Haven't posted in a while and doing it mobile so forgive me if I mess up a bit. I saw this in a local Walmart clearance area for $1 and couldn't believe it so grabbed every one they had for use, stocking stuffers, and just to give away to fiends, managed to get 20 of them. Checked brickseek and a decent number of stores nationwide have it for $1, bunch for $2, even more for $3, etc. It's pretty basic, just 5v 1a, built in lightning cable for iPhone/iPad and comes with a micro USB cable for the 1 USB A port for output. It's pretty light, simple plain white plastic and is about the size of a deck of cards(bit taller) brand name is Auto Drive, registered trademark of Wal-Mart distributed by Wal-Mart yada yada yada. Cheap back up power I can leave in the car, diaper bag, tool bag, etc.
