Like Eufy and Pebblebee’s wallet trackers, Ugreen’s Finder Slim features a rechargeable battery instead of a disposable one. Battery life is claimed to be up to 12 months between charges, which is much shorter than the three years Tile says its wallet tracker will work, but you can potentially keep using Ugreen’s for even longer than that.
The downside to ultra-thin rechargeable wallet trackers like the Finder Slim is that they’re too thin to use a standard USB-C charging port. It instead relies on a proprietary charging cable with a magnetic connector you’ll need to make sure you don’t misplace before needing it again in another 12 months. On top of that, if product imagery is accurate, the proprietary charging cable Ugreen includes is only USB-A compatible.
The Finder Slim works with Apple’s Find My network but skips support for Google’s Find My Device network entirely. Remote tracking allows you to see the Finder Slim’s last reported location on the network, and it will also trigger left behind reminders when it’s initially separated from your iPhone. A built-in 80dB alarm should make it easy to pinpoint the exact location of the tracker when it’s nearby and within earshot — even when it’s stuffed inside a wallet — and it’s IP68 rated, so it can survive a complete dunking for up to 30 minutes. Just don’t expect to be able to track it down if it ends up in the drink.
