How Much Power Do You Need in a Portable Battery? mAh,
Battery Capacity (mAh or Ah): Battery capacity refers to the total amount of energy a battery can store, measured in milliamp-hours (mAh) or amp-hours (Ah). A higher value indicates a greater ability to hold energy. For example, a battery with a capacity of 10,000 mAh can typically power a device that draws 1,000 mA for approximately 10 hours.
Charging Capacitors: How Many Can You Power With A 600mAh Battery
A capacitor stores energy, while a battery provides power over time. The mAh rating of a battery indicates how much current it can deliver for a specific duration. For example, a 600 mAh battery can provide 600 milliamps for one hour or 300 milliamps for two hours. When considering capacitors, their capacity is measured in farads.

The actual power in watts the pack holds can be calculated by multiplying the Ah (1000mAh == 1Ah) with battery voltage (That is very theoretical though as the voltage will decrease as the battery discharges, and there are other factors such as power loss in various places). So, with equal mAh rating the 14.8v pack would have more power.
