As smartphones are used more and more as an infotainment device, many users complain how quickly the battery of their handsets drains. If you own a Nokia Lumia 920 and are tired of re-charging the battery frequently, you can now easily double the batter life of your smartphone with the Pocket Jacket extended battery case for Lumia 920, which adds an additional 2200mAh battery capacity to the phone.

The Lumia 920 is currently one of the most popular Windows Phone 8 (WP8) powered phones around. The Power Jacket case for the handset is made exclusively for Lumia 920, which provides an additional 2200mAh battery for the handset, protects it from dents and scratches, and the kickstand offers an enhanced video watching experience to users.

The Power Jacket case has a battery indicator on the rear of the case, which tells users when they need to recharge the battery. However, the addition of 2200 mAh battery on the Lumia 920 comes at the cost of extra bulk. The Lumia 920 along with the Power Jacket case weighs over 260 grams (9.17 ounces) and has a combined thickness of about 20mm (0.78-inch).

The Pocket Jacket is easy to attach to your Lumia 920 and all ports and buttons of the handset are accessible even with the case on.

The Pocket Jacket extended battery case for Lumia 920 is available in black and white colors only. If your Lumia 920 is any other color then the Pocket Jacket case may look a bit odd. The case can be purchased for $37.
