How do I return my Joos power bank?

Returning is quick and easy:

1. Find any Joos station (doesn't have to be the one you rented from)
2. Press the silver "Return Power Bank" button on the right side of the station
3. A light will flash next to an open slot
4. Insert your power bank with the side containing the cables going in first
5. Make sure the cables are properly tucked in
6. Wait for the green confirmation light to know your return was successful
