Understanding the true capacity of a power bank and what output it can deliver becomes very important. The last thing you want is any kind of misunderstanding, as you might have less power than expected and that on its own can be a major issue. That’s why we want to know the amount off charges we can get with a power bank.
How do you define the real power bank output capacity?
The formula is simple, the number of charges can be found via dividing the actual power bank capacity to the smartphone capacity. For example, a 10000 mAh power bank refers to the internal battery capacity. You want to know how much stored energy is there, which is the battery capacity multiplied with the nominal voltage of the battery.
Understanding the energy efficiency is also just as important too. This is 100 x output energy / stored energy. No matter how much we try, the energy efficiency will never be at 100%.
Understanding the output capacity
The formula for identifying output capacity brings is to do this: “Efficiency x (battery voltage x battery capacity)/ charging voltage. This formula is suitable for pretty much any charging voltage. Through this we get to understand that a 10000 mAh power bank actually comes with 6545 mAh for the output for if the voltage is 5V. So yes, the voltage does matter quite a bit.
As you can see, 10000 mAh will not give you this specific amount of power. It gives more than half, around 65%, but the 10k mAh refer to the internal battery capacity here and not what you will get from the unit. That’s a misconception and unfortunately a lot of people get confused by this type of thing.
In the end, you want to calculate the real output capacity of a power bank to ensure that it will deliver the results you want.
