USB Power Meter, Eversame 2 in 1 USB C Power Meter Testers LCD Digital Multimeter, USB C Voltage Current Voltmeter Amp Volt Ammeter Detector USB Cable Charger Indicator DC3.6-30V/0-5.1A (2-Pack)

I use this for making sure my usb c and usb a cables are supplying enough current.The meters seem to be accurate.sometimes it takes a minute or so to show the expected result.Not sure if it is the meter or the device ramping up

Screen has small text ... I need reading glasses anyway so must use extension cables to be able to read. Tested to see how much charge it took to charge some cell phones. I like the USB 3 ports.

USB C only works in one direction. Display is small and hard to read.

Works great
