What is a power bank?

A power bank is a portable charging device with a built-in lithium-ion or lithium-polymer battery, designed to recharge smartphones, tablets, Bluetooth earbuds, and other gadgets. It works by converting electrical energy into chemical energy for storage during charging, then reversing the process to output power via USB ports. Capacity is measured in milliampere-hours (mAh); for example, a 10,000mAh power bank can typically charge a standard smartphone 2-3 times, depending on the device’s battery size and efficiency.
