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.
