Hydrogen Water Bottle: Utilizes electrolysis technology to help infuse water with hydrogen. This portable hydrogen water generator quickly electrolyzes water to produce hydrogen-rich water, which may support antioxidant activity and reduce oxidative stress. Designed for everyday use, it delivers water with high hydrogen concentration and stable performance.High Efficiency: Produces hydrogen-enriched water in approximately 3 minutes. The electrolysis efficiency and resulting hydrogen content may increase with higher mineral content in the source water. (Do not use water above 60C, as high temperatures may cause hydrogen to dissipate during cooling.)Improved Water Quality: With a short electrolysis cycle and consistent output, this device is compatible with various drinking water sources. It helps minimize residual gases after electrolysis, contributing to safer and more enjoyable drinking water.Sleek and Portable Design: Features a secure cup cover with buckle closure for better sealing and ease of use. Rechargeable via USB, the compact design makes it convenient for travel, work, or fitness activities.Ideal Gift Choice: Simple one-button operation makes it easy to use at the office, at home, or on the go. A thoughtful gift for holidays such as Birthday, Thanksgiving, Christmas, New Year, or Anniversary.Note: Slight color variations may occur due to lighting or screen differences.
