Treedix USB Cable Tester with 2.4" Color Screen for eMarker Reading, PD 3.0/3.1 Detection, Resistor and Continuity Check, Compatible with Lightning, Type-C, Micro-B 2.0/3.0, and Mini-B Cables

Cables, Cables, Cables! Cables have gotten a lot more sophisticated over the years. It’s no longer just wires connecting two ends. Many modern cables include internal circuitry, chips, and e-markers that tell your devices what they can handle in terms of charging and data transfer. This little tester removes the uncertainty of trusting cable descriptions. It works with USB-C, Micro-B, and Mini-B cables, and can check continuity, data capability, and resistance. It also reads USB-C e-markers to show power delivery and data transfer capabilities, which is very helpful when sorting through a drawer full of mixed cables. What I like: - Works with more than just USB-C cables, including Micro-B and Mini-B - Reads USB-C e-markers to identify supported charging and data specs - Checks for continuity and resistance to verify cable integrity - Compact, easy to power with either USB or AAA batteries - The color screen is bright and clear, with an intuitive menu system It doesn’t test real-time charging performance, and that’s fine since that’s not what it’s designed for. I use another simple tester for that. This one is for verifying specs and quality, and it does that job perfectly (see pictures). If you have lots of cables and want to know exactly which ones are high-quality or support fast charging, this is an excellent tool to have on your bench or desk.

This is a very simple product to use to test a variety of cables. Very easy to read and provides quick, accurate information. Although a small item, very solid built product. Don't know about $45.99 that I spent (as I found that to be a bit high for a price tag), BUT, I couldn't find anything to compare it to. But it very functional and works great!

Great little device. Being in IT, I'm always figuring out what cables are bad or good. This device will not only tell you, it will let you know if cable can carry data as well. This is super helpful if you're trying to connect your Apple Car Play / Android Auto or your phone or device to a PC. I like the color display, it's easy to read. The features I like are the multiple types of USB you can test. Overall, I never thought I needed it until I got one!!

So far, it has been working just fine for me. I like how easy it is to use. Another pro is it comes with an actual, well written, physical manual, not a QR code I have to read to download a manual. It uses a single, replaceable AAA battery to power it although an external power supply can also be used (I prefer battery operation over having a restrictive "umbilical cord" to a power supply. it ships in a well protected, reusable cardboard box. The one i received was obviously an open box (not sealed in plastic wrap like ones in review videos I've seen) but was probably unused since the included battery was still in its factory plastic seal. The box looked like it had been stomped on (thank you, Amazon, for shipping it in a flimsy envelope) but the tester itself looked just fine. Thanks to the plastic insert the tester was nestled into, the box is still in good enough shape to safely store the tester and its manual. I have four cons, though. The cover over the battery compartment was so tight it needed three men and a boy (which I didn't have handy) or a knife (which I did have handy) to get it opened (possibly the reason it had been returned). The included AAA battery was garbage. It provided power for my initial testing for around 30 minutes, then, after sitting in a drawer for a week, it was dead (yes, the tester was turned off and even if it wasn't, it turns itself off long before it can discharge a battery, another pro). I didn't take off stars in the rating for this because I have a herd of rechargeable AA and AAA batteries and had planned on using those once the original battery died. The third con is the location of the USB ports on the tester's case. The Type A and Type C output ports (actually, I would call them input ports) are located on one short side of the case and the input ports (I would call them output ports since some are Type B) are on the bottom of the case. That makes it impossible to test short cables. For example, I have a 4 inch USB 4.0 cable. it is impossible to test on this tester. I haven't checked to see what the minimum length of a cable that can be tested with this tester is but I would say it would be 6-8 inches, depending on the length of the connectors on the cable. If all the USB ports had been located on one side, it would have been possible to test shorter cables. Even though it would cause the case of the tester to be longer, it would have been worth it. The last con (and the least significant one) is not all USB connector types can be tested on this. On the "input" side, there are ports for USB Type C, micro B, and mini B (there is also a Lightning port). USB 2.0 and USB 3.2 Gen 1 Type A and B ports are missing. I have a lot of USB 3.2 Gen 1 Type A to Type A cables so it would be nice to at least check them for continuity when there is a problem or when sorting them out. Fortunately, I have only two devices that use USB 2.0 Type A to Type B cables—a flatbed scanner and my UPS— and only one USB 3.2 Gen 1 Type A to Type B—a duplexing ADF scanner. It would have been handy to have had a tester to test the latter cable when I had an issue with the scanner dropping out instead of having to order another cable and wait for it to be delivered to see if the cable was the problem (it was).

This is a handy little tester that helps you determine the properties of a cable, which often aren't obvious just by looking at the cable. It's very easy to use and although the display is fairly small, it is easy to read because the information is presented in an organized fashion. This tester supports cables with USB A or USSB C on one end, and either USB C, Micro USB, Mini USB, or Micro USB "3.0". Unfortunately it does not support USB B ("printer style") connections or USB B 3.0 style cables. Since those connectors are larger, I believe it would require the tester to be thicker. Additionally, this tester does not support lightning cables. There are 4 "screens" of information which you cycle through by pressing a (very) small button. The first screen is an overshowing if the cable can transmit data and power, and which type(s). The second screen shows the actual wire connections and their status. The third screen shows the cable resistance and can estimate the cable length, and the 4th screen will show the details of an active chip if there is one in the cable. Every computer technician or enthusiast should have one of these in their bag! PROS: * Small and easy to use * Gives you all of the details you need to know about a cable * Flexible and supports a number of common cable types and configurations CONS: * Does not support USB B, USB B 3.0, or lightning * Button to move between screens is a bit small

This does exactly what I need. I can plug in the usual types of USB cables, and it will tell you the functionality of each one. As an example, you'll probably be surprised to find out which USB C cables can pass data, which ones don't, which ones have full functionality, and which ones are only good for a charge. It gives me much more information than I think I'll ever need, and it's easy to use. Great for cable testing and finding out if you have a problem cable or not.

Works great and was able to test every cable I use. I found several that were not capable of fast charging, fast data speeds, and some that were not working right. Amazing. The hardest part of using it was trying to remove the battery cover so I could remove the plastic insulator - it was really difficult and I had to use a tool to force it off. Recommended product!

This was kind of an interesting find. I was looking for a way to determine which USB cables did not have a data transfer function (or charge only). This allows for a full analysis of the various cable wiring. This is a packaging and funtion upgrade from the Treedix PCB analyzer.
