What Is mAh and Why Does It Matter?
Before diving into the options, let’s clarify an important term: mAh, short for milliampere-hour. This unit tells you how much energy a powerbank can store. The higher the mAh, the more charging power it has. Understanding mAh is essential because it helps you estimate how many times a powerbank can recharge your devices.
For example, if your phone has a 3,000mAh battery:
A 5,000mAh powerbank might charge it once.
A 20,000mAh powerbank could charge it 4–6 times.
A 50,000mAh powerbank can keep your phone (and other devices) going for days.
Keep in mind that actual performance varies slightly due to energy loss during transfer and differences in device consumption.
