I have previouly bought an Ex-Pro charger for a computer. It was of excellent quality and so is this. It is small and lightweight. You can use it for considerably periods, and it does not become hot despite the small size. Your USB cable to whatever device is being used has to hang out of the bottom of the charger, but the grip is secure and this does not cause a problem. Also, being white, you can "store" it by switching the wall socket off and leaving it plugged in. Once it is switched on, there is a red warning light, so you won't leave it on by mistake. Switched off at the socket, it blends into the background without looking untidy.
