USB Power Meter Tester Digital Multimeter Current Tester Voltage Detector Lua interpreter integrated DC 26V 6A PD 2.0/3.0 QC 2.0/3.0/4.0 pps Trigge (CT2(Meter only))

Great for testing out: + different charging cables to see if they can actually support 2 amps. + different charging devices to see if they work as advertised. + 18650 batteries storage capacity (discharge them through a phone charger that has removable battery option).- All of the controls are not obvious so read the instructions. It’s controlled entirely from a tilt wheel that you can also depress. There’s 4 different control inputs.1. Tilt forward2. Tilt backwards3. Long press4. Double click.If you get into menu options and want to get out, it’s a double click, this can lead to accidental menu selection if you’re not fast enough. I think they should switch the “backwards” control to a long press backwards on the tilt wheel. This would stop the accidental selection problem. It seems they could do this by just updating the microcontroller code that they have written for this handy gadget.- Also, I bought a different one of these that was similar but allowed me to rotate the screen 90 degrees any direction by pressing one of four buttons it had at each corner.This one also has the option to rotate 90, but it’s from a “long-hold tilt forward” on the control wheel. I didn’t know this for a while.All the control is condensed down into a single tilt-wheel, so be sure to read the instructions.

For starters, this is clearly consumer grade (and on the toy end of that). While the meter is generally accurate its measurements are rather noisy compared to the readings of a metered test load.The device and software work well. However, the documentation and help guides are disorganized and hard to follow. This is concerning given the nature of testers like this and the possibility of frying valuable electronics. It will always require a good understanding of USB charging protocols and the devices function to use safely, but this is more difficult to do with the resources availiable for the CT-2.

I bought this Power meter primarily because it had a sample rate of 100 Samples/s and could record to a computer so I wouldn't need to worry about memory.Turns out, this 100 S/s can only be displayed on the screen of the device which is totally useless, the data just scrolls off of the screen in one second and you can't capture anything to analyse the patterns. The Windows app is limited to recording things at 1 Sample/s despite getting data from the device at a higher rate (judging by how often the Voltage gets refreshed on the VS how often the curve update). Oh and to top it all it's buggy, the app keep stopping the recording with no reason and the I had issues with firmware update that wasted over 2 hours. If you have issues, try restarting your computer after the driver install step.Anyway, this device is made to look cool, not to be a useful tool for power monitoring and measuring. Finally, the software is not Opensource so I'm not very trusting on what it does. It also means that I can't just write my own app to collect data from the device since there is no "SDK".If you want a basic reading (what this is really giving you) just spend ~$20 for a cheaper device that will do what you need. This is not worth the extra money.

The interface is not very intuitive and hard to navigate. Works well but I believe there are better alternatives.

Works great for testing everything usb. It will even allow you to put power in via USB-a and output by usb-c. I haven't found a combination it doesn't work on. It also has usb-pd trigger built in so you don't need a separate module for higher voltages during testing.

May have some incorrect work or even not start with USB-C, but works for me.

This analyzer is an awesome tool for anyone trying to work with USB C. It does power monitoring with a full range from ~3.7V up to over 20V. I've used it while attached to a computer to decode Power Delivery packets and as a test unit to verify a new devices baseline Power Delivery compliance. It supports fixed profiles and augmented programmable power supply profiles in PD. Also it has a list of other supported profiles to include: QC2, QC3, Auto Enumerate, Apple 2.4A, Apple MFI Test, Power Delivery 3.0, HUAWEI FCP, SCP, and SSCP, Samsung AFC, VOOC, Super VOOC, and E-Mark reading.In general, I've used this a ton for software development on new Power Delivery devices and it works great to allow for sanity checks and development. The interface can be a little frustrating at times with double clicks to go back and restarting the device between using different types of fast charge interfaces.
