## Description

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

Review: Works as expected, the flexible cable is a life saver! - 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.
Review: Great little device - 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.

## Features
