I have recently bought a USB car charger from Halfords. Order No: 20578730. SKU: 275045. It will not charge my phone (Samsung Galaxy Ace) in the car with or without the engine running. The USB charger can supply more power than the phone needs to charge. I am using the lead supplied by Samsung which charges fine when plugged into the computer.
I've had the same problem. Although it has a 1 amp fuse (and the Galaxy Ace apparently needs no more than 0.7 amp) it seems this does not mean the charger is actually supplying that much.

Type S USB Charger Plug Converter
Convert your cigarette lighter into a USB port with the Type S USB power socket.
If i plug my phone into this, will it play my music from my phone out of the car speakers?
No, you would still need to connect from the phone into the stereo either by wire or wireless. The USB charger only connects effectively from car battery to phone, but not car stereo to phone.
