WE DON'T HAVE enought USB Cables when trying to charge our stuff so it's handy to have a PowerDock 5 around to slot things in for a boost.
The Griffin PowerDock 5 has enough room to give each tablet its own charging port along with a clear backrest. You can keep an iPad in its case while recahrging too. An illuminated status light tells when PowerDock 5 is powered up and ready to charge up to 2.1 amps per recharging slot. We have 16 iPads running in one trolley so it's handy to know there's a rack that can recharge five in one go. Since this device exposes generic USB ports along one side, it can be used with any hardware capable of charging over USB.
And the 2.1 amps per connection means it will recharge iPads and Motorola Xoom tablets without a low power warning.
The PowerDock 5 costs $99 online.
