The JBL Onstage Micro is supposed to disable recharging of the iPod when running off AAA batteries to avoid draining them, but sometimes this setting gets stuck even when the unit is plugged in through the AC adaptor. The workaround that I found is pulling out and reconnecting the iPod to the Onstage Micro (while both are powered on) and then unplugging and reconnecting the AC adaptor. Sometimes you have to repeat this process, but the iPod should start recharging after that. I tried it on the new 5th generation nano and this seems to work.

I can tell you that I have the on stage micro, bought this past winter. And it does charge my iPhone 3G. Works great, I love it.
