Features: Detachable design: The cup can be removed for easy cleaning and carrying. Oxygen-rich design: Hydrogen is produced by micro-electrolysis. The higher the mineral content in water, the more efficient the electrolytic effect and the higher the hydrogen content. Stable and portable: Electrolysis technology promotes the stable combination of hydrogen and water, providing high hydrogen concentration and good stability. Portable hydrogen water generator helps deliver healthier water. Ideal for making hydrogen-rich water anytime, anywhere. Safety: Hydrogen-oxygen separation technology allows electrolysis of pure water, adding hydrogen while reducing harmful substances such as ozone and chlorine. Convenient for travel: Our portable bottle lets you enjoy hydrogen-enriched water wherever you go, supporting your health on the move. Note: 1.
