With disappointment, I realized that the old power supply, which still uses the Firewire cable, the new iPod touch will not charge. The Touch recognizes Although seemingly that a charging cable is plugged in - at least the symbol "plug = power" disappears, indicating that the touch when it is completely empty, but it is not loaded.
So I put myself on the search for a new power supply and opted for the "Belkin USB AC adapter DUO for iPod and iPhone". It exists here at Amazon in two versions, one of these here without additional cables and once for roughly 5 more, including USB-to-dock connector and USB-to-mini-USB cable. I opted for the version without cable, USB-to-dock connector cable I already have two (after all, does the cable from my old iPod to the new iPod touch), and front USB-to-mini-USB cable can you look now so swamped.
The case makes a solid impression and touches her quite well, you do not have to keep feeling a cheap product in hand. Problems when plugging into the wall socket, as you read it here at some other products in the reviews, I can not determine.
The iPod touch was as expected loaded immediately after insertion, the corresponding lightning symbol when battery appeared and he made the characteristic Ladegeräuch. Since I had read here in reviews on other products that some power supplies the iPod briefly invite, but then the iPod suddenly no longer recognize the power supply, I have left the touch all night at Belkin. Result: Even in the morning nor the Touch has the Belkin recognized as a power supply.
As "Duo" device I could at the same time easily connect my TomTom navigation device and load. However, it does not load PS3 controller, but not what I had expected.
I have found no noise on the power supply (pipes or the like), and no excessive heat build-up.
Conclusion: As a power supply for iPod touch 4G and another loadable via USB device highly recommended.
