I've been looking at these on Samsung's site. I've noticed it can be a bit confusing distinguishing which is which.
Galaxy Note? II Smart Dock EDD-S20JWEGSTA $99.99
Dock with a 2 Amp (2000mAh) USB Travel Charger
Samsung Galaxy Universal Multimedia Desktop Dock EDD-D200BEGSTA $49.99
Dock with a 700mAh Travel Adapter
Galaxy Note? II Spare Battery Charging System EB-H1J9VMAGSTA $49.99
Stand (NOT a dock!) 3100 mAh Standard Battery, 700mAh Travel Adapter
(All the above is from the Samsung site. If there are any errors, please post a correction!)
Note that the first two are docks, but the third is a stand - it will not charge the battery in the phone, only the spare inside the charger. But what's really important is that the Smart Dock is the only one that comes with the 2A charger. Expect much slower charging from the others.
The supplied (in the box with the phone) AC adapter is 2 amps, you can use that with Universal dock instead of the 700 mAh charger. I was unable to find a 2A charger on the Samsung site, but they do list a 1A travel charger.
So instead of getting one of these I'll most likely just get a $10-20 clone dock and use the charger that comes with the phone with it. I really wanted two of the fast chargers but I have no use for the multimedia dock.
