The Apple AirTag is a compact tracking device designed to help you keep tabs on your personal belongings. Each unit features a polished white and silver finish, measuring 31.9 mm in diameter and 8.0 mm in height, which makes it easy to attach to keys or slip into a bag without adding bulk, weighing only 11 g. Inside, the Apple-designed U1 chip enables Ultra Wideband technology for Precision Finding, allowing you to locate your items with high accuracy when using an iPhone 11 or later. For broader searches, it utilizes Bluetooth connectivity and a built-in speaker to alert you to its location. Built to withstand daily wear, the device carries an IP67 rating, meaning it can handle dust and remain submerged in up to one meter of water for 30 minutes. It operates reliably in temperatures ranging from -20° to 60° C, ensuring it works whether your luggage is in a cold cargo hold or a warm car. The system is powered by a user-replaceable CR2032 coin cell battery, so you can easily maintain the device yourself over time. This pack includes four units, each arriving with batteries installed and ready for use with iPhone, iPod touch, or iPad models running iOS or iPadOS 14.5 or later. An integrated accelerometer and NFC capability allow for a simple tap to activate Lost Mode, making it a practical tool for anyone who frequently misplaces their essentials.
