iPhone 4, 4S and 5
This iPhone battery case is probably the cleverest case you can buy! The fully protective form-fitting case comes with a built-in rechargeable battery to extend your battery life just a little longer. The durable and stylish case offers the full protection of a hard-shell case with protective shock-proof rubberized band protecting your phone from bumps and scratches and light drop impact. The case also comes with an included standby switch allowing you to choose when you want your battery pack to kick in and the included micro USB cable allows you to charge and sync to iTunes.
Samsung Galaxy S3, S4 and Note 3
Get that extra boost of battery life when you need it most with the Samsung Galaxy battery case for either S3, S4 or Note 3. Works as both an external battery set and as a protection case whilst allowing full access to all the functions of your phone. It is padded to provide good protection against minor impacts, but is still thin enough not to add much bulk to your device. Coming with all the button cut outs you need, the case does not impeded performance. To charge the phone, simply slide your phone into the power case and make sure the phone is connected to the 30 pin dock on the power case, then press the ON/OFF switch.
