In the end, you can roughly estimated the “actual” battery capacity of a power bank for charging devices at about two thirds of the capacity stated at a 3.7V nominal voltage.

How many volts does a power bank battery last?

A current of 1Amp or 1000mA will circulate through it as 5V is the standard USB output. The voltage is monitored with a voltmeter for a determined number of hours according to the power bank capacity. If the power bank battery lasts for the same number of hours as listed in the capacity, then it is the actual capacity.

What is the capacity of a power bank with a 5V output?

Power banks use a USB-C port to charge other devices, these ports have a voltage of 5V and not 3.7V. So, when the 3.7V is converted to 5V the capacity of the power bank drops.
