Build a 5v Usb Charger With an Old Samsung Adapter

Hello,

I have made a little instructable about how to recycle your old phone charger by transforming it into an universal usb charger.

Really easy and cheap to do.

An old charger. (mine is a old samsung charger, not usable with anything but an old samsung mobile phone)

A DC to DC booster unit (it takes 0,1 to 4,9 v and give an output of 5 v) with female USB output. 40 cents.

A Scissor

A soldering iron

Some tape

First of all, you need to cut the wire of the charger cause you don't need a lot of wire. Just let around 10 centimeter.

The wire is composed of a small white wire and of nude wire. I have put some tape around the nude wire.

Then take the little booster unit and your soldering iron. You just have to solder the white wire to the hole where "in +" is written and the taped wire to the hole where the "in -" is written.

Your universal adapter is nearly done. Now you need to tape the whole thing to make it solid an unified. On my booster unit i have carefully let the led outside of the tape so I can see it's light when the adapter is plugged in, but it's a choice to make.

You are all done now, plug something (a smartphone, a tablet, a battery bank...) in your new charger.

No surprise here, it works perfectly.

Hope it can serve. To me it was a good way to spend some time and to don't throw an old thing, because it can stillbe useful.

Don't hesitate to post comments.
