  • Durability 9.1
  • Ports and Outlets: 8.8


The Duromax XP5500EH is like a younger brother to the Duromax XP13000EH and Duromax XP12000EH, with all the power, durability, reliability, and fuel efficiency at a smaller scale. Additionally, the Duromax XP5500EH is highly portable and easy to carry around.

The unboxing experience was nice; we got along with the package.

  • Wheel and handle kit

After filling the machine with oil using the electronic switch, the generated starter ran very smoothly within 10 seconds.

This machine was specially designed for camping and outdoor activities, keeping portability in mind.

It is EPA and CSA-certified and equipped with a hybrid engine, allowing users to switch between gasoline and propane, which is very convenient.

This machine has a dual-fuel engine that can generate up to 4500 W on gasoline and 4225 W on propane, based on our team load test.

The difference is not great, so users can switch between fuels based on their needs without cutting off any real power.

People often choose propane since it burns the cleanest, and the difference between the two is not that significant.

It is also RV-ready. You can choose to operate between 120V and 240V.

Like other models in the XP series, the Duromax XP5500EH also comes with an ECO mode.

Eco-mode automatically adjusts the engine’s RPM according to the power needed to save fuel and reduce noise.

Design and Convenience [RATINGS: 8.8]:

Duromax XP5500EH weighs around 124 pounds with 25 x 22 x 22 (L x W x H) inches in dimensions. It is somewhere in between a heavy and a light camping generator.

It is easy to move around with the help of a carry handle and wheels. It features both manual and electric start, but you’ve got to purchase the battery separately.

We also liked the neat and clean design of the control panel. It features two 120V 20A standard outlets, one 120V 30A twist lock, an MX2 switch, a propane inlet, and an analog voltmeter.

MX2 allows getting the maximum power out of both 120V receptacles.

Based on our tests, the analog meter on the control panel is about 95% accurate.

Noise Test [RATINGS: 7.6]:

According to the manufacturer, the Duromax XP5500EH generates close to 69 dB of noise. We tested that theory by putting this generator under 55%, and the following are the results:.

  • From 20 feet away, at 55% load on eco-mode, the noise was 72
  • From 30 feet away, at 55% in eco-mode, the noise was 69

It is not a super quiet generator, but it is not bad at all. If you use it at least 20 feet away from your home, the noise won’t disturb you.

Fuel-Efficiency/Runtime Test [RATINGS: 9.1]:

The XP series of Duromax generators is all about high-quality performance based on very good fuel efficiency. We also tested that theory, but put the XP5500EH under our fuel-efficiency test, and the following are the results:

  • Gasoline: At 50% load (2250W), the generator lasted for 9.2
  • Propane: At 50% load (2138W), the generator lasted for 8.1

The above-mentioned results are magnificent. The best part of the test was that the engine was not getting too hot.

Load Test [RATINGS: 9.9]:

The major test we consider for any generator to pass is the load test. We tested Duromax XP5500EH, and here are the results.

  • The generator produced 4490 watts of gasoline.
  • Constantly, it was able to give off 4505 to 4515 watts even after adding a heat lamp to an already-loaded generator.
  • On propane, the total load was 4225W, and the machine was able to generate 4215
  • With an extra heat lamp on propane as well, the final result was 4220W before the overload alarm went off.

This is a beast of a dual-fuel generator. It is extremely powerful.

  • Refrigerator (600–800 watts)
  • Freezer (similar power requirements as a refrigerator)
  • Microwave oven (1000–1500 watts)
  • Lights
  • Television (50-200 watts)
  • Computer and monitor (300–800 watts)
  • Modem and router (50 watts combined)
  • Fans (box fans, ceiling fans, etc.)
