Hello Elisabeth, 
Yes, the technical data is a bit sparse. Here is the most important info: 
Output voltage: 
3 / 4.5 / 5 / 6 / 7.5 / 9 / 12V (1000 mA across all voltage ranges). 
and of course the following would also be helpful: 
Adapter plug: 
2 USB adapters: micro USB plug and USB type A socket. 
5 DC plugs: 1.35 x 3.5/1.7 x 4.0/2.1 x 5.0/1.5 x 5.5/2.5 x 5.5 mm
