The HP 725 Multi-Device Rechargeable Wireless Keyboard (HP part 9T5B2AA) is a full-size, low-profile wireless keyboard for office and home work across several devices. It connects either through a USB receiver or Bluetooth and can pair with multiple devices, switching between a PC, laptop or tablet. Instead of disposable batteries it uses supercapacitor technology that HP says charges very quickly over USB-C, with a usage life of up to about two months per charge depending on use; a USB-C to USB-A adapter cable is included. The layout includes a numeric keypad, multimedia keys, a Copilot key and programmable hot keys that can be customised with HP Accessory Center software, and the keys are quiet and rated for 10 million keystrokes. HP lists dimensions of 420.5 x 120.7 x 17.7 mm and a weight of 499 g. It supports Windows 10 and 11, macOS and ChromeOS, and needs a USB-A port for the receiver or Bluetooth. The keyboard is black with grey accents, uses at least 60% post-consumer recycled plastic and comes in FSC-certified packaging. No mouse is included. It suits office desks, home workstations and multi-device users.
