The DJI Charging Case for Osmo Pocket is a portable power bank designed to charge your Osmo Pocket gimbal on the go. Unlike traditional power banks that require a cable connection, this case allows you to place the gimbal inside it, similar to inserting a battery into a slot. The case provides 1500mAh of charging power and can be recharged via a USB port when it runs out of power. An optional micro-USB Type-B cable is required for recharging the case. This compact and convenient solution ensures your gimbal stays powered while traveling or shooting.
