Two generators that are also inverters, of about the same size, closest to it on our rating, each with a dated price.



That's the running figure the listing states, on gasoline. That covers the fridge, lights, the router and phone chargers if you add them up first; central air and a 240 V well pump are beyond it.
What it has going for it
Gasoline or propane. Propane keeps for years in a sealed tank and won't gum up the carburetor between storms; gasoline gives you more watts. Propane is rated lower, so find that figure in the manual.
Inverter, under 3 % THD. The engine speeds up and slows down with the load, so it is quieter and thriftier at 3 a.m. when only the fridge and a lamp are on. The clean sine wave is kinder to laptops, TVs and the furnace control board.
At the campsite: it's an inverter, so the engine idles down at light loads, the listing states 52 dB, it has a TT-30R, the usual camper plug, two can be linked with a parallel kit and it weighs 42 lb, per the listing. Campgrounds set generator hours; look them up before the trip.
On outage night: 1,900 running watts keep the fridge cold and the lights and the Wi-Fi on, with the big draws taking turns. Central air and a 240 V well pump need more.
What the Westinghouse 2,550W Inverter listing names:
Read the manual for the fuel, the oil grade and what each outlet is rated for before the first start.

At the price on Sep 30, 2026, each 1,000 running watts works out at about $278.42 (price ÷ stated running watts, our arithmetic). That puts it in the pricier third of the 33 generators up to 4,000 running watts we have a price and a stated running figure for.
A fuel can and a bottle of stabilizer are extra.

Want a CO shutoff? The Generac 2,500W Inverter (7.1/10) names a CO sensor that shuts the engine off.
Well pump or central air on the list? The Westinghouse 5,000W Dual Fuel Inverter (9.2/10) is rated 3,900 running watts.
Our take
Our favourite thing about the Westinghouse 2,550W Inverter is 1,900 running watts (2,550 at start-up), closely followed by a gas-or-propane fuel switch. No buyer reviews yet, so the Westinghouse 2,550W Inverter has to win you over on paper. The catch with this Westinghouse inverter generator: no electric start in the listing, while most picks here have one. We'd pick the Westinghouse if you need the fridge, lights and phones, not the whole house; otherwise, put it next to the Champion 2,500W Inverter first.
At 42 lb (stated), have a second person or a dolly ready. Fill it with oil (the listing says a bottle comes in the box) before the first start, then run it for a few minutes outside with a small load.
Pull the cord, let it warm up, then add loads one at a time, the biggest motor first. Propane or gas: decide before the storm and have the hose and the tank ready.
Run it every month or so for 20 minutes. On propane you avoid stale gas in the carburetor; on gas, add stabiliser or run it dry before storage. Our maintenance schedule has the full list.
First oil change after the break-in hours in the manual, then on schedule. Air filter and spark plug once a season, and a cover for the months it sits.
Before you order the Westinghouse 2,550W Inverter, check your load list: 1,900 running watts (2,550 at start-up) have to cover everything you run at once, motor surges included.
Read the label on each appliance (or the manual) for its running watts, and note which ones have a motor. Our running vs starting watts guide explains why the motor ones need the extra surge.
Plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes.
Outside only, about 20 ft from doors, windows and vents, exhaust pointing away (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details.
Gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.
How the Westinghouse 2,550W Inverter stacks up against the closest alternative, the Champion 2,500W Inverter.
| Criterion | Westinghouse 2,550W Inverter | Champion 2,500W Inverter |
|---|---|---|
| Our rating | 7.1/10 | 7.1/10 |
| Running watts | 1,900 W | 1,850 W |
| Peak watts | 2,550 W | 2,500 W |
| Fuels | Gas, propane | Not stated |
| Runtime | Not stated | 11.5 h |
Both score 7.1/10. The Champion 2,500W Inverter adds a longer stated runtime (11.5 h), while the Westinghouse 2,550W Inverter brings more running watts (1,900 W) and a higher peak (2,550 W).
We rate it 7.1/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
The listing or manual states 1,900 W running and 2,550 W peak, usually for gasoline. Size your load list against the running watts and keep the peak for motor starts; propane and natural gas ratings are lower. These are the seller's figures, not our measurements (our sizing calculator turns your loads into a running and peak pair).
The listing names gasoline and propane. Output differs by fuel, so check the per-fuel running watts in the manual and whether the hoses you need come in the box. Run it outdoors only, away from doors, windows and vents.
Its listing states 1,900 running watts (2,550 at start-up), the choice of gasoline or propane, inverter power under 3 % THD, a built-in CO sensor, a stated 52 dB and parallel capability. These are the seller's figures, not our measurements: how loud it is in your driveway and how it handles your well pump's surge can't be read from a listing.
Your load list: read the label on each appliance (or the manual) for its running watts, and note which ones have a motor. Our running vs starting watts guide explains why the motor ones need the extra surge. How it reaches the house: plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes. Where it will run: outside only, about 20 ft from doors, windows and vents, exhaust pointing away (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details. Fuel for three days: gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.
