Calculating the Number of Charges
To determine the number of charges you can expect from a 5000 mAh power bank, you need to take into account the capacity of the power bank and the capacity of the device’s battery that you plan to charge. Here’s a general formula to calculate the number of charges:
Number of Charges = (Power Bank Capacity in mAh * Efficiency Percentage) / Device Battery Capacity
Let’s break down the formula:
- Power Bank Capacity: This refers to the mAh rating of your power bank, which in this case is 5000 mAh.
- Efficiency Percentage: As mentioned earlier, not all power banks have the same level of efficiency. Efficiency is often expressed as a percentage and represents the energy conversion rate. For example, if your power bank has an efficiency rating of 80%, you would use 0.80 as the efficiency percentage in the formula.
- Device Battery Capacity: This refers to the mAh rating of the battery in the device you want to charge. You can usually find this information in the device’s specifications or settings.
By plugging in the respective values into the formula, you can determine the estimated number of charges your 5000 mAh power bank can provide for your specific device.

Let’s assume you have a 5000 mAh power bank with an efficiency rating of 85%. You want to calculate the number of charges it can provide for your smartphone, which has a battery capacity of 3000 mAh.
Using the formula mentioned earlier:
Number of Charges = (Power Bank Capacity in mAh * Efficiency Percentage) / Device Battery Capacity
Plugging in the values:
Number of Charges = (5000 mAh * 0.85) / 3000 mAh
Simplifying the equation:
Number of Charges = (4250 mAh) / 3000 mAh
Number of Charges ≈ 1.42
Based on this calculation, you can expect to get approximately 1.42 charges from your 5000 mAh power bank for your smartphone with a 3000 mAh battery.
Keep in mind that this calculation is an estimate and may vary depending on the efficiency of your power bank and other factors affecting battery performance.
