81-Key 75% Wireless Gaming Keyboard

The Redragon K673 PRO is a compact mechanical keyboard built with a gasket-mounted structure and linear Redragon Red switches. It connects through USB-C wired, Bluetooth, and 2.4 GHz wireless modes, and includes a dedicated control knob for backlight and media functions.

Suits Users Who Want Tri-Mode Flexibility

Builders needing a full 104-key layout, dedicated macro column, or optical switches should consider other options. The 75% form factor omits the numeric keypad and function row, which limits spreadsheet and legacy shortcut workflows.

4000 mAh Battery Capacity

The integrated 4000 mAh battery powers the RGB backlighting and wireless link for extended sessions between charges. If your setup demands weeks of untethered use without any cable fallback, verify the runtime against your brightness habits before committing.

Questions about this item

What are the exact width and depth measurements of the K673 PRO keyboard in millimetres?

The board measures 104 mm wide by 335 mm deep, so verify your desk space or keyboard tray against those figures before ordering.

Which step do owners most often miss when switching the K673 PRO between USB-C, Bluetooth and 2.4 GHz modes?

Press the dedicated mode button to cycle through the three connections; the board does not auto-detect the active link, so skipping that press leaves you on the previous channel.

How do I replace the PO foam or silicone pads inside the K673 PRO when they wear out?

Remove the keycaps and switches with the included puller, unscrew the case halves, then lift out the 3.5 mm PO foam and bottom silicone pad for replacement.
