The charge stored in the power bank is the product of its mAh (or Ah) rating and terminal voltage. Since the terminal voltage in both cases is the same, i.e., 3.7 volts, the mAh directly defines how much power the power bank can supply. In the case of 1000 mAh and 2000 mAh power banks, the latter can store two times more power than the former.
For a 5,000 mAh battery, you can determine the watt hours by multiplying the battery’s voltage (V) by the capacity in milliampere-hours. Using a 3.7-volt battery as an example: Wh = 5,000 mAh x 3.7 V ÷ 1,000 = 18.5 Wh. Thus, a 5,000 mAh battery at 3.7 volts provides 18.5 watt hours of energy.
