Loadout Room: ASP Sentinel e3 and Sentinel Xe3 Triple Fuel Tactical Flashlights
"Because there is no such thing as having too many backup options on the street, ASP has introduced its first triple-fuel flashlights; the Sentinel e3 and Sentinel X e3. These lights ship with a 16340 lithium-ion battery that recharges inside the light, providing a potent 400 lumens of output. If you don’t have the time or place to recharge, just swap out the rechargeable battery for a CR123A disposable cell. No CR123? No problem—you can also put in a common AA battery in a pinch, with no special adapter needed."
