The Universal Circuit System 16″ Rechargeable AC/DC Fan (Model 3516) is a premium, high-performance cooling solution engineered to deliver reliable comfort during sudden power blackouts, outdoor excursions, or off-grid living [Image 1, Image 11]. Combining everyday household efficiency with robust emergency preparedness, this versatile pedestal fan functions as a standard AC-powered appliance while simultaneously charging its internal heavy-duty battery for seamless DC operation when the main power grid fails [Image 11].

Engineered with sustainability and adaptability in mind, the Model 3516 features a highly efficient dual-charging infrastructure. It plugs directly into traditional wall outlets for rapid charging via standard household AC currents. To ensure you never run out of cooling relief during prolonged brownouts, it comes packaged with an external photovoltaic solar panel [Image 11, Image 12]. This high-efficiency solar panel converts direct sunlight into clean, renewable energy, making it an indispensable asset for rural households, camping sites, or any area plagued by unreliable utility networks.

At the core of the fan is a dynamic 3-speed airflow system that lets you easily alternate between gentle, whisper-quiet circulation and intensive, high-velocity cooling [Image 2]. The fan’s interface is intuitively housed on an ergonomic, orange-accented base [Image 1]. This heavy-duty base serves as the control hub, hosting the speed selection mechanics, real-time battery life indicators, and dedicated power management ports designed to safeguard the system against overcharging or short-circuiting.

Beyond its primary function as a high-capacity cooling unit, the fan is built to operate as a comprehensive emergency workstation. Built directly into the sleek vertical support column is a high-intensity LED light strip [Image 2, Image 11]. This integrated lamp instantly converts the fan into a bright room illuminator, eliminating the need for candles or standalone flashlights during night-time blackouts. The wide-angled 16-inch blades are safely enclosed within a reinforced wire safety grille, ensuring optimal, child-safe wind distribution across medium-to-large rooms [Image 1, Image 2].
