USB Protector Tester For V3, 300V High Voltage Pulse Analyzer, USB Killer Device for Withstand Voltage Testing of Computers and Electronics, Professional Voltage(without casing)

• [COMPACT USB VOLTAGE TESTER] This innovative device requires no external power source and operates directly from a USB interface, making it incredibly user-friendly. Simply it in and monitor the pulse voltage output effortlessly.
• [HIGH VOLTAGE CAPABILITY] With an impressive output voltage of 300V and maximum pulse current exceeding 1kA, this tester is designed for serious applications, you can safely analyze high-voltage environments.
• [QUICK CHARGING TECH] The supercapacitor charges fully in just 2 seconds, allowing for rapid testing of devices to they can withstand high voltage without damage.
• [SOUND INDICATION FEATURE] A slight operational for sound signals the discharge control process, providing audible that s the tester is functioning correctly during use.
• [SIZING REMINDER] Please your USB interface meets the input requirements of 5V and 1A for optimal performance. Refer to your device specifications rather than Amazon's sizing chart.

Features: This product is a test instrument that continuously outputs pulse voltage based on a switching boost structure. Its input energy is taken from the output of the USB interface itself (5V 1A or higher), therefore charging is not required. It has requirements for the output capability of the USB interface: output voltage of 5V with an error of no more than 20%, and current output of no less than 1A. Otherwise, the product may malfunction. This product may emit a slight sound during ; the sound originates from the current noise generated by the discharge control element. Computer Tester (If the computer does not explode after being plugged in, it indicates that the interface can withstand 300V, meaning it is a good computer.) Working Principle: After plugging in a mobile phone or computer, it quickly charges the supercapacitor, fully charging it in approximately 2 seconds, and then instantly returns a 300V high-voltage current.
