Review on 🔌 Wavlink 4 Port USB 3.0 Hub with Power Switches and LEDs: High-Speed Data Transfer for Mac, Laptop, Ultrabook, and Tablet PC by John Fuentes

I bought this hub to connect 4 low power monitors to my laptop via USB 3.0 -> HDMI adapter cables. Unfortunately, the hub cannot power more than 1 device at a time without an external power supply (which does not come with the hub). Now I have to order a $13 power adapter that comes bundled with the hub, which added to my overall cost (not happy with that extra cost, nor the extra wait for the adapter to ship). If I had known that the adapter costs extra and has to be purchased in advance, I wouldn't mind. My biggest annoyance is that the power supply was supposed to come with the hub and I didn't have to troubleshoot the setup to identify and fix the power supply issue. Since I had to purchase an additional item to make this work for my purposes, I gave it a 1 star rating because it's useless to me without a power adapter.
