Stack / iGen2500c
Updated · 23 Oct 2026 · Sheet checked · 23 Oct 2026
It depends — 1,800 W rated (manual table; 15 A breaker), label 2,200 W running / 2,500 W peak, 120 V only, one 5-20R duplex, recoil start, gas only; about 46 lb
For a light 120 V gasoline inverter that keeps a fridge, a gas-furnace blower, and network gear going, and that one person can carry: 1,800 W rated in the manual's table. The label's 2,200 W running and 2,500 W peak are higher.
Exact model iGen2500c, the version with the CO sensor. Not the older iGen2500 (no "c", no CO sensor), not the iGen2550c that Westinghouse sells now, and not the live Westinghouse iGen4500c. Discontinued: Westinghouse's store no longer lists it.
Suitcase inverter generator. Westinghouse 80 cc engine, manual choke, recoil start only. Gasoline only: unleaded 87–93 octane, up to E10. The manual lists a 1.14 gal (4.3 L) tank. A retailer spec table lists 0.98 gal; plan from the smaller number.
Outlets: one 120 V 5-20R duplex (15 A breaker) and two 5 V 2.1 A USB-A. No 30 A outlet, no TT-30R, no 240 V. Floating neutral, THD 3% or less, low-oil shutdown, overload reset. Parallel outlets on the panel take Westinghouse's parallel cord, part 260041, sold separately.
The CO sensor shuts the engine down when carbon monoxide builds up and shows a red light. Westinghouse says it does not replace a CO alarm in the house. EPA and CARB compliant.
Weight and noise are not in the owner's manual. A retailer spec table lists 46.3 lb dry, 52 dBA, 19.8 × 11.4 × 17.9 in, and a 3-year limited warranty. Those are retailer numbers, not a Westinghouse sheet.
Price: not published. On 26 Oct 2026 Westinghouse's store no longer lists the iGen2500c; the old product URL now returns 404. Links: no affiliate.
Running watts first: 1,800 W rated (manual table, PF 1.0; AC breaker trips above 15 A). The label says 2,200 W running. Surge second: 2,500 W peak (manual table 2.2 kVA), for motor starts only. Plan from 1,800 W continuous for an all-night load. The manual also derates about 3.5% per 1,000 ft of altitude.
Fuel: the retailer table lists 10 h at 25% load. A 72-hour outage at quarter load is about 7–8 gal of gasoline (Outage Stack math).
Using Outage Stack's size table ranges:
It depends. It suits a 120 V fridge, furnace blower, and network stack, carried by one person and run outdoors, with a CO shutoff as backup to a house alarm. It does not cover 240 V, an RV cord, or a window AC start without measuring. Plan from 1,800 W, not 2,200 W, and never from 2,500 W.
