Make a Zen Micro/USB Wall Charger From a Phone Charger





Introduction: Make a Zen Micro/USB Wall Charger From a Phone Charger

Use an old cell phone charger and a usb socket extention cable to make a wall charger ( this does not come boxed with the zen micro and costs £30 ). This is very easy to do.

Step 1: Get a Cell Phone Charger, One That Will Charge at 5 Volts ( the Usb Voltage ) It Should Say This on the Charger. I Use One From a Sagem MyV-55. Cut Off Phone Input Socket and Expose the Wires.

Step 2: Get a USB Extension Cable With a Type a Female Socket on It, Cut Off the Male Socket and Expose the Wires.

Step 3: On the Phone Lead the Red Wire Is Power and the Black Is Earth ( Use a Multimetre to Double Check )

Step 4: On the USB the Red and the Black Correspond, Cut the White and Green Back Out of the Way They Are Not Used

Step 5: Solder the Matching Wires Together and Tape Them Seperatly, I Have Also Use Heat Shrink Tubing (put It on the Wire Before Soldering)

Step 6: Plug in and Your Ready to Go, This Worked for Me No Problems and Took Only 15 Mins

    I am trying to make a solar charger for my cell phone. So would the black  go to black an and red to red?(sounds like a stupid question, but just want to be sure.

    I don't know if your question was answered or not. I can tell you that if you are using a solar panel without a charge controller, at the very least you should insert a diode on the panels output to prevent it from draining your battery when the light level drops or night falls.

    Oh and yes, Black to black and red to red.

    it is not a real Zen micro USB wall charger. I think it can't be fast charging.
    You have to deal with the D+ and D- pins, resistor is needed to add.
    a post for this problem:

    I don't see the point of hooking the phone charger cable to a female USB plug, only to then plug a standard USB cable into the female USB plug. Why not just solder the phone charger cable to a stripped cable that goes directly to the small male USB plug that goes directly into the MicroPhoto? Is that one extra connection necessary for some reason?

    Tried this on my Creative Zen, works great. USB cable made in China wire colors not standard.figured them out with the help of a USB diagram. thanks.

    Tried it. It worked. It even works with 5.2v and 800 mA. Used it to hook up speakers in my rec room, i can charge and play my mp3 player at the same time. Great instructable!
