Real-time detection of the state of charge of the appliance, voltage, current, power and other indicators at a glance; 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. 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

Review: Trabaja muy bien.
Review: This is a very nice USB tester which seems to be quite accurate. Large display that is easy to read. I like the various option available, like being able to rotate the display 180°, voltage, amps, watt hours, etc. I will probably end up ordering another.

## Features

- Guide Video: 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.

## Questions & Answers

**Q: What is the current consumption of the meter itself?**
A: The usb meter uses about 16mA and 7mA with display off.

**Q: What’s the difference between at34 and at35?**
A: At34 = 4 digits total (ex :  05.01v)
AT35 = 5 digits total (ex : 05.011v)

There’s no real guarantee the last digits are remotely accurate.  So get what’s cheap.  Use it.  When it burns out (like all cheap electronics) get another one.  Done

**Q: Does it allow data to pass while using it monitor power to a mobile phone?  Like plugged a mobile phone plugged into a pc?**
A: The current can be checked when the mobile phone is connected to the product while in use.

**Q: Can usb data pass through? (found my existing usb power meter doesn't.)**
A: Signal cables are straight through, you can use usb data.
