Review on N.P Hydrogen Water Bottle Generator: Advanced PEM and SPE Technology, Up to 1500PPB, Portable Hydrogen Water Maker - Black by Andrea White

Excellent product although I sent it back. It makes hydrogen water in minutes. Great device to stay at work or on the go and stay hydrated. It charges the internal lithium-ion batteries via the USB port and takes about a couple of hours to fully charge. Once fully charged, it can deliver 10-15 glasses of hydrogen water. It is inconvenient to use at home because several family members will drink the hydrogen water. You have to wait 2-3 minutes before you can get a glass of hydrogen water. Just one glass at a time. The battery is empty after 10 glasses and does not produce hydrogen water when charging via USB. Home use requires more capacity and the ability to plug it directly into an outlet.
