Feature:1. Coils can transmit electricity wirelessly, light up fluorescent lights, and have a wonderful arc2. You can use the coil to do a lot of very interesting scientific experiments, very useful3. The coil is used to generate high frequency alternating current with ultra high voltage but low current4. The advantages are low noise, high efficiency, and long life, you can use with confidence5. DIY parts can increase hands on ability, including a variety of accessories, very practicalSpecification:Item Type: Mini Coil KitMaterial: PCB, copperPurpose: Wireless transmission of power, light up fluorescent lampsInput Voltage: DC 9-12V (can be started with a 9V battery, but if there is an arc, the working voltage needs 12V)Input Current: 1A or above (2A recommended)PCB Board Size: Approx. 40 x 31mm / 1.6 x 1.2in.Package List:1 x Module1 x Coil1 x Inductance1 x LED Light1 x Switch1 x Power Interface1 x Heat Sink
