1、Improve Water Quality: The hydrogen water generator utilizes SPE and PEM technology to rapidly generate hydrogen ions up to 2500‑5000ppb and release H2 and O2. Within just 5 or 10 minutes, it can convert regular drinking water into hydrogen rich alkaline water, providing you with safe drinking water and effectively reducing oxidation reactions. 2、Easy to Use: Portable hydrogen water ionizer machine is easy to use. Simply press the power button, and the light at the bottom of the cup will illuminate. After 5 or 10 minutes, you can enjoy a cup of healthy hydrogen water. When the ion bottle is activated, it generates a large number of fine bubbles. It is recommended not to reuse the same cup of water to avoid excessive pressure and damage to the device. 3、Stylish and Simple: The hydrogen water machine features a non slip EVE cushion design at the bottom for stability. The base of the hydrogen bottle is removable, making it easy to clean. The cup mouth is equipped with a sealing ring to prevent leakage and ensure better air tightness. Please ensure a good seal of the cup lid during use to avoid water leakage. 4、260ml Capacity: With a size of 60x60x190mm, the hydrogen water cup can hold 260ml of liquid. It is convenient to carry and can easily meet your daily drinking water needs during sports, outings, and work. The glass of the hydrogen water bottle is made of environmentally friendly material, without any harmful substances, ensuring safety for consumption. 5、Health Gift: Using the hydrogen water bottle for healthy hydration provides safe drinking water. Drinking hydrogen rich water in the long term can slow down oxidation reactions, promote metabolism, enhance immunity, and delay aging. The hydrogen water generator cup is an excellent gift for friends and family. Depending on the water quality, commercially available mineral water can be electrolyzed 15‑20 times when fully charged. Note: Do not add juices, milk, tea, distilled water, or purified water that cannot be electrolyzed.
