Summer road trips are back, and Prime Day’s June 23‑26 sale drops prices on three Bluetooth tracker cards many travelers deem essential. The Chipolo CARD (2025) leads with magnetic wireless charging, a year‑long battery per charge, and IP67 waterproofing, while tying into both Apple’s and Google’s Find My networks. Rechargeability is scarce in this segment, making the Chipolo’s endurance a standout.

Life360’s Tile Slim offers a rugged IP68 rating and a three‑year sealed battery that cannot be swapped or recharged. Integrated into the Life360 app, the slim card works on iOS and Android, delivering reliable out‑of‑range alerts via the company’s extensive device network. Because the cell cannot be replaced, users must plan a full replacement after three years, a trade‑off many accept for the upfront cost.

The UAG Metropolis Tracker Card rounds out the trio, sporting a hexagonal design, Qi or MagSafe charging, and IPX4 splash resistance. Though its battery lasts roughly five months—shorter than the Chipolo—iOS users gain extra features like out‑of‑range notifications. With all three cards supporting both Find My ecosystems, shoppers can secure luggage, keys, or passports without adding bulk.
