The material outside is a white plastic housing, frosted, so that you can still see fingerprints neither scratches. At the bottom are four small pads to keep the port slip on the table.
4 USB ports are available. It's a smart charger. Output 25 W, ie 5A. Is current on the port, so a blue LED lamp. The shop is good and consistent. However, I've noticed that the USB port is hot and which is also the star deduction. This change bulbs gives me a slightly uneasy feeling, so I decided not to go away from home when loading and prefer to stick to it. It may be that this heat generation has to do with being too light inside the port. In the light weight can not put a lot of insulation or protection there.
