RSHTECH Powered USB Hub, 4 Port USB 3.0 Hub Splitter Portable Aluminum USB Data Hub Expander with Individual On/Off Switch and Universal 5V AC Adapter, 3.3ft USB 3.0 Cable (RSH-516)

I have a security NVR and look at the recordings in another room. There are two USB mice connected and I was having trouble with one of them. It was probably because of the length of one of the mice USB cords(40 ft). It worked for months but then the trouble started when I would click the mouse. When I installed this unit it started to work SO FAR. Only had this unit a few days but lets hope it continues to work.

Excellent USB hub/port.

Works as promised.

Even when plugged in, this device couldnt carry a signal for high-end audio equipment.

Works well, easy to use

Bought this in an attempt to get my computer (with a cheap power supply) to stop disconnecting my USB devices when it gets too hot and so far its worked a treat. No connectivity problems in general, though, and I dont regret the purchase in the slightest.

Works perfectly with all of my accessories with zero issues. Have monitor, wireless mouse and keyboard connected to it and they all work as if they were connected directly to the computer.

Perfect for what I am using it for. Very happy with the device.

This USB hub is not a good purchase. It worked well for a week and ever since, out of four inputs, one or two will work. Do not buy. Mine is gathering dust on a shelf.

With the limited usb support for single board computers like the Raspberry Pi 3 or 4 This device really comes in handy. Having it powered makes it so i can run multiple external hard drives with out issues. The pi alone can handle that. But then you take up valued usb ports. Especially usb3 ports which the pi only has 2. Plus depending on were you place your pi having a usb hub makes plugging in flash drives peripherals and so on much easier.
