Chipstix

OK cheers, that's one option.

I would still prefer a solution that completely removes the need for any cigarette lighter connection point, as this is a bit messy and probably the worst possible connection for vibration/use on a bike.

Would much rather a simple wire with a tiny step down bit of circuitry terminating in a miniUSB. I already have 12V pumping around the bars to power the heated grips, so could possibly tap off from that.

Or other option is to move the existing optimate hardwire charger lead from behind the airbox cover to up near the bars (then I can share the connection point as will not need to power SatNav and Optimate battery at the same time).

If I can find the 'tiny step down bit of circuitry', I can do the rest....though a nicely made complete solution would be the best!
