USB Cellphone Charger Cable
I have a recently moved to the US, but my cellphone charger has a British plug. Therefore I have use an adapter, which makes the whole thing very cumbersome to carry around. As I always have some USB outlet like my laptop around anyways, I got the idea to make a USB version for charging the phone.
Check the Power Adapter Voltage
Check what voltage the power adapter generates. For my Samsung model it is 5V DC, which is just what we want.
Cut the Cables
Check Voltages
Soldering
The little black insulating pieces are heat shrinkable tubing, which is very convenient. Just don't forget to put it on there.
Charge Phone
Hooray, it works!
