Description of buttons, LEDs and functions:

– Button: When power is on, press and hold the selection button for 2 seconds to convert 500mA 1000mA charging current. When charging the battery, press the SELECT button to change the type of rechargeable battery. When the battery type is selected ( Example 3.20V 3.85V) 5 seconds into the charging state.

– LED: The charger is connected to the 5V power supply. All the LEDs of the charger are fully illuminated instantly. If the battery is not placed in the charging slot, the 500mA (LED) indicator is always on and the other lights are off,

When there is a battery, 4 LED lights are all on, 3.7 LED will flash. At this time, you can press the button to select the type of battery you need to charge. If you don\’t select it, enter the default battery after 5 seconds to charge. The indicator flashes at the corresponding battery level. Press the button to check the charging type (no power indication) and return to the charging state after 5 seconds. When not powered, load the battery to check the power ratio (off after 5 seconds, you need to check and press again)

– USB output indication: When the USB output is detected, the battery indicator lights up for 10 seconds and then turns off. Press the button to check the battery level.
