Packaging container and method for charging a stack of electronic devices
A container for an electronic device having a battery and a method of maintaining electrical charge in the battery are described. The container includes a cushioning material, such as molded expanded foam, to receive and secure the device (e.g. for shipping or storage) and to position its battery charging interface near a charging terminal within the container. The charging terminal itself cushions the device, and is electrically connected to charging terminals on the top and bottom of the container, such as a plate on the top and a pogo pin on the bottom. Connecting the charging terminals to a power source supplies power to the charging terminal, hence the battery charging interface of the device either via a physical contact or wireless power transfer. The container and method may be used to deliver the electronic device fully charged to an end user.
