Thanks for the link. Have you tried it?
Bought it , doesn't work.... very annoyed but caveat emptor. When its in sync mode, it will both sync and charge, when its in charge mode it doesn't do anything. I've tried every order and combination of plugging and unplugging and its still useless. Second edit: With a different mini-usb cable, the stock APC cable that came with the universal battery, it will charge. Mysteries abound as the APC cable will also datasync, but I'm not going to question the great techno-loa that have blessed me with a working pair of external batteries.
