Review on 🔌 DROK USB 3.0 Hub Multi Tester with OLED Screen: Pocket Digital Multimeter, DC Voltmeter Ammeter, Capacitance Meter, Thermometer, Energy & Time Battery Monitor, OTG Connector Output with Auto Off by John Sharma

This USB power meter supports additional USB 3.0 pins, which is an upgrade from my previous USB power meter. I also like its shape, my previous USB power meter had a strange shape that sometimes disturbed its use. It is convenient when all measurements are displayed on the screen at the same time. The button on the back is covered with a sticker and is not immediately noticeable. I was testing the current draw of a USB powered microcontroller when this power meter turned it off. "UCP/OFF" appeared on the screen. I had to read the instructions to figure out how to disable "undercurrent protection" (double click to change configuration). After doing that, everything worked as I expected.
