(Labeled capacity of the power bank x 3.7 / output voltage of power bank) x 0.85 / battery capacity of device = Total number of recharges. Now, that you have the formula all let's try an example. We can use a 40,200 mAh power supply and an iPhone 8 which has a battery capacity of 1821 mAh. Second we multiply that by 3.7.
The battery of a power bank consists of lithium-ion (Li-Ion) or lithium polymer (LiPo) cells. Usually, they use cells with a nominal voltage of 3.7 volts (V) and a capacity ranging from 1500 to 5000 milliampere-hours (mAh). Can I Charging 3.6 v battery with 5V?
That's why you'll see watts or W in most power bank specifications because this now refers to how much energy it can deliver to your phone to get it charged. Using the formula, if you have a 10,000 mAh power bank with a 4.8 A output at 5V, your power bank has a power of 24W. This means that it can deliver 24W of power to a phone, for example.
If you are using a power bank in a high-temperature environment then the efficiency rate will drop. That means the power bank will lose more power trying to convert the voltage. It's best to use a power bank in a cool temperature area. Therefore, the real battery capacity depends on the quality of your power bank.
You'll have 5,000 mAh power banks, 10,000 mAh, or even 20,000 mAh. mAh is short for milliamp-hours, which is a unit of charge that refers to the amount of “charge” that a battery or power bank can hold. Let's say that your phone's battery, which is also measured in mAh, is a cup of water.
