Check price on AmazonHow we calculate it
Runtime = capacity (Wh) × 0.85 ÷ 18 W
For a weekend trip you need about 1,020 Wh (432 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your 12V fridge longer
- A 12 V compressor fridge averages only 15–25 W in mild weather, about half of a 120 V mini fridge.
- Plug it into the 12 V car outlet, not the AC outlet, to skip inverter losses (5–15% more runtime).
- Pre-cool it at home and keep it in the shade: in hot weather consumption can double.
