Troubleshooting:
Fault phenomenon
Fault check and cause
The solution
Unable to charge
Measuring the voltage of 4 groups of batteries. when one of the battery voltages exceeds 4.25V, the protection board will activate overcharge protection.
Pair the battery pack well, do not mix the good battery and the bad battery.
Unable to discharge
Measuring the voltage of 4 groups of batteries. when one of the battery voltages is lower than 2.7V, the protection board will activate the over-discharge protection.
Pair the battery pack well, do not mix the good battery and the bad battery.
Charging/discharging failure
0V, 4.2V, 8.4V, 12.6V, 16.8V miswired
Rewire or replace the new board (human failure, no warranty)
Overcharge/over-discharge failure
0V, 4.2V, 8.4V, 12.6V, 16.8V miswired
Rewire or replace the new board (human failure, no warranty)
Discharge protection
Check that the battery pack has sufficient discharge capability and check that the load"s starting current exceeds the over-current protection current of the protection board.
Replace the battery pack with a higher discharge capacity, or a protective plate with a larger current (super working range)
Component soldering
There is no connection between one of the components and the PCB pad.
Repair welding
Component welding
There is a short circuit between two or more pins of the component.
Remove the component and re-weld
Electrostatic breakdown A
In the unpowered state, measure the G, D, and S poles of the MOSFET. If the forward and reverse resistances of any two pins are 0u03a9, it indicates that it has broken down.
Remove the replacement MOS tube
Electrostatic breakdown B
Remove the MOS tube and measure the resistance of the G and D, G and S poles of the MOS tube. If there is a resistance indicating that it has broken down, the resistance should be infinite.

Looking at the Designed for Usability photo I would have said that it was a USB C connector. Either way it comes with a cable according to the description.
