My old Ipod recently failed (the flywheel stopped working and apparently that's not fixable), so I replaced it with a nano. I have many IHomes, "donuts," and car chargers that I used with my Ipod. Although the nano will play through the donuts and IHomes, it will not charge. Nor will it charge on my car charger. Is there any way to charge my Nano without sitting at my computer? Do I have to buy all new chargers, too? Are there special chargers for nanos? I am really disappointed that the Nano is not compatible with the other chargers.
