YOJOCK USB C Tester Power Meter 4-30V 0-6.5A Digital Multimeter, Type C Voltage and Current Tester Meter, Power Capacity, Working Time Ammeter Voltmeter USB Cable Charger Detector (Classic Version)

I bought this to replace another meter that worked great except it had a fixed USB-C tip. Accuracy was great and it was very easy to use, but it is inconvenient to attach to devices and its tip broke off within a week. This one is identical except it has a shot flexible USB-C cable instead. And that makes it just perfect! it is now easy to attach it laptops, phones, and other devices, and it is safely attached and I do feel it has no reason to break off. The meter works beautifully, showing accurate and realtime data regarding the power flowing though it. it also calculates the power drawn over a specific time period (click and hold the switch to reset and start a new session), and it is remembered even if you unplug the meter.

I use this for testing power with microcontrollers and while I cant speak to exactly how accurate it is, it does seem to be accurate enough for my use cases. I like that it shows mA/A, mV/V, mWh, mAh, and run time with a simple button to reset the timer. Really useful for getting power draw and battery run time estimates. It even shows the direction the current is going with little arrows.

Semble bien fonctionner et reste opérationnel avec le temps je recommande !

Very interesting to see what's really happening over that USB-C charging cable (e.g., devices switching between 5/9/12 V during one charging session). I picked this product because of the attached cable: more convenient than a male plug end that some competing products have. I will be testing the capacity of my powerbanks; the device tracks total Wh that passed through it, even with interruptions.
