Apple Air Tag 4 Pack MX542

The Apple AirTag (4‑Pack) – Model MX542 is a set of four smart trackers designed to help you locate and keep track of your most important items using the Find My app on Apple devices. Whether it’s keys, backpacks, luggage, or pets, AirTags make it easier to find misplaced items with precision and ease.

Each AirTag uses Bluetooth and Ultra Wideband (UWB) technology to communicate with nearby Apple devices. When paired with an iPhone equipped with a U1 chip (iPhone 11 or later), you can use Precision Finding to see the exact distance and direction to your AirTag — guiding you with on‑screen directions. AirTags also leverage the Find My network, which uses millions of Apple devices to help locate items even when they’re out of Bluetooth range.

AirTags feature an IP67 water and dust resistance rating, so they can withstand splashes and dust when attached to everyday items. The included replaceable CR2032 battery keeps each AirTag powered for about one year under normal usage, and changing it is simple — no charging cables required.

Setup is fast — just bring an AirTag close to your iPhone or iPad and follow the on‑screen prompts. In the Find My app, you can assign custom names and emoji to each tracker and view their last known location on a map.

The 4‑pack offers excellent value if you want to protect multiple items at once, perfect for families or frequent travelers.
