Detailed Review

The listing states 11,500 starting watts and 9,200 running watts on gasoline, 10,600 starting watts and 8,500 running watts on LPG, and 8,500 starting watts and 6,800 running watts on natural gas, with remote start, dual 30A outlets, a 50A outlet and a 20A GFCI duplex outlet.

A tri-fuel portable generator with electric start that runs on natural gas, propane or gasoline.

Check price on Amazon

Pros

• 8125 starting watts and 6500 running watts on gasoline
• Natural gas and propane hoses included
• Electric start with a rocker switch
• Engine oil included

Cons

• 197.0 pounds, so it needs its wheels for moving

Where the points went

The Solar Score weighs performance, build, value, safety and warranty. Safety here means stated carbon monoxide protection and outlet protection: the generators state carbon monoxide protection or a carbon monoxide auto shutoff, and the hoses state CSA certification with solid brass fittings. All four picks state a warranty, from a 30-day limited warranty on the hoses to a 2-year warranty on the AIVOLT and a 3-year limited warranty on the Champion. How we pick explains the weights.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

How to choose the best tri fuel generator natural gas

Match watts to the load, fuel by fuel

The headline watts change with the fuel. The AIVOLT lists 11,500 starting watts and 9,200 running watts on gasoline, 10,600 starting watts and 8,500 running watts on LPG, and 8,500 starting watts and 6,800 running watts on natural gas. The Champion lists 8125 starting watts and 6500 running watts on gasoline, 7500 starting watts and 6000 running watts on propane, and 6875 starting watts and 5500 running watts on natural gas. Check the fuel you plan to run before comparing generators, since the natural gas figures sit below the gasoline figures on each unit. The AIVOLT lists a 50A outlet, and a licensed electrician should install any home-wiring connection. For background on the watt figures, see our continuous and surge watts guide.

Check run time and noise at the stated load

Only the AIVOLT states a run time and a noise level. Its 7.1-gallon fuel tank supports up to 16 hours of runtime at 25% load, and the enclosed inverter design operates at approximately 64 dBA at 23 feet at 25% load. The listing notes that runtime varies with load, fuel quality and operating conditions. The Champion states no run time and no noise level, so a buyer who needs those figures should weigh that gap. For home backup use, see our inverter generator for home backup guide.

Weigh the kit, not just the generator

The AIVOLT kit includes a 15-foot natural gas hose, an LPG hose with regulator, a remote control fob, an owner’s manual, a quick start guide, a 12V DC battery charging cable, an oil funnel, a spark plug wrench and a screwdriver, while engine oil is not included. The Champion includes natural gas and propane hoses and engine oil. The Westinghouse hoses are sold on their own for Westinghouse tri fuel generators, so a buyer who owns a different brand should check fit before buying. Remote start on the AIVOLT means the generator can be started without walking out to it, with push-button and recoil backup options.

Size the hose to the generator and the distance

The Westinghouse hoses differ mainly in length and in the rating they state. The 25-foot hose fits Westinghouse tri fuel generators rated under 14500 running watts, and the 15-foot hose fits Westinghouse tri fuel generators rated under 14,500 running watts. Both state CSA certification, reinforced layers and solid brass fittings, and both include a quick connect adaptor that stays on the generator gas intake valve. Measure the distance from the gas supply to the outdoor spot for the generator before choosing a length. For a longer hose option, see our long propane hose for generator guide.

Sizing Notes

• Match the watts to the loads you plan, fuel by fuel: gasoline, LPG and natural gas figures differ on each generator.
• Match the hose length to the distance from the gas supply to the outdoor spot for the generator: 15 feet or 25 feet here.
• Match the hose rating to the generator: the 25-foot hose is rated for generators under 14500 running watts, and the 15-foot hose for generators under 14,500 running watts.
• Match the outlets to the loads: the AIVOLT lists dual 30A outlets, a 50A outlet, a 20A GFCI duplex outlet and 12V DC power.
• Check the stated warranty term: 30-day limited on the hoses, 2-year on the AIVOLT and 3-year limited on the Champion.

FAQ: power away from the grid

Which generator here lists the most starting watts on gasoline?

The AIVOLT lists 11,500 starting watts on gasoline, against 8125 starting watts for the Champion. On natural gas the figures are 8,500 starting watts for the AIVOLT and 6875 starting watts for the Champion.

Do the generators run on natural gas straight out of the box?

The AIVOLT kit includes a 15-foot natural gas hose, and the Champion includes natural gas and propane hoses, so each unit is ready to run on natural gas with its included hose.

Can the Westinghouse hoses fit any tri-fuel generator?

No. The listings state they fit Westinghouse tri fuel generators rated under 14500 running watts for the 25-foot hose and under 14,500 running watts for the 15-foot hose.

Which pick states a noise level?

Only the AIVOLT states one: approximately 64 dBA at 23 feet at 25% load. The Champion states no noise level.

What warranty does each pick state?

The AIVOLT states a 2-year warranty, the Champion states a 3-year limited warranty, and each Westinghouse hose states a 30-day limited warranty.
