Feature: 1. Hydrogen Water Generator: With SPE and PEM technology, this hydrogen water bottle can quickly produce up to 1200ppb (1.2ppm) of hydrogen ions in one cycle, helping turn ordinary drinking water into alkaline water rich in hydrogen ions and reduce oxidative stress. 2. Borosilicate Glass: Hydrogen water generator features a sealed lid design for better sealing, an EVE cushioned base for stability and slip resistance, and is made of food grade borosilicate glass and rubber, no any harmful chemicals. 3. Fast Electrolysis: Just 3 minutes to change the water quality with high mineral content resulting in higher hydrogen content. The process separates and releases O2 and H2, removing residuals ozone to help turn ordinary drinking water into alkaline water rich in hydrogen ions, effectively reducing oxidative stress. 4. Easy to Use: Hydrogen water bottle generator equipped with one key start/stop function and anti slip pad, making it convenient to use in various environments, such as gym, workout, and outdoor. 5. Reusable and Eco friendly: The hydrogen water generator is rechargeable and can be used 15‑20 times when fully charged. It has a capacity of 420ml and works for 3 minutes per cycle, providing you with hydrogen water wherever you go.
