Review on Eversame 2-in-1 Type C USB Tester with Color Screen LCD - Ultimate Digital Multimeter for USB C Voltage, Current, and Power Testing by Johnny Chambers

Works well with my Pixel 4 and USB-C Power Delivery. At first I thought the USB-C ports had failed or weren't working. It turns out that a small micro-USB adapter (which would otherwise have nothing to do with USB-C) is absolutely necessary for this particular ammeter to measure USB-C power delivery. After I plugged it into the micro USB port in the corner case, the USB-C ports worked. A NOTICE. You may also need to power the USB-C device while the adapter is also connected to the micro-USB port in the corner housing. In my experience the display won't turn on when plugged into a USB-C PD charger when plugged in by itself e.g. B. when plugged into a regular USB Type A port.
