Review on 💻 Alxum USB 3.0 Extension Hub 4-Port with Power Port - Ideal for Desktop PC, MacBook, iMac Pro, Surface Pro, XPS, Flash Drive, Mobile HDD, Printer by Nigel Cohen

Looking at other reviews all I can say is temper your expectations here. It is a splitter and cannot charge 4 devices at the same speed as if one of them was connected to this port. There's no external power supply, so you're set to whatever voltage USB can handle. This hub can (and does not) boost the output voltage to charge multiple devices at the same rate as if only one were connected. I have connected Corsair USB wireless headphones, 2 Steam controllers and an Xbox controller. This and noticed 0 input lag compared to a direct USB 3.0 connection. As long as you understand that it can't increase voltage and therefore won't charge multiple times at the same rate as 1, it's worth every penny. DO NOT buy this if you are trying to charge multiple USB devices at the same time; ABSOLUTELY worth it if you're trying to expand 1 USB to 4 ports (for anything other than charging).
