Intelligent Memory Circuit
The flashlight memorizes the last brightness level used in the General mode, the next time it is turned on, it will recall that previously used General brightness level.
Over-heat Protection
The flashlight will accumulate a lot of heat when it is working at Turbo brightness level. When it works at Turbo for 5 minutes, the flashlight will automatically downshift to High output to prevent the light from overheating. If the Turbo output is needed, please reset it again. The flashlight could be damaged or the normal service life could be shortened because of continuous use like this.
Low-voltage Warning Function
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level. When this happens in Low output mode, the flashlight blinks three times every five minutes to remind you to charge the light or replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work until the over-discharge function stops the battery from working.
Note: This only works on 16340 rechargeable Li-ion battery. When the voltage of 16340 battery is detected lower than 3V, low-voltage warning function will fail if the flashlight is turned on again.

Then draw the magnetic end of the charging cable close to the flashlight, the charging cable will attach to the charging port automatically and the charging has begun. The indicator light will flash green in charging process. The indicator light turns solid green when charging completely done. The normal charging time is about 1.5 hours.
