Power & Run Time

The Champion 100331 in use

The Champion 100331

The Champion 100331 is powered by a 224 cc Champion OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3650W as well as a peak wattage of 4500W.

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

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

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

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

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. This type of design is ideal for tough environments and heavy outdoor use.

As the 100331's weight is only 99.2 lbs, it can follow you and your power needs anywhere. Moreover, grabbing and moving this product is made even easier by its open frame design.

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, which displays voltage, frequency and lifetime hours.

From a security standpoint, the product offers an automatic low oil shut-off and a Volt Guard™ overload protection, allowing you to use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Champion 100331 also comes with several accessories, including: 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).

  • In terms of its dry weight, the Champion 100331 stands at only 99.2 lbs, meaning that is one of the lighter devices of 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.
  • 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.
  • The 100331’s autonomy is somewhat low end compared to devices of its power range, as it reaches only around 9 hours at 50% load on a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, 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. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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.
