I just got a UM25C, and it works very well when powered from a 5-volt source: male USB-A plug; micro USB port; USB-A to USB-C cable plugged into the USB-C port. But, when I use a USB-C to USB-C cable to plug it directly into a USB-C power supply at 20V, it does not turn on. How do I make that work?
Hi friend thank you for your message. because our UM25C don't support PD trigger, when you connect PD charger, don't connect PD load, our meter will not light . so you need to connect a load supporting PD
