MakerHawk USB 3.0 Tester, USB Power Meter, 3.7-30V 0-4A Voltage Tester Multimeter, USB Current Meter Tester, IPS Color Display Voltmeter Ammeter, USB Charger Tester AT34
Guide Video: https://www.youtube.com/watch?v=Alta7jcpgBI . Testers are widely used in the quality inspection of 3C digital peripheral products, and are the first choice for digital gamers and electronic enthusiasts.Real-time detection of the state of charge of the appliance, voltage, current, power and other indicators at a glance; Measuring voltage: 3.7V-30V; measuring current: 0-4A.
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: AT24 supports QC2.0, QC3.0, i Phone 2.4A/2.1A/1A/0.5A, 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.
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.
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.

Measure The Quality Of The Charger
Connect the same load, compare with no-load and on-load, if the voltage drops more, it shows that the worse the charging capacity of the charger is, the worse the quality is.
When the voltage drop smaller or voltage is increasing (charger has cable loss compensation function ), it shows that the better the charger's load capacity, the better the quality!
Quick Charge ldentification
AT34 supports the identification of QC2.0, QC3.0, apple2.4a/ 2.2a/ 1.1a /0.5a, Android DCP, and Samsung quick charging protocols, let you know your phone charging status.
Power off storage-Data stored
AT34 has the function of power off storage, When the power bank is power off, the capacity and energy data can be stored, which is convenient for subsequent inspection, and convenient for capacity and energy measurement of the power bank!
4 Bits Measurement Accuracy
At AT34 internal, adopt the professional instrument to sample circuit and use the Ruideng unique precision algorithm, which ensures the accuracy and stability of the product at the hardware and software level!
High Definition Display
The AT34 adopts a 0.96 inch IPS HD color LCD display with a 160-degree wide view, high brightness and long service life. Let you see from any angle to appreciate the color bright, exquisite and natural display picture.
Measure Load Equivalent Impedance And Power
Clearly understand the load impedance and current discharge power, better understand the load usage range, usage will be more convenient and faster.
