Zoom on the Champion 100331

In summary, the Champion 100331 is a compact portable generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Champion 100331 in use

The Champion 100331

The Champion 100331's design includes a gasoline-fueled 224 cc Champion OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3650W and also 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 conventional 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.

Since the 100331 has a somewhat high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the upcoming 4 AC outlets:

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Champion generator is RV Ready.

Portability

The Champion 100331 has the following dimensions: L23.2 x W18.1 x H19.6 in. In combination with its conventional, open frame design, they provide support and allow 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. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

If you wish to transport the 100331 more easily, you may also consider purchasing the official wheel kit (opens in a new tab).

Features

Panel of the Champion 100331

The 100331's control panel

To help you monitor the 100331's status and activity, its control panel is equipped with an Intelligauge meter, which displays voltage, frequency and lifetime hours.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and a Volt Guard™ overload protection.

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: funnel and oil.

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).

  • 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 you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 68 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cummins Onan P4500i, whose lowest noise levels reach just 52 dBA.
  • Autonomy-wise, with around 9 hours on a full tank at a 50% load, the 100331 is on the low end when compared to other generators of a similar power output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000X, with 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 has an estimated fuel consumption of roughly 0.38 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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.
