Whether you’re debugging a custom Raspberry Pi build, testing a suspicious charging cable, or optimizing your mobile hacking kit, the KWS-V20 USB Meter is an essential tool for your EDC (Every Day Carry). This compact, "plug-and-play" diagnostic tool gives you real-time visibility into your power rails. Stop guessing if your device is drawing enough current... see it. Each KWS-V20 is equipped to help you in the following real-life use cases: Real-Time Diagnostics: Instantly monitor voltage, current, and capacity to troubleshoot power-hungry peripherals or failing batteries. Phone Health Check: Monitor your smartphone’s intake to see if the battery is throttled or if your fast-charging protocol is actually kicking in. Safety First: Instantly detect voltage spikes or "dirty power" from cheap car chargers or public USB outlets that could fry your expensive hardware. Precision Monitoring: High-contrast digital display ensures you can read your stats even in low-light environments. The "Cable Killer": Use it to identify "fake" fast-charging cables or underperforming wall warts before they slow down your workflow. Total Portability: No external batteries or extra leads required. It draws power directly from the USB port, making it the perfect field tool. Capacity Timer: Features a built-in timer to measure exactly how much juice your power bank holds or how long a device takes to reach a full charge. Usage Tips for Hackers: Use this to verify that your USB Rubber Ducky or WiFi Pineapple is receiving stable voltage when running off a portable battery. It's the fastest way to prevent "brown-outs" during a pentest or field project. Package Includes: 1x KWS-V20 USB Power Tester (Stealth Blue)
