L'ho comprato per tenere sotto controllo la batteria di un pannello fotovoltaico e capire all'incirca la carica residua dopo le ricariche dei vari dispositivi.

I got this usb power tester to see how much charge I was getting from my 20W solar panel into my powerbanks. I have a 5V buck converter connected to the output of the panel, followed by this device, then the usb cable for the powerbank. It gives me all the info I require: Volts, amps, time, and power output. It has a reset button which you hold for a couple of seconds to reset the device.I have also tried it on a couple of my chargers to check their output levels and works perfectly.I'm very happy with this cheap little device and would recommend it.

It works well, so show the power being drawn on various devices, including my solar panel.

This is great for quickly measuring USB voltage and current draw. However, I regret not thinking about the inputs I would need. I had some Micro USB chargers, which I could not test without an adapter. Also I expect I will end up with USB-C devices I want to test in future. Other USB power testers available would have given me greater flexibility.
