The P20i flashlight is from Nitecore's new i-Generation series offering the ideal tactical light; it comes with a 21700 battery, has Strobe Ready technology, high performance and is rechargeable via USB-C. 

The Nitecore P20i offers a maximum output of 1800 lumens from the Luminus SST-40-W LED when using the included 21700 4000mAh i-series battery. The torch is also compatible with 2 x CR123 single use or RCR123 li-ion cells which will provide a lower output and cannot be recharged inside the light.

Additional NL2140i can be purchased here.

The flashlight is operated using a dual tail switch interface, made up of the power button to turn the light on and off, and a mode button to cycle through the brightness levels. The Strobe Ready technology also means the Strobe mode can be accessed at any time by pressing and holding the mode switch. The Strobe features randomly changing frequencies which can cause strong dizzying effects, to be used cautiously in emergency situations.

The P20i is rechargeable via USB-C and comes with a charging cable which can be plugged into the port at the head of the light. A charging port cover sits over the USB-C port to protect against dust, water and impacts.

Additionally, the Nitecore P20i features Advanced Temperature Regulation (ATR) to maintain optimal performance, a power indicator to show the battery voltage and a strong strike bezel which can break glass in emergencies.
