Feature:1. Coils can transmit electricity wirelessly, light up fluorescent lights, and have a wonderful arc, powerful and practical2. You can use the coil to do a lot of very interesting scientific experiments, helps a lot3. The coil is used to generate high frequency alternating current with ultra high voltage but low current, very stable4. The advantages of coil kit 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, easy to useSpecification: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 Module4 x Screw4 x Standoff1 x LED LightNote:This coil will send a large amount of unseen current to the surrounding local environment. Although it is certainly not dangerous to humans, it will actually damage sensitive electronic products within half a meter. Therefore, be sure to keep this in mind when supplying power to the coil, and keep your cell phone, camera, MP3 player or any other sensitive electronic products at least 1 meter away.
