The Century 16" DC & AC Energy-Saving Wall Fan (FRCB-40-DC) is a versatile, non-rechargeable hybrid fan built specifically for low-power and off-grid setups. Because it doesn't have a built-in battery, it relies on a unique 2-in-1 power system: it can run normally on standard AC electricity, or it can be powered directly via its DC input (9–28V) using an external solar panel, a large inverter battery, or a power bank. Operating at an ultra-low 15 Watts, it uses a five-blade design and a durable, extra-low-noise motor to deliver strong airflow without draining your external power sources. It comes equipped with both an AC adaptor and a DC cable, featuring three speed settings, automatic oscillation, and adjustable tilt.
