A wireless charging iPhone 5s battery case? Why, yes please! You mean you can finally experience what it is like to wirelessly charge an iOS device and be protected with the convenience of a slim battery case? Stop the madness. And no, this isn't sarcasm but a genuinely thrilled response to what may be one of the most practical accessories made for the iPhone that we have ever come across. It's called the Aero, and it's made by a company called Unu. While not entirely distinct, the Aero is one of the very few wireless charging battery cases available for the iPhone 5s and iPhone 5 that packs a fairly large internal battery capacity (2000mAh mind you), into a very sleek and slim form factor. To some this may be a dream come true. To others however, the thought of adding bulk no matter how useful it may be is a ridiculous idea. So how good is the Aero as being both a battery case and a wireless charging gateway all in one? You can of course find out when you reach the full and very much comprehensive review down below.
