The iPhone is one of the more popular smartphones out there, not to mention desirable. After all, plenty of folks have already purchased it, and we do know that the iPhone is an extremely capable phone, but one thing that plagues it (just like any other smartphone worth its salt in the market these days) would be the lack of battery power to pull it through more than a full day, assuming you use it and the various functions to the hilt. Enter this portable battery backup that resembles a plug, and what do you know – it is also known as “Plug”, sporting a removable cap that exposes the iPhone 30-pin connector in the process. Out later this April, it will be able to hold a charge that juices your iPhone by another 30%.
