This 4-port USB-gas station (subway station) is just awesome.
Fits with the dimensions of 68x68x28mm loose and travel gadgets. This provides a traveling 4 USB ports (3x 1A 1x 2.4A) available. A smartphone, a mobile navigation device, a ActionCam and a tablet I have already loaded at the same time. The USB charger is only moderately warm.
If you load only the smartphone you can put it in the opened USB covers.
The required power cable with Euro plug is the underground station.
The manual is available in four languages. Including English and German.
All in all a great device. Working properly, looks good and has found a special place in my luggage.
I can recommend with a clear conscience.
