How Do You Determine the Capacity Needed in a Portable Power Bank?

To determine the capacity needed in a portable power bank, consider the following factors:


FactorDescription
Device Battery CapacityCheck the mAh (milliamp-hour) rating of the devices you intend to charge. This is usually found in the device specifications.
Number of ChargesDecide how many times you want to charge your device on a single power bank charge. For example, if your smartphone has a 3000mAh battery and you want to charge it twice, you would need at least a 6000mAh power bank.
