The Zune 80 seems to need a full 1000 mA, though because it works with every USB port I've tried it on, I'm sure it's still within the USB spec. This isn't something I know very much about though. :wink: |
I wondered about this part of the comments too. If the 80 charges from a USB port, it is charging from a 500mA source. Should work fine from either a 700mA or a 1A source. Now, the kicker is, many devices seem to know if they are connected to a real USB port or not. Does the 80 not even show it is charging when hooked to the Proporta? I have some things that are greedier when hooked to what it believes is a charger. Gomadic seems to have this issue covered with different connectors depending on if you want to sync/charge(USB port), as opposed to just charge. Don't have a Zune 80, but have definately seen the difference between the two tip types when trying to charge greedy devices like the JasJar and Axim X50v.
You ought to see if you can hit up Gomadic for some Zune tips and a cable to try with your chargers.
P.S. I picked up one of the APC UPB10's too. Nice little unit.
