Frequent Questions

  • powerstation
    Will the powerstation external battery charge my smartphone?
    mophie powerstation 5X and 8X external batteries are compatible with virtually any available smartphone. For example, the powerstation 5X battery can provide up to 5X extra battery to an iPhone 6s, and the powerstation 8X battery can provide up to 8X extra battery to an iPhone 6s.
    Can I charge my tablet from the powerstation battery?
    These powerstation batteries are capable of fully charging virtually any tablet. In fact, the powerstation 8X battery can charge an iPad Air up to two times; the powerstation 5X battery can charge an iPad Air once and still have some juice left.
    Which port is used for charging my device, and which port is for recharging the powerstation battery?
    Connect the supplied USB cable (or the USB cable that came with your device) to one of the two large, rectangular USB ports to charge your device. When you need to recharge the powerstation battery, connect the supplied USB cable to the smaller micro USB port and to any high-current power source with a USB out.
    Once I connect my device to the powerstation battery, how do I start charging?
    Charging begins automatically as soon as you connect your device to the powerstation battery’s USB port.
    One of the powerstation battery’s USB ports is marked with a lightning bolt icon. What does it mean?
    The icon indicates the USB port with 15W Fast Charge capability. Devices that have Qualcomm® Quick Charge™ 2.0 capability or Samsung Adaptive Fast Charging will charge up to 75% faster from this powerstation battery USB port than they will from a typical smartphone charger.
    Can I recharge the powerstation battery from a computer’s USB port?
    Yes, the powerstation battery will recharge from any high-current USB port—which are available on most computers. Lower-current ports available on some computers, as well as USB ports on keyboards and hubs, may not effectively recharge the powerstation battery.
    Can I charge my device while recharging the powerstation battery (Priority+ charging)?
    The powerstation 5X and 8X batteries have Priority+ pass-through charging, so while you’re recharging the powerstation battery you can also charge a device connected to its USB port marked with the Priority+ Charging icon (battery with arrows) — your connected device charges first, then the powerstation battery recharges. Note that although these powerstation batteries can charge two devices simultaneously, they can only charge one device while they are being recharged.
    Why aren’t the LEDs blinking while my powerstation battery is recharging?
    After connecting the powerstation battery’s micro USB port to a power source, the LED status indicators will start blinking to indicate recharging. The lights will turn off after 30 seconds allowing for a good night’s rest. Remember to check the status indicator before you disconnect. When all four LEDs are lit, your powerstation battery is fully charged.
    How many times can I recharge my powerstation battery?
    You can recharge your powerstation battery for over 500 full cycles. A full cycle is when you recharge the battery from 0% to 100%. Partial cycles, like charging from 25% to 100%, will not count as a full cycle until all of the partials equal 100%.

    For example, if you recharge from 25% to 100% one day (a 75% charge), then a couple of days later you recharge from 50% to 100% (a 50% charge), and a few days after that you recharge from 25% to 100% again (another 75% charge), you will have recharged two full cycles over that period (75% + 50% + 75% = 200%).

    After 500 full cycles, the powerstation battery may provide less than 75% of its original capacity. This is normal for any product with a lithium polymer battery.
