I got this on clearance for an excellent deal. The size of this works well and I like that it has a kickstand in the back. I was also worried the charger might not work with a phone case on, but it was fine. My only cons for it is that the cable doesn't always charge on the first try when I plug it into a brick. The cable also gets in the way a bit when I'm holding it but you can remove it so it's not a huge deal. For the price, it's awesome.

Good product but needs a USB "A" cable end for charging. The supplied cable has two "C" ends only.

Couldn't find a credit card size battery so decided to try this tho hesitant. Altho heavier, turned out to still be good: actually easier to charge iphone on the go without having to hold onto it, esp using neck cord. Wished the cord didn't stick out and had usb plug.
