Compact 75% Layout

The Vszerda F75 is a 75% wireless mechanical gaming keyboard with an integrated control knob and 81 keys. It targets gamers and typists who want a smaller footprint than a full-size board while keeping dedicated function and navigation clusters. Pre-lubed linear switches and side-printed PBT keycaps deliver a creamy sound profile and smooth travel out of the box. The hot-swappable PCB accepts both 3-pin and 5-pin switches for easy customisation without soldering.

Tri-Mode Connectivity

Bluetooth 5.0, 2.4 GHz wireless and USB-C wired modes let the keyboard pair with up to five devices and switch between them via shortcut keys or the side button. A 4000 mAh rechargeable battery powers extended wireless sessions, while the 1.8 m cable provides a wired fallback for charging or latency-sensitive play. The layout is ambidextrous and compatible with Windows, macOS, iOS, Android, PS4, PS5 and Xbox systems.

Advanced Structure Under Load

An extended silicone pad, PCB single-key slotting and five layers of internal filling absorb cavity resonance and stabilise each keystroke during long gaming or typing marathons. Sixteen RGB lighting modes with 16.8 million colours are adjustable on-board or via software. Switches are rated for 60 million actuations, and the board weighs 1023 g for a planted feel on the desk.

Questions about this item

How long does the 4000mAh battery last under continuous all-day use?

The keyboard draws 830mA at 3.7V, so the 4000mAh cell provides roughly 4.8 hours of non-stop illumination before needing a recharge.

How loud is the keyboard when typing for hours at a time?

Pre-lubed linear switches, five silencing layers and a gasket-mounted PCB keep the sound to a low creamy thock even during extended sessions.

What devices and cables are required to use every connection mode?

You need a USB-C port for wired mode, a free USB-A slot for the 2.4GHz dongle, and Bluetooth 5.0 on the host for wireless pairing.
