Description

Champion's 2500-watt inverter generator is ultra-lightweight, making portable power more convenient than ever. Rely on the 79cc engine and enjoy a quiet 58 dBA for up to 11.5 hours of run time.

Zoom on the Champion 100889

In a nutshell, the Champion 100889 is a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • DIYers who wish to improve their efficiency with tools

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 100889 in use

The Champion 100889

The Champion 100889 houses a 79 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1,850W along with a peak wattage of 2,500W. In addition, as it is parallel capable (parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 53 dBA (just slightly more noisy than a refrigerator).

The fuel capacity of 1.1 gallon allows the 100889 to operate for up to 11.5 hours with a full tank (fuel consumption around 0.1 GPH).

The 100889 produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Additionally, it features 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy. Since a dual port USB adapter is included with the unit, you will also be able to use the DC receptacle to conveniently charge electronics such as mobile phones and tablets.

Portability

The Champion 100889's characteristic encased inverter generator design (L17.3 x W11.5 x H17.7 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

Weighing just 39.5 lbs, the 100889 can be considered a lightweight portable generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed on-the-go. Further convenience is provided by its handle (molded in the case), as it allows you to carry it effortlessly.

Features

Panel of the Champion 100889

The 100889's control panel

The device’s light indicators will display if the generator is overloaded, its oil levels are insufficient and the generator is ready.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Champion 100889 also comes with several accessories, including: dual port USB adapter, funnel, oil and battery charging cables. The official storage cover and running cover are also available, as separate purchases.

Emissions

The Champion 100889 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

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

Product Video

The Champion 100889 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100889 compare to inverter generators of similar power (between 1500 and 2500 W).

  • Weight-wise, the Champion 100889 has only 39.5 lbs, which renders it one of the lighter inverter generators which produce 1500 to 2500 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 34.2 lbs.
  • As this inverter generator can emit noise as low as 53 dBA, it finds itself in the average expected noise for this kind of power. 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 Honda EU2200i, whose lowest noise levels reach just 48 dBA.
  • With a run time of up to 11.5 hours at 25% load, the 100889 has one of the higher run times, compared to its similarly powerful peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP2300iH, boasting with up to 13 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator, with an estimated fuel consumption of just 0.1 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the DuroMax XP2300iH. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from these interactive charts, when compared to other 1500-2500W inverter generators, the Champion 100889 is on the average side of the price range.

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

    I agree with all the observations and specs. There is a fuel valve as part of the on/off switch. I discovered you can run the carb completely empty if you turn the off knob in the off position direction, just shy of it shutting off. It will run until the carb runs empty and stop. Then turn it the rest of the way off. I prefer to run the fuel out as it leaves virtually no residue to gum up the carb. If you are putting it in deep storage like a year or more, I would drain the fuel from the tank, siphon etc, then run the tank and carb dry in normal run mode to get all the fuel out of the tank lines and carb. Fuel stabilizer is also a must, especially if you want to leave fuel in the tank for ready use in emergency. It’s a great generator for the price.

    + PROS:
    • Love everything about the generator.
    - CONS:
    • None, now that I know I can run the fuel from the carb, between use.
