Hack Together A DIY Emergency Car Charger With A Cigarette Lighter Adaptor

If you're on a road trip and find that you forgot your car charger for your phone or other USB device, Popular Science shows off how to make one on the fly using a USB cable and any 5-volt car cigarette lighter adaptor.

The process is incredibly simple. All you need to do is cut the USB cable, and strip the insulation to reveal a red and black wire. Do the same to the cigarette lighter adaptor. Finally, twist the black wires together, then the red, and wrap some tape around them to insulate them. When you're done, you've created an emergency car charger that works just about as well as anything you'd purchase at a store.

    Note that this article requires you to have a 5V cigarette lighter power adapter (ie for an old Nokia)
    You can't just use the power direct from the cigarette lighter as I initially read it.

    Since its only really useful in a car, I'm not sure why you would even take the car charger out of the car to forget it in the first place.

    or you could just spend $20-$40 and buy one and save yourself the hassle and potential of destroying the interface on your gadget! seriously they are not that expensive anymore and phone chargers are practically at every petrol station these days.
