Searched Fleabay but no luck. I'm after a USB lead with a male end and 2+ Female outlets at the other so I can have multiple devices connected from my single Optimate USB outlet lead mounted next to my Dash. IP rating would be even better but I doubt such a lead exists.
I have a cig socket in tail unit that is perm live - I think plug in a twin USB outlet when needed - it can drive sat nav and charge a phone - if you stop for a long time turn unplug it , but often leave a phone / gopro plugged in to charge over lunch / at coffee stops - is that a help ?
No, I need either what I've posted above or a twin+ outlet with a flying lead that I could connect direct to the battery. Either way I need the USB outlets at the Dash end. Looking at connecting the Sat Nav, the iPhone and a Vid camera.
I too have a double USB socket that connects permanently to the battery. Haven't got it connected just now though, only have the optimate quick connection attached right now. But had it on last year and it didn't drain the battery, and charged the phone very quickly too. One lap of the TT course and it was fully charged.

Found something even better! http://www.amazon.co.uk/Hama-USB-2-0-Hub-Bus-powered/dp/B0017X0R20/ref=pd_cp_computers_1
Be aware that the more devices to connect to one socket, the lower the current supplied to each connection. So you may find charging 2 devices from one socket takes longer than just 1...
