Model 201122The Champion Power Equipment 201122 is a 2500-watt dual fuel inverter generator featuring CO Shield® carbon monoxide auto shutoff system. It is one of the lightest in its class, operating at a quiet 53 dBA from 23 feet, and offers up to 11.5 hours run time on gasoline or up to 34 hours on propane.

Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Champion Power Equipment 201122 is a dual-fuel generator rated at 1850 running watts with 2500 starting watts. That combination targets portable power needs where you want enough headroom for startup surges while still keeping a compact inverter-style package in mind.
Because it is dual-fuel, the 201122 gives you the option to run on more than one fuel source, which can be practical when availability or storage preferences change. Its wattage figures set clear expectations for what it can sustain continuously versus what it can handle briefly at startup.
With 1850 running watts and 2500 starting watts, this generator is built to handle steady loads while also accommodating the extra burst required when certain devices first switch on. The inverter design is paired with a 3 percent THD rating, which speaks directly to power quality for electronics that benefit from cleaner output.
Noise is rated at 53 dBA, a figure that points toward a quieter operating experience in close quarters, especially when compared against louder open-frame designs. On runtime, it is rated for 11.5 hours at 25 percent load, giving a concrete benchmark for lighter-duty use over a long stretch. The generator also lists a 1.1 gallon fuel tank capacity, tying that 25 percent load runtime to a compact onboard fuel supply.
At 39 lbs, the Champion 201122 stays within a weight range that many people can move without specialized handling, which matters when the generator needs to be repositioned around a campsite, driveway, or work area. Its dimensions of 17.3 x 11.5 x 17.7 inches further reinforce a compact footprint, making it easier to stow in a vehicle or tuck into storage when it is not in use.
That combination of sub-40 lb weight and relatively small overall size supports frequent transport and quick setup, especially when the generator is used as a bring-along power source rather than a permanent installation.
Starting is handled through a recoil starting system, keeping operation straightforward and fully manual. The unit includes indicators, which helps with at-a-glance status checks during use, and it also supports automatic voltage regulation, a feature that helps maintain steadier output as loads change.
For expandability, the 201122 is parallel capable, allowing you to scale output by pairing it with another compatible unit. Practical protection features include a spark arrestor and covered outlets, both of which support safer operation and better durability in outdoor conditions. Compliance is listed as CARB, EPA, and ANSI/PGMA G300-2023, and the generator is backed by a 3-year warranty.

These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
