Why Does My Echo Flask™ Feel Warm To The Touch?

If your Echo Flask™ feels warm while in use, don’t worry—it’s perfectly normal. Here’s why:

• The Circuit Board: The flask’s circuit board on the screen side generates a small amount of heat during operation. This is completely safe and simply part of the device’s normal function.
• Battery Operation: The 2000mAh lithium-ion battery powering your flask can also generate warmth as it works to generate hydrogen efficiently.

This warmth is a sign that your flask is working as it should, bringing you the best hydrogen-rich water experience.
