In short, you can plug the four-port charger into an electrical outlet, attach a Samsung Galaxy S III’s to the charger via its USB cables, and the Galaxy S III phone will recharge at nearly the same rate as if it was plugged directly into an electrical socket.
This works because the Samsung Galaxy S III supports the USB battery charging specification (aka BC 1.1/1.2). Following the battery charging spec means that customers can get a predictable result for recharging when the Galaxy S III is plugged it into a USB hub that also supports the charging spec. The Plugable four-port hub and fast charger is such a hub. Plugable’s 10-port and seven-port hubs don’t support battery charging even though they do have their own power adapters.
Anyone who’s ever tried to recharge a phone or tablet computer just by plugging it into a standard USB 2.0 hub knows that results aren’t often positive. Yes, sometimes it seems to work, but it’s almost by accident. In general we can’t guarantee the desired results when either the device or the hub don’t comply with BC 1.1/1.2.
With the Samsung Galaxy S III, we can say unequivocally from our own testing that it will recharge when plugged into Plugable four-port hub and fast charger. We hope the Galaxy S III is in the forefront of a wave of devices that support the battery charging spec. But for now, the Galaxy S III’s support of the spec is another plus for a phone that’s already winning rave reviews.
