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 efficient the electrolytic effect and the higher the hydrogen content. Stable and portable: Electrolysis technology promotes the stable combination of hydrogen and water, high hydrogen concentration and good stability. Portable hydrogen water generator gives you healthier water. Perfect for making hydrogen-rich water anytime, anywhere. Safety: Hydrogen-oxygen separation technology replaces filter rods with higher hydrogen content. It can electrolyze pure water, add hydrogen, which is more beneficial to health, and remove harmful ozones and chlorine. Easy to get around: Our portable kettles allow you to enjoy the advantage of hydrogen water anytime, anywhere, and prioritize your health no matter where life goes.
