USB cable for your device
Any 5-volt car cigarette lighter adapter
Cut the USB end off the cable for your device and strip the insulation. You'll use the black and red wires to connect to the adapter. Twist together the other two wires.
Cut off the end of the cigarette lighter adapter that does not plug into the cigarette lighter. Use the knife to strip the insulation to reveal the black and red wires.
Twist the two red wires together and the two black wires together. Wrap tape around the joints to insulate them.
Plug it in and charge up your phone in the car.

Nice car! Lame hack and opens a large opportunity to send 12 to 18vDC accidently to your nice expensive device. Sometimes high voltage blows devices and sometimes getting the polarity backwards blows the same device too. Perhaps you should get a volt meter\multi meter and check the voltages in advance.
Common to computers is turning off your usb device prior to unplug, else harm might come to the device or computer.
I see lots of things that can go wrong, if a novice does this.
in case of emergency go to any gas station and they will have the proper adapter with USB out port, for 5.00 ( well in N.A anyway ) it seems...
^ yeah somehow that concept escapes the gas stations here in upstate new york.
in case of emergency go to the back of your house, find an old car charger, cut the wire off at about halfway, strip them, then splice them with usb charger cable for device.
to mars or bust!

Soooo, in an emergency, I just happen to have an adapter already available, wire cutters\strippers and usb cable too, really, really? And the adapter I just found I have for an emergency will convert 12 to 5vDC and not fry my cell?
Maybe, if I am going to have all these things about, just in case for an emergency, I will stop by a gas station in advance and just have a cell phone adapter charger already available, just in case for an emergency too, lol.
I got a usb modulator which accept a normal usb flash drive as an input device and fit the cigarette lighter as the power source, i bought this 6 years ago,for 15 Saudi Riyals less than 3 USD dollars, it charges my 3 cellphones -2 get outdated,my camera,sometimes i left it "on"for 1 day and 1 nite. also buy another charging cord and have it exclusively always in your car, never take it out,no over voltage, no hustle,
Hey what a great hack. I mean who doesn't have a 5 volt cigarette lighter adapter in their trunk. I bet if I look in my trunk or the trunks of anyone of my friends or your friends for that matter, they'd probably have at least 5 of them laying around. And a wire stripper, and tape. Not to mention a cable that you don't mind ruining for the use it was designed for. Or a cable that you can strip that has two nicely defined, easy to pick the red and black wires out of. Most that I have run into lately are so thin you can only strip them by burning off the "insulation" which is really painted on the wires. And just try to twist them together. Not happening. But what the heck, maybe if you are that desperate to use your cell and don't have enough sense to have a charger in your car, Hey, this hacks for you!!
Really, maybe it seems I got out of bed on the wrong side this morning, IDK. But I think anyone serious enough have to get what I am saying. Buy a car charger, or two of them if you want. It beats the heck out "hacking" something together with 1) cable that you don't have 2) a wire stripper you don't have, etc. etc.
блин в России давно так заряжают, а вы только сейчас до этого додумались...
