## Description

AT34 USB 3.0 Tester,USB Power Meter 30V 4A USB Voltage Tester Multimeter Digital Multimeter Current Tester Voltmeter Ammeter IPS Color Display Capacity Power USB Charger Tester

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works with low currents
*by G***G on May 9, 2022*

I am working on very low power IoT devices and I wanted an easy way to get a ball park measurement for how much power was being used without hooking up an oscilloscope or other equipment. I compared the measured power consumption against the o-scope and got 9.39ma versus the 9ma shown by this unit. It is close enough for me to use it as way to judge whether code changes improve the deep sleep current drain.This is a great tool if you want to quickly check current draw by a USB device.

### ⭐⭐⭐⭐⭐ Great device, needs a heat sink and larger enclosure.
*by D***N on July 14, 2024*

It definitely needs a heat sink and larger enclosure. Values are approximate as they aren't static.Charging a phone > 3.6 watts, 5.14v, 122mwh. LED light >1.9 watts, 5.19v 158mwh. No problems.The LED has a heat sink and runs hot to the touch. The tester shuts after about 5 seconds.

### ⭐⭐⭐⭐⭐ This is what you need to find the adapters that lie
*by S***R on January 21, 2021*

Glad i bought this. I found 2 adapter that was an out rite lie rated at 2 amp only doing 1 amp or less straight to the garbage they went.In short if you have an adapter that is taking a long time to charge something test it with this to see the output when the battery is dead many companies will over rate an item 2 amp you can expect 1.7 amp or better and watch the voltage sag if it less than 4.5 volts at full load toss it in the garbage. i had one rated at 2 amp and it was 3.97 volts @ 1.1 amp total garbage. The other barely 1 amp @ 4.9 volts garbage it went. Folks with todays tech stuff you need at least 2 amp and a stable voltage to get the phones and tablets charged in a timely manner and have enough reserve power to still use the devise.The battery in the devises is 4.2 volts and charging 5 volts in gets regulated at 4.2 if there is a bad voltage sag it takes even longer to charge. Im getting one 2.4 amp amazon basics adapter to see how it works to replace the 2 that i tossed out. If it does what its suppose to i may buy another one if not ill send it back but ill post a review on it as well.
