Solar Pond Air Pump Rotary Oxygen Aerator for Aquarium & Outdoor Fishing — Water Circulation Ventilator

Solar-powered aeration unit designed for ponds and aquariums. Built with a pure copper core and a lithium battery, the unit delivers a cycle life of up to 500 times and, when fully charged, can operate continuously for about 15-20 hours. Its compact footprint and low-noise operation provide a high gas output and extended service life. The internal circuitry is managed by an imported single chip microcomputer, offering intelligent control with constant voltage and constant current charging plus overcharge and overdischarge protection for improved safety. Suitable for oxygenating ornamental fish tanks, home and company aquariums, and small-scale family fish farming; particularly useful for emergency oxygenation during power failures, for wild fishing trips, and for transporting a small amount of aquatic products.
