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

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.

Excellent USB lead tester for routing out those poor quality usb leads you may have with details of power or data or both.

Tenia muchisimos cables y ahora tire mas de la mitad porque al fin pude separar los que valian la pena de los que no servian para nada. Perfecto para conocer y auditar tus cables incluso validar que los nuevos sean como los anuncian o si es una mentira. Te va ahorrar molestias si la transferencia de datos es algo importante para ti y no saber que cable usar

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.

I like that this tester lets me know in less that a minute exactly what the capability of a USB cable is, especially USB-C cables that can really vary in capability even though they look identical. No more guessing or randomly trying several cables until I find the one that supports fast charging or fast transfers. Sometimes good quality USB-C cables are marked for speed but that is rare and even those almost never show which level of Power Delivery (PD) is supported, if any. The USB cable tester is easy to use and has a bright, clear, easy-to-read screen. It's a great value and I think everyone should have one of these. I don't know how I managed without this device. I use it all the time and plan to test my ridiculously large collection of cables to keep the good ones and discard extras of low-capability cables. The only thing I didn't like about this USB tester was that the screen turns off after a minute or two if you stop pressing the function button, but the device is actually still powered on and will completely discharge the AAA battery unless you also switch the power off. It's easy to forget to switch it off when it looks like it's already off.

I have been using for only three weeks, but it shows so far made with good materials. It does what it is intended for, it helped me to classify and also in selecting to throw many cables I had accumulated through the years.

This is one of the best "devices" that I have purchased in Amazon. I have so many USB cables from different types and either for charging only or charging and data or fast charging or high speed data transfer cable. Now I know everything what's their capabilities. This is very handy device that must have available to anyone because specially now the USB-C is very confusing and so many types and so many pins and also the emarkers, not like those previous USB A, B, mini, and micro have only 5 pins and the USB-C have 24 pins with different capabilities.
