    Can I use a USB cable other than the one that came with PowerCore II 20000?
    Yes, other cables can be used to charge your devices with PowerCore II 20000. However, to ensure compatibility and the best possible performance, we strongly recommend using your device’s original (OEM) cable, a third-party certified (MFI) cable, or the included cable.
    What kind of wall charger should I use to charge PowerCore II 20000?
    You can safely recharge your PowerCore in 5 hours using a quick charge charger. Lower output chargers (such as some phone chargers) will not charge as quickly or reliably.
    What's the output efficiency of PowerCore II 20000?
    PowerCore II 20000's output efficiency is 60%-70%. Approximately 30% to 40% of the battery capacity is unable to be used because of efficiency complications that affect all electronic devices. These include power lost from circuit heat and voltage conversions from the battery, the charging cable and your device.
    Can PowerCore II 20000 charge other devices while it is being charged?
    No, we have disabled this feature due to the detrimental effects it has on the lifespan of portable chargers.
