Olight imini 2 Rechargeable Key Ring Flashlight (OD Green)

Barely bigger than an AirPod, the Olight imini 2 Rechargeable is one of the smallest key ring flashlights you're likely to come across, and maybe the handiest. The light is operated by pulling the front half off its base—no fumbling with a switch or twisting head. The back of the light unit is magnetic, so you can stick it on any metal surface for 50 lumens of light. Pop it back on the key ring base when you're done. Recharging is clever and easy, just insert the integrated USB-A plug into your computer, a wall wart, or any USB-A port. The imini 2 will run for an hour on a fresh charge.
