You can determine the number of charges from an 11,000mAh portable charger by understanding its capacity, the capacity of the device being charged, and any energy loss during the charging process.
-
Capacity of the portable charger: The portable charger has a capacity of 11,000mAh. This means it can supply 11,000 milliamp hours of electric current.
-
Capacity of the device: Identify the battery capacity of the device you want to charge. For example, a smartphone battery might have a capacity of around 3,000mAh.
-
Energy loss: Charging is not 100% efficient. Typically, there may be around a 20% energy loss due to heat and energy conversion inefficiencies.
-
Calculation: To calculate the number of full charges, use the formula:
– Effective capacity = Charger capacity × (1 – efficiency loss)
– Effective capacity = 11,000mAh × 0.80 = 8,800mAh -
Total number of charges = Effective capacity / Device capacity
– For a smartphone with a 3,000mAh battery:
– Total charges = 8,800mAh / 3,000mAh ≈ 2.93
This means you can charge the smartphone approximately 2 full times before the power bank is depleted. Understanding these components allows users to estimate how many times they can recharge their devices using an 11,000mAh portable charger effectively.
