Wireless keyboard and mouse combo

The LeadsaiL K786-BLACK pairs a full-size 108-key keyboard with an ambidextrous optical mouse using a single 2.4 GHz USB receiver stored in the mouse. Plug-and-play operation works with Windows laptops and PCs, delivering up to 33 feet of lag-free range for home or office desks.

Replaces separate wired keyboard and mouse sets

The combo removes cable clutter and frees a second USB port because both devices share one receiver. Twelve FN multimedia shortcuts add one-touch media, volume and email control that basic wired keyboards lack. The jump is worth it when you want silent membrane keys, 1600 DPI tracking and 265-day battery life from one AAA and one AA cell without installing software.

Check your setup before ordering

Verify the host has an available USB-A port for the receiver and runs a compatible Windows operating system. Confirm you can supply one AAA battery for the keyboard and one AA battery for the mouse, as neither is rechargeable. Ensure desk space accommodates the keyboard footprint of 43 by 12.8 centimetres and that a 2 mm thick mousepad suits your surface preference.
