It depends — 3,000 W gas / 2,700 W propane running, 4,000 W surge; 120 V only, recoil start; live 201531 gives 3,250 W at the same 51.8 lb

INVERTER

For a one-handle, 120 V dual-fuel inverter that holds a fridge, lights, network gear, and one window AC or microwave through an outage: 3,000 W running on gasoline, 2,700 W on propane. The 4,000 W in the name is starting watts.

Exact model 201050 (Champion 4000W Dual Fuel Inverter). Not the live Champion 201531, which is a different 4,500 W-peak SKU, and not any wheeled or electric-start Champion. If the data plate does not say 201050, this page does not apply.

What it is

Enclosed inverter generator. 149 cc 4-stroke OHV Champion engine, variable speed with Economy Mode. Gasoline from a 1.54 gal tank, or propane through the included regulator hose. Recoil start only; no battery, no remote.

Outlets: one TT-30R (120 V, 25 A), one 5-20R duplex (120 V, 20 A), one 12 V DC socket, and parallel ports. No GFCI. Champion lists under 3% THD. Neutral is floating (manual p. 31); the manual says ask an electrician about grounding (p. 19).

51.8 lb, 17.9 × 11.7 × 19.7 in, no wheels. 64 dBA at 23 ft. CO Shield auto-shutoff. EPA certified; the Champion page does not claim CARB. 3-year limited warranty.

Price: not published on the Champion product page on 20 Oct 2026. Links: no affiliate.

What it will actually run

Running watts first: 3,000 W gasoline (25 A), 2,700 W propane (22.5 A). Surge second: 4,000 W on either fuel (33.3 A), for motor starts only.

Fuel, from Champion's quarter-load claims (750 W gas, 675 W propane): 10 h per 1.54 gal tank, about 0.15 gal/h; 25 h per 20 lb cylinder. A 72-hour ice storm at that light load is about 11 gal of gasoline or three 20 lb cylinders (Outage Stack math from Champion's 1/4-load claims). Heavier loads burn faster; Champion publishes no half-load figure.

Using Outage Stack's size table ranges:

Will run

  • A fridge (150–400 W running) plus lights, phones, modem, router, and a CPAP with room left
  • Fridge plus one 8–10k BTU window AC (800–1,200 W running, 1,800–3,000 W start) fits on paper; start the AC first
  • A microwave (1,000–1,500 W) in place of the AC, not with it
  • An RV shore cord via the TT-30R, 25 A available, one big load at a time

Skip, or measure first

  • A 1/2–3/4 HP well pump (2,000–4,000 W start) until you clamp-meter it
  • Anything 240 V
  • Fridge, window AC, and microwave together (up to 3,100 W running on those ranges, past the gas rating and further past 2,700 W on propane)
  • Champion's manual derates output about 3.5% per 1,000 ft above sea level (p. 26)

Parallel: an optional Champion kit links it to another Parallel Ready Champion unit; no combined running-watt figure is published on the 201050 page.

Specs that matter

Who should skip it

Verdict

It depends. Buy it when the job is a 120 V fridge, network, and lights plus one window AC or microwave, you want propane for shelf-stable fuel, and you will carry 51.8 lb. Skip it when you need 240 V or electric start, or when the 201531 costs the same: that unit adds 250 running watts at the same weight. Plan from 2,700 W if propane is your storm fuel, not from 4,000 W.
