NITECORE P20iX Xtreme Features and Specifications

NITECORE P20iX Xtreme flashlight features physical dimensions of (L x W) 5.57 x 1.25 inches (141.5 x 31.8 mm), and it weighs 4.09 ounces (116g) - the flashlight is too large to be considered as pocket-size, but it is not much larger and can be easily carried at the belt, in the backpack and similar.

The flashlight supports the use of a high-power 21700 battery or the use of a pair of CR123A/RCR123A batteries using a special battery holder.

The use of the Nitecore NL2150HPi 21700 battery is highly recommended since it offers better performance than a pair of CR123A/RCR123A batteries. Personally, if You want an EDC flashlight that will be used rarely, a pair of CR123A batteries is a good choice, just be aware of reduced output and don't try to charge them via USB-C cable.

  • Tactical Mode: 4 brightness levels (Turbo, High, Mid, Low) and Strobe Mode.

When the flashlight is powered by Nitecore i-Generation 21700 battery, the output modes feature:

  • Turbo Mode: 4000 lumens, 30 minutes, 220m, 12200 candelas,
  • Higher Mode: 1700 lumens, 2h, 145m, 5250 candelas,
  • High Mode: 850 lumens, 2h 30 min, 103m, 2670 candelas,

  • Strobe Mode: 4000 lumens.

Note: Turbo Mode runtime of 30 minutes is tested without temperature regulation. In real life, that means that the actual Turbo Mode will last less due to the overheating. Personally, use Turbo Mode only for very brief periods of time in order to prolong the runtime on a single battery charge.

When the flashlight is powered by a pair of CR123A (1700 mAh) batteries, the output modes feature:

  • High Mode: 1060 lumens, 1h, 116m, 3360 candelas,

  • Ultra-Low Mode: 2 lumens, 120h, 5m, 5 candelas,
  • Strobe Mode: 1060 lumens.

 Obviously, when the flashlight is used often and when performances are important, use Nitecore 21700 battery.
