This thing is so cool, even if it isn't perfect
This meter, when it works, is so cool and has a great modern screen with high resolution and crisp clear text/numbers. However, sometimes it doesn't register amps and therefore watts are not calculated either. This happened when I used a PD 30W and also a PD 65W charger with a USB-C cable plugged into an amazon basics wireless charger (claimed 15W). The display shows 19.xx volts but no amps being pulled.Other times if you have the USB-C cable plugged in it won't show anything but if you turn, note the universal direction cable, around it will then register and the display will show up. literally turn the cable upside down and it starts working?!?Another gotcha is that you must have the input and output correct otherwise it won't power. Note that sometimes, haven't figured out why, but if you have the power source plugged into the output (it's hard to read what is in and out) then it will power up and then you plug in the destination the display goes away; thus indicating you were wrong in how you plugged it in.But I will say that mostly this works and works very well plus has really neat advanced features like graphing of Volts and Amps over time in a scrolling line graph. Lots of info for view and peruse.Overall this is solid and I give it the full 5 stars, even if it is a bit flaky and not perfect and doesn't work all the time, I chalk that up to the varied charging circuits and the only somewhat regulated and standardized industry.

An Excellent Multi Purpose Multimeter
With the included USB C cable and a couple more cables that I have laying around, this meter helps me weed through the power blocks I have to figure out which I should use to charge my multiple devices. Without cutting up a bunch of USB cables and sticking a Fluke multimeter in line, I can't speak to the accuracy of this meter. But it does allow me to see the voltage, amps, and watts of various power blocks, which is all I really care about (yes, I could calculate the watts from voltage and amps, but why bother; this thing provides the value for you, and for about $20, what a steal).The one problem I had turned out to be user error. When I got this thing, I was so eager to try it out that I just plugged it in without reading the instructions. Which worked great, except that the meter kept turning off after about a minute. After reading the instructions, I adjusted the "Delay off screen time" setting to zero, which keeps the screen from going to sleep. (Yes, honey, I know - read the instructions.)

Great tester, rocky experience. Eversame made it right.
Originally I thought I was purchasing the meter, the cable, and the load tester, as they were all pictured in the listing without clarification that the load tester was not included. After expressing my thoughts in a review, I was contacted by the seller. I explained the issue, and they immediately updated the listing photos to clarify the load tester isn't included and offered to meet me halfway on the cost of the load tester. So it worked out in the end, and the listing was updated so others don't make the same mistake, so I can't really complain now.On the plus side it's a very accurate meter. It's not exactly the most finished, since it's just a board sandwich with exposed components, but it's one of the better functioning meters I've used. It's surprisingly within 2% of my Fluke meter, at least when it comes to voltage and current measurements. I didn't compare the resistance readings since it's not easy without opening the source charger itself, but based on the voltage and current measurements, I'd wager that the resistance is close to the same tolerance too.Very good product backed up by great support!

Very good measurements, some functions are hard to read
The meter does its job of measuring voltages and currents accurately. This is the best tool to determine USB cable quality as it can detect the resistive levels in each attached cable. I was charging a tablet with a Micro USB cable and the meter indicated a low 0.2 A current flow. Replacing the cable allowed the tablet to charge at 0.7 A and the meter indicated a current drop to 0.1 A when the tablet was fully charged. It works only with USB type A, Micro USB type B, and USB type C cable connectors. No Mini USB or Lightning.

Works very well
This is a very cool device. Not only can you test your USB charger's voltage and current output but also a very little known operation that you can perform is to check if you are using a spy cable. There are some malicious USB cables out there, I've attached a picture of one. To test for a spy cable, connect your tester to a USB charger then connect the cable to the tester but DO NOT connect the other end of the cable to any device. If your tester is showing that the cable is drawing current, eg: 0.200mA or so, then be suspicious of that cable. A valid type "A" USB uses 2 of the 4 wires only to charge your device and does not use the other 2 data wires. If it draws current then there is an electronic device molded into the USB cable connector.

Minimally useful - most features don't work
This is either junk or defective1) It does not support USB-C PD (Power Delivery) at ALL. The device will not even power on when connected to a PD charger, even after flipping and rotating the usb-c cable every possible way.2) The fact that the devices requires the USB-c cable to be oriented 1 way is a design defect - usb-c was created to eliminate the need for flipping cables around. Might as well use micro-usb since at least it only goes in 1 way.3) I could only get it working through USB-A connections, and then it would only support up to QC2.0 - 11-12 watts. I couldn't get it to support QC3.0 nor would it work on my my super fast chargers which do 5v 4.5amp, it only provided 12watts max.Returned for a better product that actually works.
