Charging your juice pack case
Your juice pack case comes charged and ready to go.
When it does need charging, use the supplied micro
USB cable to connect it to your computer or any
power source with a USB out, like the USB wall adapter
included with your iPhone. Normal charging should
take only two or three hours for maximum power.
