I’ve put dozens of Bluetooth key finders, AirTag clones, and credit-card-style trackers through their paces over the years. They’re helpful for keeping track of my gear — I keep them in my backpack, on my keychain, and inside my wallet.

While early versions relied on proprietary chargers, newer models have adopted standard wireless charging, making them even more convenient.
