  It does a good job. It shows V/A/mAh all the charging parameters and how long it took. So I found out which cables were not good and which chargers didn't deliver as much as they claim.

  Correct measurements in volts and amperes, incorrect measurements in mAh. Not worth it if you want to make accurate measurements

  I'm not so sure about the accuracy of its measurements, but for the job I need it for and for its price, it's good.

  It is the most practical USB power meter-tester for simultaneous measurement of multiple outputs on a power bank or USB charger. There are two other models from UNI-T, each having only one output/input. The UT658DUAL has two inputs and USB extensions (type C and A), making it very convenient. It features two adjustment buttons and a large LCD screen with backlight that displays the measured voltage, power, capacity, equivalent circuit resistance, D+ and D- voltages. It can store up to 10 measurement groups. It is compatible with the PD 3.0 protocol as seen in the video with the measurements here: https://www.youtube.com/watch?v=gpMyVwkLgIs
  You will need a PD3.0 USB trigger to measure devices or PD cables.

  It does its job perfectly fine, I haven't seen anything negative.
