The DJI Osmo Pocket Charging Case is a portable power bank for the Osmo Pocket Gimbal, allowing you to charge the gimbal on the go. What's special about it is that instead of connecting to the gimbal via a cable, like power banks normally do, it's designed for you to neatly place the gimbal inside of it, like you would a battery into a battery slot. The case provides 1500mAh of charging power, and it's rechargeable via a USB port when it's out of power. It requires an optional micro-USB Type-B cable for charging, the kind used to charge most smartphones.
