The Apple iPhone is one cellphone that packs in a lot of multimedia features in addition to the regular calling and texting features. More often than not, iPhone users find their iPhone battery running out of juice when they need it the most. To get around this tricky problem, we have the iPowerJacket which is basically an iPhone skin which doubles up as a ready source of charge for the iPhone. The sleek loking leather jacket has a lithium ion battery built into it. As and when your iPhone runs out of juice, you can switch over to the iPowerJacket’s battery for power. This certainly is good news for people who travel a lot. The iPowerJacket sells for $79.95 which looks pretty reasonable, especially for the amount of functionality it manages to pack in.
