What will you mostly use it for?
The V3 Ultra is the clear choice for users needing a complete, standalone keyboard for gaming, office work, or programming due to its TKL layout and advanced firmware. The V0 Ultra wins for travel due to its minimal size and weight, and serves a specific role as a high-end numpad add-on. For content creation, the decision hinges on whether a numpad or media controls are more critical, or if using both together is an option.
Pick the Keychron V3 Ultra
- The V3 Ultra's TKL layout provides dedicated arrow and function keys crucial for game shortcuts and menus.
- Both offer the same 8000 Hz wireless polling rate for low latency.
- The V3 Ultra's larger 4000mAh battery supports longer wireless gaming sessions.

Keychron V0 Ultra Numpad vs V3 Ultra: your questions
No, the V0 Ultra is specifically a number pad. It lacks alphabetic keys, arrow keys, and a function row. It is designed to be used alongside a separate main keyboard, such as a 60% or 75% layout board.
The V3 Ultra has a significantly larger battery and longer runtime. According to Keychron, the V3 Ultra lasts up to 660 hours with the backlight off, while the V0 Ultra lasts up to 360 hours under the same conditions. The V3 uses a 4000mAh battery versus the V0's 1800mAh.
Yes. Both the Keychron V0 Ultra and V3 Ultra support an 8000 Hz polling rate in their 2.4 GHz wireless mode and in wired mode. This is a key shared feature for low-latency performance.
Both use ZMK firmware and are configurable via the web-based Keychron Launcher. However, the V3 Ultra's specifications also explicitly list support for QMK and VIA, which are popular open-source firmware options for advanced key remapping and macro creation.
Both keyboards come with OSA profile double-shot PBT keycaps and pre-lubed Keychron Silk POM switches (available in Red, Brown, or Banana tactile). They also share south-facing RGB LEDs and screw-in PCB stabilizers.
The V3 Ultra is generally more customizable. It supports QMK and VIA firmware, and its vendor description lists several foam layers for sound modification. While both are hot-swappable, the TKL layout offers more keys to modify and experiment with compared to a numpad.
Yes. The V0 Ultra includes keycaps for both Mac and Windows layouts and has system compatibility listed for macOS, Windows, and Linux. The V3 Ultra also includes this cross-platform support with a system toggle.
The V3 Ultra's vendor description highlights per-key RGB and Mix RGB features. Per-key RGB allows individual key color customization, while Mix RGB lets you create two separate lighting zones on the keyboard with different effects.
Yes. According to Keychron's descriptions, both the V0 and V3 Ultra support Bluetooth 5.3 and can connect to up to three devices for seamless switching between a computer, phone, and tablet.
Both the Keychron V0 Ultra and V3 Ultra use a gasket mount design with a polycarbonate (PC) plate. This design aims to reduce acoustic resonance and provide a softer, more flexible typing feel compared to tray-mounted boards.
The V0 Ultra is far more travel-friendly due to its small size (numpad only) and light 310g weight. It's ideal if you pair it with a separate compact keyboard. The V3 Ultra, as a full TKL, is larger and heavier at 960g, making it less convenient for frequent travel.
