We’ve already talked about some (excellent) rechargeable products that have Tile built right in, but if you don’t want or need them or just want something for your current keychain, nonda’s got you covered.

The nonda AIKO, from the same company that brought you one of our favorite car chargers, is basically a Tile without the Tile network, and with a micro-USB port. The battery lasts four weeks and AIKOs start around $12 right now based on current Amazon pricing if you spring for a 4-pack.
