Zoom on the Champion 100331

In a nutshell, the Champion 100331 is a compact portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners in need of an emergency backup power for their essentials

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Champion 100331 in use

The Champion 100331

The Champion 100331's core is the 224 cc Champion OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3650W and a peak wattage of 4500W.

The generator is rated for a noise of 68 dBA (less noisy than a normal conversation). Its starting mechanism is based on a simple traditional pull-start mechanism.

The 100331 can operate for around 9 hours at 50% load with a full tank (fuel consumption around 0.38 GPH), due to its fuel capacity of 3.4 gallons.

Outlets

The control panel provides the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

This Champion generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The design of the Champion 100331 is a typical, open frame, with the dimensions of L23.2 x W18.1 x H19.6 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.

The 99.2 lbs of the 100331's dry weight enables you to use it anywhere you will ever need. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

Panel of the Champion 100331

The 100331's control panel

The 100331 and its control panel include an Intelligauge meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

As for its security measures, the device features a Volt Guard™ overload protection and an automatic low oil shut-off, letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Champion 100331's package also includes these accessories: oil and funnel.

Emissions

The Champion 100331 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Champion 100331 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100331 compare to generators of similar power (between 3500 and 4500 W).

  • As for its weight, the Champion 100331 weighs only 99.2 pounds, making it one of the lighter generators in the 3500-4500 rated wattage category. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • Because this generator emits noise as low as 68 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Regarding its autonomy, the autonomy of the 100331, reaching around 9 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Standing at an estimated 0.38 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Champion 100331 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
