Note: The products are all hand-filled with glue. They will sink after being placed for a period of time (waiting for the glue to dry). They will not affect the use. They are all processed with glue-filled insulation. Please do not buy if you have special requirements. The appearance is not very nice.

This high-voltage module is made using the principle of the Tesla coil, which outputs high-voltage pulse high-voltage current, is small in size, high in efficiency, and simple in peripheral circuits (just connect the switch and the battery). The discharge intensity is violent.

Regarding the supply: you can use a single 3.7V lithium battery or two in series, such as 18650 batteries, idle mobile phone batteries (with the protection board removed, the recommended capacity is more than 2000mAh) or nickel-cadmium/nickel-metal hydride battery packs, 4V or 6V lead-acid Battery, etc.

This module is a finished module of high-voltage inverter transformer/booster for scientific small production. After inputting DC3V-7.2V voltage at the input end, a DC high voltage of about 200,000 volts (about 1-2 cm arc) can be obtained at the output end. , Note that there is no ignition function.
