I ordered this powered USB hub because it delivers 2.5A per port at the same time no matter how many devices are connected. Most powerful hubs will not do this. This has reduced the cumulative load on my computer's USB. I liked it so much that I bought four of them, one of which I only use as a bedside charger.
