Looking for a USB 3.0 extender or hub possibly, not sure which

Look for a Hub that really does say it is for USB3 particularly. PLUS, make sure it comes with its own power supply module. Every USB3 port should be able to supply up to 0.9 amps at 5 VDC to its device. A Hub with no power adapter can only get that much from its host's port and then attempt to share it out to ALL of its attached devices, which usually is not enough. With its own adapter plugged in, it gets power for all its attached devices from that adapter, not from the host port.

Now, it's a bit tricky checking the capacity of these things. Some Hubs are supplied with adapters that are a bit too small for the number of ports they have, although you normally do not need that full power for ALL of the Hub ports at the same time. But what's tricky is that the adapter supplied often provides the Hub with 12 VDC, and the Hub converts that down to 5 VDC. So you have to check for the WATTS rating of the supplied adapter, not the volts and amps. Now, 0.9 amps at 5 VDC is 4.5W of power, and you need that for EACH Hub port (well, maybe not all of that). So if you get a Hub that has 6 ports for USB3 devices, you need almost 27 W from the power adapter. (If the adapter's spec's do not include Watts, then calculate Watts as just it output Volts times its Amps ratings.) In practice, most often a 6-port Hub can do OK with 20 to 26 W from its included power adapter.

Watch out for another power stumbling spot. Many USB3 Hubs with several ports advertise that some of them are special high-power "Charging" ports for things like phones. They do work, BUT those ports require MORE power than a "normal" USB3 port, so the power adapter supplied needs to be capable of supplying that IF you plan to make use of those special charging functions.

Don't forget that the cable from your computer's USB3 port on the back to the Hub's input connector MUST be USB3 in order for you to achieve the proper speed. Likewise, any USB3 device you plug into the port requires using a USB3 cable.

As an example, if you want both data ports and special charging ports, this unit by Vantek

has 4 standard USB3 ports for data devices plus three dedicated charging ports able to supply higher currents. It includes it own power supply module cable to supply 60 W (12 V at 5 A) to the Hub, more that the total output rating of all its ports a maximum use.

If you need only USB data device ports and no special charging ports, there are other devices.
