Great USB tester!! It has a lot of functionalities (the ones described in the product description), the display is clear, the measurements are accurate, construction is solid with good materials. The trickier part is with the background lightning where you increase or decrease the time-out when you are at the BL screen: - press the button twice to increase the seconds and to also set the step to + - press the button 3 times to decrease the seconds and to also set the step to - After you've pressed the button 2 or 3 times and you've set the step direction (+/-) then you can hold the button to rapidly increase or decrease the seconds while you are on the same BL screen. This item is way better than the other cheaper USB testers that you can find on other stores or sites. I am so satisfied with the product that I've ordered another one! The shipment took about 3-4 weeks to arrive and it was tracked.

hello, for what has this USB tester got a spring?

LOL, it's not a spring. It's one of the electronic components.

Packing content:
1 x Digital USB Voltmeter Tester
Function characteristics:
1) 8192 pixels HD display;
2) D+ D-   Voltage Tester
3) Memory power time data such as power;
4) The single monitoring shows charging voltage, current, power, power WH,mAH, charging time and other information;
5) USB is the copper pin and a low resistance in sampling technology, access after almost does not affect the charging speed;
6) Wide voltage from 3.60 V to 32.5 V;
7) Low and lower power since the < 0.003 A (  <  3mA

8.When the power is > 0.5W, the time will be calculated!

Important Tips:

1)Backlit the default value is 10 seconds automatically shut down, if you need to close a backlight or normally open backlighting, please in double-click backlit screen button or click the button to adjust, thank you!


2)When the ambient temperature changes or the outside heat conduction to tester causes the current to not return to zero and the display shows 0.01A or 0.02A or otherwise,Please Hold on the key buttion then insert to USB Charger It can make the current temperature of the ambient current zero calibration,After the zero can more accurate measurements.And when in Zero calibration,the output can not have any load current consumption, so usb tester display 0.00A

    FAQ   ​

1. Why does the USB tester show 0.01A or other current when the load is not connected?

A: 1. This situation shows that the 0.01A temperature drift may be caused by the temperature drift current, make sure the USB tester is not connected to any load, and then press the button in the main interface 7 times, you can calibrate the current 0.00A!
2. Why does the USB tester show 0.01A or other current when connected to a load?
A: 1. Our USB test instrument using software calibration technology, in the case of no power, press and hold the USB tester's key, insert the USB charger, enter the USB tester background, shows 0.00A, long press the key , The screen appears "RESET" to restore the factory settings!
3. How to set the backlight?
A: The general factory settings, set the backlight is turned on is 10s Time, please click the button to switch to the BL: ON interface, press the button for three click consecutive strikes (-) or double-click (+) to set the backlight, there are three modes to choose from, you can set the BL : ON (backlight open), BL: OFF (backlight off), BL: 1S-59S (set the 1S-59S automatically turn off the backlight time)
