In this video, I do a deep dive on two USB hubs that look almost identical on paper: the Acer UH501 4-port hub (the bestseller) and the Anker 4-port USB hub. Both give you four extra USB-A ports from a single USB-A port, both hit up to 5Gbps, and both are slim, lightweight, and widely compatible (Windows, macOS, ChromeOS, Linux—even consoles like PS5 and Xbox). So if you’re expecting a “which is faster?” showdown, that’s not the real story. The real takeaway is power management—specifically the 900mA limit of a single USB port on your computer. The Anker is a simple, unpowered data hub and the packaging is clear: charging isn’t supported. That means all four ports share that 900mA budget, and if you overload it with power-hungry gear (like an external hard drive), you risk disconnects or even corrupted transfers. The Acer’s advantage is its dedicated USB-C 5V power input (power only, not data), which lets you bypass that limit for rock-solid stability when you’re moving big files or running higher-draw devices. I also compare their sustainability angles: Acer leans on certified recycled materials and verified carbon offsetting, while Anker emphasizes safer chemicals and cleaner manufacturing. Bottom line: pick Anker for low-power simplicity, and pick Acer if reliability under heavier workloads matters.
