Does the job
The price may seem high, but I didn't want to take just any sub-brand device bought on amazon, for safety and to be able to come back to LDLC in case of concern.
As for the use I can't check all the points of the description, for example "Intelligent charging system that provides the right power for each device" nor the protection against overcurrent, but for the rest no problem: It charges the devices, even several at the same time, it doesn't heat up much, it's quiet.
The power supply unit is rather large, but flat, so that it can still be stowed away.
