Stack / 201175
Updated · 29 Oct 2026 · Sheet checked · 29 Oct 2026
Buy — 7,000 W gas / 6,300 W propane running, 8,500 W starting, 120/240 V enclosed inverter; L14-30R and 14-50R, 29.2 A running at 240 V; electric start, CO Shield; 213.9 lb, neutral bonded to frame
For a house that needs 240 V through a listed 30 A transfer switch, on gasoline or propane: 7,000 W running on gasoline, 6,300 W on propane. The 8,500 W in the name is starting watts.
Exact model 201175 (8500W Electric Start Dual Fuel Inverter), not the live open-frame Champion 201281.
Enclosed inverter on wheels; Champion 420 cc OHV engine, variable speed. Electric start (included 12 V, 9 Ah lead-acid battery) with recoil backup; the EZ Start dial selects fuel.
Fuel: gasoline (87 octane minimum, E10 or less) in a 5.33 gal tank, or a 20-lb propane cylinder.
Outlets: two 120 V 5-20R GFCI duplexes (20 A), one 120/240 V L14-30R, one 120/240 V 14-50R, and a 12 V DC outlet. The 29.2 A Champion lists on both 240 V outlets is the generator's rated running current at 240 V on gasoline (26.3 A propane), not the receptacle rating. The 14-50R is a 50 A receptacle shape, not 50 A of supply.
CO Shield shuts the engine down when carbon monoxide builds up; it does not replace a CO alarm. Low-oil shutoff, covered outlets. EPA certified; no CARB claim on Champion's page.
Manual: 213.9 lb (97.0 kg), 33.4 × 29.1 × 26.0 in. Noise: Champion's page lists 64 dBA at 23 ft; the sell sheet says 61 dBA. Plan from 64. Warranty is 3 years.
Grounding: the manual says neutral bonded to frame. Champion requires a listed 30 A transfer switch installed by a licensed electrician; have them settle the neutral-ground bond before wiring.
Parallel: Champion's spec table says No; the sell sheet mentions a parallel kit. Plan on No.
Price: not published on Champion's product page, checked 29 Oct 2026. Links: no affiliate.
Running watts first: 7,000 W gasoline, 6,300 W propane. Surge second: 8,500 W, motor starts only. Each 120 V leg carries half, about 3,500 W per leg on gasoline (Outage Stack math); balance 120 V loads or one breaker trips first.
At Champion's 25% load (about 1,750 W gasoline, Outage Stack math): 14 h per 5.33 gal tank or 12 h per 20-lb propane tank. A 72-hour outage at quarter load needs about 27 gal of gasoline or six 20-lb tanks (Outage Stack math).
Per Outage Stack's size table:
Buy. 7,000 W running at 120/240 V from an enclosed inverter, either fuel, electric start, CO shutoff, 64 dBA: enough for a 240 V well pump, fridge, and furnace through a listed 30 A transfer switch. Plan from 7,000 W gasoline / 6,300 W propane, never 8,500 W. Settle the bonded neutral with your electrician.
