When the 3V voltage is input, the output is about 1500V, the 3.7V input is about 1800V, and the 4.2V input is about 2000V.
This is a high-voltage, low-current, low-power boost module. If you want to increase the instantaneous discharge current, you can output a large-capacity, high-voltage capacitor in parallel (recommended to use 4 CB65 capacitors for air conditioners and 450V for series connection. Size you choose according to your needs)
The board has a high-voltage capacitor, which may leave excess capacitance after use.
