DuroMax warranty for generators
The short version
DuroMax covers generators in full for 5 years, with no partial coverage after that. That full coverage is longer than most of the 14 brands we compared, which typically cover 1 year in full. You don't need to register to get this coverage.
From DuroMax's published warranty, checked October 2026.
