As a health product, it' s safer and more convenient. Its round design is simple and elegance. Its core structure is developed independently and adopted the latest SPE electrolysis technology. This multi-purpose generator is 1/3 smaller than other similar products overseas. Though it is only 160g, but it can produce more hydrogen than others. Decompression valve on the cover can prevent the generator from burst when hydrogen pressure is high. Rotational structure of cover means you can rotate 35°to open the cover. The base can connect with mineral water bottle or original bottle. As a product designer, I always try to present the complicated structure by a simple shape. It looks simple, but not simple.
