Default [Q] Old Nokia Charger for Defy

Hello Defyers

I have an Old (small pin) nokia car charger its specs as the following

- Input 12v DC
- output 5.7 V 890 mA

I want to convert this small pin charger to a micro USB by some cutting and wiring

My concern is... if i use this charger with my Defy will i fry it...

its standard charger produced 5V , 850mA

with that 0.7V difference i might overload my circuts but it will work in the end

or i will end up with a black shiny brick

my defy is over clocked and running CM7

I've been using this adapter for a while (got it with the E52 from work). Donn't know about rewiring (might be hard to find a "blank" microUSB jack).

Cheers!

USB specs allow for a 10% voltage tolerance and that's a conservative safety margin. If your 5.7V charger really spits out 5.7V (and not 5.7 + 10%) you have nothing to worry about.
android underground

S4 Mini, Galaxy Tab, Moto Defy (rooted, overclocked, undervolted, firewalled, adblocked, cyanogenmodded, xposed, etc.)
and a couple of ancient Symbian phones (hacked)

you must strip the wires, cut the white and green and put them together, black and red leave them as they are, i have an 2000mAh charger built from a router adaptor and it is working very good, and that i have solved the problem with auto charger that is not OEM- Motorola.
