Best portable generators for home backup
Portable generators with enough continuous output for a practical essential-circuits plan, ranked for fuel flexibility, value, and documented specifications.
Bottom line
For most essential-circuit plans, start in the 5,000–8,000 running-watt range and favor fuel flexibility over the largest peak-watt number.
A portable generator does not need to run every circuit to be valuable during an outage. The useful target is the simultaneous load you actually plan to support, plus the largest motor-starting surge and sensible headroom.
These rankings focus on portable models rather than permanently installed standby systems. Any connection to household wiring needs approved transfer equipment and qualified installation where required.

Size the essential circuits first
Refrigeration, a furnace blower, lights, communications, and a sump or well pump often produce a much more manageable plan than trying to recreate unlimited utility power.
Compare fuel-specific ratings
Dual- and tri-fuel generators commonly make less power on propane or natural gas. Confirm that the rating for the fuel you intend to store still covers the planned load.
Plan the connection and placement
Fuel-burning generators stay outdoors, at least 20 feet from the home according to CPSC guidance, with exhaust directed away. Never backfeed through a receptacle.

Fixed rules, documented inputs.
The page first removes products outside its category, output, fuel, price, sound, or weight boundaries. Eligible models are scored from the displayed specifications and data coverage, then diversified by brand before a second product from the same maker can appear.
Review the full scoring methodologyCommon questions
Before you choose.
What size portable generator is best for home backup?
Many essential-circuit plans fall between 5,000 and 8,000 running watts, but the right number comes from your simultaneous running load, largest startup surge, and headroom.
Can a portable generator power central air conditioning?
Some high-output models can support certain systems, but compressor startup demand, other active loads, transfer equipment, and the exact air-conditioner rating all matter. This is a professional sizing decision.
