Key Definition: A portable charger (also called a power bank) is a battery pack with USB ports that charges devices without a wall outlet. Capacity is measured in mAh (milliampere-hours) — higher numbers mean more charges. As of 2026, GaN (Gallium Nitride) technology has become the industry standard, enabling higher wattage in smaller form factors compared to traditional silicon-based chargers.
