12volt DC Mod charger

that thing looks cheaper can we make our own anyone know how to wire it

Should be able to build one much cheaper, a bridge rec (about £2) to first rectify the AC. Just Google the 7812 for smoothing cap values.
It may even be worth looking at 7805 regs to feed out straight to a usb connector.

Is there a potential problem in that at low revs it won't be generating 12v. A gps for instances, takes a bit of time to find and connect to the satellites, so at low revs it would switch off then re-start when it reaches 12v ....then switch off again at low revs.

I buggered my samsung galaxy using a gps app' on the Li and that was through a battery....some electrical appliances are a bit sensitive so be careful !!

Couldn't post a circuit diagram could you mate? It would be really interesting! You made it sound so simple
