This mobile power supply has a built-in lithium battery protection IC, providing overcurrent, overvoltage, and undervoltage protection. It supports 3V/1A and 5V/3A voltage outputs. The installation of the battery requires determining the positive and negative terminals, clearly marked on the board to avoid errors that may damage the module. The battery voltage operates normally between 3.2V to 4.2V. The 5V voltage output has a rated current of 3A, with a maximum support of 3.6A depending on the quality of the 18650 battery.
