    Trash- stops charging at 40%, stopped working after 2 weeks. Doubtful of the claimed capacity as these types of batteries usually mislead and exaggerate capacity. Best Buy return policy SUCKS, so now gotta deal with manufacturers warranty.

    Every device I've connected has refused to charge on it or had an allert for the current it provides. It may just be my powerbank, but it could damage your device.
