Cherry PIXIU75 81-Key Wireless Mechanical Keyboard

The Cherry PIXIU75 is an 81-key wireless mechanical gaming keyboard finished in black. It uses a tri-mode connection offering Bluetooth, 2.4 GHz wireless, and USB-C wired operation. The board features Cherry MX2A Red linear switches with a gasket-mounted structure and six layers of sound-absorbing material for a quieter typing feel. Double-shot PBT keycaps resist shine and provide a frosted texture. Per-key RGB backlighting covers 16.7 million colours.

Suited For Compact Wireless Setups.

This keyboard suits users who want a compact 75-per-cent layout with the flexibility to switch between three connection types without cables. The hot-swappable PCB allows switch changes without soldering, and the 4000 mAh battery delivers up to 220 hours of use while supporting charging during operation. Builders who need a dedicated wired-only keyboard with a fixed layout or a different switch feel out of the box should look elsewhere.

Tri-Mode Connectivity With 4000 mAh Battery

The single specification that decides fit is the tri-mode wireless system paired with a 4000 mAh battery rated for 220 hours. It lets the keyboard pair via Bluetooth or a 2.4 GHz receiver for cable-free desk setups, while the USB-C port provides a wired fallback and charging path. If your workflow demands a purely wired connection or a smaller battery footprint, this model will not match those requirements.

Questions about this item

Should I pick the 81-key layout or the 75% form factor?

They describe the same board — 81 keys in a compact 75% layout that keeps the function row and arrows while saving desk space.

What does the 220-hour battery figure mean in daily use?

The 4000mAh cell delivers up to 220 hours with lighting off; RGB backlight will reduce that, and you can charge via USB-C while typing.

How do the three connection modes differ in practice?

The 2.4 GHz dongle gives a low-latency wireless link, Bluetooth pairs with PCs, Macs, phones and tablets, and USB-C provides a wired fallback that also charges the battery.
