["brand new and high quality\n\nFeatures:\nfor DC 3.7V Boost 1800V, Pulse Boost Module\nCan work continuously, the maximum discharge distance is about 1.5MM\nInput voltage: 3-4.2V\nInput current: up to about 2A\nNo-load current: 130MA (4.2V voltage)\nOutput voltage: 1800V (battery voltage is low, output voltage will also become lower)\nDimensions: 2.6x4.1cm/1.02x1.61inch\nColor: As shown\nQuantity: 1 Pc\n\nPrecautions:\nWhen the 3V voltage is input, the output is about 1500V, the 3.7V input is about 1800V, and the 4.2V input is about 1800V.\nThis 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)\nOutput circuit is voltage doubler rectifier.\nWith high voltage discharge capacitor, 1800V 223.\nThe board has a high-voltage capacitor, which may leave excess capacitance after use.\nHigh pressure danger, use need to pay attention to safety.\n\nPackage includes:\n1 x Voltage Booster Module (without retail package)"]
