holds all the promise of what the manufacturer promises. The device comes packaged very well back home. Included is the USB adapter itself, and a power supply and an easy-to-understand German (others) instructions. The adapter works easily and is marked with the appropriate amperage (see manufacturer's instructions). Beautiful is also that the manufacturer has been received with criticism of pre-extant. By that I mean that the LED light is blue-garish, but now solid green (ie, the "floodlight" away ;-)). I am totally satisfied with this 6-port USB charger and can only recommend this.
