The P10i is an i-Generation 21700 Tactical Flashlight designed with the i-generation ultimate revolution. Utilizing a Luminus SST-40-W LED and an optical system combined with crystal coating and “Precision Digital Optics Technology" (PDOT), it has a max output of 1,800 lumens, a max throw of 290 meters and a peak beam intensity of 21,100cd, ideal for law enforcement, assault operations, self defense, search and patrols.

The P10i is powered by a 21700 i Series Battery and compatible with 2 x CR123/RCR123 batteries. As a patent product developed by NITECORE, the 21700 i Series Battery is a proprietary 21700 rechargeable Li-ion battery featuring dual way output with positive and negative polarities at both ends and a high energy density. Thanks to the groundbreaking technology and techniques, it enables a highly efficient output by minimizing the loss of power due to internal resistance and is compatible with modular extensions of intelligent communications and controlling systems. It offers 50 hours extended runtime on LOW Level (35 Lumens).
