Make You Car Charger for your cell into a USB Charger

Here is a really easy hack you can do to your car charger for your cell phone. I don't really know if anyone wants to do this, but I did and so I thought maybe someone else does. The reason i did it was..

I only had 1 charger for my phone and it was a car charger. I live on the 2nd floor of an apartment. I didn't want to have to run down stairs and plug my phone in my car. Also theres the risk of theft or missing a important call.

So here's how it's done:

1. Cut your Car Charger cord, Closest to the part that plugs into your cigarette lighter so you have lots of cord to work with. You really wont need much though.

2. If you have an old USB cord sitting around in your house cut that furthest away from the USB plug again for more work room.

3. You going to strip the ends of each cord, and get the Red and black wires out. Cut off the rest of the wires.





4. Strip the red and black wires from both cords and connect the black wire from the car charger to the black wire on the USB by twisting them together. Do the same for the red wires.




5. Now with some electrical Tape, tape the 2 wires separately so the wires don't cross. after that you can tape all together to make it look nice.

 Your done! Now just plug this into the usb on you computer or even your xbox 360 and the other end to you phone and it will charge it!. Thanks for reading hope someone can use this.

Thanks bro...I acutally used this concept to rewire a usb to my car charger for my blue tooth. So I can charge both my phone and blue tooth at the same time.

Huge help. Gracias.

Lol. I was looking at the tangled heap of cables and wondering if this was possible. Took me 2 days of deliberating before I bothered to google it, hit this page and YES! You gave me the confidence to try it.. and my phone is charging.

Thanks--great instructions, only we didn't have a black wire on the usb, so we attached black to white and it worked perfectly.

I like what you did but I have one suggestion. There's nothing from stopping you from also connecting the car adapter as well so it could have dual use.

Many devices now come with A/C charges that have a USB output port so you could use this with that of course as well. The PC outputs 500 mA but a lot of charges often put out from 750 amps up to 2 amps for ipads, etc.

You might have to incorporate some diode or resistor into the lines from the car adapter to prevent reverse current but I doubt that would be an issue.

TO Ramans / Johnson, You can get a micro USB board that has simple battery +/- inputs (solder) and a USB output. Simply put this with a 14500 or 18650 battery (or two in parallel, 3.7 v each, 14500 is same size of AA and learn about them on which will give you great portable charging power.
