Multifunctional High Frequency EMP Generator Electromagnetic Pulse Generator Fingerprint Lock Detector LightBulb Detector<br> The EMP Generator produces a high-frequency electromagnetic waves field. An energy-saving lamp around the generator induces electromagnetic waves and generates an electric current. When the electric energy is sufficient, the lightbulb will light up. It can also be used to check the quality of fingerprint locks.<br> Features:<br> Compact size for easy carrying and operation.<br> It can be used to check the quality of lightbulbs or fingerprint locks.<br> Plug-in emitting heads, triode can switch by yourself.<br> The coil can be adjusted by yourself. If the coil is reduced, the power will be reduced, otherwise, the power will be increased.<br> High frequency power, fine effect, more stable.<br> Window opening design for quick heats dissipation.<br> Stable and long-lasting power, the chip is not easily damaged.<br> The voltage can be observed for timely recharging.<br> Specifications:<br> Plug: US-plug, EU-plug (optional)<br> Main color: black, white (optional)<br> Material: ABS<br> Battery: 3.7V, 250mAh<br> Host size: 80 * 43 * 24mm / 3.1 * 1.7 * 0.9in<br> Package size: 110 * 105 * 65mm / 4.3 * 4.1 * 2.6in<br> Package weight: 182g / 6.4ounce<br> Packing List:<br> 1 * Electromagnetic Pulse Generator<br> 1 * Power Cable<br> 1 * User Manual<br> 2 * Coil<br> 1 * Triode
