For less than 7 euro's i bought this power socket with 220V and USB (inbouw stopcontact met USB aansluiting) at the Action in Almere (The Netherlands).

It is always nice to have USB power ( e.g. for home automation projects) and i also wanted to know if it is easy to modify the circuit to control the 220V socket with a relay.
I decided to open it on the backside, here are some photos's
