Its knurled aluminum body makes the P1R effortless to grip, even in wet hands. The Peacekeeper is powered by a rechargeable 18650 lithium-ion battery and, if necessary, can also accept two CR123 lithium batteries. The 18650 battery can be charged using either one of its included wall or vehicle chargers. A 600-lumen single output, tactical version is also available.
