Features: 1. Two different hydrogen concentration concepts ensure that high concentration hydrogen water of 800-1200 ppb is obtained within 3 minutes which is easily absorbed by the human body and promotes metabolism. 2. Portable drinking bottles are made of high-quality food grade borosilicate glass and can be activated by pressing the bottle button. 3. Healthy drinking water bottles contain biological minerals that react positively with hydrogen-rich aquatic products and remove impurities in water including heavy metals fluorides and bacteria. Hydrogen-rich water can capture free radicals improve energy level and immune system and slow down aging process. 4. Hydrogen-rich ion generator suitable for distilled water purified water mineral water and tap water. It is suitable for producing hydrogen-rich water anytime and anywhere. 5. USB cable can be charged and used 12 to 15 times after being fully charged. Easy to use in office travel and work.
