Battery-powered fans use an internal cell, usually charged over USB or Type-C, so they run cordless for a fixed number of hours before needing a recharge, unlike a mains-powered table fan such as the Usha Maxx Air Ultra, which runs continuously but must stay plugged in. Battery capacity (in mAh) is a rough guide to runtime, and higher RPM ratings generally mean stronger airflow.
