About month ago i found that my car cigarette lighter USB charger stop working…
After investigation and measuring voltages on output i found that problem is not in charger circuitry but in USB socket itself.
That charger was worth about 1 USD… Â but is it worth to repair?
I open charger, and check ebay (china sellers) to found same type USB socket.
I found 🙂 1 USD / 10 pcs with shipping included! I bought and pack all charger parts into ziploc bag for future repair.
After waiting time of 1 month , today my pack of 10 USB sockets arrived and i could start “repair”.
As You can see on last picture, my phone is very happy being charged 🙂
Repair took about 5 minutes
My conclusion:
I could order new one for 1 USD and put old to trash but instead of throwing out this 1 USD i got  10pcs USB sockets. I use one of this and i have 9 left in my “lab” for future experiments and of course working charger. 🙂 As You can see, sometimes it’s worth to fix something cheap 🙂
