Features: 1.Classic spark gap Tesla coil, very interesting 2.WHY call it a classic? Because Nikola Tesla originally invented the Tesla coil with this structure, using a spark gap to trigger the work of the resonant circuit. 3.Before semiconductor devices were born at that time, it was this form of Tesla coil 4.The Tesla coil adopts the primary coil of the circuit board, which saves trouble and is beautiful 5.The ceramic gas discharge tube replaces the classic spark gap Tesla coil of the air lighter, and the core components are innovated with new technology Notice: Actual color may be slightly different from the image due to different monitor and light effect Please allow 1-3cm deviation due to manual measurement Description: Power supply: 110-240VAC 50/60H2 Power: 0-120W Lightning length: 0-10cm adjustable by the knob Host size: 106*106*58mm Logistics size: 210*120*150mm Package List: 1 x Coil Kit
