Might also want to take a look at the XtremeMac dual usb charger: http://www.xtrememac.com/en-US/products/chargers/InCharge-Series-for-iPad/universal-dual-usb-wall-charger/
The only one I've found that can charge two iPads (or an iPhone and an iPad) simultaneously. Be curious how they rate in your tests.
[ Disclosure: no association with them other than a happy user. ]
