Pick a Bluetooth + 2.4GHz dual-mode board with 3000mAh+ battery: Bluetooth for multi-device desks, 2.4GHz for latency-sensitive use. The Keychron K2 Pro's 4000mAh cell runs weeks per charge in office duty.
Bluetooth multipoint (3 devices) covers laptop/tablet/phone switching without dongles.
2.4GHz dongle mode matters only for gaming; office typing is fine over BT.
Battery under 2000mAh means weekly charging; 4000mAh-class cells stretch to weeks.
Wired USB-C mode doubles as charging — prioritize boards that type while charging.
