Avoid that dreaded dead battery on your iPhone, iPad or other USB device with the Scosche goBAT II - Portable Charger & Backup Battery. This handy backup battery and dual port charger has an internal 5000mAh Lithium polymer battery to keep your devices going and going when you need them most. It's great for long commutes, traveling, camping or anywhere else you need on-the-go power.
When your iPhone 4 is totally drained, you'll be able to charge it 2.6 times when your goBAT II is fully charged. Or, you can charge your iPad up to 55% of a full charge. The goBAT II features two USB charging ports that can be used at the same time. A 2.1-amp port lets you charge mobile devices like a tablet (iPad and Samsung Galaxy Tab). The other USB port outputs 1-amp, so you can charge other devices like an iPhone, iPod and more. Plus, four blue LED lights let you know just how much battery life is left on the battery itself. You can download a free app for advanced battery management.
To start charging, simply use your existing USB cables to plug into the ports on the goBAT II to begin charging your devices. And don't worry about using your devices -- you can keep on using them while they are charging. When it comes time to recharge the goBAT II, use the included Micro USB cable. True to its name, the goBAT II is also built for a life on-the-go. It is compact and fits into the palm of your hand, or can be slipped into luggage for take-anywhere portability.
