Portable Generators
Portable generators for RVs, job sites and home backup from Westinghouse, Champion, WEN, DEWALT and Generac. The range covers quiet inverter generators, dual fuel models that run on gasoline or propane, and tri fuel models that add natural gas, from 1,500 to 12,000 peak watts.
Size a generator to the starting watts of your largest load, usually an air conditioner or well pump, then add what else runs at the same time. Inverter generators are quieter, lighter and make cleaner power for electronics; open-frame portables give more watts for the money. For an RV, look for a TT-30R or 14-50R outlet so the shore cord plugs straight in.
Cords, covers and adapters are on the generators and accessories page. Prefer silent, fuel-free power? See solar generators and portable power stations. Orders ship from Upland, California, with free 30-day returns on a prepaid label.

What size generator do I need?
List what must run together, add the running watts, then add the largest starting surge. A generator whose running rating covers the total and whose peak rating covers the surge is the right size. Check each appliance's data plate for its actual figures.
Inverter generator or conventional portable?
An inverter generator varies engine speed with load, so it is quieter, uses less fuel at light loads and produces cleaner power for electronics. A conventional open-frame generator costs less per watt and suits tools and large loads.
Is dual fuel worth it?
Dual fuel lets you run on gasoline or propane. Propane stores for years and burns cleaner, with slightly lower output than gasoline. See watts lost on propane.
Can a portable generator power a house?
Yes, through a transfer switch or interlock installed by a licensed electrician. Never plug a generator into a wall outlet; backfeeding endangers utility workers and your equipment.
Where is it safe to run a generator?
Outdoors only, well away from doors, windows and vents, with the exhaust pointed away from people. Engine exhaust contains carbon monoxide. Never run one in an RV, garage or enclosed space.
