Description
Zoom on the Champion 201120
The Champion 201120 replaced the 200994. It's a compact portable inverter generator especially useful for:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating hobbyists looking for a portable power source
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
Thanks to its dual-fuel technology, the Champion 201120 provides a 120V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 3,650W and a starting wattage of 4,650W. Alternatively, when operating on propane, it provides 3,285 running watts and 4,650 starting watts. In addition, as it is parallel capable (ParaLink (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.
Enjoying a noise rating of 61 dBA (just slightly more noisy than an office), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a hassle-free and practical electric starter (battery included). Champion’s EZ Start Dial lets you intuitively start the engine with easy access to all the controls you need.
As for its running time, the 201120, along with its 2.3 gallons fuel capacity, can run for up to 14 hours with a full tank filled with gasoline (fuel consumption around 0.16 GPH). If propane is used, it can operate for up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the 201120 produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel features the following 3 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease. Thanks to the included dual port USB adapter, you can conveniently use the DC receptacle to charge electronics such as mobile phones and tablets.
Thanks to its TT-30R receptacle (TT meaning 'Travel Trailer'), this Champion generator is RV Ready, ready to power your recreational vehicle with ease.
Portability
Thanks to its closed inverter generator design (L23.2 x W17.7 x H20.1 in), the Champion 201120 not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The featured design follows the latest trends and is ideal for easy and recreational use.
As the generator's weight is 103 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, the restricted maneuverability is counteracted by its set of 2 wheels (⌀5") and its folding handle, enabling easy shifting once the generator is set in place.
Features
Enhancing monitoring capabilities, the 201120 features a digital Intelligauge data center within its control panel, furnishing essential details on the lifetime run hours, frequency, power output and voltage for tracking activity and status.
In addition to this info, the device's light indicator will illuminate to indicate if the oil level is too low.
Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.
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.
The unit also benefits from the CO Shield™ technology, which monitors accumulation of poisonous carbon monoxide (CO) gas produced by the engine's exhaust when the generator is running. If CO Shield™ detects elevated levels of CO gas, it automatically shuts off the engine and illuminates a red LED.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Champion 201120 ships with supplementary accessories: oil, dual port USB adapter, tool kit, funnel and propane hose. An official storage cover is also available, as a separate purchase.

The Champion 201120 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Champion 201120 compare to inverter generators of similar power (between 3500 and 4500 W).
- At 103 lbs in dry weight, the Champion 201120 fits well within the typical weight bracket for inverter generators producing 3500 to 4500 rated watts. if you wish to prioritize weight, the WEN 56432iX is one of the top contenders in its power category, weighing only 52.9 pounds.
- At 61 dBA, this inverter generator's noise rating is in line with the expected average for devices within its type and power category. If you wish to prioritize minimal noise, the Westinghouse iGen5000DF stands out as one of the quietest options among generators of similar power, with a rating of 52 dBA.
- As for its autonomy, the 201120, with an autonomy of up to 14 hours at a 25% load, is placed on the low end among the generators of its kind. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Firman WH03662OF, boasting with up to 25 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. Among generators of similar power, this inverter generator stands out with one of the best fuel efficiency, with consumption rates around 0.16 GPH (gallon per hour) at 25% load.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the Champion 201120 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

A couple questions, how is the switching from gasoline to propane, if gasoline is in the tank and a LPG tank is connected and turned on simultaneously, what happens? How do you run the carburetor dry for storage? The fuel and ignition are tied together so when the fuel is shut off the engine stops immediately leaving the bowl full. I purchased this generator and am disappointed these subjects were totally ignored by the manufacturer. Also, apparently no watt or amp gauge just led lights showing % load. (Asked November 18, 2021)
The unit will always try to run on propane first. If there's no propane, it will run on gasoline. To drain the tank and the carburetor, you may refer to the "long term storage" section of your owner's manual.

User Reviews
I would highly recommend this generator for a mechanically challenged user, the controls are extremely simple. Basically one knob controls everything. I honestly purchased this so my wife could fire it up if I wasn’t around but the lack of control and information is frustrating to me.
I’d rather have a separate manual choke and fuel valve starter and kill switch. If this integrated knob breaks your SOL.
I was also disappointed with the lack of any wattage/amperage meter.
On the positive side, I haven’t had any quality of materials or workmanship issues. It’s been 100% dependable and at a excellent price point.
My next portable will have separate controls and a amp monitor of some sort.
I’m also not sure how the switch between gas & propane is handled?
There’s also no way to shut off the gasoline fuel valve to run the carburetor dry because of that all in one switch, you have to open a drain on the carburetor.
But again, reliable!
