Three small green circuit boards with red and green input wires and high-voltage output leads

GCON

GCON 3Pcs DC 3.6V-6V to 20kV 1.5A Boost Step Up Module

SKU CH-F8Z0-BC6CG

Three high-voltage boost modules convert 3.6-6 V DC input to 20 kV output for science experiments and negative-ion generators

  • Tesla-coil design delivers 20 kV pulse output for intense arc experiments
  • DC 3.6 V–6 V input runs from single 3.7 V lithium cell or dual 18650 packs
  • 5 A boost capability powers negative-ion generators and high-voltage sources
  • Colour-coded wiring (red positive, green negative) simplifies connection for science projects
  • Compact, high-efficiency module avoids no-load operation to maximise arc distance

GCON 3-Pack High-Voltage Boost Modules

This set contains three identical DC boost modules that convert a 3.6 V to 6 V input into a 20 kV pulsed output rated at 1.5 A. Each unit is built around a Tesla-coil topology and is intended for experimenters, educators and hobbyists who need a compact high-voltage source for science projects or negative-ion generation.

Input Range and Load Constraints

The modules accept a 3.6 V to 6 V DC supply, typically from a single 3.7 V lithium cell or two 18650 cells in series with a capacity of at least 2000 mAh. Operation without a connected load must be avoided, and the high-voltage output leads must be kept at a safe distance from the power source to prevent damage.

Replaces Discrete High-Voltage Assemblies

These modules replace bulky custom-wound flyback or Tesla-coil driver boards that previously required separate oscillators, drivers and transformers. The jump is worthwhile when a ready-to-wire, battery-powered 20 kV pulse source simplifies a classroom demonstration, ioniser prototype or similar low-current high-voltage application.

Questions about this item

How many modules come in the pack?

Three identical boost step-up modules are supplied together, so you can build multiple high-voltage experiments or keep spares for classroom use.

What does the 20000 V output rating mean when the module is powered?

The module produces a 20 kV high-voltage pulse arc from a 3.6–6 V DC source; the actual arc length depends on battery current capability and load distance.

Which DC input range does the boost converter accept?

It operates from 3.6 V to 6 V DC, compatible with a single 3.7 V lithium cell or two 18650 cells in series.
