See the Power: Diagnose, Test, and Verify Your USB Devices with Precision Unlock the hidden data of your USB ports with the Keweisi KWS-10VA USB Current and Voltage Tester. This powerful, pocket-sized diagnostic tool provides invaluable insights into the performance and health of your chargers, cables, power banks, and connected devices. Move from guesswork to certainty by seeing exactly how much power is being delivered and consumed. Key Features & Benefits: Comprehensive Power Analysis: Get real-time readings on key metrics including Voltage (V), Current (A), Power (W), Capacity (Ah), and Energy (Wh). This allows you to verify a charger's output, measure a power bank's true capacity, and monitor a device's power draw. Bright, Clear OLED Display: The easy-to-read OLED screen provides sharp visibility of all data points simultaneously, even in low-light conditions. It automatically detects and displays the quick charge protocol (like QC2.0/3.0) in use. Auto-Ranging & High Accuracy: With a wide measurement range (0-5A, 3-9V) and high accuracy, the tester automatically adjusts to provide precise readings for everything from a low-power Bluetooth headset to a fast-charging smartphone. Practical Diagnostic Tool: Use it to identify faulty cables (high resistance), test the actual output of chargers, calculate the total energy stored in a power bank (Wh), and diagnose why a device might be charging slowly. Easy to Use & Portable: Simply plug the male end into a USB power source (wall charger, computer, car socket) and the device into the female end. Its compact size makes it a must-have for your tech bag, toolkit, or desk drawer. Ideal For: Tech Enthusiasts & DIYers: Verify fast charging and test gear performance. Phone Repair Technicians: Diagnose charging port and cable issues. Content Creators & Reviewers: Measure power bank capacity and charger output accurately for reviews. Travelers: Check the quality of unknown hotel or airport USB ports. Anyone tired of slow or unreliable charging. Package Includes: 1 x Keweisi KWS-10VA USB Tester 1 x User Manual (often multi-language) Make informed decisions about your electronics. The Keweisi KWS-10VA is the window into your USB power ecosystem, ensuring your devices charge efficiently and safely.
