Compact Design
PowerDrive 2 Lite is slim, sleek, and incredibly compact to stay out of the way when plugged in.

For Optimal Use:
• Use your original cable or a third-party certified one (such as MFi).
• Compatible with the new 12" MacBook, Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices except for the iPod nano, iPod Classic, iPod Shuffle, HP TouchPad and Asus tablets.
• We recommend charging your MacBook while it's turned off or in sleep mode (5-hour recharge time).

Note:
If a port isn't working properly, your device may have triggered the protective internal safety switch. In order to reset the switch, unplug all cables for five minutes and retry.
