During the voltage conversion process, there is some power loss. This loss is typically around 10-15%. For our calculations, let’s assume a power loss of 12%.
Now, let’s calculate the approximate number of charges:
Step 1: Calculate the effective capacity of the power bank
Effective Capacity = Power Bank Capacity * Charging Efficiency
Effective Capacity = 26800 mAh * 0.75
Effective Capacity = 20100 mAh
Step 2: Calculate the usable capacity after power loss
Usable Capacity = Effective Capacity – (Effective Capacity * Power Loss)
Usable Capacity = 20100 mAh – (20100 mAh * 0.12)
Usable Capacity = 17688 mAh
Step 3: Calculate the number of charges
Number of Charges = Usable Capacity / Battery Capacity of Device
Number of Charges = 17688 mAh / 3000 mAh
Number of Charges ≈ 5.9 (round down to 5 charges)
Keep in mind that these calculations provide an approximate estimation. Actual results may vary depending on various factors such as the charging conditions, cable quality, and the age of the power bank.
