How Many Charges Out Of 10000mah. P V I. This is never 100 acc.

A very common mistake among those of us who want to know the number of charges we can get on our devices with a power bank is to divide the capacities of both devices ie. It also doesnt use voltage in its calculations so its more precise. This is never 100 acc.
This can be as a result of a number of the capability of the power bank is lost in conversion.
This is with average not upgraded but shimmed lubed AEGs. This is with average not upgraded but shimmed lubed AEGs. Again as an example a 1900mAH battery can supply 1900mA of current to a circuit for one hour and then it will have used all of its charge. 2200 mAh 22 Ah so if you multiple the C rating by the amp-hour rating of the pack you get the amp rating for charging or discharging.
