Zoom on the Champion 100331

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

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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 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 conventional pull-start mechanism.

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

As the 100331 has a relatively high THD (<20%), it is not recommended to use it to power sensitive electronic devices.

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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Champion generator is RV Ready.

Portability

The Champion 100331 has a conventional, open frame design, of the following dimensions: L23.2 x W18.1 x H19.6 in, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

As the 100331's weight is only 99.2 lbs, it can follow you and your power needs anywhere. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

It is also possible to purchase the official wheel kit (opens in a new tab) to help you transport the 100331 more easily.

Features

Panel of the Champion 100331

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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind. Champion's built-in surge protector (Volt Guard™) safeguards your equipment and appliances against voltage spikes.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Champion 100331 also is packed along with the following 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, so it is adequate 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).

  • Regarding its weight, the Champion 100331 only weighs in at 99.2 pounds, which means it's one of the lighter generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 68 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 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 Predator 4375, which is able to run for around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator reaches an estimated fuel consumption of 0.38 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

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.
