Different abilities require different times, and the power of the flashlight has a lot to do with it too!
Commonly used LED flashlights have a power of about 5W, and the average voltage of lithium batteries is 3.7V. Taking a 2200mAh battery as an example, the time theoretical discharge is 2.2 × 3.7÷5 = 1.6 hours.
Q5 The lamp bead is 5 watts. How long it will continue to discharge depends on two factors: one is the designed discharge current of the flashlight driver board, and the second is the battery capacity of the 18650. Whether the discharge current is 800mA per hour and the battery capacity is 1600mA, it can be used for more than 2 hours with continuous discharge. The discharge current of a flashlight is generally the maximum current in strong light mode. If low light mode is used, the discharge time continueswill more than double. For example, strong light discharge for 2 hours, weak light can be used for more than 4 hours.
