Best Portable Generators for DIYers

A portable generator keeps the fridge cold and the sump running through an outage. Inverter models are quiet and clean for electronics; dual-fuel adds propane flexibility; size it to the watts you must run.

What to look for

  • ·Add up the running and starting watts of what you must power (fridge, sump, furnace fan) and buy 20 to 30% more headroom.
  • ·Inverter generators are quiet and produce clean power safe for electronics; dual-fuel models run on gas or propane for flexibility.
  • ·Never run a generator indoors or in a garage. Use it outside, away from windows, with a transfer switch or interlock for home circuits.

Frequently asked

What size generator do I need for my house?+

Add up the running watts of essentials (fridge ~700W, sump ~800W, furnace fan ~600W, lights and electronics) plus the surge watts of motors that start. Most homes get by on a 5,000 to 9,500 watt unit for essentials; whole-home backup needs more and a transfer switch.

Inverter or conventional generator?+

Inverter generators produce cleaner, more stable power that is safe for sensitive electronics, and they run quieter and more efficiently. Conventional generators are cheaper per watt and fine for tools, pumps, and basic backup. For home backup with electronics, inverter is the safer pick.

What is a dual-fuel generator?+

Dual-fuel units run on gasoline or propane. Propane stores indefinitely and burns cleaner, while gas is easy to find and gives a bit more power. The flexibility is valuable in an extended outage when one fuel runs short.

How do I connect a generator to my house safely?+

Use a transfer switch or an interlock kit installed by an electrician, never a suicide cord into an outlet, which can backfeed and kill a lineman. Run the generator outdoors, far from windows, to keep deadly carbon monoxide out.

How long can a portable generator run?+

Most run 8 to 12 hours on a tank at half load, and inverter and propane setups can stretch longer in eco mode. Plan fuel storage accordingly, and let the unit cool before refueling.
