As the upgraded version of USB PD3.0 protocol, the new USB PD3.1 protocol can support up to 48V, And the charging power can reach 240W. According to the documents from USB-IF, the USB PD3.1 can support extended power range (EPR) of 28V, 36V, 48V and three sets of adjustable voltage supply (AVS).

It fails to find a USB-C cable every time, and says there are no fast charging protocols in my fast chargers with known protocols. I've tried reading the documentation, multiple cables, chargers, and configurations. I've double checked against review images that have working results. I'm using it correctly, it just doesn't work.

Normally done to test power bank but can also test specification of a usb-c cable by connecting one side only on the right.

This is probably the most complete and advanced usb tester available. It works great and has more features than I can use, but it should for the price. It's certainly the most expensive one around.

Das Gerät ist für das Gebotene recht teuer, aber gut verarbeitet.Und es bekommt regelmässig Firmware-Updates, meines kam mit V 1.9.4, die Tage gab's schon die V 1.9.5.Es wird immer besser...

This little meter works well and has a bunch of handy features for exploring USB PD and other charging protocols.

Alot of love has been put into this design and the software that goes with it.The software has a USB-C PD protocol analyzer that shows you the communication between devices as they negotiate the voltage and current levels that will be allowed and supplied which is very helpful if your designing a device that had USB-PD sink or source features which is what I'm doing which is something I have not seen in a device at this price range. This was a pleasant surprise when I started looking into the software features.The firmware is easily updatable via the software also which means you will not be missing out on any new features as the USB protocol changes over time.The display has a very nice layout and is easy to read and and navigation of the features is alright once you get used to what buttons do what.It's surprisingly smaller than I expected which makes it easy to bring along if you want.For me this allows me to quickly verify the power output of battery banks, AC chargers, and the power consumption of devices I use or am testing. The software allows you to graph out everything over time and save it to a file for later use or comparison.I can tell a lot of love was put into this design, UI, and Software and feel like for $100 it's a steal if you can use all the extra features it provides.Chargerlab has a great Blog where they tear down power banks and bigger solar charger systems and show exactly what is inside and what chips were used if your into those types of things. They use this meter to verify the capabilities of all these different products which means they have to make sure the meter is capable of detecting all the latest USB PD and other standards which means this will always be getting updates as things change over time.I would say spend the extra money and buy this one if you want the best.

ChargerLab KM003C is by far the most modern USB-C tester, preserving all cable lines, thus it is Alt DisplayPort compatible and allows for video signal transmission with PD 3.1 support. It is surprisingly small, and the screen displays more information than the competition. By far the best USB tester, kudos to ChargerLab.I am providing an overall comment for three USB testers, all of which deserve to be purchased as they complement each other perfectly and are consistent in their results.I would like to dedicate the majority of this review to the Bit Trade One model, which has recently arrived on Amazon. It deserves a shoutout because the tool is exceptional and inexpensive for what it offers.The ADUSBCIM is a USB cable tester that truly complements traditional USB cable testers. Only the cable to be tested needs to be plugged into the A and B ports, and the tool does the rest.The reference value for calculating the cable's resistance is taken using a CR2032 battery, and I note that the calculation is very precise and stable.You can find on Bit Trade One's ADUSBCIM GitHub page, in the Pull Request section, a manual in English in PDF format. This is my small contribution to the project, as the current official English manual is more of a word-by-word description that is difficult to understand.Thanks to this tester, I discovered, for example, that Anker cables, the 765 series, were actually poor high-resistance cables, and that I had much better options for charging. I ended up wasting money on cables that turned out to be slower than cables that were given to me for free with computer accessories.The FNIRSI FNB58 is a very comprehensive USB-A and USB-C port tester. It notably offers numerous rapid charging protocol tests, can test the quality and resistance of a cable, and obtain oscilloscope-like graphical representations. Now that we are on PD3.0 and with PD3.1 approaching quickly, owning one of these tools is now essential to validate the proper functioning of an installation.I've read a lot of advice on Reddit, and if you're looking to equip yourself with the best products offering the most testing possibilities, here are the tester references to get:- Bit Trade One ADUSBCIM (very thorough cable tester testing all the lines of a cable)- FNIRSI FNB58 (the most comprehensive, many ports, many scenarios, USBA/C Micro)- ChargerLab KM003C (the most modern, TB4, 250W)If you have these three or at least a combination of the cable and usb tester, it will take you no more than a few days to become a USB expert. 👌

Took me a minute to figure it out and even then I'm still not super sure as the provided instructions and online PDF can be a bit tricky.If somebody were using one without prior experience or knowledge they'd have a tough time confirming what they wanted.

I could not figure out why some of my devices were not charging as fast as they 'should'. I used this wonderful device to troubleshoot, and found that some of my cables were not great.This device is *fantastic* for troubleshooting and verifying you are getting what you think you are.For example I learned our car is only spitting out 7 watts from its onboard USB ports. My anker powerbank is a 140W unit, but I can only get 30W to my portable device. That's when I learned my portable gaming device has a charge limit of 30W - good to know, now I can plan for how long it will take to recharge under the best of circumstances.So much good use for this tool, I highly recommend! It comes in a nice metal tin case with a protective foam cutout surround to protect it.

Es una herramienta de diagnostico bastante util, si te interesa conocer la capacidad de carga de tus dispositivos, bancos de energia y los protocolos de carga de los distintos tipos de cargadores, ademas de verificar la veracidad de alguno cargadores, en especial los de Apple. Es un poco elevado el costo, pero si eres técnico o un fanatico de la tecnologia, es una buena herramienta.

Das gerät hilft zu erkennen ob ein gewisser Standard vorhanden ist und ob eine Sicherer ladezustand möglich ist.Mit der Software kann man einen Kompletten Ladezyklus oder Entladezyklus überwachen und dadurch auch den zustand des akkus erfassen.von daher von mir 5 Sterne, alleine schon dafür das es mir die Möglichkeit gibt Sicherheit statt "Brand" zu erreichen.Mistet eure kabel aus und macht QC/PD draus und setzt auf e-marker chips in kabeln*Nicht jedes Teure -Emarker-Kabel ist auch gut" Schaut euch tests und rezessionen an die helfen auch weiter.

this products really is the best in class, however the PC software is largely in Chinese, and many of the abbreviations on the multimeter unit as well as PC software are never explained, there is a big learning curve to using this. still rating 5 stars however.(this review does not factor in price, which is very expensive vs competition)
