Kensington Car Charger for iPod and iPhone 1G, 3G (Black)

Not the cheapest iPhone charger out there, but it is well made and the USB cable plugs in solidly. As others have mentioned, you can charge any USB device with this as well while on the go. Nice long cable, you could likely keep this plugged in and talk while *safely parked on the side of the road* :). Highly recommended.

Simple and inexpensive, providing a powered USB port you can use to charge anything. If the blue light bothers you, rotate it while plugged in and you can't even see it, or put a piece of tape over it :p

Enjoy!

I purchased two last month and have encountered zero issues with them. The removable dock cable is very nice, and it will charge/power other USB devices. It's compatible with Apple iPod nano (1st, 2nd and 3rd generation); iPod (4th and 5th generation); iPod classic; iPod touch; iPhone; iPhone 3G.
