【High-Quality Voltage and Current Tester】8A High Current, ARM M4 CPU Equipped with a 32-bit high-speed M4 core, providing smooth operation with no screen lag. Features a 5P pass-through USB male/female connector with full copper contacts. Allows monitoring of voltage, current, power, and temperature data curves, and exporting these curves for analysis or product comparison
【High-Definition Color Screen】0.96-inch full-view IPS high-definition color screen with a resolution of 160x80, featuring an independent opening design. The screen information supports 180° rotation, ensuring clear visibility from any angle
【2MHz High-Speed Ripple Detection】Built-in 2MHz high-speed ripple detection supports measuring the working frequency and ripple of charging adapters, assisting in evaluating the quality of the charger. Ripple value VPP can be used to quickly assess the output quality of the charger
【Charging Assistance Function】This tester includes a low-current charging assistance function, capable of activating low-current charging for devices. Many power banks and some chargers shut down output when the load current is low, which prevents small devices like headphones and watches from charging properly. This tester effectively resolves this issue
【Restores Charger Potential】Some chargers restrict charging speed to 500mA for devices that don't support IP device identification levels. This tester can help the charger reach its full potential, restoring the original charging speed
