For adventure riding I found I needed a USB charger to charge my iPhone and iPod. The problem I had was the USB charger that plugged into my car charger socket on the bike would vibrate loose as I rode. I decided to go to a powerlet socket which clips the plug in place to stop it working loose.
Now I had no way of plugging powerlet to USB so I thought I’d make an adaptor lead. This lead can be made any length and I thought it could be handy to run from the bike to my tent to charge accessories if it was raining. ( the plug can be powerlet or car charger whichever you prefer.
First I bought a USB car charger


Then I opened it up

And took out the circuit board

I then removed the positive and negative connections by heating their solder join with a soldering iron and pulling them out


Next I soldered a new lead onto the board in place of the old wires. Make sure positive is on the centre pin.

Now reassemble the plug

Now strip the other end of the lead and fit your plug of choice ( mine is a powerlet ) be sure positive is on the centre pin.

Assemble your plug and test
