Those of you who just can’t get enough out of your current Samsung Galaxy SIII battery will be pleased to know that PowerSkin has announced they will be selling a case soon for your precious Galaxy SIII. PowerSkin cases, for those of you who don’t know, slide on around your phone and plug into your micro-usb slot. The case itself has a battery built inside of it so energy is pulled from within it first instead of your phone’s battery. The best part about it is that the battery will not hinder your use of NFC. Pre-Orders have gone up for it for $62.99 on the PowerSkin website. Also for any of you who have older Android phones, such as the Galaxy S, Nexus S, or the Thunderbolt can benefit from the current sale they are having and get your very own PowerSkin case for only $19.99.
