Generator Brands

The major US generator brands at a glance — Generac, Kohler, Cummins, Briggs & Stratton, Champion, Westinghouse, Honda, DuroMax, Predator, FIRMAN and WEN — with their standby and portable line-ups, specs and where each one fits.

Generac
The US market leader in home standby — the widest whole-house line-up and dealer network.
Kohler
The main premium alternative to Generac for whole-house standby, known for build quality.
Cummins
The third serious home-standby name, backed by Cummins’ industrial engine heritage.
Champion
A value leader in portable and dual-fuel generators, with a growing standby range.
Westinghouse
A strong portable and dual-fuel choice for home backup, RV and recreation.
Predator
Harbor Freight’s house brand — the budget entry point for portable and inverter generators, sold only through Harbor Freight stores and its website.
DuroMax
A budget-to-mid-range brand built around high running-watt dual-fuel portables — more raw power per dollar than a quiet, compact inverter.
Briggs & Stratton
A home-standby line built around an unusually long warranty — 7 years standard, 10 through a dealer — versus the 5-year norm from Generac, Kohler and Cummins.
Honda
The long-standing quiet-and-reliability benchmark for portable inverter generators — a premium price for class-leading refinement and resale value.
FIRMAN
A value brand built around fuel flexibility — dual-fuel and tri-fuel at prices below the better-known names, sold widely through Lowe’s, Amazon and Costco.
WEN
A budget portable and inverter brand sold through Amazon and general retail — the value alternative for buyers who want a longer warranty than Harbor Freight’s Predator line without paying Honda prices.
