Runtime = capacity (Wh) × 0.85 ÷ 30 W
For a full day you need about 850 Wh (720 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your mini fridge longer
- Mini fridges are less efficient per liter than full-size fridges but use less total energy.
- For camping, a 12 V compressor cooler uses about half the energy of a 120 V mini fridge.
- Keep it out of direct sun and leave space around the coils.
