The growing popularity of tablet computing has brought with it another challenge in the ongoing battle to keep your all your portable devices charged when off the grid. Scosche's solution – the goBAT II Dual USB Portable Charger & Backup Battery – pairs a 5000mAh rechargeable lithium ion battery with dual USB outputs, one of which is a 10 Watt (2.1 Amp) port to meet the power requirements of tablets as well as a standard 5 Watt (1 Amp) port for practically everything else.
The goBAT II mobile battery pack contains a LED battery level indicator showing you how much power is left in its battery and works with the company's reVIVE app, a free program that shows you how long your device will take to charge as well as the ability to email you to let you know when it is finished.
The device takes 6-8 hours to fully charge and has enough power to charge an iPhone 4 two and a half times, an iPhone 3GS three times and the iPad's 25 Watt battery to 55% without a wall socket in sight. It also ships with a USB adapter for the Galaxy Tab.
The Scosche goBat II costs $89.99.
