EDIT: just re-read what it says.... 'automatically' sync when plugged into power, so it's not saying 'only' when plugged in, but rather you can do it manually whilst on battery power, not automatically.
I just figured it out. Plug your Ipad into your system and in the Summary tab of your device, go to Options and check the box "Sync with this Ipad over wi-fi". Click apply and then unplug the ipad and shut down iTunes. Plug the device into the power unit and start iTunes. Give it a few seconds then you should see the Sync Now button working. If you leave it alone for ab bit, it will sync on it's own.

The sole difference is that now it doesn't sync until I load iTunes and tell it to, which I actually prefer. The improvement needed for auto-sync is a scheduler, rather than the iPad simply trying to load iTunes and sync all the time, regardless of what I'm doing.

With the device connected via usb, in iTunes, on the Summary tab make sure the box "Open iTunes when this iPad (iPhone) is connected" is unchecked. If the box is checked, uncheck it and click the Apply button. Close iTunes, turn off the device and then open iTunes and turn the device on.
Hope it works for you. Be sure to do this for each device.
