Echo Flask User Manual

Meet The Echo Flask™

Inside every Echo device is special technology that turns normal water into hydrogen-rich water.

At the center is the Echo Hydrogen Generator. It uses two titanium plates coated with platinum and a thin proton exchange membrane between them. These laboratory-grade materials are chosen because they are strong, clean, and safe. 

The proton exchange membrane was first made for NASA. Today, it's used in hydrogen cars and other advanced machines. It lets pure hydrogen gas mix into your water while the oxygen is released into the air.

Our carefully shaped plates make sure the electric current spreads evenly, without heat or damage. That means the Echo Hydrogen Generator makes hydrogen faster and more efficiently.

Every part is built from laboratory-grade materials and made to last a long time, so you can always count on clean, high-quality hydrogen water.

Important Safety Information

Do not microwave, refrigerate, or freeze the Echo Flask™

Do not submerge or place in the dishwasher

The Flask™ contains a small amount of distilled water to keep the membrane primed. (This water is NOT for consumption.) Your Flask™ is clean and ready to use.

When first using the Flask™, it may take up to one week of regular, consistent use for your flask to build full pressure and produce consistent hydrogen bubbles.

How to use your Flask™

  1. Fill the Flask™ to the top of its shoulder with water. We recommend purified or distilled water for the best performance

  2. Secure the cap by applying downward pressure while twisting until it clicks and locks into place. 
    • The Echo Logo should sit horizontally or vertically. The cap locks every 90 degrees.
  3. Swipe up on the Flask™ screen and press the play button to activate the hydrogen infusion cycle.

     

    Your Echo Flask™ is designed to automatically manage internal pressure during and after each hydrogen cycle. Because of this, you may hear different sounds or none at all.

    Sound variation does NOT affect hydrogen concentration (PPM).

    When the cycle ends, press the dot on the cap to release pressure before opening. You may experience different sounds depending on how much pressure remains:

  4. Twist off the cap by gripping the sides of the lid, pressing downward on the sides (not on the pressure release, this is after you've already released the pressure) and twist counterclockwise, applying gentle force, similar to opening a pill bottle.

    Small drips from the oxygen port are normal and typically resolve after several uses. This is not considered a leak—it’s an occasional and expected result of oxygen being expelled through the port (even beyond the first use).


     

Your Echo Flask™ is designed to run 5–7 cycles of 10 minutes or 3–4 cycles of 20 minutes per full charge.

When to Charge

For optimal battery health, it’s best to let the battery fully discharge before recharging — allow the Flask™ to run until it can no longer complete a full cycle.

How to Charge

  1. Locate the Charging Port

    • The port is located under the display screen on the generator.

  2. Connect the Charger

    • Plug the USB-C cable into the generator’s port.

    • Connect the other end to a 5 V, 2 A charger block (any compatible USB-C or USB-A adapter works).

  3. Charge Fully

    • Allow up to 2.5 hours for a complete charge.

    • Your battery indicator may show green with full bars after a few minutes, but the battery still needs the full charge time to reach optimal capacity.

  4. Monitor Charging

    • Avoid overcharging or leaving the Flask™ plugged in continuously, as this can reduce long-term battery life.

  5. Unplug After Charging

    • Once fully charged, unplug the Flask™ to prevent potential battery damage, overheating, cord damage, or fire risk.
