Feature: 1. SPE and PEM Technology: Utilizing SPE and PEM technology, the hydrogen water bottle rapidly electrolyzes water, separating and releasing H2 and O2. It helps convert ordinary drinking water into alkaline water rich in hydrogen ions, effectively reducing oxidative stress. With high hydrogen concentration and excellent stability. 2. High Efficiency: Only 3 minutes needed for quick electrolysis and water quality transformation. During the three minute electrolysis process, a higher mineral content in the water leads to strong electrolysis and higher hydrogen content. Do not use water above 60 degrees, as high water temperature during hydrogen generation may cause hydrogen loss if the cooling process takes too long. 3. Water Quality Improvement: The hydrogen rich water generator has a shorter electrolysis time and more stable parameters, suitable for all drinking water qualities. It effectively addresses residual hydrogen and oxygen issues after electrolysis, ensuring safer and healthier drinking water. 4. PCTG Material: The cup body is made of premium PCTG material, which is safe and free from BPA. It is heat resistant, durable, and features an EVE pad on the base for stability and non slip function. 5. Portable Charging: The hydrogen water bottle is designed with a cup lid buckle, ensuring better sealing and easy operation. It is USB rechargeable for convenient use. With its small and compact size, you can easily carry it in your bag, making it a big step towards healthy drinking water.
