Feature: 1. Hydrogen Production: This hydrogen water bottle uses advanced technology to quickly generate hydrogen ions up to 1200‑1400ppb (1.2ppm) in a single cycle, transforming ordinary drinking water into alkaline water rich in hydrogen ions, reducing oxidative stress. 2. Durable Material: The hydrogen water generator is made of aluminum alloy and high borosilicate glass, which is safe and healthy, the nanoscale ti film material greatly extends the service life, and the 410ML large capacity meets the needs of the entire family. 3. Built in Battery: This hydrogen rich water machine has built in 700mAh rechargeable lithium battery, ensuring long term and continuous use, reducing frequent charging, and is equipped with a USB cable for charging. 4. Multiple Usages: Hydrogen water can reduce oxidative stress, delay aging, enhance the immune system, promote metabolism and nutrient absorption, promote muscle recovery, improve memory and sleep quality. 5. Convenient Use: This portable hydrogen water generator is convenient to use, the bottom EVE pad provides good stability and non slip effect, which can be given to family and friends on birthdays, holidays, or anniversaries. Specification: Item Type: Hydrogen Water Generator Hydrogen Production: 1200-1400ppb Working Time: 3 Minutes Battery: 1 x 700mAh Rechargeable Lithium Battery (included) Product Capacity: 410ml. Package List: 1 x Water Bottle 1 x Hose 1 x USB Cable Note: For better electrolytic effect and higher hydrogen content, please use electrolyte water, such as spark water, alkaline water, mineral water, and the pure water, distilled water and other electrolytic effect will be less.
