About this item
- NEW Arrival USB Tester: Upgraded color USB tester feature a 12,800 pixel IPS HD colour digital LCD screen for clear readings; screen rotation function allows readings to be taking in different directions. Meanwhile, to ensure more accurate measurements, USB meter tester uses a sampling chip with an internal resistance as low as 1 milliiohm (1mΩ), reducing self-consumption while providing you with more reliable values. d car charges more easily.
- Multi-functional USB meter. USB meter tester is mainly used to detect USB charging current, voltage, capacity, power, time, etc, displaying accurate data for you in real time; detecting the quality of charger and cables, providing a safe charging environment for your valuable devices. USB tester can automatically detect different fast charging protocols, including APPLE 2.4A/2.1A/1A/0.5A; Android DCP/AFC; HUAWEI FCP 9V/2A, SCP 4.5V/5A; Samsung Qualcomm QC2.0/3.0.
- Power-off Memory Function: Testing the capacity of a power bank requires completing discharge process from 100% to 0, which will take a considerable amount of time to complete it. Power failure storage feature allows you to finish this process in one or more passes, as it will accumulate capacity again when power on again. Up to 9 sets of data help you easily calculate the real capacity. Screen can be shut off during this process or at night for distraction-free experience.
- Wide Test Range & Simple Operation: Input/Output Voltage: DC3.6-30V, Current Range: 0-5.1A. Large range of USB meter makes it widely compatible with USB-A port devices such as mobile phones, tablets, laptops, car chargers, power banks, wall chargers, cables, etc., displaying charging data to you in real time. USB tester is compact and portable, providing a safe environment for charging every time, wherever you go.

There was a problem filtering reviews right now. Please try again later.
However, there is one aspect where it falls short, data passthrough. Not being able to monitor the voltage and amperage while USB devices are in use can be somewhat limiting if want to keep track of fluctuations during use. Nonetheless, considering its affordability and ease of use, this USB Voltmeter remains a fantastic addition to my toolkit.
However, you could remove the "-USB Tester-" line ( I think we know what we ordered ) and use the space to make the smaller fonts a little larger and easier to read. Also, the red and dark blue colors are difficult to see, especially in well-lighted offices. - ECE Tech
Using the device can be a pain, because the display goes off after a few seconds, and when you push the button to bring it back, it goes to the next screen, and there are at least ten screens (some for readouts, some for settings) that you have to navigate through to get back to the opening screen.
If you unplug it, then plug it back in, it seems to go back to the starting screen. The minimal sheet of instructions seemed to indicate there are fewer screens, plus hitting the single button is supposed to bring you back to where you were when it blinked off. Not with my device. In any case, my use is minimal and it seems to give me Volts and Amps as needed. BTW, a couple of duplicate screens are in -- I am assuming -- either Chinese or Korean. Maybe I received a Beta test version.
I will say that I ordered two similar devices at the same time for my testing purposes and ended up using the other one because after spending almost 10 hours with this one to test the capacity of a power bank, it did not save the value at the end of the test, requiring me to recharge the PB and start all over. The other device did work successfully, and I have been using that one mainly.
I admit I probably did something wrong, and I have not examined all the function of this unit, but that bit of aggravation with the PB test kind of put me off.
