I create topic in Apple Community website

Hello,
I am sorry, you cannot use this accessory to charge iPod classic (2nd or 3rd generation). iPod classic (2nd generation) still used a FireWire connector. iPod classic (3rd generation) (the device in the photo you supplied) used a special 30pin dock connector that split off into a FireWire 400 and USB connector. FireWire was used to supply power to the iPod while USB was used to transfer data. This car accessory supplies power over the USB bus into the 30-pin Dock connector which not only won’t charge this iPod, it will damage the iPod.
While this charger uses the 12V car outlet, it still transfers power over the USB bus. The USB technology is just integrated within the power adapter and does not present itself as the typical USB form factor.
Similar to how the FaceTime camera integrated into a MacBook would operate. To the system, the camera is just a typical USB camera however there is no user accessible USB port to connect this camera. It is the same concept with this car charger.
