Hi, I'm setting up a new installation in house and would like to have a wall-mounted iPad3 for controlling the smart house installation. They have a very nice USB charger socket in the same design as all the switcher and sockets... However the current that comes out is only 7w and i'm worried it might not be enough for charging the ipad. Any experience with this? I would really like to have this usb socket as it keeps then the same design of all other switches in the house but would like to make sure it will work as it is quite expensive... Many thanks in advance to anyone who can help me with this! Cheers!
