I bought this car charger after it was recommended on this forum: HDMI Cable, Home Theater Accessories, HDMI Products, Cables, Adapters, Video/Audio Switch, Networking, USB, Firewire, Printer Toner, and more! When using it, the charger gets hot and I get the slight sense of burning rubber when I smell the charger up close. Maybe it just smells like this because the rubber is new? I felt the usb cord leading to the phone and it is cool and the phone acts totally normal when I use it plugged in. By the way, this is my first post. I've been a lurker for a while. This forum is awesome, really saved me a lot of headache! Thank you!
