Fridge back up during power outage

Keeping the Fridge Running When the Power Goes Out

Losing power for a few hours is an inconvenience. Losing a fridge full of food — or insulin, or medication that has to stay cold — is something else. A quiet battery backup sitting behind the fridge takes that worry off the table.

Why we use this at home

We have this backup power in our home with our fridge plugged directly into the Bluetti, then the Bluetti is plugged directly into the wall. It saves us setting up our generator.

When the power drops, the fridge simply keeps running. Nothing to start, nothing to carry outside, nothing to refuel in the dark.

  1. Plug the Bluetti into the wall. It charges and stays topped up.
  2. Plug the fridge into the Bluetti. That's the whole setup.
  3. When the power goes out, the battery takes over automatically — no switch to flip, no generator to start.

The units we'd recommend

All three are the same BLUETTI FridgePower system — the difference is how much stored power comes with it. Start where your budget lands; you can add capacity later.
