Anker EverFrost Powered Cooler can be recharged with or without the battery connected. We do not recommend using multiple charging methods at the same time.

Without the battery connected, the Cooler can be recharged through the Cooler’s input port with the supplied 95W AC power adapter via a wall outlet or with the supplied car charging cable via a running car.
 

With the battery connected, there are four recharging methods as listed below:

• Connect the supplied 95W AC power adapter to the Cooler’s input port via a wall outlet.
• Connect the supplied car charging cable to the Cooler’s input port via a running car.
• Connect an 11-30V solar panel with an XT-60 female connector to the battery’s XT-60 input port (refer to the picture below).
• Connect a USB-C PD charger to the battery’s USB-C input/output port  (refer to the picture below).
