This is such a unique power bank! I really like that this one is a shake to activate type of bank instead of a button. I found that at times I would click the button and drain the power when I didn't even know it. With this bank the power shut off right of way so you don't have to worry about your power going out. This has a good amount of weight to it and I really like the quality of this bank. There are two ports to charge from and it uses a micro USB to charge the bank itself.
