Frequently Asked Questions

Do the keyboard and mouse share one USB receiver?

Yes. One 2.4GHz USB receiver runs both the keyboard and the mouse, and it stores inside the mouse. You can use the two together or on their own.

Will this LeadsaiL combo work with a Mac or Chromebook?

Yes. It works with Windows 11/10/8/7, Mac OS, Chrome OS and Linux, on desktops, laptops, notebooks, Chromebooks, MacBooks and iMacs. It's plug-and-play with no software needed.

What batteries does it use and how long do they last?

The keyboard takes 1 AAA battery and the mouse takes 1 AA. LeadsaiL rates the set at up to 265 days of use, and both devices sleep after 10 minutes of inactivity to save power.

How far away can I sit from my computer?

The 2.4GHz connection is rated for up to 33 feet (10m) from the receiver, so you can use it across a desk or from a couch near a TV-connected PC.

Is the keyboard quiet, and does it have a number pad?

Yes on both. Soft membrane keys keep typing nearly silent, and the mouse uses silent micro-clicks. The full-size layout includes a numeric keypad and 12 FN multimedia shortcuts.
