USB power adapter cable which is +/- on the cable ?

[invincibl3]

I need to wired the phone to a 12v constant. My plan is to splice the usb cable and connect that to a 12v constant. My question is on that usb cable how do i tell which is the + and which is (-) ground (on the usb cable that is going to be spliced [the power wall adapter that comes with the phone).

the phone is the i355

I was thinking the same. Bat life I got is about 15 hours.

Link I found on color codes......

Red is 5v+ and black is N .

? is can the Phone handle a 12v direct input without a convert ??????

You can't do that. You will blow up the phone.

USB power is NOT 12V, so you can't cut the end off your home/wall charger like you indicate in your post.

If you want to go the cheap way like that, you will need a mobile car charger - one that converts 12V to the proper USB charging levels.

cheap way? im just want to hard wire it to my car soo it uses the cars battery, and in the event that the batery is removed the phone battery will kick in. what would you suggest?

So buy a car charger, and a either wire 12V to the end of the car charger, or get a female cig. lighter receptacle - to make it look neater - and wire a remote one that way.

Guess if you do install a spare cig outlet some where. You could just use a auto charger or get one one of these USB adapters .

I would imagine that most cars have spare hook up points ?

Still looking around...

i got mine working the "cheap way" i went and got a cig socket at radiot shaq one that has a inline fuse on the red wire and a black for ground. Found a 12v constant on the car... hoked up that red cable to it and the black cable to ground source. then got a car charger for the phone and pluged it up to that cig lighter socket and boom. works like a charm. the phone is using the cars bat/charging, once the cars bat is removed the phone bat will kick in.
