Best use cases

Choose the Champion 201122 if you want a small dual-fuel inverter that is easier to carry and less intrusive to be around. At 39 lb and 53 dB, it is a better fit for camping, tailgating, and overnight use where noise can be the difference between “set it and forget it” and constantly thinking about where to place it. The 11.5-hour runtime at 25% load also helps for long evenings of charging phones, running lights, powering a small fan, or keeping a CPAP going (always confirm your exact CPAP wattage and whether you need a pure sine wave, but inverter models are generally the right direction for sensitive electronics). For light home backup, it is a practical choice for keeping essentials topped up, like a fridge in cycling bursts, modem, and a few lights, as long as you manage starting surges.

Choose the A-iPower SUA2301iD if your priority is similar inverter performance and dual-fuel flexibility, and you do not mind a louder, heavier unit. At 62 dB and 46.2 lb, it is less ideal for quiet campgrounds, but it can still work well for daytime use, occasional emergency charging, or as a compact backup option when you mainly run intermittent loads. Its 1800 running watts and 2300 starting watts are close to Champion’s, so the real-world difference is usually not what it can power, but how pleasant it is to operate and move.

In RV or travel-trailer scenarios, both are best viewed as “small power” options for battery charging and lighter appliances, not a sure bet for running an RV air conditioner. If you need to start and run larger loads, you may need more starting watts than either provides, or plan on soft-start hardware and careful load management.

Verdict & recommendation

If your priority is a quieter generator that is easier to carry and can run longer between refuels, the Champion 201122 is the more comfortable day-to-day companion, especially for camping, tailgating, and neighborhood-friendly use. If your priority is simply getting a dual-fuel inverter in this small-wattage class and you can tolerate more noise and a heavier lift, the A-iPower SUA2301iD can still cover the same general category of light-duty power needs.

Because their wattage is so close, the decision usually comes down to livability: sound level, weight, and runtime. Pick the one that best matches where you will use it and how often you will move it.
