Griffin Multidock
I have 30 iPads for my classes in Tokyo. We are waiting for the
Griffin Multidock to clear the electric safety regulations, but should get 3 in the next week. It covers 4 functions: 1) Charging, 2) Synching, 3) Storage, 4) Security
Honestly, we don't need the security and we could synch over our wireless network. Paying $70 per iPad just to charge is expensive. We considered just having lots of the standard USB connected to extension cords, but that gets unwieldy. And the storage, keeping them so the screens don't get scratched, is another consideration. There is a high-powered
16-USB charger (you need high power, 10 watts, so most multiple USB chargers don't really work). This one is more than half the price of a multidock (per iPad).
The Multidocks you can daisy chain up to 3 so I can synch all 30 of my iPads at once. At least according to the literature.
Will send an update after the the Multidocks arrive. If you are in the US, you can get them now.
