In this video I unbox and test the 3inuS x Whatgeek Keybo Hub E01 5-in-1 mechanical keyboard, and it honestly has one of the most useful features I’ve seen in a wired board: a built-in powered 5-port hub. I walk through what you get in the box (extra red switches, keycap puller, switch puller, and bonus keycaps), then I set it up and show how it switches between Mac and Windows mode with a couple of button presses. It’s an 87-key compact layout (no numpad), heavy and thick with solid materials, and it looks clean with the light gray/pastel colorway and teal accent caps. The big highlight is the hub on the back: three USB-A, one USB-C, and even HDMI 2.0 that can do up to 4K 60Hz. I explain what that means for charging, data transfer, and why a stable wired connection can be a productivity boost if you’re always hunting for ports behind your PC. I also pull the caps to show the double-shot shine-through keycaps, talk hot-swap compatibility, and do a sound test—because these red switches are fast, but they’re not exactly “silent night gaming” friendly. My main critique is the power interface: it can take up two USB-C ports, and I’d love a future redesign that runs everything through one detachable USB-C cable.
