The special thing about this is that, instead of connecting to the gimbal through a cable, as energy banks usually do, it is designed for you to place the gimbal inside it, as if it were a battery in a battery slot. The case provides 1500 mAh of charging power and is rechargeable through a USB port when it is out of power. Requires an optional Type-B micro-USB cable to charge, the type used to charge most smartphones. The compact case also serves as a storage solution after you have finished loading the cardan so that the two occupy less space in your bag. Not only contains the gimbal but also two microSD cards, four ND filters and two adapters for smartphones. The case has a rotating design to open that allows you to use it conveniently and efficiently.
