What is the capacity of a power bank?
The capacity of a power bank is measured in milliampere-hours (mAh) and represents the amount of charge it can hold. The higher the mAh rating, the more charge the power bank can store, and thus, the more times it can recharge your devices.
How many mAh are in a 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.
What does Watts mean on a powerbank?
The number of watts stands for a total energy that powerbank can output at a given time. For example 18W powerbank can provide 18W for 1 hour, or 1W for 18 hours. Some larger devices, like laptops may require a higher power supply, meaning you should use a powerbank with more watts. In other words, more watts also means a faster charge.
How to choose a power bank?
So you want a power bank with fast, efficient charging technology. Capacity is measured in milliampere hours (mAh). The higher the number the greater the capacity and the more devices you can charge before the power bank's Lithium-ion battery needs its own charge. Speed is measured in watts (w).
How many times can a power bank charge a phone?
So, if you have a phone with a 3,000 mAh battery, having a power bank that has a 6,000 mAh will allow you to fully charge it to 100% just around 2 times.
