  • RV travellers who wish to upgrade their experience to another level

Power & Run Time

The Champion 100331 in use

The Champion 100331

The Champion 100331 houses a 224 cc Champion OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3650W along with a peak wattage of 4500W.

With a noise rating of 68 dBA (less noisy than an office), the generator features 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 includes the following 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

With its dimensions of L23.2 x W18.1 x H19.6 in, the conventional, open frame design of the Champion 100331 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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

Features

The 100331's control panel

The 100331's status and activity may be monitored conveniently via the control panel, as it features an Intelligauge meter showing you voltage, frequency and lifetime hours.

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.

Apart from the typical documentation and a user manual, which lets you start it right away, the Champion 100331 also is packed along with the following accessories: funnel and oil.

Emissions

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

Moreover, it features a spark arrestor, making it usable 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 is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 68 dBA. If you are concerned with noise, check out the Westinghouse iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As for its autonomy, the 100331, with an autonomy of around 9 hours at a 50% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000, which is able to run for around 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 dynamic 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.
