Hydrogen Water Bottle 320ml | 1500-4000ppb

Hydrogen Concentration Modes

The bottle offers two operating cycles to match your hydrogen intake goals:

• 5-minute mode: Produces 1500–3000 ppb hydrogen concentration for quick, moderate enrichment
• 10-minute mode: Generates 2000–4000 ppb for maximum hydrogen content and enhanced antioxidant potential

Both modes create visible microbubbles during electrolysis, indicating active hydrogen production.

How It Works

The CA-308 uses water electrolysis to separate hydrogen and oxygen molecules. Ion-permeable membrane technology ensures efficient hydrogen dissolution while oxygen is released through the pressure relief valve at the base. During operation, small bubbles form at the electrode and rise through the water, dissolving hydrogen into the liquid.

What’s Included

• 1 × Hydrogen water bottle (320ml)\
• 1 × Magnetic charging cable
• 1 × User manual
• 1 × Power adapter (optional)
• 1 × Bottle adapter for standard mineral water bottles (optional)

Water Compatibility

For optimal performance and device longevity, use water that meets Sanitary Standards for Drinking Water Production:

• Bottled or canned mineral water (recommended)\
• Distilled water
• Purified or filtered drinking water
• Water temperature must remain below 60°C to prevent component damage.

Do not use turbid water, heavy-metal contaminated water, or conductive liquids.

Daily Use & Maintenance

• First-Time Setup: Remove the sealing cap from the electrolyzer inside the bottle, pour out any moisturizing liquid, rinse 1–2 times with drinking water, then run two electrolysis cycles and discard the water before regular use. Fully charge the battery until the green light appears.
• Pressure Management: Gas generated during electrolysis creates internal pressure. After each cycle, lift the silicone plug at the base to drain accumulated water and release pressure before placing the bottle in your bag.
• Cleaning: If white scale builds up, soak the bottle with vinegar or citric acid in warm water, then rinse thoroughly. Keep the ion membrane moist when not in use for extended periods by storing the electrolyzer in pure water. Prolonged drying may cause membrane failure.
• Consumption: Drink hydrogen water promptly after electrolysis or open the lid to release pressure, as hydrogen naturally dissipates over time.

Portable Adapter Option

The included bottle adapter allows the CA-308 base to be attached to standard mineral water bottles. When using this option, operate only the 5-minute mode once per bottle to avoid excessive internal pressure that could cause breakage.

Safety Features

• Automatic shutoff after cycle completion
• Pressure relief valve to prevent over-pressurization
• Temperature protection (safe up to 60°C water input)
• Battery protection circuitry
• Food-grade materials in contact with water

Warranty & Support

The CA-308 includes a one-year warranty covering manufacturing defects. Warranty does not cover damage caused by improper use, failure to follow maintenance instructions, accidents, natural disasters, use of non-approved parts, or normal wear on consumable components.

Who Should Use This Bottle

The 320ml hydrogen water bottle is ideal for individuals seeking maximum hydrogen concentration in a portable format, including athletes supporting post-exercise recovery, wellness enthusiasts seeking antioxidant-rich hydration, frequent travelers, and users looking to incorporate hydrogen water into their daily routine.

Operating Tips

When the ion membrane is new and dry, initial cycles may produce fewer bubbles and lower hydrogen concentration—this is normal. Run several cycles, use 80°C hot water to accelerate membrane permeation, or fill the bottle halfway and let it sit for 8–24 hours to fully hydrate the membrane.

The LED indicator shows device status. Charge the bottle when the light signals low battery and ensure sufficient power before operation.

Frequently Asked Questions

How long does it take to make hydrogen water with the 320ml bottle?
The CA-308 offers a 5-minute cycle producing 1500–3000 ppb and a 10-minute cycle producing 2000–4000 ppb hydrogen concentration. The device shuts off automatically after each cycle.

How much hydrogen concentration does this bottle produce?
Depending on the selected mode, the bottle produces between 1500 ppb and 4000 ppb of hydrogen-rich water.

What type of water should I use?
Use bottled mineral water, distilled water, or purified drinking water. Avoid turbid, heavy-metal contaminated water or water above 60°C.

How long does the battery last?
The polymer lithium battery (8.14 Wh) charges in approximately 3 hours using a 5V–2A power source and supports multiple electrolysis cycles per charge.

Why is there water at the bottom after use?
Internal pressure during electrolysis causes water accumulation in the base chamber. Drain it using the silicone plug before storing the bottle.

How do I clean and maintain the bottle?
Soak with vinegar or citric acid if scale appears. Keep the ion membrane moist when unused for long periods to prevent damage.

Can I use regular mineral water bottles?
Yes, with the included adapter. Use only the 5-minute mode once per bottle to avoid excessive pressure.

When should I drink the hydrogen water?
Drink immediately after production for maximum hydrogen retention.

Why are there fewer bubbles during early use?
A dry ion membrane needs hydration. Run multiple cycles or hydrate the membrane for optimal performance.

Is hydrogen water safe to drink?
Yes, it is safe and produced using food-grade materials. Do not consume ozone water if generated.

What’s the difference between 5-minute and 10-minute modes?
The 5-minute mode is for quick daily hydration, while the 10-minute mode provides maximum hydrogen concentration.

How do I know when to charge the bottle?
The LED indicator signals low battery. Charge until the green light appears.

Can I use hot water?
No. Water temperature must remain below 60°C.

What does the warranty cover?
The one-year warranty covers manufacturing defects only. Improper use, accidents, and non-approved parts are excluded.

How portable is the bottle?
The CA-308 weighs approximately 495g and measures 66.8 mm × 228.5 mm, fitting easily into bags and cup holders for daily portability.
