Zoom on the Champion 100891

In summary, the Champion 100891 is a portable generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Champion 100891 in use

The Champion 100891

With its dual-fuel technology, the powerful and versatile Champion 100891 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 7500W along with a peak wattage of 9375W. While propane-powered, it provides 6750 rated watts and 8400 starting watts.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner).

With a fuel capacity of 7.7 gallons, the 100891 can operate for around 10 hours at 50% load using gasoline (fuel consumption around 0.77 GPH), or for around 5.5 hours (on a 20 lbs tank - propane consumption around 0.85 GPH) using propane.

The 100891 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<20%).

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

This Champion generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as the 100891 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The dimensions of the Champion 100891, which are L28.8 x W27.7 x H26.1 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 207 lbs. However, its challenging mobility is solved by its wheel kit (⌀9.5") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Champion 100891

The 100891's control panel

The control panel of the 100891 includes an Intelligauge meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it. Champion's built-in surge protector (Volt Guard™) safeguards your equipment and appliances against voltage spikes.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Champion 100891 also comes with some accessories: propane hose, oil and funnel are included.

Emissions

The Champion 100891 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The Champion 100891 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100891 compare to generators of similar power (between 7000 and 8000 W).

  • As its weight is 207 pounds, the Champion 100891 falls in the expected weight range of the devices in the 7000-8000 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 74 dBA. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA8000iSF, one of the least noisy generators similarly powerful as this one, rated for 65 dBA.
  • As the 100891 offers around 10 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 9000, which is able to run for around 13 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.77 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA8000iSF, with a fuel consumption of 0.52 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 7000-8000W generators, the Champion 100891 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
