Regulator transformer.

Certainly a cheap solution but i doubt you'd be able to pull 3A off it though.

Not exactly..

A regulator regulates voltage.

A transformer transforms voltage and current up or down

Physical connectors can be had from eBay, Amazon, CPC, Farnell, Maplin. But do realise that USB is 5V not 12V so you'll a regulator circuit to reduce the voltage (an example http://www.instructables.com/id/Portable-USB-Charger-1/).

Easiest option would be to dismantle a USB car charger and fit that to your car.

I once bought a cig ligher fitment, took it apart and wired it into my 12v... and blew it up :lol:

The 5v thing probably explains it :|

Just to charge stuff with? Something like this?

I think USB is 5V by the way. That's the extent of my wiring knowledge though i'm afraid :lol:

First off where do you buy them from? Tried searching Amazon but that just brings up the 12v ones that have USB on top of them which is not what I want.

Secondly, when wiring it up I'm guessing that the easiest route would be to feed the wires to the 12v./cigarette lighter?
