How to choose
Good to know
How long will a portable fridge run on a car battery?
It depends on the fridge’s power consumption and the battery’s capacity. A typical 12V fridge draws about 2 to 5 amps. A 100Ah battery might run it for 20 to 50 hours, but always use low voltage protection.

Yes, many owners leave their fridge running while driving or when connected to a power source. They are designed for continuous operation. In a parked car, ensure the battery is not drained completely.
What is the difference between a cooler and a portable fridge?
A cooler only holds ice and provides passive cooling. A portable fridge uses a compressor to actively cool and maintains a set temperature. It can also freeze items.
Do portable fridges need ice?
No, they do not need ice. They cool using a compressor, so you can set the temperature and the fridge maintains it.
