Water and dust protection varies by model. Some keychain-style trackers are listed with an IP66 rating, while some disc-style trackers list IP67. Check each product’s specifications for the exact IP rating before purchase.

Some trackers advertise ultra-wideband (UWB) for high-precision, step-by-step locating. Others rely on a large, crowd-sourced device network that leverages signals such as GPS, Wi‑Fi, and cellular to help pinpoint items when they’re out of Bluetooth range. Check the product details to see which method each tracker uses.

Sizes vary by form factor. Compact disc-style trackers are about 1.26 inches (around 32 mm) across, while rectangular or tag-style trackers can be a few inches long. Listed weights range roughly from 0.03 pounds for very small keychain options up to about 1.48 pounds for larger tag-style items. Refer to the product page for precise measurements.

The results include several common types: luggage-style tracker tags, compact keychain trackers, and small disc-style tags intended for keys, bags, or luggage.

Trackers use three main battery approaches: built-in rechargeable batteries (some listings note single-charge runtimes around 8–12 months), user-replaceable CR2032 coin cells, and sealed/non-replaceable multi-year batteries (some listings cite up to about 3 years). Always check the specific product listing for exact battery type and expected lifetime.

Listed connection ranges vary by model and environment: about 10–20 meters (indoors) and 20–50 meters (outdoors) for some trackers, and up to about 250 ft (≈76 m) for another. Real-world range depends on obstacles, interference, and both devices’ antennas.

Trackers use built-in metal key rings or compact keychain designs and luggage tags with adjustable straps. Some small tags are compact enough to slip into bags or wallets; reviews note that certain items may require separate holders or cases for secure attachment.
