Review on H2CAP Set Package 30mm - Real Molecular Hydrogen Rich Water Ionizer Maker Bottle with Platinum Dual Chamber Technology Certified by Japan Hydrogen Water Promotion Association by Brittany Hamilton

So far so good. Comes with USB cable and carrying case. The actual size of the cap is palm-sized, portable yet very powerful. I photographed the hydrogen bubbles compared to the old car I had (assuming my old car is 3 years old) and there are a lot more hydrogen bubbles being generated with h2cap. Minutes of operation produced 1900 ppm hydrogen. I did a second test with new water: 2 runs, then opened the lid to release the pressure, then ran a 3rd time for a total of 15 minutes. The water was tested at 2100ppm hydrogen so the difference is not much more than 2 runs. I think the natural pressurization of the hydrogen in the bottle is necessary to force the hydrogen into the water if you want higher concentrations of hydrogen, but I didn't want to run it 3 times without depressurizing in case it damages the car. So I think 2 runs will produce enough hydrogen for 500ml of water. My old generator could only produce 1400ppm of hydrogen in 10 minutes from just 300ml of water. Benefits and best results at 2000-3000 ppm per 32 ounces of water for all serious conditions, so 2 x 10 minute bottles of h2cap daily provide significantly more than this amount for therapeutic benefit. The only downside of this device is that you need an external power adapter for USB power and you have to disconnect and reconnect it to start a new round of generations. Maybe it would be better if they put a button to start
