Scosche has announced that it is now shipping the goBAT II portable battery charger and back up battery device. The little gadget is an external battery that has 5000mAh of power inside and has dual USB ports. That means that the gadget can charge two gadgets at the same time.
The only downside to having a battery that has a USB port is that you need to take your charge cables with you to charge. According to Scosche, a dead iPhone 4 can be charged 2.6 times on a fully charged goBAT II. The battery has enough oomph to charge the iPad more than halfway as well.
One of the USB ports on the device has 2.1 amps and the other is a 1-amp port. The time to charge the battery inside the sleek little goBAT II is 6-8 hours. You can order one up right now directly from Scosche for $89.99.
