Your powerstation battery comes charged and ready to go. When it does need charging, use the supplied micro USB cable to connect its micro USB port to your computer or any power source with a USB out, like the USB wall adapter included with your device.
The powerstation 5X and powerstation 8X batteries have 15W Fast Charge input charging capability when you recharge them using the mophie USB wall charger with 15W Fast Charge capability.
Priority+ pass-through charging
The powerstation 5X and powerstation 8X batteries have pass-through charging, which enables pass-through charge and sync when the powerstation battery is recharging from a computer. Your connected device recharges first, then the powerstation battery recharges.
Connect your device to the powerstation battery USB port that is marked with the Priority+ charging icon:
Although the powerstation 5X and powerstation 8X batteries can charge two devices simultaneously, they can only charge one device while they are being recharged. Connect the device to the powerstation battery USB port that is marked with the Priority+ charging icon. (The other USB port is shut off while the powerstation battery is being recharged.)
