The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection. The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection. When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel. Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage. This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery. Compatible only with MacBook Air featuring MagSafe 2 power port. Knowing which specific Mac model you have is important. If you are running OS X Lion (10.7) or later go to the “” menu at the top left of your screen, choose “About this Mac” then click the “More Info…” button.

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.
