The pen-shaped design and portable size convenient to carry and use daily. This capacitor discharge pen supports 5000UF capacitor discharge, which can quickly discharge the residual power of high-voltage capacitors, but cannot be used for battery discharge. It can quickly discharge the residual power of capacitors generated by electronic products (such as switching power supplies, digital cameras, mobile phones, etc.) during production, testing and maintenance protecting operators from and product damage. The discharge pen can automatically and intelligently identify the discharge time, without distinguishing electrodes, and the discharge is constant and spark-free. With LED indicator light, the indicator light is on to indicate that the discharge is in progress, and the voltage is about 9V when the indicator light is off, and the discharge is completed.
