4A Electronic Load Current Voltage Power Tester USB Protection LCD Display Adjustable Resistance Unloader for Kuvaus

This 4A electronic load module is designed for testing current, voltage, and power of USB power supplies, chargers, power banks, and -based power projects. It supports adjustable resistance load to simulate different working conditions, helping you evaluate stability and performance.
The module allows fine adjustment of load current to 4A (depending model), and adjustable resistance to match various test scenarios. Ideal for debugging and verifying power supplies, USB chargers, and DIY electronics applications.
Equipped with an easy-to-read LCD display, the tester shows real- voltage, current, power, and other key parameters. This helps you quickly monitor output conditions and identify issues such as voltage drops, overloads, or unstable outputs.
The built-in USB protection design helps reduce the risk of damage to your power sources and connected devices during testing. It supports overload and overcurrent protection (depending usage conditions), making long-term testing safer and more reliable.
Please ensure correct connection and do not exceed the specified current, voltage, and power limits during use. Prolonged operation at maximum load should be avoided to ensure long service life and stable performance.
