★The AT35 uses a 0.96-inch IPS high-definition color LCD display to display the state of charge of the appliance, voltage, current, capacity, energy, power, equivalent impedance, temperature and other indicators at a glance. 160 degree wide viewing angle, high brightness and long working life. Voltage: 3.7-30V; Current: 0-4A.Instruction link: https://drive.google.com/open?id=1XXUeqDZ4MZtmZGwSy0ld93bn_g2eoBi5.

★Fast charge recognition, widely compatible. Supports QC2.0, QC3.0, APPLE 2.4A/2.1A/1A/0.5A, Andriod DCP,SAM-SUNG charge protocol identification, let you know the state of charge of the phone.

★5-bit resolution for more accurate measurements. The screen can be turned off with one button and has a flip screen function. Thermometer function using high-precision thermistor sensor, celsius and fahrenheit free switching.

★AT35 has power-off storage function, which can store capacity and energy data when the mobile power is cut off, which is convenient for subsequent viewing and convenient for capacity energy measurement of mobile power.Note: Other USB testers that do not have a power-down storage function cannot test capacity and energy.

★Measure the quality of the charger: connect the same load, compare the no-load and the load, the greater the voltage drop, the worse the charger capacity is, the worse the quality; the voltage drop is not obvious or the voltage rises, the load capacity of the charger and the quality be better.
