Kingwin USB Hub 4 Port USB 3.0 Data Hub

I've slowly started adding things to my rig; I have utilized ports 1 & 3-7, skipping port 2. Why? idk lol, funny how things work out, huh? :) Here's the devices and their corresponding port numbers on the USB hub (photo attached). I wanted to list them so you can see that I'm running a pretty decent amount of seemingly power-hungry devices,in terms of running off a single USB 3.0 port to a 7-port USB hub. Full disclosure: All devices listed below are USB 2.0, with the possible exception of the thumb drive, it may be 3.0, it's unlabeled, but purchased in the last yr: [1] Samsung Android watch [2] **empty for now** [3] WiFi dongle [4] GPS dongle [5] BT dongle [6] Thumb drive [7] Logitech 9000 Webcam All devices appear in the Devices & Printers area of Windows 8.1 Pro AND WORK! The one thing I cannot attest to is the amount of power that it provides to whatever is plugged into it. This was never a concern for me, nor is one now. I have had the Samsung Android watch plugged in for about 30 mins now, started at 58% and it is now at 95%, so not bad on charging small devices! I'd also like to add that this USB hub came with a AC power supply for external power that I have not yet used, even after all of the above have been plugged in and working. I will end up using it, just to be sure all devices receive the proper mount of "juice", but in my initial testings.
