Charging works very well.
The cable supplied in the box is black, which is odd with the charger which is white.
But I guess that's why LDLC added a white cable to my order, thanks!
You have to find the area where it's charging, but the LED that lights up to indicate that it's charging removes this potential problem.
The LED changes from blue to red when the phone is 100% charged.
However, this LED cannot be deactivated, so if you plan to charge your phone in your bedroom overnight, get another charger.
I tried this with my first mains adapter, which wasn't very powerful, and it didn't work. I tried another one (1A) and no problem.
