This is because the device that plugs into your cigarette lighter does
the 12V - 5V conversion for you. I used to use one of these and
bought a female cigarette lighter adaptor to plug it into.
This allowed me to break out 12 V for the Volkslogger to drive it and
5 for the iPaq.
In my older age I got lazy and just bought a pre-built box from craggy
aero (www.craggyaero.com) because it was a lot neater than what I had
cobbled together (although it worked just fine)

Hi Robert,
Thanks for your advice. The HP ipaq I have also does Tom Tom
navigation on my car so it spends most of its time on my windscreen.
Because it already has an internal gps I don't intend connecting an
external one to it. The USB currently plugs into a cigarette lighter
adaptor and then runs of my cars 12 volts. I want to plug it into my
glider but without the cigarette adaptor.
I think I need to find what voltage is powering it first.
Regards
Don.
