Specification: brand new and high qualityMaterial: Electrical componentsColor: As shown in picturesTesla on the basis of the general increase of the music player, you can play phone / computer music, a clear sound. 1524 V DC input voltageWhen 24 V, 510mm arc length meters is ideal, small size, power range and power, can be a long working Energysaving lamps, frequency flash tube, you can play power transmission wireless, rotary arc and so on.Parameters:Size: 38 * 79mmPower: 15 wPower Input: DC 1524V, Current 2A, DC5.5 InterfaceAudio input: 3.5 jack, you can connect your phone, mp3, computer audioPlasma speaker stereo speakers: the principle is to stimulate the plasma arc of air turned into air vibrations generated by the expression of a new concept, you can access your phone, mp3, computer audio input, this mini speaker Tesla plasma arc speaker compared to the actual real experience better sound highfrequency response, and spark plasma arc speakers have good sound quality, stable and safe, you can play any song without earthing, easy to Use resources compared; There is no doubt as a new member stereo home playerPrinciple of wireless transmission: a coil connected at both ends with both ends LED, nearemitter device, Qiliang LED, the principle is resonant wireless power transfer Precautions:1. Product safety, power is not high, not because of an electric shock, but is not recommended to touch the top of the arc coil, there will be a burning sensation.2. After a long time the power does not touch the heat sink, the temperature is very high, especially when using a huge 24V highvoltage heat, reserve a fan interface, plus cooling fan if necessary.3. It is not recommended to work on the body or other objects near the coil Tesla coil, the coil within half a meter next to other objects can not be left blank, because other objects such as a good conductor coil will form a good Loop, coil to absorb energy, then pull the coil or unable to Water demonstrate the effect of the demo variationplease, note;4. Not for the phone, mp3 and other electronic equipment near the coil, the coil generates a high frequency magnetic field would interfere with these mobile phones, mp3 and other equipment failure or damagePackage Included:1X DIY15W Mini Speaker Music Tesla Coil Kits(NO Include Stainless Ball)
