A. Meet different needs: You can enjoy a comfortable bath in cold weather or use the heater to boil water and soak feet overnight to keep them warm. Applicable containers include bathtubs, plastic bathtubs, inflatable swimming pools, and footbaths. B. Heating time: Immerse the electric water heater in the holder, and it can heat up in a few minutes. The 3000W electric heating makes water heating more efficient, bringing 5 gallons of water to a boil in a few minutes. Simply place the heater in water and connect it to an easy-to-use power source. C. Heating element performance: Strictly tested heating elements with a service life of over 10,000 hours are selected, featuring sturdy construction and technology to help ensure durability and reusability. D. Safety features: The electric immersion heater uses copper wire, which facilitates heating and conducts power. The ABS shell includes stainless steel, which is rust-resistant and can help prevent the heater from touching the human body, contributing to safer use and fewer accidents. E. Timer function: The immersion heater has a timer function. Press the SET button to set the time. When the time is up, the power supply automatically turns off and an audible alarm sounds, helping to prevent accidents caused by forgetfulness at work. There's no need to wait by the side during use, which is safer and more convenient. F. Easy operation: Place the heater on a level surface (the heater has a safety level line). Plug the plug into a grounded socket. Check the operation indicator on the socket to ensure the heater is turned on. Then the portable heater starts working. Warning: The power cord and handle must not be immersed in water.
