- Relatively heavy weight of 92.6 pounds
Summary
The Champion Power Equipment 201321 is a Dual-Fuel generator rated for 3,650 running watts with 4,500 starting watts. That combination targets both steady output for ongoing loads and extra headroom for startup surges, while the Dual-Fuel design adds flexibility in how you keep it running.
As a generator from Champion Power Equipment, the 201321 pairs its wattage ratings with an inverter design, shaping it into a power source that emphasizes controlled output rather than raw capacity alone.
Power & Runtime
With 3,650 running watts and 4,500 starting watts, the 201321 is built to handle continuous demand while also covering the brief spike that comes when certain devices kick on. Its inverter output is paired with a THD rating of less than 3 percent, which speaks directly to cleaner power delivery for electronics that benefit from tighter waveform control.
In operation, the generator is rated at 64 dBA, giving you a concrete noise figure to weigh against where and when you plan to run it. For endurance, it lists 22 hours of runtime at 25 percent load, supported by a 4.02-gallon fuel tank, which translates into longer stretches between refueling when you are keeping demand modest.
Portability
At 92.6 lbs, the 201321 is a substantial unit that you will feel when moving it, so its portability is best thought of in terms of deliberate repositioning rather than effortless carrying. Its physical footprint of 20.9 x 18.3 x 19.4 inches helps clarify how much space it will occupy in storage or in a vehicle, and those dimensions also make it easier to plan placement when you need to keep it accessible for operation.
Features
Starting is handled through a recoil system, keeping operation straightforward and fully manual. Day-to-day usability is supported by a fuel gauge and indicators, which help you monitor status at a glance while the generator is running.
The 201321 is parallel capable, allowing you to connect it for scalable output, and it is also RV ready for setups that call for that compatibility. Practical protection and stability features include covered outlets, a spark arrestor, and AVR automatic voltage regulation, while compliance is listed as EPA and ANSI/PGMA G300-2023. Champion Power Equipment backs the unit with a 3-year warranty, adding a defined coverage term to the overall package.

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.
