12 hours at 0.5 load (using about 0.33 GPH of fuel). This is because it has a 4 gallon fuel tank. Since the THD of the XP4000S is about 12%, it is not a good idea to use it to power sensitive electronics.

Outlets

On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (L5-30R) outlet. Even though this DuroMax generator isn’t quite RV Ready, its L5-30R receptacle makes it easy to connect to an RV with an L5-30P to TT-30R adaptor.

Features

The control panel of the XP4000S has a convenient voltmeter that enables you to quickly and easily monitor power output at any time to help you keep tabs on its status and activities. The device’s light indication will also show if the oil level is too low in addition to this information. The generator’s built-in fuel gauge makes it simple, quick, and easy to detect the fuel level. You can use the gadget with confidence because to its security features, which include an automated low oil shut-off and overload protection (circuit breaker). The DuroMax XP4000S also includes a tool kit and funnel in addition to the necessary paperwork and an owner’s manual to help you start the generator promptly. As a supplementary purchase, an official storage cover is additionally offered.

Mobility

The DuroMax XP4000S has a standard, open frame with the dimensions L23 x W17 x H18 in, This frame gives it support and lets it be lifted off the ground. The design works well in rough places and for hard outdoor use. The 92-pound weight of the XP4000S makes it easy to take it anywhere. The generator is also easier to move because it has an open frame, which makes it easy to grab and move. You can also buy the official wheel kit, which will make it easier to move the XP4000S.

  • We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
  • For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
  • Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.

About the Manufacturer

Small American power equipment manufacturer Duromax is headquartered in Ontario, California. Pumps, engines, pressure washers, and power generators are among the many goods in which Duromax excels. The company’s only concentration in this area is on portable generators, primarily those with small and medium power outputs as well as dual fuel devices. Although construction of Duromax generators is outsourced to other countries, they are designed and serviced in the US. DuroMax, which was established in 2003, has begun to emerge as a significant force in the market for power generators.

Warranty Information

A warranty covers the DuroMax XP4000S for up to 3 years. This warranty may not cover all parts of the generator or may only cover certain parts. Check out DuroMax’s warranty policies if you want to know more about the warranty on DuroMax generators. You can also call their customer service line at 1-844-DUROMAX (844-387-6629).

DuroMax-XP2300iH

Key Features

  • Wattage (Gas): 2,300 W / 1,800 W
  • THD: < 3%
  • Noise Level: 52 dBA
  • Fuel Type: Dual Fuel (gasoline/propane)
  • RV Ready: No
  • Run Time@ 25% load: 13 h
  • Run Time@ 50% load: 7 h
  • Weight: 50.6 lbs

We are proud of our independence and have no ties to manufacturers. To maintain our objectivity, we do not accept free products. Our income is generated by advertising fees paid by retailers for qualifying purchases.

Description

The dual-fuel technology in the DuroMax XP2300iH gives it 120V, power, and a lot of different uses. When powered by gasoline, it has a running wattage of 1,800W and a maximum wattage of 2,300W. When powered by propane, it has a rated 1700 watts and a peak of 2150 watts. Also, the generator can be connected to a second unit to make more power because it comes with a parallel kit. Switch On Demand is a feature of DuroMax that lets you switch from gasoline to propane or propane to gasoline while the generator is running. The inverter generator has a noise level of 52 dBA, which is just a little louder than a conversation at home. It is started with a pull-start mechanism. With a full tank of gas, the XP2300iH, which has a fuel capacity of 1.1 gallons, can run for up to 13 hours (fuel consumption is approximately 0.08 GPH). It can run for up to 38 hours on propane (on a 20 lbs tank – propane consumption around 0.12 GPH). The XP2300iH makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 3%, you can safely plug your sensitive electronics into the AC outlets.

Outlets

On the control panel, there are 3 AC outlets for: Duplex 120V 20A (5-20R); 120V 30A (L5-30R) receptacle. Also, it has 2 DC outlets: one USB-A port and one USB-C port. This makes it easy to charge devices like cell phones and tablets. This DuroMax generator isn’t quite RV-ready, but it has an L5-30R receptacle that makes it easy to hook it up to an RV with an L5-30P to TT-30R adapter.

Features

The control panel of the XP2300iH has a digital data center that tells you things like the frequency, voltage, lifetime run hours, fuel level, and power output. This helps you keep an eye on its activity and status. The device’s light indicators will also show if the generator is ready, if it is overloaded, or if the oil level is too low. From a safety point of view, the product has a circuit breaker for overload protection and an automatic shut-off for low oil, so you can use it without worry. The XP2300iH also has the CO Alert carbon monoxide shut-off feature from DuroMax. If CO levels get too high too quickly, the generator will shut down automatically, a red light will come on, and the engine won’t start again for 5 minutes. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. The DuroMax XP2300iH comes with a propane hose, a tool kit, and a funnel, as well as the usual paperwork and an owner’s manual to get you up and running quickly.

Mobility

The DuroMax XP2300iH looks better than a typical open frame generator because it has a closed inverter generator (L22 x W14 x H20 in). This kind of design is the most modern and easy way to make power for fun. Since the XP2300iH weighs only 50.6 lbs, you can take it anywhere you need power. Also, its two 4.5-inch-diameter wheels and telescoping handle make it easy to move once it’s on the ground.
