Delivered it was quite quickly thanks to the FBA (Prime). The PSU comes in a small cardboard box and stock up on a small leaflet nothing of it (why?). In the outlet plugged, and of course the same functional. Then I got myself and seen what comes out my current USB meter and my iPad. According to my instrument there are 2.2A and 5,07V and so everything in very good area. Since this power supply 2 x 2.4A I additionally connected yet another tablet and the current was sufficient to both tablets to load at full strength. When charging, the power adapter gets only slightly warm. What you should still be aware: if you want the power supply hanging in his bedroom, will not be happy. Is on the front cover of the Blue (where i-smart draufsteht) is illuminated by a LED and illuminates the space according to light ... I have all my taped with electrical tape and the connections cut free now all is well!
