Charged it once, worked fine. Charged my iPhone 4 about four times from around 10% to 100%. Battery ran out, attempted to charge it a few days later and it wouldn't charge. It blinks as if it charging but it just gets really hot. There's only one button so there's virtually no way to troubleshoot it yourself. This thing is a piece of junk.
