3x 7.83hz Programmable Schumann Wave Generator Ultra-low Frequency

1. Schumann wave electromagnetic wave is extremely low frequency, can penetrate any substance, is non-free radiation.2. Schumann wave is a natural energy source, and it is inexhaustible. Anyone who is easy to with Schumann wave is always obtain energy, and the natural spirit is full and healthy.3. Through the resonance of the accepted Schumann wave electromagnetic field and the cell frequency of the human body, the overall balance of the human meridian is maintained, thereby reducing the damage caused by EMF free radiation.4. When the natural regenerative magnetic field is simulated by electronic means, such as using a square wave generator to generate an artificial 7.83 Hz Schumann wave frequency instead of a natural Schumann wave.5. The generator can induce human body frequency resonance, supplement natural geomagnetism and artificially weaken electromagnetic field EMF interference, and make cell membrane potential balance health.Specification:Item Type:Schumann Wave Generator Supply:Built-In Lithium Battery-USB Charging,with 4 Light Battery Display Consumption:5V 0.08AWorking Frequency:7.83Hz, a sine wave is generated by a programmable intelligent chip. Waveform, frequency, and can be set (fixed by default). Higher frequency accuracy and stability consistency.Another USB-A for External 5V SupplySize:80 x 76 x 24mm / 3.15 x 2.99 x 0.94incolor: WhiteMaterial: PU+plasticPackage Contents:3 x Schumann wave generator3 x USB cableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
