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

Clear and bright screen. Decent built quality. Great price for what you get. Lots of information in an easy to understand format. Fast and easy to use. Able to test a plethora of different cables. Fast delivery. Would buy from seller again.

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!

Now that we've settled on USB-C cables and they are used from computers to cheap toys, this is great for testing them and figuring out the specifications. You don't want inferior cables for your laptops, tablets, phones, etc. I use a label-maker to label my USB-C cables and some higher-quality USB-A cables. It's a bit OCD, but hopefully it matters in the long run. My only complaint is that it does not have an automatic shut off, so have AAA batteries handy. Of course, you can also power it with a USB-C, but it hinders the portability a little.

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

Works as advertised.

Es una excelente herramienta, tengo demasiados cables en casa y pues ya con éste equipo ya podré clasificar si es para datos de baja velocidad, alta velocidad o simplemente cable de carga.

One of the best purchases if you use lots of different Usb cables and devices. There are Soooo many reasons why certain cables don’t work. Usb is “less a standard” and “more a lottery” but this makes it simple to check and label every cable for it’s suited purpose.

Works very well. I am going through every USB cable in the house. If broken it gets recycled. Anything lower than USB 2 gets recycled. They all get labelled and marked if it can handle PD.

Device is easy to use. Helped me sort my usb cables by potential use and identify the capabilities of unmarked cables.
