It comes with an easy to use charging cradle so even charging the flashlight is simple. The RC20 even features an LED Battery Level Indicator, which shines green when the battery has sufficient power, shines red when the battery is getting low and flashes red when the battery is critically low.Longevity and DurabilityNot only does the RC20 boast impressive output and practical features, but also an exceptional knack for endurance.
