fast charge protocol identification, let you know the state of charge of the
phone . Power-off storage, data is guaranteed: AT34 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. USB 3.0 interface: Compatible
with USB 2.0, support high current test, support USB3.0 interface mobile hard
disk and U disk test. Package Including 1  AT34 USB Tester
 
Product Features
  

         
4-bit accuracy for more accurate measurements; Measure the load equivalent impedance and power; Thermometer function, Celsius and Fahrenheit free switching: Using high-precision thermistor sensor; USB 3.0 interface: Compatible with USB 2.0, support high current test, support USB3.0 interface mobile hard disk and U disk test.
         
The AT34 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. Fast charge recognition, widely compatible: AT34 supports QC2.0, QC3.0,for i Phone 2.4A/2.1A/1A/0.5A, for Andriod DCP, fast charge protocol identification, let you know the state of charge of the phone.
         
Power-off storage, data is guaranteed: AT34 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 (leisure loss) Compensation function) The better the load capacity of this charger, the better the quality.
