Keychron Unveils K4 & K10 Ultra 8K Keyboards with Numpad and 600-Hour Battery Life
Keychron has officially expanded its K Ultra 8K series with two new models, the K4 and K10, catering to users who prefer layouts with a numeric keypad. The K4 features a 96% compact full-size layout, while the K10 offers a traditional 100% full-size layout. Both new keyboards are priced at $114.99.
A standout feature of the K4 and K10 Ultra 8K is their high-performance connectivity. Both models support tri-mode connections and boast a remarkable 8kHz polling rate, ensuring ultra-low latency for competitive gaming and professional use. This advanced performance is powered by ZMK firmware, which is known for its efficiency and customization capabilities.
Perhaps the most impressive specification is the battery life. Despite the high 8kHz polling rate, Keychron claims these keyboards can last up to 600 hours on a single charge from their built-in 4000mAh battery. This combination of extreme performance and extended endurance sets a new standard for wireless mechanical keyboards.
In terms of construction, the K4 and K10 feature an ABS plastic case. Internally, they are packed with a 6-layer damping and filling structure to enhance the typing sound and feel. The keyboards are built on a steel positioning plate, include a hot-swappable PCB for easy switch customization, and come with integrated RGB backlighting.
For the typing experience, these keyboards are equipped with Keychron's own Apex series mechanical switches. These switches feature a transparent PC top housing and a walled POM stem for stability. Users can choose from Red (linear), Brown (light tactile), or Banana (early tactile) switch variants. Topping them off are high-quality OSA profile keycaps made from durable PBT plastic with a double-shot injection molding process.
Keychron K4 and K10 Ultra 8K keyboards successfully bring high-end performance features to users who require a numeric keypad. With their blistering 8kHz polling rate, legendary 600-hour battery life, and rock-solid build, these powerhouses are a must-add to any Heyup user's wishlist—delivering the ultimate full-sized setup upgrade for gamers and professionals alike.
