Buy — 9,500 W gas / 8,500 W propane continuous dual-fuel with L14-30 + 14-50; open-frame ~74 dBA, THD ≤23%, no CO sensor, not CARB

For homeowners who need about 9,500 W continuous on gasoline (or 8,500 W on propane) with a factory 14-50R and L14-30R transfer path — not a quiet inverter, and not the live Westinghouse iGen4500c / iGen5000c suitcase class.

Exact marketing name WGen9500DF on Westinghouse.com (UPC 853544008298). Open-frame dual-fuel portable, not the quiet iGen inverters, and not Champion 201281 (7,500 W class with CO Shield).

What it is

A conventional (non-inverter) dual-fuel portable: 457 cc OHV 4-stroke Westinghouse engine with cast-iron sleeve, 6.6 gal gasoline tank, bonded-neutral grounding, VFT meter, automatic low-oil shutdown, overload protection, never-flat wheels, and lift bracket. Start: push-button electric + remote key fob + recoil; battery included. Fuel switches gas ↔ propane without shutting off.

Manufacturer continuous / peak (US product page, checked 16 Oct 2026): gasoline 9,500 W running / 12,500 W peak; propane 8,500 W running / 11,200 W peak. Voltage 120/240 V, 60 Hz. Outlets: (2) GFCI 5-20R duplex, (1) L14-30R 120/240 transfer-ready, (1) 14-50R ST Switch ready. Noise as low as 74 dBA. Dry weight 211 lb (older sheet said 220 lb — trust product page). Dimensions 27.2 × 26.1 × 26.5 in. Runtime claims: up to 12 h @ 25% gas, 8 h @ 50% gas; up to 7 h on a 20 lb propane tank @ 50%. THD ≤23% (not inverter-clean). CO sensor: No. CARB Compliant: No on the current listing (older sheet claimed EPA/CARB — do not cite CARB from the PDF). Warranty: 3-year residential / 1-year commercial. Manufacturer MSRP on product page: $1,249.00 (checked 16 Oct 2026). Links: no affiliate.

What it will actually run

Running watts first: 9,500 W gasoline continuous / 8,500 W propane continuous. Surge second: 12,500 W gas / 11,200 W propane peak.

Will run

Fridge/freezer plus furnace blower, sump, modem/router, and selective 240 V loads on a sized L14-30 or 14-50 transfer / interlock path
A dryer or similar high draw when other legs are managed
RV 50 A service via the 14-50R when cord and inlet match

Skip, or measure first

Sensitive electronics on raw generator power — THD ≤23% is not clean; use a true online double-conversion UPS or skip
Whole-home automatic standby without a transfer device
CARB-only jurisdictions — current listing is not CARB
One-hand carry — ~211 lb dry

Specs that matter

Continuous first: 9,500 W gas / 8,500 W propane @ 120/240 V
Peak / surge: 12,500 W gas / 11,200 W propane; not continuous
Fuel: dual-fuel (gasoline / LPG); 6.6 gal gas tank; switch without shutdown
Runtime claim: 12 h @ 25% / 8 h @ 50% gas; 7 h on 20 lb propane @ 50%
Weight: 211 lb dry (product page)
Outlets: (2) GFCI 5-20R duplex, L14-30R, 14-50R ST Switch ready
Start: electric + remote + recoil; battery included
THD ≤23%; no CO sensor; not CARB on current US listing

Who should skip it

You need inverter-clean power for unprotected electronics — look at Westinghouse iGen4500c / iGen5000c.
You need a CO sensor on the plate — current WGen9500DF listing has none; Champion 201281 peers with CO Shield.
You need CARB compliance for your state — current product page says No.
You believed “12,500 watt” meant 12,500 W all night — that is peak, not continuous.
You need under ~100 lb or a quiet suitcase — this is open-frame ~74 dBA.

Verdict

Buy when the job is honest ~9.5 kW gasoline / ~8.5 kW propane continuous backup with factory L14-30 and 14-50 transfer paths, dual-fuel logistics, and e-start/remote — and you accept open-frame noise, dirty THD, no CO sensor, and not-CARB on the current US listing. Not an inverter. Not the iGen suitcase line. If the nameplate is not WGen9500DF, leave this page.
