Overview of the board for a homemade power bank

Hello. Today there will be a review on the module-board for assembling a homemade power bank. It has two USB outputs. One output produces a current of 1 ampere, and the second 2.1 amperes. The module is very cheap, but has a number of protections and a flashlight.
Shop on Aliexpress where you can buy the module:

I have this module it stops charging mobile if we connect 2 or 3 batteries to module after 5 mins. Can you figure out what is the minimum no. of batteries required to charge one 5000 mah mobile single time. can we give more than 5 volts to this module.

Unfortunately, I can't change anything. I installed it in the case and sealed it. And why apply more than five volts to it?

@@Den_Electro_channel I was thinking of connecting laptop battery to the module but the output of the battery is 10 volts hence asked.

Now I understand the question. This module only increases the voltage. 10 volts cannot be connected. Only voltage is 3-4 volts. And he will increase it to 5 and that’s it
