the temperature you want. After that, the control panel will display the current inside temperature 
of the cooler. Don’t worry. The display will gradually change until the cooler reaches your desired

treat it like the fridge in your kitchen.

TIP

 below for recharging your battery.

Plug in the AC power cord to a wall outlet. The power button is located on the control panel on top 
of the cooler. Press and hold the power button on the cooler for about 3 seconds. The LED display 
will illuminate. 

Turn ON the LiONCooler. 

TIP:

In order to recharge the battery, the battery must be switched on (yellow light) and the cooler 
plugged into a wall outlet. You only really need to turn the battery ON when you are ‘going mobile’ i.e. 
have no access to a wall outlet OR you need to recharge the battery. Batteries can also be recharged 
when removed from the cooler by using an external power pack (available as a separate accessory 
separately).
