Item Type: Mini Coil Kit <br>Material: PCB, copper <br>Purpose: Wireless transmission of power, light up fluorescent lamps <br>Input Voltage: DC 9-12V (can be started with a 9V battery, but if there is an arc, the working voltage needs 12V) <br>Input Current: 1A or above (2A recommended) <br>PCB Board Size: Approx. 40 x 31mm / 1.6 x 1.2in<br>1、Coils can transmit electricity wirelessly, light up fluorescent lights, and have a wonderful arc, powerful and practical <br>2、You can use the coil to do a lot of very interesting scientific experiments, helps a lot <br>3、The coil is used to generate high frequency alternating current with ultra high voltage but low current, very stable <br>4、The advantages of coil kit are low noise, high efficiency, and long life, you can use with confidence <br>5、DIY parts can increase hands on ability, including a variety of accessories, easy to useThis 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.<div>1 x Module</div><div>3 x Screw</div><div>3 x Standoff</div><div>1 x LED Light</div>
