Which one can back up a whole house?

The DuroMax. Its 240V output and 50A 14-50R outlet connect to a transfer switch, and 10,500 running watts on gasoline covers a furnace, fridge and well pump. The inverter is 120V only and tops out at 6,000 running watts.

The 7,250-watt inverter, at about 62 dB in an enclosed frame. The DuroMax is rated 74 dB, roughly four times the sound pressure, so neighbors will notice it at night.

Is the inverter worth it for electronics?

Yes. Inverter output is clean enough for laptops, TVs and medical devices. The DuroMax uses a conventional alternator, so plug sensitive gear in through a surge protector or UPS.

Which lasts longer on a tank?

About the same at half load: roughly 8 hours on the DuroMax's 8.3 gallons and 8.5 hours on the inverter's 3.6 gallons. The DuroMax runs about 17 hours at quarter load.

Can one person move either one?

The inverter, at 144.6 lbs with a wheel kit. The DuroMax is 248 lbs, so plan on two people or a ramp.

Is the DuroMax worth about $300 more?

Only if you need 240V and whole-home power. For RV, tailgating or a few circuits, the $999.00 inverter at Home Depot as of November 5, 2026 covers it for less.
