The ideal solution for charging two devices simultaneously. PNY's 7800 PowerPack is made of a high-end brushed aluminum housing, offering users a compact, portable and stylish design. Convenient in size to carry in your pocket or purse. The PowerPack comes with a 20" Micro USB cable for charging the PowerPack as well as Micro USB devices (Android, Windows Mobile, & BlackBerry) – if using an Apple device, use the included 50cm Micro USB cable to charge the PowerPack, but to charge your Apple device from the PowerPack, use your existing Apple charging cable. The PowerPack can easily be charged from any USB port to keep you fully charged. Our unique Digital Display shows the exact numeric amount remaining on the PowerPack which effectively takes the guesswork out of knowing how much power you have left. The PowerPack comes charged and ready for use.
