Sick of dead batteries? The Powerbag Backpack is equipped with a battery system powerful enough to charge the average smartphone twice. The dedicated laptop compartment provides extreme protection. The contoured straps and back panel are designed to keep you comfortable even when your Backpack is filled to the brim.
The built-in battery system charges the average smartphone twice and includes Apple, Micro-USB and Mini-USB connectors and a USB port. Charge literally hundreds of devices including smartphones, eReaders and many tablets. Tablets must be charged with their own USB cable through Powerbag's on-board USB port.
The logo button turns Powerbag on or off when you press and hold for 2 seconds. Or press the logo button once quickly to see how much power you have left. When it's time to recharge Powerbag simply connect the included AC adapter and plug it into a wall outlet.
