So why only 2 stars? - Now for the problems of this device:
The one different devices can not simultaneously load so is clear to me, but if it for example, someone using no idea of technology has, such as a small child is, incorrect operation is not excluded. It could happen then that several devices can be connected simultaneously and the charger is overloaded, which can lead to overheating. So for children it would be better if you would ensure that only 1 cable can be connected at the same time, allows either a switch or a plug of only 1 adapter. Personally, I find it convenient not to have to reposition and change, but as I said in children that could be dangerous.
In my unit, there was a small but dangerous production error. When I tried to pull it from the wall outlet, flipped open the device housing and the Elekronik including 230 volt part was open. No problem for me, because I know where I can go and where not to intervene, but for a child could be very dangerous. Screw the housing holds together was not fixed inside and fell out.
I'm sure Amazon would have replaced the device immediately without hesitation, but I did not want an extra run for such a small thing to the post office and have simply screwed purely a slightly larger screw and now holds the housing. I very much hope that this other devices is not the case and I would just get just a Monday device.
All in all I am satisfied with the product, but a child, I would not give the equipment unattended in the hands.
