If you have a couple of portable iDevices and use them constantly, and are frequently on the go, then it would be difficult for you to rely on just the internal battery of the devices. Mophie's Juice Pack Powerstation Duo enables you to charge two iDevices simultaneously, on the go.

Mophie's Juice Pack Powerstation Duo features a high output battery that provides ultra-fast charging for your iPod, iPhone, and iPad. The Duo charges your devices with up to four times when compared to the current traditional 500mAh batteries. Additionally, the Duo also offers the ability to switch between a 500mAh charge, a 1A charge, and 2.1A level that's ideal for iPad.

The Duo includes a 6000mAh rechargeable lithium-ion polymer battery. The device has a mini USB port for charging itself and two standard sized USB ports optimized for connection to your iPhones, iPads, and iPod touch devices.

The device has a sleek design with four LED status indicator lights, which disappear when you are not using the battery. The Duo measures 2.28 x 4.3 x 0.77 inches and weighs 7.05 ounces and can be used on the go when traveling, in a car, at home, or in a plane.

"It is very easy to just keep my iPhone and iPad in my backpack connected to the Mophie Duo when I am running low on battery. The Mophie does a great job charging my iPad mini and my iPhone 5. It is able to charge each of them up quickly. The Mophie Duo's internal battery is large, sporting 6000 mAh of juice capacity. That is just enough to fully charge both an iPad mini and an iPhone 5 up completely," notes a recent review of the Duo by 9to5rumors.

If you are looking to buy the Duo then the device is available in black and white colors and is sold directly from the Apple Store for $99.95.
