First, warning

1. This charger can only be filled with cylindrical lithium ion battery (3.7V, 3.8V), nickel-hydrogen/nickel-cadmium, lithium iron phosphate battery,

2. Before use, please refer to the manual carefully, pay attention to the recommended charging current of the rechargeable battery, do not exceed the recommended current charging,

3. Charge with 5V USB adapter (adapter current recommendation 2A),

4. The charger may be hot when charging and discharging, be careful not to burn it,

5. When you stop using it, please unplug the power supply and remove the battery,

6. Can only be used in normal indoors.

Second, the charger requirements and functions:

1. Button: When power is on, press and hold the selection button for 2 seconds to change 500mA 700mA 1000mA 2000mA charging current,

When powering up the battery, press the SELECT button to change the type of the rechargeable battery. When the battery type is required to be charged (Example 3.20V 3.85V), the battery is charged for 5 seconds.

2. LED: The charger is connected to the 5V power supply. All the LEDs of the charger are fully illuminated. 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.
