Cable Tester Board for HDMI Cable Tester Checker 20 LED Light Status Indictor to Check Disorder Short Open and Cross Connection for Standard HDMI Type A, Mini HDMI Type C, Micro HDMI Type D

Works well for me. In my experience, 90% of HDMI cable problems I've encountered are due to broken wires in the cable, with breaks typically being at or around one of the connectors or just past the strain relief where there may be a sharp bend or kink in the cable. This is a quick and cheap way to check for breaks in the cable, and because it runs a continuous continuity check, you can "wiggle" the cable to see if one or more connections open up when twisted. I like it better than an older HDMI cable tester I have, because it shows all the connections at once, rather than cycling through them one-by-one like the old tester.It offers mini and micro HDMI ports, so you can test those weird cables you get with some cameras and video devices. And, it has a lithium coin battery so it is portable, although it does have a USB power input as well (just remember to keep the power switch turned off when not in use). The only negative is that it is an open frame circuit board with a transparent shield over it, not a closed box, so you have to be careful and gentle in handling it. But given the cost, that is something I can live with.This is not something you use to test an HDMI cable to see if meets specific HDMI version transmission standards; it is simple "light box" to check for broken wires. It is very similar to the old RS-232 "breakout boxes" we used back in the day, without the wire jumpers.

We needed a small, reliable tester for HDMI cables at a reasonable price. This wasn't for a business, just occasional household use. The basic, no frills, little tester has been accurate in our small sample. It quickly identified both good and bad cables which saved time in troubleshooting faulty devices. We actually like the look of the exposed circuit board and simple design.

It is a convenient cable checker. It can detect open circuits so don’t need to use a DMM to check cables. As the design to plug in cables on opposite edges, it can only be use with 8 inch or longer cables. I have some 6 inch cables that can’t use this tester.

Excellent tester, quick, easy, and accurate. Even some of the best quality cables don't have ALL the wires internally, this will show that.Also good for broken wire troubleshooting.

Well made. Super useful and convenient to use. Recommended!

How can it be any simpler, and without any tester issues. With a dual power source you are able to use on site, or at your workbench. Just do yourself a huge favor. Actually read the instructions. Once you test one cable, you will be testing cables you have used for years. Just because you can not be too careful, and besides it is just so much fun. Makes you wonder how you ever got along without this little jewel. You trashed how many cables, because you thought each had issues? Now you can be positive about every HDMI cable. Well I know what my son's next gift will be. Just like the multimeter, this is a tester every home should have.

Excellent testing device 👌 it was what I needed to verify working cords

I really like this tester. It worked right out of the box. I assembled the acrylic cover onto the board, using the supplied screw terminals. Removed the battery saver, switched it to battery and tested my cable. Yup it was bad, within 5 min I found two bad cables. One even had two connections bad. This is a must have to troubleshoot HDMI cables. It works perfect.
