What is the best car charger for an iPhone?

[Sparky_92]

I bought one of these for around $5 on eBay.

The problem is that the iPhone makes a buzzing sound when charging. That's kinda annoying when answering phone calls or playing music when charging.

Can anyone recommend a good quality iPhone car charger?:confused:

The best one recommended is the one that is certified for it. Go to the apple or AT&T store and get the Griffin charger they sell there. Don't be cheap and buy a $5 charger that will detroy your $400 - $500 phone. That isnt worth it. It only cost $25. Its like buying a car you want but not being able to make the payments. At least if you get it from the AT&T store and something goes wrong with it while using the charger you have the receipt that you got it from them and they make help you out to replace the phone.

I got one of these Sony Xplod stereos (it even came with free installation). http://www.xplodsony.com/xplod/headunits/CDX-GT420U

I use the USB port to charge my iPhone and other USB devices.
