Power o/p (W) of shaver socket?

Anybody know what the power o/p of a normal bathroom light/shaver socket is?
I would like to power my pi radio using it, but need about 7W.
I have a 2pin 5V2A psu that will fit but before using it I want to make sure I don't overheat it.

7w is fine.

Bear in mind that a Pi can take up to 10W and at an efficiency of say 80% for the mains adapter you could potentially be drawing 12-14 watts from the socket.
In reality though it will be less than this unless you're watching 1080p movies in the shower. Shaver sockets tend to be rated for 20-50 watts anyway.

As I said its for my pi-radio, drives a 2x16 lcd & a pair of usb powered speakers.
OK will give it a try and see how it goes. I normally use my EEE on battery driving the speakers, but thought I could get away using the pi-radio driven by the socket.
Only for short(ish) times anyway (<1hr) not continuously.
