The answer assumes an average consumption of 10Wh. Can be realistic if the environment is not too warm and the cooling capacity is not too high.

Dear Nuh,

It all depends on how many watts of power per hour (Wh) this cooler box uses.

If your cooler draws 57.6 Wh, for example, then the EcoFlow will last for a good 10 hours. So you have to ask yourself how long you want to keep the cooler in a cool state and then conclude how many Wh of power you ultimately need and buy the right battery.

Greetings
