The Science Behind Lithium-Ion Batteries in Power Banks

Lithium-ion batteries are the backbone of modern portable electronics, including power banks. Comprising an anode, cathode, and an electrolyte, they work by the continuous movement of lithium ions, storing and releasing energy. Their high energy density, longevity, low self-discharge rate, and lightweight nature contribute to their widespread popularity. However, challenges like potential overheating and concerns related to lithium sourcing exist. Despite this, their efficiency and power make them indispensable in the current digital era, with expected further advancements in the future.

Explaining Power Bank Capacity: mAh vs. Wh
Power banks use two primary metrics to indicate their capacity: mAh (milliampere-hour) and Wh (watt-hour). While mAh measures the electric charge, giving an idea of how long the power bank can last, Wh indicates the total energy stored, revealing how much power it can deliver based on its voltage. A higher mAh suggests longer battery life, and a higher Wh can imply more energy storage for charging power-hungry devices. For daily use, mAh might be sufficient, but for travel and charging multiple devices, considering both mAh and Wh is crucial, especially with airline regulations often setting a 100Wh limit for carry-on power banks.
