Simple device that does exactly what it says, shows voltage and current in a USB port.
I used it on a regular charger and a fast charger to check the charging of my mobile phone and Power Bank. Also on a laptop to check the operating current of a USB flash drive and hard drive. I cannot know its accuracy, but the values I saw at the beginning and end of the charging, as well as from device to device, were as expected.

The first 2 weeks were fine, then the problems started. At first, the screen brightness dropped, which I didn't really care about. Then the voltmeter screen went off and the ammeter constantly flickered. I don't know if it's the specific part's fault, but it's unacceptable for it to break in less than a month.

    Functional and very convenient. It's hard to trust metrics, but the deviation is very small, tested later with a multimeter. Recommended, especially for its price and the ease it provides.

    I use it for mobile repairs and it has been working perfectly for a year now. It supports fast charging at least up to 9.2 volts, I don't know about higher. It is definitely worth the price.

    It works as promised. It seems to not work with currents below 0.1A, but considering its price, it's fine.
