Simply use the cable that came with your smartphone or tablet device to connect the Powerstation Duo.

View Mophie's online compatibility chart for tested and confirmed devices that work with Juice Pack Powerstation Duo.

USB Connectors: The Mophie Juice Pack Powerstation Duo is fitted with two USB (type-A) ports and a micro-USB (type-B) port. The USB (type-A) ports are used to power and charge your smartphone and/or tablet device, individually or simultaneously, using the cables supplied with your mobile devices. The micro-USB (type-B) port is used to charge the Powerstation Duo's battery pack, using the included 31" charging cable.

Rechargeable Battery: The Mophie Juice Pack Powerstation Duo features a rechargeable lithium-polymer battery rated at 6000mAh. This high-output battery provides ultra-fast charging (2.1 amps) that is 4x faster than traditional USB batteries. Additionally, improved conversion efficiency means more power actually makes it to your connected mobile device. To charge the Juice Pack Powerstation Duo, simply connect the device to your computer or a third-party USB wall adapter (sold separately) using the included micro-USB-to-USB charging cable. The battery pack is rechargeable for over 500 full cycles. Partial cycles don't count as full, so you can charge your juice pack 10% of the way ten times before you get to a complete cycle.

Note: You cannot charge the Juice Pack Powerstation Duo battery pack and your smartphone/tablet devices at the same time.

4 LED Indicators: You can determine the amount of juice the Powerstation Duo has by pressing the status indicator button on the side of the device and checking the 4 LEDs. When the button is pressed the LEDs will illuminate for several seconds. Four LEDs means that the juice pack is fully charged and one LED means that it's almost empty. The LED power indicators will blink when charging. As the Powerstation Duo becomes more charged, the LEDs will indicate how full it is, but one LED will remain blinking until completely full.

Protection Circuitry: The Juice Pack Powerstation Duo external battery pack features built-in short circuit, over-charge, and temperature protection.
