Keychron Q0 HE vs V0 Ultra NumpadHall Effect vs 8K Polling

The core difference is in their switch technology and build. The Q0 HE uses premium Gateron Double-Rail Magnetic (Hall Effect) switches in a full metal body, enabling features like adjustable actuation. The V0 Ultra uses standard mechanical Keychron Silk POM switches in a plastic body but offers a higher 8000Hz polling rate and much longer battery life.

The Keychron V0 Ultra advertises a significantly longer battery life. According to its specifications, it can last up to 360 hours with the backlight off, compared to the Q0 HE's advertised 56 hours. This makes the V0 Ultra better for users who want to charge less frequently.
