Compared to other tesla modules, this product has a protective outer shell to prevent coils from loosen and damaged.2. This product belongs to the PLL SSTC of tesla. Compared with DRSSTC, it can play music in any format, and make sound through the vibration of arc.3. This tesla also has excellent effect, can light up a variety of air. This music tesla can light fluorescent lamps, glow lights, neon lights, LED lights and various gas lamps.4. Easy Operation: Doesn't need to grounded. No manual needed at all. PLUG and PLAY out of the box!5. Long Lasting: This tesla coil is safe, special heat dissipation device, good heat dissipation effect, can work for hours on end. How to Use? 1. Assemble the electrode needle. 2. Connect one end of the adapter to the socket, the other end to the DC joint. 3. Connect one end of the audio cable to smart phone or computer, the other end to circuit board. (Suggest volume: 80%-95%) Attention: 1. Electrode needle must be assembled before power on. 2. The frequency of the coil makes a strong interference of the surrounding electronic products. Not suitable for people who implants with electronic medical instruments. 3. When working, please don't touch the electrode with your hands, it will burn the skin. 4. Please do NOT hold the coil while moving the tesla. 5. Please do NOT touch the electrode, heat sink, circuit board and the copper part
6. Please do NOT use any conductor to touch the secondary coil, or the tesla will be damaged. 7. Please do NOT use this tesla under environment with flammable and explosive materials or closed coil and big size metal. 8. If the tesla failed to start successfully at first of power on, please gently touch the discharge tip by a screwdriver with insulation, but do not touch it for a long time , it may burn the tesla.  Package Included: 1 x Assembled Tesla Coil
