AT35 USB 3.0 Voltage & Current Meter Tester

AT35 USB Tester: Accurate Voltage and Current Measurement

The AT35 USB tester is designed to accurately measure the voltage and current of a USB-A port. It supports a voltage range of 3.700-30.000V and a current range of 0-4.0000A, providing reliable data for various applications.

Clear Display and Wide Viewing Angle

Equipped with a 0.96-inch IPS LCD display, the AT35 offers a wide viewing angle of 160 degrees, ensuring that you can clearly read the data from various angles. This feature is particularly useful for users who need to check data without adjusting their position.

Advanced Charging Protocol Recognition

The AT35 can recognize multiple charging protocols including QC2.0, QC3.0, APPLE 2.4A/2.1A/1A/0.5A, Android DCP, and SAMSUNG. This capability allows for precise testing of different chargers and devices, ensuring compatibility and accuracy.

Power Bank Capacity Testing

Together with a USB electrical load, the AT35 can test the capacity of a power bank by discharging it from 100% energy to 0. Using the included formula, you can accurately calculate the power bank's capacity and determine its efficiency.

Charger Quality Assessment

To assess the quality of a charger, connect the same load to both the charger under test and a reference charger. Compare the no-load and with-load conditions. A greater voltage drop indicates a worse charger capacity and quality. Conversely, if the voltage does not drop noticeably or even increases, it indicates a better charger capacity and quality.

The AT35 is an essential tool for anyone who needs to test USB ports, power banks, and chargers, ensuring reliability and efficiency in all applications.
