The capacity of the phone's battery affects the amount of capacity you need to charge it.Some phone models need more than others.
The capacity of a power bank is one of the first features that will be mentioned by any person looking to purchase one.When buying a power bank, most buyers ignore the fact that their advertised capacity is misleading, so they end up with power banks that are short of their expectations.
To prevent this from happening to you, we have designed an easy guide so that you can choose a power bank based on your phone's capacity.
From a technical point of view, the main reason behind this disparity is represented by power losses; however, we cannot overlook the business-savvy nature of manufacturers, who disguise the real capacity to boost their sales.
Check our article "Why is there a difference between rated and real battery capacity?" to learn more about this.
It's not uncommon to see users buying power banks that can't even supply a full charge to their devices.
The rule of thumb is 1/3 of the power bank's advertised capacity.This time, using in a different way.
There is an explanation behind this equation.The actual capacity of a power bank is close to 1/3, which is the result after the energy lost in the voltage conversion and transfer.We know the battery size of our phone, even though the power bank's capacity is unknown to us.
We need a power bank that outputs this value so that we can make up for the 1/3 loss in the transfer and voltage conversion.The multiplicative inverse of 1/3 or 0.666 is used for this reason.
The power bank needs to be bigger than the one on our phone.
Simply add the result of the first equation to the number of times, as shown in the next equation, to figure out how much power the power bank needs.
If you still own an Apple product, make sure to find the battery capacity and use our formula to calculate it.
Many other models, including the J and M series, are not included in the list, just as the iPhone list is.There will be more new releases in the upcoming months.If your model is new, check its battery size and then do the math using the formula explained before.
It is highly unlikely that a power bank will match that exact number because the values are estimations.We advise you to choose a power bank with a bigger capacity than the one shown in the table.You can make sure you have a power bank that can charge your phone a certain number of times.
If you are looking for a power bank with enough power to charge your at least two times, you should pick one with a capacity of over 12000 mAh.We found that the PowerCore 13000mAh is able to do it.
You must be wondering how we found the right one.With the help of the Power Bank Review Finder, you can specify the capacity, as well as other important features, such as the number of ports and charging technology.
