What will a 3,500-watt generator run?

Short answer

A 3,500-watt generator can start any single appliance that needs up to 3,500 starting watts — enough to start common essentials like a refrigerator / freezer, a furnace blower fan, a well pump. Because only one motor surges at a time, you can run several of them together as long as their combined running watts plus the largest single surge stays under 3,500W.

Frequently asked questions

What will a 3,500-watt generator run?

A 3,500-watt generator can start any single appliance needing up to 3,500 starting watts — 41 of the appliances in our database qualify. Because only one motor surges at a time, you can run several together as long as their combined running watts plus the single largest surge stays under 3,500W.

Can a 3,500-watt generator run a house?

It can run a selection of essentials, not an entire house at once. Size it by the specific appliances you need during an outage — typically a refrigerator, some lights, a furnace fan or window AC, and device chargers — rather than by your home's total square footage.

Is 3,500 watts running watts or starting watts?

Generators are advertised by their peak (starting) wattage, so a "3,500W generator" can supply 3,500 starting watts for a brief surge and a lower figure — often 10-20% less — continuously. Size your load against the starting figure to be safe.
