Review: A very useful and easy to use tool - This is a very nice device and provides a lot of useful information. It is easy to use and easy to read. It comes with a small instruction booklet that is quite clear. The basic process is to connect both ends of your cable to the device and slide a small switch to the desired power source (included AA battery or external USB C power source). There are four pages of information and you step through them by pressing a small button. The first page gives you a summary of the protocols supported (e.g., USB 2.0, 3.2, 4 and Thunderbolt). Note that it does not report the "generation" of USB 3.2. Your computer might have USB 3.0, 3.1, 3.1 gen 1, or 3.2 gen 1 interfaces - these are all equivalent to 3.2 gen 1 (5 Gbps) and the "USB 3.2" indicator that will light for cables that support that. However, it also will light for USB 3.1 gen 2 and USB 3.2 gen 2 (10 Gbps), and for USB 3.2 gen 2x2 (20 Gbps) cables. The fact that 3.2 lights up indicates it's at least 5 Gbps but might be more. The second page shows the wire connection list between the two ends of the cable. The third page shows some resistance and latency information. The fourth page shows data from the "e-marker" chip, if present. These chips are embedded in some USB C cables. If present, the e-marker will report the max data rate and the max charging power supported. If you have USB A-A or USB A-C cables, or USB C-C cables without e-marker chips, you won't be able to tell whether they are rated for 5 (gen 1) or 10 (gen 2) or 20 Gbps (gen 2x2). If you have a cable with a chip, you will see the maximum data rate on the fourth page. Note also that if you want to evaluate a USB A-A cable, you'll need a USB A to C adapter plug. The unit has a wide variety of USB 2.0 connectors but only one Type A USB 3 connector. To perform the tests, both ends of the cable have to be connected to the device so you must be able to adapt a Type A connector on one end of the cable to a Type C. Overall I recommend this, but I wish it could tell which USB A-A 3.x cables support 5 (gen1) or 10 Gbps (gen 2) interfaces. I suspect it is technically impractical to determine that in a low cost device. I found that almost all of the USB C "charging" cables I have lying around have no e-marker chip and no data capability at all or just USB 2.0 480 Mbps. An e-marker chip is required for any cable that supports 60W or greater charging; any cable lacking the chip must necessarily be rated for <60 Watts, but you cannot tell whether it's 15, 20, 30W, etc. Lastly, the device comes with an AA battery. You can use that to power it, or you can plug in a power source via a USB C cable.
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.

## 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
