Check price on AmazonHow we calculate it
Runtime = capacity (Wh) × 0.85 ÷ 35 W
For 2 days you need about 1,980 Wh (840 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your chest freezer longer
- A full chest freezer keeps food frozen ~48 hours unopened, so even a small station can run it in shifts.
- Chest freezers are far more efficient than uprights because cold air doesn't spill out.
- In a cold garage the compressor runs less, extending runtime.
