I bought a couple of these from BestBuy. The reason that I bought them, even though they were $40, was the fact that they included a separate +5V power supply, AND, they include a 2.4A charging port, that is ALSO a USB3.0 data port. So I can charge fast-charge devices (Cell Phones), AND transfer data.

My previous USB3.0 hubs, I was using a 10-port Orico, that was 7 USB3.0 data ports, and three charging ports, one of them 2.4A, the other two, 1.0A. That WAS useful, but it has been surpassed, mostly. It also didn't wear well, with ports dying and becoming "loose".

Also picked up some 7-port USB3.0 hubs from ebay, from a US seller, but they appear to be generic, and when I hooked one up to a friend's PC, and hooked up the +5V supply that came with it (it was only $12-13), it was BACK-FEEDING voltage into a POWERED-OFF (with the switch in back) PC. Not good. (This was the generic one from ebay, NOT the j5create one.)

Looks nice, but, for $40...
um, do I need it? no.
Do I want it? absolutely yes!
Data-transfer-stability wise, which one do you take, Orico or j5create?

Looks good, but you should be aware of a modest limit. Each USB3.0 port is supposed to be able to supply up to 0.9 A at 5 VDC to a connected device. This Hub CAN be used when only Bus-powered - that is, its only power cource is the host computer's USB3.0 port which can supply that 0.9 A max current, but then that must be shared among all the Hub's output ports. The Hub is also well designed because it includes a separate power supply module able to replace the power from the host port. This module can deliver the 5 VDC supply at up to 4.0 A total. But you ned to realize that this only is enough for 4½ output ports' max current limit, so you can not use the max current from every one of its ports simultaneously. And of colurse, IF you are using the max current draw of 2.4 A from the fast-charge port, the other six ports can only access 1.6 A total to share. MANY such hubs are dsigned this way, assuming that in the real world nobody will actually try to use the max power from all of the ports simultaneously. In fact, some devices like keyboards and mice use small currents. It's the big draws like laptop portable hard drives that need max curent.
