USB charging in car

[geekboyuk]

Hello all - first thread I've created here!

I bought a USB adaptor for my car's cigar lighter recently so I can keep my phone topped up whilst out and about. It doesn't actually charge my i7500 though

The cable I use works to charge when connected to a PC - also the USB car adaptor works when charging other devices (eg, MP3 player).

Is there something else that I require to get it to work?
Have any of you managed to get in-car charging working?

Thanks!

The I7500 needs 5.0 Volts & 0.7 Amps to charge. Check the output of your car charger, if it doesn't match these input values, then you know what the problem is.

Thank you - I'll get a multimeter on it to check!

I got this one from Maplins which is rated 1A 5V.... hmmm.

You don't need a multimeter, just check the charger, it should have a label with input and output values. Check the output values.

Should be good enough. Try whether it will charge your mp3 player or something else, maybe the power supply thingy or the car power outlet is defective.

I'll have some time to tinker tomorrow - sounds like it's not a phone issue which is a good thing! Would be nice to be able to use my phone in my car for mapping and audio use.

Cheers!
