<p>1. PROGRAMMABLE FREQUENCY GENERATION: The Schumann wave generator produces precise and stable frequencies using a programmable generator.</p> <p>2. MULTIPLE POWER SETTINGS: With 3 power levels, the low-frequency pulse generator allows adjustment according to individual preferences, with a maximum output power of 5W.</p> <p>3. MINIMAL HARMONIC DISTORTION: Unlike similar products on the market, our Schumann wave generator uses fewer harmonics, resulting in a purer sine wave output.</p> <p>4. LED POWER INDICATOR: The built-in LED indicator displays the power levels, with low, medium, and high settings represented by L, M, and H respectively.</p> <p>5. LONG BATTERY LIFE WITH USB CHARGING: Equipped with a built-in 3.7V 4000mAH lithium polymer battery, the pulse generator offers a long standby time and can last up to 8 hours of continuous operation at maximum power. It also supports USB charging and comes with a Type-C charging cable.</p> <p>Colour:As Shown</p> <p>Material:Plastic</p> <p>Item Type: Schumann Wave Generator</p> <p>Rated Current: 0.5A</p> <p>Maximum Power: 5W</p> <p>Signal Waveform: Pure Sine Wave</p> <p>Power Indicator: Adjustable in three gears (L, M, H)</p> <p>Battery: 3.7V 4000mAH lithium polymer battery x 1 (shipped with built-in battery)</p> <p>Battery Life: Maximum power for continuous operation of up to 8 hours</p> <p>How to Use:</p> <p>1.
