Champion 201531 — 3,250 W running
Updated · 16 Sep 2026 · Sheet checked · 16 Sep 2026
It depends
Useful number: 3,250 W on gas, 2,925 W on propane. The 4,500 W in the retail title is starting watts.
Will run
Fridge + lights with room. Microwave or a modest window AC — pick one. Longer hold on a 20 lb bottle at 2,925 W.
Skip or measure first
Unmeasured well/sump start. 240 V interlock. Quiet-camp duty if 64 dBA bothers you.
Verdict
Buy when you want more headroom than an EU2200i and a propane hose in the same handle. Do not buy because the box says 4500.
