How many volts are the input and output voltages of the charging devices for a regular LED flashlight?
At present, there are many new products available in the market, and their output and input voltages are different. We should pay attention to the instructions for use.
The input voltage of the charging device for an ordinary LED flashlight is 220 volts alternating current, and the output is 4. 2 volts direct current. LED flashlight charging device, is a capacitor step-down to 6 volts, rectifier diode, into 4. 2 volts direct current into the nickel zinc battery for the bulb to light.
LED flashlight charging device input voltage 220V, output voltage of about 0.3V 3.6V
