Features 1、USB KILLER 3.0: Our new version of USB Killer addresses the instability problem of the V2.0 extension cord. 2、IMPROVED DURABILITY: The upgraded version of USB killer features enhanced production techniques, making it far less prone to capacitor breakage and damage. 3、USB 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. 4、WIDE 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. 5、EFFECTIVE: This USB pulse generator delivers consistent and accurate results, ensuring that your USB devices can withstand the challenges of everyday usage.
