Gas generators (gasoline only) compared in 2026

A gas generator here means gasoline only: no propane kit, no natural gas port, the simplest machine on this site. Below are those portables, plus the wheel kits, tanks and parts sold for them, best-rated first; for a part, hold it against your generator's model number before you order.

Most buyers searching for a gas generator end up with a dual fuel model that also runs on gasoline: see our best dual fuel generators and best propane generators. Gasoline-only units make sense if you already rotate cans for the mower and your outages last a day, not a week.
