I'm having my house (in the UK) rewired and want to install some PIR sensors (link) in a few rooms. Instead of using batteries there's an option to have them permanently powered via USB cable. Is there a device (transformer?) I can have my electrician install to step the mains power down and provide a permanent USB supply?

Thanks!

EDIT: Maybe something like this is what I'm after? A 240V to 5V Switching Power Converter. Unfortunately there's not much info on it...

EDIT2: Thanks for the help I've found what I was after: USB Euro Module Charger

Transformer, rectifier, regulator - aka, a USB power supply.

There are, of course, the small switching supplies that plug in, as seen as phone, ipad, ipod (or any other USB device) chargers.

I know that there are power outlets (ac) with built-in USB outlets available for the USA system - depending on the speed and conservatism of the UK electric regulators, that sort of thing will either exist, or be coming at some point. Looks like it's a done deal:
