Portable Power Solution: The Schumann Wave Generator comes equipped with a built-in lithium battery and includes a micro USB cable for convenient charging. With its four-light power indicator that blinks during charging and a low energy consumption of 5V, 0.08A, this device ensures long-lasting use on the go._x000D_ _x000D_ _x000D_ 2. Precision Engineered Waves: Our Low Frequency Pulse Sinewave Generators produce sine waves through a programmable smart chip, operating at a fixed frequency of 7.83Hz. This offers higher frequency precision and stability, allowing for customizable waveform, frequency, and power settings to suit your needs._x000D_ _x000D_ _x000D_ 3. Versatile Power Output: Featuring a USB output port, the Ultra Low Frequency Pulse Generator can also serve as a 5V power source. This makes it not only a generator of beneficial frequencies but also a convenient power supply for other devices._x000D_ _x000D_ _x000D_ 4. User-Friendly Design: The Schumann Resonance Pulse Generator simplifies operation with a click switch to power on/off and display battery level. A long press of the switch for 5 seconds turns off the output, making it user-friendly and efficient._x000D_ _x000D_ _x000D_ 5. Wide Application: Designed for versatility, the Pulse Generator enhances audio-visual spaces by improving sound fields and visual effects, offers relief from insomnia in bedrooms, and reduces stress and anxiety in offices, helping to relax and improve work efficiency._x000D_ _x000D_ _x000D_ Specification: _x000D_ Origin: Mainland China _x000D_ DIY Supplies: ELECTRICAL _x000D_ Material: ABS _x000D_ color: White _x000D_ Power supply: 3.7V, 600mAh built-in lithium battery _x000D_ Micro USB charging with 4 battery indicator lights _x000D_ Power consumption: 5V 0.08A _x000D_ Working frequency: 7.83Hz, sine wave generated by programmable smart chip.

There is a weak current network in each human body. When Schumann waves are stimulated, frequency resonance will occur. By receiving the Schumann electromagnetic field and human cell frequency resonance, it maintains the overall balance of the human body's meridians, thereby reducing the damage caused by EMF ionizing radiation to the human body. It can induce human body frequency resonance, supplement natural geomagnetic and artificial attenuated electromagnetic field EMF interference, and make the membrane potential balanced and healthy. _x000D_ _x000D_ _x000D_ Note: _x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
