Homemade USB Charger for Nokia

Once, I had to bypass a dozen stores in search of Nokia CA-100 (USB-charger for a cell phone). To my great surprise, there was no such device in any such device, so I decided to solder the charging myself.


So, we take:

• Non-working charger for Nokia, (If this was not at hand was - buy the cheapest);
• A piece of USB cable with A-plug;
• Soldering iron;
• Solder;
• Insulating tape;
• Scissors.

Take the scissors and cut off the plug from the charger, leaving a few centimeters of cable.
We do the same with the USB cable.
We remove approximately 0.5 centimeters of total insulation from the cables. For the USB cable, leave only black and red wiring, all the rest neatly cut, we clean the remaining wiring.
It should turn out like this:

Now it remains only to solder the wiring in pairs: "red-red" and "black-black", roll each solder separately, and then between each other with tape.

Result:

Work takes 15-20 minutes, the cost of raw materials (charger and USB-cable) does not exceed 300 rubles. The cost of such a charger in online stores is 900r-1000r.

Disadvantages:

• Charging takes 15% - 20% more time than from the network, since only the voltage is the same, and the current is less;
• 15% - 20% less charge;
