Richard Mundy: I keep it ready for all-around use with the varying devices I use. It's one of the most used products to check USB cables and input and output voltages of these small devices.

Michael: Was testing my mobile phone power draw had to take it out of its case which was a minor issue the it worked perhaps a little longer connections

n-squaredn-squared: This device is a great way to test various charhing combinations of chargers + cables to isolate if a cable is the problem.
It also helps me understand the real charging characteristics of the device being charged.

I'm knocking off 1 star because it looks a little delicate (but it is offered at a VERY low price point) and there's a kludge micro-usb adapter add-on, and the device needs to be treated delicately.

Very many software modes and not too much instructions, but with a little bit of trial and error, I figured out how to get the readings I needed (see my attached pic).

Can also be used for longer time monitoring of the device.

TomTom: Exactly what I needed: a low-priced way to test chargers and cables to see if they support USB-PD. In this, it rates 5 stars.

I didn't need--and am not evaluating--a rugged device for the everyday use of a design engineer. I didn't need--and am not evaluating--a precise and well-calibrated meter to design, test, and/or operate mission-critical equipment. I didn't need--and didn't test--its more advanced features (e.g., amp-hours). I used it only to look at Amps and Volts in real time--which is the best way to test chargers and/or cables.

And for that--testing chargers and/or cables--this is an awesome little gizmo at a great price!

The problem it solves: there's no good way to quickly tell how fast an iPhone is charging without an external meter. There are a few apps that claim to do this, but all they do is watch battery percentage and do a little math. Which is both slow and unreliable.

And--like other reviewers have noted--most USB-C-to-lightning cables don't support fast charging, even if they claim to. Want to know for sure? Use this meter.

To test cables and/or chargers to see if they will support fast charging: watch the meter voltage....
