783HZ Schumann Wave Generator Low Frequency Pulse Sinewave Generators Sound Improving Pulse Generator Helps Sleep with USB 7.83HZ Schumann Wave Generator Low Frequency Pulse Sinewave Generators Sound Improving Ultra Low Frequency Pulse Generator Precise Frequency Helps Sleep with USB Feature: 1. 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. 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. 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. 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. 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. Specification: Origin: Mainland China DIY Supplies: ELECTRICAL Material: ABS color: White Power supply: 3.7V, 600mAh built-in lithium battery Micro USB charging with 4 battery indicator lights Power consumption: 5V 0.08A Working frequency: 7.83Hz, sine wave generated by programmable smart chip. Waveform, frequency and power can be set (default is fixed). Higher frequency accuracy and stability consistency. One USB-A for external 5V power Product size: 80.00x75.00x20.00mm Product size: 3.15x2.95x0.79inch Product Description: Schumann electromagnetic waves have low frequency and can penetrate any material. 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. Note: 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. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. 1 x Schumann Generator 1 x USB Cable _x000D_
