Due to a lack of ports on my laptop I bought this USB hub from Revain. This product can expand USB A port to 1 USB 3.0 port and 2 USB 2.0 ports, which can basically meet my daily needs. I'm mainly talking about my experience with this USB hub. Pros: Because this USB hub is very small, just the size of my finger, it doesn't take up space at all and it's very convenient to carry. I found that USB 3.0 transfer rate is much faster than USB 2.0 transfer rate. A mouse, keyboard, wireless Bluetooth adapter and mobile phone can be connected and used normally after being connected to this USB port. NO connection failed. Since this USB hub doesn't draw power, I don't usually turn it off. other drivers or software. It's very easy to use. If you find that there are not enough ports and you need multiple USB ports, I think this product is very suitable. Cons: Because this USB extender is for data transfer and expansion ports. If you want to use this product to charge your phone, I don't recommend you to buy this small USB hub. This USB port supports charging, but the charging speed is very slow. I connect it to my laptop and then connect it to my phone to charge it. It takes a whole day to fully charge your phone. So if you just want to buy this USB port expansion hub, I recommend you buy this product.
