Full Product Description

The Health Check Your Electronics Deserve

In an era of "Fast Charging," not all cables and chargers are created equal. The KWS-MX23 USB Tester is the ultimate diagnostic tool for tech enthusiasts, gamers, and professionals who demand optimal performance from their devices.

Precision Monitoring for Every Charge

Plug the KWS-MX23 into any USB port, and it instantly becomes a powerful command center. It visualizes critical data—Voltage (V), Current (A), Power (W), and Capacity (mAh/mWh)—allowing you to identify faulty adapters or inferior cables that could damage your expensive electronics. With support for up to 30V and 12A (Peak), it handles everything from standard smartphones to high-power USB devices.

Vivid IPS Display with Multi-Page Views

Unlike basic testers with monochrome segments, the KWS-MX23 features a crisp 1.06-inch IPS HD color screen. With a single click, you can toggle between standard measurement views, statistical data summaries, and curve measurement interfaces. The 160-degree wide viewing angle ensures you can read the data clearly, no matter how your charger is positioned.

Professional-Grade Data Logging

Don't just watch the charge; record it. This device tracks the total capacity (mAh) delivered over time, making it perfect for verifying the advertised capacity of power banks (external batteries). It also features intelligent power-off memory, saving your data even when unplugged.

FAQ Section

Q: Can this device detect Fast Charging protocols?
A: Yes, the KWS-MX23 supports USB 2.0 data transfer and is compatible with mainstream fast charging protocols, allowing the high voltage/current of fast chargers to pass through for measurement.

Q: Does using this tester affect charging speed?
A: Negligibly. The device is designed with low internal resistance to ensure "straight-through" charging, meaning it measures the power without significantly slowing down the charging process.

Q: Does it save data if I unplug it?
A: Yes, it features power-off memory. The capacity and energy data are stored automatically when power is lost, allowing you to resume accumulation or view the last record when you plug it back in.
