Backup power

When the grid goes down, the fridge stays cold.

A dual-fuel generator runs on gasoline or propane, so you are not stuck in a gas-station line after a storm. Plug it into a transfer switch or run cords to what matters most.

  • Gasoline or propane, switch as you go
  • Electric start with a pull-cord backup
  • Transfer-switch ready on larger models

What do you need to keep running?

Tick what you want powered during an outage. We add up the running watts and show the generators that cover it.

Estimates only. Motors such as AC compressors and pumps need extra watts for a few seconds when they start.
