Guide to DuroMax and Champion Portable Generator Models

The model number of DuroMax generators correspond to their starting watts while the Champion’s correspond to their running watts

guide to models of duromax vs champion generator
DuroMax XP4850EH vs Champion 3800-Watt Dual Fuel RV Ready Portable Generator with Electric Start

The more appliances you want to power using your portable generator, the higher the peak and running watts you require. The peak or starting watts refers to the power needed to start your appliances while the running watts is the power it needs as it continues running once it has stabilized. For reference, water heaters or air conditioners (10000 BTU) require 3,000 starting and running watts while fridges and freezers typically require 1,200 starting watts and 700 running watts. If you only want to power LED lights or routers, generators with low peak and running watts are good enough.

DuroMax and Champion carry different portable generators with different peak and running watts. Here are some of their popular models:

DuroMax Portable GeneratorsChampion Portable Generators
XP4000S1200-Watt Portable Generator
XP4400E, XP4400EH3500-Watt RV-Ready Portable Generator
XP4850EH3800-Watt Dual Fuel RV Ready w/ Wheel Kit

XP10000E, XP10000EH4000-Watt RV Ready Digital Hybrid
XP12000E, XP12000EH5500-Watt Portable Generator (with Wheel Kit)

The number on DuroMax portable generator models is their peak/starting watts. As for the letters found at the end, they correspond to certain features of the generator:

  • S: Gas-powered (typically has a recoil starting system)
  • E: Gas-powered with electric start
  • EH: Dual-Fuel technology which means they can either use propane or gas

Contrary to the DuroMax model numbers, the numbers on the Champion generators correspond to their running watts. Champion’s models are also more straightforward at a glance as the name itself will tell you the features found in each generator. However, there are different variants of each model that can sometimes make it confusing. When choosing Champion portable generators, make sure that you pick one that is certified for use in your state. If the generator is not CARB-compliant, it cannot be used in California. Meanwhile, most DuroMax generators are both EPA and CARB certified.

Engine and Power

Both offer dual-fuel technology; the DuroMax has slightly higher peak watts but the Champion has a bigger engine

These portable generators work well for use for RV, job sites, or home power back-up

The DuroMax XP4850EH, with 3850 running watts, and the Champion 3800-Watt generator with 4275 peak watts, are solid portable generators for emergency back up. They can power most medium-sized appliances and home essentials with no issues. While the Champion has a bigger 224-cc engine than the 204-cc engine of the DuroMax, the latter can handle starting more appliances better as it has higher peak watts. However, their running watts are not that different when used with gasoline.

If you intend to use propane though, the DuroMax performs slightly better with 4,608 peak watts and 3,658 running watts. In comparison, the peak watts of the Champion is 4,275 watts while its running power is at 3,240 watts. Both brands recommend a 20-gallon propane tank to be used with these portable generators.

When it comes to their gasoline tank size, the DuroMax has a slightly bigger 3.96-gallon capacity which gives it a runtime of up 10 hours at half its load. Meanwhile, the 3.4-gallon gas tank of the Champion allows it to run for up to 9 hours on gasoline.

Starting System and Panel Features

Both portable generators offer electric start; the Champion has more outlets than the DuroMax

Both these DuroMax and Champion portable generator models feature electric start, but the Champion’s touch start is a lot more convenient than the DuroMax’s mechanism. The Champion’s design, where its black outlets contrast the bright yellow panel, makes it easier for the user to find where things are.

The power panel of the DuroMax XP4850EH houses the following outputs:

  • (2)120V 20A GFCI Outlet
  • 120V/240V 30A Twist Lock

Meanwhile, the Champion 3800’s power panel houses the following outlets:

  • (2) 120V 20A Volt Guard-Protected
  • 120V 30A RV
  • 120V 30A Locking Outlet

Portability and Additional Features

Both the DuroMax and the Champion come with a handy wheel kit but they have different included accessories and tools

Their wheels and handles make it easier to transport these portable generators

While they are portable, these generators are heavy enough that they require wheels for better mobility, making it easier to move them even when alone. Both the DuroMax and the Champion come with a wheel and handle kit that can be installed easily. They both use “never-flat” wheels, but the Champion’s look sturdier and better-built.

If you get the Champion 3800-Watt Dual Fuel Generator, you’ll get an engine oil and propane hose with your purchase so you don’t have to buy them separately. However, the Champion doesn’t come with tools. Meanwhile, the DuroMax XP4850EH comes with tools and a funnel, but it doesn’t include the oil and propane hose.


Both the DuroMax and the Champion generators are solid choices, but the DuroMax XP4850EH offers better value for your money

Lasso Brag

You can’t go wrong with either the DuroMax XP4850EH or the Champion 3800-Watt Dual Fuel Generator. Both are reliable, sturdy, and can last for years. However, since the DuroMax is more affordable and features a higher peak and running power, it simply offers better bang for your buck. Even if you add the extra expenses for the oil and the propane hose, the DuroMax still costs less than the Champion.
