The PowerSmart MB5040DC is a dual-fuel inverter generator that runs on gasoline or propane. It delivers 3,600 rated watts and 4,400 surge watts on gas, and about 4,000 starting watts on LPG. Inverter output stays under 3% THD, so laptops, phones and TVs are safe to plug in. It has a 223 cc engine, a 1.6-gallon tank and recoil start, and weighs 65 lb. That makes it a portable unit for tailgates, job sites and short outages, not a whole-home standby. Rivals in this class often add electric start or a larger tank; this one leans on dual-fuel flexibility and built-in CO Alert instead. Buyers report easy starting and smooth running on both fuels.

This is a dual-fuel inverter generator that runs on gasoline or propane (LPG). It delivers up to 4,400 starting watts on gasoline and 4,000 starting watts on LPG. The inverter output has less than 3% THD, which suits sensitive electronics.
It runs up to 8 hours at 25% load on gasoline. A 20-lb propane tank gives about 6 hours. A built-in CO Alert monitors carbon monoxide and shuts the unit down automatically. The generator also has overload, short-circuit and low-oil protection.
The control panel has a 120V 30A twist-lock outlet, a 120V 20A household outlet and a 12V 8A DC outlet. It also has an Eco Mode. The housing is made of ABS, and the engine starts with a recoil pull.
