Review on 💻 Rekidm USB Hub 3.0 with Extra Power Supply Port and Clamp Mount - Space-Saving, Durable and Adjustable Desktop USB Hub - Black by Roberto Cohen

This powered hub looks really nice with polished aluminum and is a great idea to mount. I also like that the power connector is a standard micro-USB rather than a random barrel-shaped connector. I found that it allows current back to the host port when powered, they didn't use a diode to make the current flow unidirectional. It doesn't supply enough current to reverse the Raspberry Pi 4, but it does pass some current, around 200-300mV. Luckily this can be fixed by opening it up and ripping off the +5V power connector on the back of the host connector. My only other complaint is that the powered version doesn't come in black.
