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.

Features

  • A simple little diagnostic tool.Functions well to monitor battery charging status. Shows volts supplied and amps drawn. Answered a few questions of your own as to why some devices charged better than others
  • Great little digital multimeter for testing voltage/amps output and power draw for usb-driven devices. Easy to read, helps identify which chargers put out the most charging current.This does do the trick for trouble shooting
  • This foolproof usb meter has been a real benefit in sorting phones, cables and wall warts adapters into how well they are working for each of these apple devices.Are they capable of supplying adequate power
  • A very handy USB power monitor to have around for checking both Vdc and the current a USB device would draw with re-charging and go to zero when fully charged
  • Unlike other USB multimeter, which displays voltage and current in alternate mode and you have to wait for the other mode. This device displays both voltage and current simultaneously!
