Item Type: V3 USB Killer Material: ABS Required Input: 5V, 1A Output: 500V pulse with an average frequency of 4Hz (discharges per second) 1USB KILLER 3.0: Our new version of USB Killer addresses the instability problem of the V2.0 extension cord. Tested with a 5 meter long cord, it still packs a punch. Say goodbye to wrist fatigue. 2IMPROVED DURABILITY: The upgraded version of USB killer features enhanced production techniques, making it far less prone to capacitor breakage and damage. 3USB STRESS TESTING MADE EASY: Designed for USB interface pressure testing, this USB killer is a pulse voltage testing instrument that utilizes a switch boosting structure for sustained output. It draws power from the USB interface itself (5V 1A or higher output), eliminating the need for charging. However, it requires the USB interface to meet the output capabilities of 5V voltage with an error margin not exceeding 20% and a minimum current output of 1A. 4WIDE COMPATIBILITY: Ideal for conducting endurance tests on any smart device with a USB interface (computers, TVs, music players, time clocks, etc.). Also suitable for cell phones with OTG functionality. 5RELIABLE AND EFFECTIVE: This USB pulse generator delivers consistent and accurate results, ensuring that your USB devices can withstand the challenges of everyday usage.1. Portable batteries, mobile phone chargers, public charging stations, etc., are mostly ineffective. Danger of damage, please test carefully. 2. Short circuit test, do not continuously short circuit for more than 20 seconds, otherwise it will be damaged by high temperature. 3. High output voltage, do not touch. 4. This product may make a slight sound during operation. The sound is derived from the current sound generated by the discharge control factor.1 x V3 USB Killer
