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 buffs looking to enhance their experience
- Amateur DIY lovers
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's design includes a gasoline-fueled 79 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 1,850W and also a peak wattage of 2,500W. Moreover, since it is parallel capable (parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second 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 conversation at home).
With a full tank, the 100889 can operate for up to 11.5 hours (fuel consumption around 0.1 GPH), thanks to its fuel capacity of 1.1 gallon.
Sensitive electronics can be safely plugged in the AC outlets, as the 100889 produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
The control panel features the following 2 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries. 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.
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. This modern design aims to provide an ideal power solution to recreational users.
Labeled a lightweight portable generator, the 100889 weighs just 39.5 lbs. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. This convenience is further enhanced thanks to its handle (molded in the case) that allows you to carry it with ease.
Some light indicators allow you to instantly see if its oil levels are insufficient, the generator is overloaded and the generator is ready.
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 an overload protection (circuit breaker).
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: oil, battery charging cables, funnel and dual port USB adapter. The official storage cover and running cover are also available, as separate purchases.
The Champion 100889 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, making it usable in forested areas.
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).
- Regarding its weight, the Champion 100889 only weighs in at 39.5 pounds, which means it's one of the lighter inverter generators in the 1500-2500 rated wattage range. If weight matters to you, one of the champions in this power range is the Genmax GM2000i with only 34.2 pounds.
- Since this inverter generator is rated for a lowest possible noise of 53 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 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.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. At an estimated fuel consumption of 0.1 GPH (gallon per hour) at 25% load, this inverter generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the DuroMax XP2300iH is a device you could look out for.
As you can see from this interactive chart, 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.

Can I use the 50 amp rv outlet on the parallel kit with two 2500 watt champion inverter generator? (Asked June 30, 2020)
Absolutely, you just won't be able to draw 50 amp out of it.
Couldn't find the right answer for you? Ask your own question.
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.
This 2500w Champion runs my 13.5k RV AC without an issue. It is noticeably lighter than other generators of a similar size.
