Car charger for iPod touch

When the Touch changed from 1st to 2nd generation, the charging circuit for all iPods from that point on changed to a different pin on the dock connector. You'll need to get a new charger for your Touch, or look for an adapter cable to allow you to use your old charger.

Let me say it another way then ...

The dock connector on the bottom of your Touch remained the same as your other iPod, but the internal connections changed such that the DC voltage needed to charge the iPod has to be applied to a different pin on the dock connector. The chargers that you have will fit the Touch, but they will not charge it because they are not applying the voltage to the right pin on the connector. The adapter I mentioned transfers the supplied DC to the correct pin on the dock connector, thus it would sit between your Touch and the existing charging accessories that you have.

Sorry, I missed that you're trying to use the stock iPod cable. I thought your accessories had an "iPod connector" on them and they were being plugged directly into the iPod -- those types of accessoreis can cause a compatibility problem as I was mentioning.

The stock iPod cable should work fine if it is connected to a USB source that can provide power. If you're plugging the stock iPod cable into a USB port, perhaps the source on the USB side is not functioning or does not provide enough current?

If the USB port you're plugging into is charging the DS then there is DC present, but trying to test the current limit is not an easy thing to do. Perhaps you have a defective iPod cable? Have you tried using the exact same cable to charge your iPod on your computer?

Very strange, I would think it would work if there is DC present, but perhaps the Touch now requires a special authentication chip in the charger.

If you still have your old iPod video, would you be able to charge it with these DC adapters? If they can charge your old iPod but not your Touch, did they ever work with your Touch, or is this a new Touch that you're just starting to use? Also, did you recently update the Touch's OS? Just curious if 4.0 could have enabled something that causes the Touch to look for an authentication chip.

I got 3 differents car chargers but none charge my iPod Touch so went to the apple store and the guy says this new gen of Ipods need more power so I purchase another car charger (now i got 4), is a Griffin car charger an it works Ok..! charges and play the iPod to the car radio.
