Review on ⚡ YOTINO USB Voltage/Amps Power Meter, Tester Multimeter for Assessing Charger, Cable, PC, Power Bank Performance by Preston Molden

The counter didn't work. I plugged it into the charger and then into the laptop I was testing and got no readings. Tested on a work laptop. I couldn't get any readings and my laptop wouldn't charge. I pulled it out and plugged in the charger as usual and my laptop charged. I tried using my phone which draws around 1A and it worked. It may not be able to handle higher currents. I bought it because I saw a YouTube video where a guy was testing the same laptop I was repairing with the same issue I was having, so I figured it must have worked. Spring. I don't need any more, but I might order another one in the future.
