How Long Will It Run My Fridge?
This is the #1 question we get. The short answer: a standard fridge averages 60–100W (not the 400W nameplate — the compressor cycles on and off). So:
| Power Station Capacity | Estimated Fridge Runtime |
|---|---|
| 640Wh (Explorer 600 v2) | 6–8 hours |
| 1,070Wh (Explorer 1000 v2) | 10–14 hours |
| 2,042Wh (Explorer 2000 v2) | 20–28 hours |
| 3,600Wh (HomePower 3600 Plus) | 36–48 hours |
| 5,040Wh (Explorer 5000 Plus) | 50+ hours |
