3. Charge While Discharge Funtion
3.1 Open Charge-While-Discharge function:
Both of the following operation methods can enable the mobile power supply to enter the charging and discharging state:a. During the charging process, the power bank connects the load to the output USB port. The power bank simultaneously charges the built-in battery and load, and the current between the battery and load is automatically pulled by the load.b. When the output USB port is loaded and working normally, connect a charger to the input port, the power bank simultaneously charge the built-in battery and load. The current between the battery and load is automatically pulled by the load.c. When opening Charge-While-Discharge function, the input and output are automatically adjusted to 5V (fast charging function is turned off) 4. DC Output Specifications:
