The two picks next to it in our dual fuel inverter generators ranking, with their rating and a dated price.



That's the running figure the listing states, on gasoline. Room for the fridge, a few lamps, the router and the phones, as long as the coffee maker waits its turn. Central air and a 240 V well pump are out of its league.
Why it made our list
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. 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 61 dB and two can be linked with a parallel kit, per the listing. Campgrounds set generator hours; look them up before the trip.
On outage night: with 3,500 running watts, the Champion 4,500W Dual Fuel Inverter handles the fridge, a few lamps and the chargers. Anything on a 240 V breaker is a job for a bigger unit.
What the Champion 4,500W Dual Fuel Inverter listing names:
Warranty & support: A 3-year warranty, as stated in the listing.
That is the maker's promise, not ours. Keep the order confirmation, and register the Champion 4,500W Dual Fuel Inverter if the maker asks you to.
The manual for the Champion 4,500W Dual Fuel Inverter has the final word on fuel, oil and outlet ratings.

At the price on Sep 30, 2026, each 1,000 running watts works out at about $257.89 (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.
Count oil for the first fill, a fuel can and stabilizer in the budget too.

Planning an inlet box and a transfer switch? The A-iPower 5,000W Gas & Propane (7.3/10) has an L14-30R outlet.
Well pump or central air on the list? The Champion 8,500W Dual Fuel Inverter (7.8/10) is rated 7,000 running watts.
Neighbours close by? The Westinghouse 5,000W Dual Fuel Inverter (9.2/10) states 52 dB.
Our take
We like the Champion 4,500W Dual Fuel Inverter for 3,500 running and 4,500 peak watts and the choice of gasoline or propane. 398 buyers have had their say, which is plenty to go on. Honestly, the catch: their 4.4/5 average sits under the 4.6 of this ranking. We'd pick it if you need the fridge, lights and phones, not the whole house; otherwise, put it next to the Westinghouse 5,000W Dual Fuel Inverter first.
Fill it with oil before the first start, then run it for a few minutes outside with a small load.
Push the start button, 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. The 14 hours on the listing are at a light load; plan a refill at night.
Run it every month or so for 20 minutes and keep the battery charged. 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 (the hour meter counts them), then on schedule. Air filter and spark plug once a season, and a cover for the months it sits.
Buyers give it 4.4/5, a strong record, slightly below this ranking's 4.6 average. And with 398 reviews behind it, that number is hard to argue with.
Before you order the Champion 4,500W Dual Fuel Inverter, check your load list: 3,500 running watts (4,500 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.

Pick the Westinghouse 5,000W Dual Fuel Inverter if you want our higher-rated option (9.2/10), with more running watts (3,900 W) and a higher peak (5,000 W); stay with the Champion 4,500W Dual Fuel Inverter for a CO sensor.
We rate it 7.3/10 (good), #2 of 5 in our dual fuel inverter generator ranking. It is based on 398 buyer reviews averaging 4.4/5 and the specifications stated in the listing.
The listing or manual states 3,500 W running and 4,500 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 3,500 running watts (4,500 at start-up), the choice of gasoline or propane, clean inverter power, a built-in CO sensor, push-button electric start and up to 14 hours per tank. 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.
