The water heater is constructed from stainless steel, ensuring high safety and a long service life. The power cord features pure copper wiring with a PVC sheath, providing resistance to high temperatures and oxidation, eliminating concerns about leakage, and offering durable, safe performance. Equipped with a 2500W high-performance heating element made of 25 cm stainless steel, the unit delivers rapid, uniform heating throughout the entire tube, quickly raising the water temperature and reducing wait time. Simple and convenient to use. The U-shaped heating element includes a stainless steel protective cover, preventing direct exposure. This allows safe use with inflatable products or plastic containers, helping to prevent burns. Features intelligent temperature control: when the water reaches 75°C, the unit automatically shuts off for safety. The rear indicator light turns red during operation and turns off automatically once heating is complete. Versatile for various applications: compatible with inflatable swimming pools, plastic buckets, plastic pools, wooden barrels, ceramic baths, and other containers, making it a helpful household utility.
