Absolutely rubbish I gap where you put a battery is to big for a5V battery,id I could give it a no star I would

This is a neat little case turning a single 18650 battery into a small rechargable power bank. Comes without the battery, a cable, or any instructions but is self-explanatory. Just make sure you put the battery in the right way around! The power capacity will obviously depend on the battery you use - mine, harvested from a broken rechargeable light, is lower capacity than I hoped, but that's not the case's fault!The case has a USB A port for charging devices, and a micro USB for recharging the battery. It all works fine, but I'm deducting a star because the micro USB port is very stiff and feels as if it will push right into the case. I'm not sure how long it will last. Also, the case is very tricky to open once closed - good thing it arrived in two pieces!For only a few pounds I've taken a useless battery and turned it into something useful, so I feel this was a good buy.
