Amazon also has the new Magic Mouse 2, which improves on the original Magic Mouse by having a built-in rechargeable battery (and you charge it using the included Lightning cable, same kind your iPhone uses– and two minutes of charging gives 9 hours of use!). The Magic Mouse 2 is also a little lighter and it glides a little more smoothly than the original. Note: you’ll need macOS 10.11 or higher to use all its features.

If you need a wireless, rechargeable keyboard, Apple’s Magic Keyboard fits the bill. It recharges with a Lightning cable (included) so you’ll never need to replace batteries.
