Review on Smart USB Charger with Auto Stop Function LED: Charge 2 Devices Simultaneously by Jeremy Lunn

I wish I could give negative stars. After I tried screwing the charger into my pen the first time, the plastic case cracked and the wires snapped, rendering it unusable. At first I thought it was my fault so I tried the same thing more cautiously with a second charger but the same thing happened. Now useless junk and waste of money
