So you’re in the market for a power bank for your smartphone, but with so many options out there, how do you know which one is right for you? Whether you’re always on the go, or just tend to have a knack for draining your battery, finding the perfect power bank can make all the difference. In this article, we’ll break down the key factors to consider when choosing a power bank, so you can ensure that you never run out of juice when you need it most.
1. Capacity
1.1 How much capacity do you need?
When choosing a power bank for your smartphone, it’s essential to consider the capacity you require. The capacity of a power bank is measured in milliampere-hours (mAh) and indicates how much charge it can hold. To determine the capacity you need, you have to consider your smartphone’s battery size.
The battery size of smartphones typically ranges from around 2000mAh to 5000mAh. Suppose your smartphone has a battery size of 3000mAh. In that case, it is recommended to choose a power bank with a capacity slightly higher than that to ensure you can fully charge your phone at least once on a single charge.
1.2 Calculating the capacity required
To calculate the capacity required, you can consider the following formula:
[ Capacity required = Battery size of your smartphone x Number of times you want to charge your phone ]
For example, if your smartphone has a battery size of 3000mAh and you want to charge it twice on a single charge, the capacity required would be 3000mAh x 2 = 6000mAh. In this case, you should consider a power bank with a capacity of 6000mAh or higher.
1.3 Understanding mAh rating
It’s important to understand the mAh rating of a power bank and its relationship with the actual capacity it provides. The mAh rating indicates the amount of charge a power bank can theoretically deliver, but due to inefficiencies during charging and discharging, the actual usable capacity may be lower than the stated mAh rating.
For example, a power bank with a 10000mAh rating may offer a usable capacity of around 8000mAh. So, when comparing power banks, it’s essential to consider the actual usable capacity rather than just the mAh rating.
