12 volt DC-DC USB charger

[pshkrdevil]

i needed to know how to make it.. i.e. what resistors you used...you are just showing off what you made without any real info..

waste of time

doesn't the USB plug need 500mA?

So does it basically convert DC voltage to AC voltage?

@latinbala4sho no, it converts 12VDC to 5VDC. it probably also limits current to somewhere around 1.5A

I bought my first Sansa and I'm charging it for the first time, but it just shows the Sandisk at 1:05, but nothing else.

Is it charging?

Hi, i'm using a 7805 stabilizer for the same purposes. But i need get more amps. Can i connect more 7805s into parallel connection?
