Full listing title: Champion 8500-Watt Remote Start Tri Fuel Portable Inverter Generator
Two generators close to it on our rating, each with a dated price.



What it has going for it
Three fuels. Natural gas from the house line means no refuelling at 2 a.m., and it is also the lowest-output fuel of the three. The hookup is a job for a licensed gas fitter, not a hose and a guess.
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.
Remote start. Start it from the porch with the fob instead of yanking a cord in the rain. Keep the battery charged between storms; the recoil stays as a backup.
The seller states, word for word, in the Champion 8,500W Tri Fuel Inverter listing:
Operates on natural gas, propane, or gasoline, with hoses included for natural gas (25 ft.) and propane (6.6 ft.) so it’s ready to run on any fuel right out of the box.
Connects your generator to Energy Storage Systems or Automatic Transfer Switches, automating start/stop and enabling 120V AC battery charging.
With a run time of 13 hr. and operating at 64 dB(A), this generator delivers reliable power with low noise.
The seller's claims, quoted as written; we haven't measured any of it. The noise on your driveway and the surge of your well pump are things you only find out at home.

Our take
The Champion 8,500W Tri Fuel Inverter earns its place with gasoline, propane and natural gas on one panel and an inverter engine that idles down at light load. No buyer reviews yet, so the Champion 8,500W Tri Fuel Inverter has to win you over on paper. The catch with this Champion inverter generator: no CO sensor in the listing, while most picks here have one. We'd pick it if your house already has a natural gas line; otherwise, put it next to the Champion 10,000W Tri Fuel Open Frame first.
Fill it with oil before the first start, then run it for a few minutes outside with a small load.
Start it with the fob, 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 13 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, then on schedule. Air filter and spark plug once a season, and a cover for the months it sits.
Before the Champion 8,500W Tri Fuel Inverter goes in your cart, check the running watts: the listing we read gives no clear wattage, so ask for the running figure before you size anything against it.
Write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums.
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. 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 Champion 8,500W Tri Fuel Inverter stacks up against the closest alternative, the Champion 10,000W Tri Fuel Open Frame.
| Criterion | Champion 8,500W Tri Fuel Inverter | Champion 10,000W Tri Fuel Open Frame |
|---|---|---|
| Our rating | 7.1/10 | 6.8/10 |
| Start | Remote | Electric |
| Runtime | 13 h | Not stated |
On our rating, the Champion 8,500W Tri Fuel Inverter comes out ahead (7.1 vs 6.8), and it brings remote start and a longer stated runtime (13 h) on top. Start with this one.
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 names gasoline, propane and natural gas. 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 gasoline, propane and natural gas on one panel, clean inverter power, remote start from a key fob, up to 13 hours per tank and a 3-year warranty. 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: write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums. 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. 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.
