    Looking for ideas for a kit for a new system we are testing.
    Anyone know where I would get something to step down 12volts dc to power a USB device .

    A car USB charger would do that. Some of these can supply up to 1amp.

    The likes of maplin have cigaret lighter sockets on a flying lead you can use to power these...

    Lol, simple is always best.

    Places like Harvey Norman sell these off in bargain bins for less than a fiver. Even some spar shops sell them. Most are a little switcher, so quite efficient.

    Very low power. It's to power a WiFi adapter in an alarm panel.
