The Vevor hydrogen water cup uses SPE technology to transform regular drinking water into hydrogen-rich water with a concentration of 1000-1500 ppb. Its 14.1 oz 400 ml borosilicate glass body is designed for single-person use and resists hot and cold temperature changes. The wireless charging base powers hydrogen production and can also charge compatible phones or earphones. Walnut accents and a dishwasher-safe bottle design combine style with everyday practicality. This portable cup is made for convenient use at home, in the office, or on the go.
