Our women-specific 27-liter multitasker gets you from point A to Z while keeping your mobile electronic devices powered up. The lightweight, large capacity Joey T55 power supply keeps you connected to the digital world with three-and-a-half full battery charges or several days of partial charges to your cell phone, MP3 player, tablet, or other USB devices. The rugged water- and crush-resistant lithium polymer battery was specifically designed to perform during outdoor adventures, so you'll stay powered up and in touch with the rest of your team to coordinate logistics or share action shots. Multiple internal pockets in the front compartment and the 17" laptop pocket all connect to the integrated cable system to provide flexible storage options. The lie-flat laptop pocket allows you to hustle through airport security checkpoints faster since your laptop doesn't need to be completely removed from the pack. For the ultimate in versatility, the Joey power supply can also be removed and used as an emergency power supply in other packs.
