Used Apple Magic Trackpad 2

Magic Trackpad is wireless and rechargeable, and it includes the full range of Multi-Touch gestures and Force Touch technology. Sensors underneath the trackpad surface detect subtle differences in the amount of pressure you apply, bringing more functionality to your fingertips and enabling a deeper connection to your content. It features a large edge-to-edge glass surface area, making scrolling and swiping through your favourite content more productive and comfortable than ever.

Magic Trackpad pairs automatically with your Mac, so you can get to work straightaway. The rechargeable battery will power it for about a month or more between charges, and it also includes a woven USB-C to Lightning Cable that lets you pair and charge by connecting to a USB-C port on your Mac.
