You can also charge your tablet or smartphone* with the convenient USB-C port on the case. Double the great times, and enjoy the peace of mind that comes with an official JBL battery. It also can replace the rechargeable battery inside a JBL Xtreme 4 portable speaker and more when it starts to degrade. (*charging cable not included)
