2 Port USB Car Cigarette Lighter Adapter Dual Plug for iPod MP3 Players Charger - Color White

Pros:
Very good quality and works great to charge my ipod and plug in my fm transmitter. Very good price.

Cons:
Can't do the two at the same time without the annoying hum due to the ground loop.

Overall: Definitely worth it.

It worked great until it started falling apart repeatedly (it only took a couple of months of very rare use), and eventually it was responsible for a blown fuse in the car. At this point I'm not sure I want to risk using it, for the sake of the electronics, and the car.

This does just what you think it would and is of a better quality construction than what I expected for the price. I don't think I'll need another one of these for a while but when I do, I won't hesitate to buy this again.
