What will you mostly use it for?
The V0 Ultra is the more compelling fit for gaming and travel if its higher polling rate or larger battery is a priority. It also has an edge for office use with its gasket-mounted construction and larger battery. The K0 Max better suits users who specifically want a low-profile numpad with QMK and low-profile switch compatibility. For customization, the choice depends on whether you prefer QMK and low-profile switches or the V0 Ultra’s listed MX-style hot-swap support.
Pick the Keychron V0 Ultra Numpad
- The V0 Ultra lists an 8000 Hz polling rate, compared with 1000 Hz for the K0 Max.
- The V0 Ultra has a gasket mount and polycarbonate plate, which Keychron describes as reducing resonance and adding flexibility.

Keychron K0 Max Numpad vs V0 Ultra Numpad: your questions
The K0 Max is a low-profile numpad with QMK support and a listed 1000 Hz polling rate. The V0 Ultra has a gasket mount, an 1800 mAh battery, and an 8000 Hz polling rate in wired and 2.4 GHz modes.
The V0 Ultra lists an 8000 Hz polling rate, while the K0 Max lists 1000 Hz. Keychron specifies that the V0 Ultra reaches 8000 Hz in wired and 2.4 GHz modes.
Yes, QMK support is listed for the K0 Max. Its vendor description also names Keychron Launcher as a programming option.
The K0 Max compatibility notes specify low-profile switches and keycaps only, so standard MX keycaps will not fit. Its vendor description identifies its included keycaps as low-profile Double Shot PBT.
The V0 Ultra has an 1800 mAh battery, compared with 750 mAh for the K0 Max. Keychron also describes the V0 Ultra as offering up to 360 hours with the backlight off, while actual use can vary.
Both list Bluetooth, 2.4 GHz, and wired connectivity. Keychron identifies Bluetooth 5.2 for the K0 Max and Bluetooth 5.3 for the V0 Ultra.
The K0 Max is explicitly a low-profile numpad, and its vendor description names Gateron and Keychron low-profile switches as compatible. The V0 Ultra vendor describes hot-swap support for many 3-pin and 5-pin MX-style switches instead.
The V0 Ultra uses a gasket mount with a polycarbonate plate. Keychron says this design reduces acoustic resonance and provides a softer typing experience.
Both models list RGB lighting, but they use different LED orientations. The K0 Max is north-facing, while the V0 Ultra is south-facing and its compatibility notes warn that shine-through legends stay dark.
The V0 Ultra is listed at 310 g and measures 29 x 118 x 139 mm. A weight for the K0 Max is not listed here, so the available specifications do not establish which one weighs less.
