A small rechargeable flashlight is the one you actually carry, because it is in your pocket when the big one is in a drawer. Under 4.5 inches, USB-C, a real clip, and enough output to matter. This guide ranks the ones we sell by size, from a keychain light to the Baton.
1. Fenix PD25R, 92 mm, 78 g
800 lumens to 250 meters from a 16340, with a tail switch and a side switch, five levels, a two-way clip, and IP68. The smallest light with a real tactical interface. $59.95.
2. Olight Baton 4 Pro, 111 mm, 114 g

5. Powertac SOL keychain light
