Dual-fuel portable
DuroMax
The short version
Big dual-fuel and tri-fuel wattage per dollar with a 5-year warranty on the HX lines; loud, heavy, and support gets thin after the sale.

Getting the power into the house
Pairs with a $400-$850 interlock install for panel power; the 50A outlet and MX2 full-power switch feed a panel interlock directly.
Service reality: Direct phone and email support from California with sparse authorized service centers; plan on shipped parts and DIY-friendly repairs rather than house calls.
Best for
The wattage-per-dollar buyer backing up a whole panel through an interlock, especially on propane or natural gas with the HXT.
Not for
Anyone who wants quiet, light or hand-holding support; this is job-site iron pointed at a house.
What it does well
- +13kW-class dual-fuel and tri-fuel for under $1,500 on sale
- +5-year residential warranty on HX/HXT lines beats the budget field
- +50A outlet and MX2 switch make whole-panel interlock hookups simple
Where it falls short
Sourced, not our opinion. This is the part the brand's own page leaves off.
BBB shows unanswered complaints (not BBB accredited) and review sites log slow or no response on parts and warranty repairs; complainants note coverage pays for parts, not service calls.

The 13kW class weighs well over 200 pounds and runs far louder than any inverter; fine on a job site, a lot of generator to wheel out and live next to in a week-long outage.
