• Extends battery cycle life by charging battery that reads 4.05V or lower
• Precise voltage detection design +/- 1%
• No trickle charge
• Smart charging level report system

Charging level report (charging)

• Flashlight will flash one time to report the estimated remaining charging time by reading the battery voltage (at five seconds after plugged-in)
• Flash once: > 2 hours
• Flash twice: 1-2 hours

• Optional disorienting strobe output

Operations

• Turn on the flashlight by pressing the tailcap button until it clicks.
• Twist the head to select between three output levels.
• You can pre-selected any output level before turning on the light.

• Tail strobe feature (off by default): Switch to 1st level and turn the flashlight on and off 20 times (one second or less between each click) to toggle this feature. With the tailcap strobe setting enabled, a double press of the switch button (within one second) will activate the strobe output.

• Remove the waterproof cover and insert the included type-c charging cable to charge the battery. User must turn on the flashlight switch at the tailcap to charge. 
• Flashlight will switch off the LED output during charge until the charging is completed. Restart the flashlight or switch to other brightness level to wake the flashlight with cable removed.)
• To check the charging progress anytime during charge, turn the head of the flashlight to wake the charging level report.
