I love the idea of the product being so versatile. However, I encountered a similar problem with the iPod charger as other customers. It won't charge the iPod. The cord for the iPod works when connecting the iPod touch to the computer (so you know that the cord works), and the car charger component works with the other cords for the other devices (so you know that the car charger works), but the iPod cord and car charger will not work together. I figure that it is worth keeping because it charges our GPS (Garmin Nuvi) and Nintendo DS. All the components separately would cost approximately the same, so it is still a fairly good deal. I like that the cords are retractable and that the car charger has the additional12V DV, leaving it open for other devices. If you are interested in purchasing this product to charge an iPod, I would not recommend it, but it works well with other devices.
My ipod won't work with the cassette adapter that I ordered when it is plugged into this charger - which makes the reason for this charger moot. I also tried to plug the ipod into the charger, and it didn't charge the ipod, period. I would return the charger if I still had the packaging.
This product has come in very handy and is so easy to use! The retractable cords are very useful. I do wish that there were an adaptor for the Gameboy Advance systems as my children still have a couple of those also. Overall a great product!
