Specification:
Output Voltage: 3.3V/5V
Size of the Breakout Board: 75 x 35 mm（2.95*1.37in）
Maximum Output Current: 2.4A (we suggest to use it under 2A)
Two Modes of Supplying Power: Insert the rechargeable battery or use usb type-c

Intelligent Identification Load:
After inserting the battery into the module, insert the module into the breadboard and press the switch knob. If the experiment is done on the breadboard, the module will start to supply power.
When the experiment is stopped on the breadboard, long press the switch for 10 seconds to stop the power supply and enter the standby state. Standby power consumption less than 100μA.
When no device is connected, the led light automatically turns off in 40 seconds

Note
1.There are marks of negative/positive anodes in the module, and they can not be inserted inversely into the breadboard or the chips of the module will be burn.
2.This module has protection of overcurrent, overvoltage, and short-circuit for output or input; and module over temperature protection, instantaneous withstand voltage 12V.
3. It is not recommended that input and output work at the same time, because the voltage is less than 5V
4. Note: This product does not have a charging protocol and cannot power devices with a communication protocol
5. It is not recommended to charge the battery below 3000 mah, unless it is with a protection board, otherwise the current is too large to damage the battery.
6.Pay attention to the correct installation of the battery. The reverse installation may cause damage
