I think you can explain your querry a bit more in detail. Or i just see it as a useless post. As you have alreday studied mobile repairs, you also may also consided to take admisison in some English coaching class, which will improve your English grammer....
Cheers

Why can you not just fit a car cigar light socket to your bike and use the proprietry car charger for your phone?

MOTORBIKE CHARGER

Sorry I misunderstood. you could use something like a 7805/6 regulator, if the bike is negative earth (should be) you could bold it direct to frame to act as a heat sink. A fuse in line with the input is recommended. You would also need a series resistor to limit current, you could of course do this direct from 12v supply instead. Not a great way of charging lithium cells though, better to have an intelligent charging circuit. If you google you should be able to find something suitable.

Re: MOTORBIKE CHARGER

Hi sej12345, the ready made charger you are talking about with 220v input has many number of turns that will accomodate that voltage at the primary side, then to do that you have to reduce the number of turn also to the required voltage.

You cannot use this charger on DC. You need a 12v car charger.
