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 thing can help you go through your heap of USB cables and separate the good ones from not so good ones. Easy to use.

Like most people I have a pile of USB-C cables - and by this I mean cables that have a USB-C connector on one end and more or less any connector on the other end. But there's no way to tell by looking at the cable what the maximum data rate is that it can support or how much power (watts) it can transmit. Sadly, the USB committee never came up with some sort of labeling standard that would allow one to determine what a cable was capable of. As time moves forward more things are using USB-C as the power supply connector which is a good thing. The bad thing is that some of them require more than the 5 volt, 3 amp capability supposedly supported by every cable. Try charging your computer with a generic gas station cable and see how that works. This was the best solution I could find which gives a clear and quick analysis of what you have. Supports lots of different kinds of connectors. Easy to understand the display. There are more expensive solutions on Amazon so this is the best value I could find. There are also cheaper ones that are hard to use which are just a bunch of LEDs without much in the way of telling what they mean. And those don't read the e-marker chip so they are much less useful. I also like the face that it tells the resistance of the cable. All other things being equal, a lower resistance is always better for a charging situation. I do wish that the little selector button the side was slightly larger. It's functional but kind of tiny.

It's a good way to know which cables to throw away, either because they have bad wires or are just old. Three criticisms. 1. It's a bit pricey. 2. It goes through AAA batteries quickly (at least the rechargeables). 3. It didn't come with the USB Cable Manual that Treedix has for its more 'primitive' USB Cable Tester. On the plus side, the E-marker chip and the information that comes with it are excellent.

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!

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!!

Well, in my opinion it is. Does just what it says it does, and has performed great for me so far. I have well over a hundred cables that are either microUSB 2.0 to USB-A, USB-C to USB-A, or USB-C to USB-C, and this USB cable tester is great for separating the good ones from the not so good ones. Just as it has done for the cable that I have shown in my pictures. Well, there's not much else I can say about this cable tester that hasn't already been said. Except maybe, just keep in mind that this device is only meant to test cables themselves, not any devices or what the charge rate is of a device. Treedix DOES have other devices that can test charging rate and whatnot though. But anyhow, I would definitely recommend THIS cable tester to anyone who is considering getting it.

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

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.

Item is as described. Fast delivery. It is a bit expensive but display the necessary info about the cables. I wished the device can update future firmware when technology evolved. Thank you very much.

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.
