As indicated by its name, a wireless mouse doesn’t require a wired connection to work. It looks and works very similarly to a wired mouse but doesn’t use any cable to connect to the host device. Instead, it uses wireless technology—typically, either Bluetooth or a proprietary protocol similar to Wi-Fi.

As a result, it’s easier to carry while traveling and allows the control of the interface without requiring proximity to the device or limiting movement by the length of a wire.

A mouse with a custom wireless protocol always needs a proprietary connector to work. In contrast, Bluetooth-based models can usually connect to any Bluetooth receiver, including your laptop’s built-in one.

Unlike wired mice that get power from the host device, wireless mice are powered either by rechargeable built-in lithium-ion batteries or AA or AAA batteries. In addition, they may include a charging cable that temporarily turns the mouse into a wired one.
