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

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.

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.

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
