1. Ultra-long battery life, using a safe 3.7V 2000mAh lithium battery, charging for about 3 hours, can be electrolyzed 15 times after fully charged, and each working time is 10 minutes 2. Touch the switch screen, the hydrogen production time can be seen 3. divided, easy to clean 4. Dual-use stainless steel cup cover, effective discharge and filtration of 5. Double-layer glass cup, heat insulation and not hot 6. Hydrogen production is about 1300, easy to use 7. High borosilicate glass body, cold and heat resistant, with olecranon spout, fluid flow 8.8cm large-caliber spout, easy to clean 9. Separate hydrogen and oxygen to discharge chlorine and ozone. The residual ozone and chlorine produced during hydrogen production are separated from here to improve the concentration and purity of hydrogen production. The hydrogen vapor produced during the discharge is stored in the storage drawer and can be sucked out and discarded. Capacity: 1000ML Color: White Material: metal + glass Package
