Works good and has a nice bright, albeit small display that you may need a magnifying glass to see but there is only so much tech that you can cram into a small form factor device.

I bought this to test different USB cables that I could use with either of our 2 phones. Turns out that some of the cables did not provide nearly as much of A charge as some other cables do. So this helped me weed out cables that do load charges as opposed to the cables that charge much faster.

meh. i had to download a pdf in Chinese, drop it into google translate to identify what the capabilities are. I came this close to returning it, simply due to lack of docs. If there is an App, it isn't clear where to DL that app. really not needed, but I find that i wasted some time just to read the docs.I'd give a better review, if it weren't for the POOR doc.

It works as advertised. The display is small which was expected.My first complaint is that the amperage display (most important to me) is blue on black which I find hard to read. The second is that you must download an app to read the english instructions. Of course I refuse to install a pontentially dangerous app. I figured out how to use it from the images above.

For the price it's a great little tool for seeing how many volts and amps is being yanked out of your plug to power your phone or tablet or whatever.

The product works great. The Voltage and Ampere values are displayed prominently in the screen. the other values are small and hard to read for a person with low vision.The temperature is not displayed correctly. It displays the circuit board temperature instead of the room temperature.
