1000Hz polling rate We use Nordic's NRF52810 SoC and STM32F072 MCU to make the Air96 V2 Wireless Mechanical Keyboard polling rate up to 1000HZ, which will reduce the latency of the keyboard in wireless mode. It also gives us a great gaming and office experience in wireless mode! 4000mAh BatteryAir96 V2 is equipped with a 4000mAh battery, you can enjoy 35~120 hours of gaming time on a single charge (with the keyboard backlight on), and if you turn off the keyboard backlight during use, the usage time will reach 220 hours, and the LED light bar on the side of the keyboard will also show the keyboard power at any time (the above data is the result of lab tests)
