Review: A Great Tool for Testing and Identifying All Types of USB 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.
Review: Very cool and useful device - This is really a cool device. Shows tons of useful information you did not know before and enables you to select the right cable for the right purpose. Light, small, easy to use, but still very useful.

## Features

- 【USB Cable Performance Testing】Test USB cable continuity, functionality (charging, data transfer, high-speed signal), and measure internal resistance for power efficiency. Verify ground wire connection to outer shell for cable integrity, safety, and shielding.
- 【Type-C eMarker Chip Reading】Reads eMarker chip parameters in Type-C cables, providing detailed performance information (e.g., maximum current, voltage, data transfer rates) to help users fully understand cable capabilities and ensure safe, efficient device usage.
- 【High-Definition Color Display】 The USB cable checker features a 2.4-inch high-definition color display. With the left white button, you can easily switch between function pages to view real-time detailed status of the cable, including internal resistance, power delivery efficiency, and cable quality. This helps you quickly identify inferior cables.
- 【Wide Compatibility】The usb tester can accurately identify and verify USB cable versions, including USB 2.0 and USB 3.2. It integrates PD 3.0 and PD 3.1 protocol detection functions, enabling quick verification of whether the cable supports the latest PD 3.0/3.1 standards, ensuring the cable meets high-power charging and fast data transfer requirements.
- 【Multiple Power Supply Options】The black button on the left can flexibly switch the power supply mode, and support the use of AAA battery or Type C 5V to stably supply power to the USB tester

### ⭐⭐⭐⭐⭐ Figure out what all those USB-C Cables are good for! Easy to use.
*by K***Y on June 14, 2025*

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.
