USB C Power Meter USB C Tester, USB Multimeter 4.5-50V 0-12A Two-Way Measurement Voltage Current Capacity Amp Volt Voltmeter Ammeter Detector Color Display Digital Tester for Chargers Power Bank Cable

Very nifty little device. Works right out of the box and provides USB power information that wasn't available to me previously.

Works good so far! Will provide updates IF it stops working and/or malfunctions in any way.

This device is great for finding out which chargers and cables charge your devices the fastest. I was able to find out what charger and cable combination charged my Fire tablet at 15W.

This has worked great for my needs. Pros: Easy to read LCD Simple interface Screen rotates 90, 180, 270, 360 degrees LCD has a good refresh rate Value Voltage Amperage and Wattage all seem reasonably accurate. Cons: I am not sure the Watt Hour (Wh) measurement is very accurate. I used a 5Ah M18 battery with a PD100 watt adapter to charge my laptop and when the battery was depleted to where it shut off it was reading 122Wh from a 90Wh battery. This was not just one battery I had 4 M18 batteries, so either they are all under rated or this meter does not have enough resolution to accurately measure Watt Hour.

Can’t really tell how accurate the measurements are but certainly good enough for what I need. Easy to use with all of the modes.
