The Apple Magic Mouse (USB-C version) is a sleek, minimalist multi-touch wireless mouse built for Mac users. It offers smooth gesture support, Bluetooth connectivity and a built-in rechargeable battery — a great choice if you prefer a clean desk setup and full compatibility with macOS and iPadOS. General Name: Magic Mouse (USB-C) — part of Apple’s pointing-device lineup. Wireless connectivity: Bluetooth. Rechargeable battery: built-in, no disposable AA cells. Charging / port: USB-C port (bottom of mouse) for pairing and charging. Compatibility: Requires a Mac with macOS 15.1 or later, or an iPad with iPadOS 18.1 or later. Size & Weight Height: ~0.85 inch (2.16 cm) Width: ~2.25 inch (5.71 cm) Depth: ~4.47 inch (11.35 cm) Weight: ~0.22 pound (0.099 kg) (varies slightly by manufacturing) Features Multi-Touch surface: supports gestures such as swiping between pages, scrolling through documents, zooming. Glide / foot design: optimized for smooth movement across desktop surfaces. Rechargeable battery life: about a month or more between charges (typical use) per Apple spec. Used Condition ConsiderationsSince you’re specifying a used unit: Check for wear on the bottom feet / skates — these degrade and affect glide. Verify battery capacity / health (rechargeable batteries age). Confirm the port is functioning (USB-C) and Bluetooth connectivity is stable. Look for signs of excessive surface scratches on the multi-touch top — may impair gestures. Ensure the firmware / Mac recognizes it fully (gestures working). Upgradability / Limitations Not user-upgradable: You cannot replace the internal battery or change internals easily. Design limitation: The USB-C port remains on the bottom of the mouse, meaning you cannot use it while charging unless you flip it. This design is still criticized. Ergonomics: The flat, low-profile design is stylish but may not suit extended-use comfort for some users.
