USB- U Portable Charger

USB-U is basically three double A batteries shoved in an Altoids box. Why am I so excited about it? Because it charges your phone!

This is amazing because all other portable charging devices are usually made of lithium ion batteries, which are great, but they also have to be charged. USB-U means that when your phone dies on you, all you have to do is stroll down to the nearest convenience store and buy some double As.

USB-U is creative because it takes simple elements and combines them to form something super-helpful.
