H2CAP Technical Specification
Everything measured, nothing exaggerated. H2CAP has a hydrophilic platinum PEM — when idle for several days, keep a little water inside and the cap closed.
Portable Hydrogen,
Anywhere You Go
H2CAP Plus turns almost any standard bottle into hydrogen-rich water in about 3½ minutes — no installation, no bulky base, and no internal battery to replace.
- Fits standard 30 mm bottles — take it anywhere
- USB-C powered — charge from any power bank
- Food-grade, BPA-free Tritan — safe, durable build
How to Choose the Best Hydrogen Water Bottle
Beyond portability, weigh six factors before you buy — or before you stock a shelf.
H₂ Concentration (ppb)
Most positive research uses 1,000–1,600 ppb. Below 500 ppb may not match published protocols. Verify with a reagent test kit.
SPE / PEM Technology
Only SPE/PEM fully separates H₂ from O₂ and eliminates ozone/chlorine. Basic electrolysis cannot achieve this.
Materials Safety
Require BPA-free, food-grade materials and platinum-coated titanium electrodes — not stainless steel that can leach.
Power & Longevity
Internal Li-ion cells degrade in 12–18 months. USB-C devices with no internal battery last far longer.
Universal Compatibility
A universal 30 mm neck fit means one device works across standard bottles — not locked to one proprietary vessel.
Wholesale Readiness
Documentation, MOQ pricing, and co-marketing support matter for B2B buyers building a sustainable retail line.
