Treedix USB Cable Tester with LED for Lightning, Type-C, Type A/B, Micro | USB Tester with Acrylic Case, USB C Cable Tester for Quick USB Cable Testing by Checking the LEDs

Good quality, good value for money, easy to use and very useful.

Need small fingers to assemble the case but looks good when complete. Would be good to have a link to more documentation for the 'whys and wherefores' but overall good item

It works great except the lightning connector is a little iffy. 5 stars if you ignore the lightning port...4 stars including it...1 star if you're buying it just to test lightning cables (don't)...for the price, it's well worth it just for testing all the USB variants... Also will test thunderbolt 4 cables (every led lights up one side...and if you flip the connector it'll flip to the other side....all pins are connected on a TB4 cable btw)...obviously won't tell you if it's 20 or 40gbps...but at least you know all pins have continuity...very cool. My only reservation is I think they could have used higher quality ports...the PCB and the soldering and construction is all 10/10...but the ports feel a little on the cheap side; time will tell if that's really an issue....

⚡ The box contains a USB cable tester board, a clear plastic cover, fixings, a fitted CR2032 lithium cell, and a small screwdriver. Assembly is straightforward and took only a few minutes. The screwdriver is included but not really required. Peeling the protective backing from the plastic cover takes a little effort, though it does not cause any real difficulty. There are a lot of LEDs here and with the connectors arranged to the sides, the board is sizeable but there is no wasted space. There are clear labels printed on the board itself. 🔌 The tester supports a wide spread of connectors, including USB-C, USB-A, USB-B, Micro USB, Mini USB and Lightning. For me, this breadth is the main strength. Many USB-C cables look identical while behaving very differently, and this board makes it easy to see which internal lines are actually connected. It is a low-power, passive device that simply lights LEDs to show continuity, including the shield, so the results need to be interpreted rather than read as a simple pass or fail. ⚡ Power can come from the supplied CR2032 cell or from an external supply between on a separate USB-C connector, with a physical on/off button for battery use. I like the dual power option, as it keeps the tester flexible on the bench. The LEDs are bright and clear, making it easy to see the status of each pin without straining. 🔌 In use, it has worked well for my main purpose, which is checking whether data paths exist when using chains of adaptors in test setups. It quickly shows whether a cable is charge-only, missing lines, or wired for higher data rates. It is strictly for cable testing and should not be connected to active devices, which is clearly stated. ⚡ At £14.99, it feels like reasonable value against similar cable testers, given the connector coverage and clarity of the LED indicators. Some of the marketing images showing obviously broken cables being tested are unrealistic, but that does not detract from how the product performs in real situations. Long-term durability will depend on how often it is handled, though so far it feels adequate for light to moderate bench use. It does not go back in its box with the plastic shield and stand-off posts in place. ✔️

Every person should have one. This has to be one of them gadgets many just do not want to be without, You are most certainly at a great disadvantage not having one. There are a number of positives about this unit in what it will do for you, the main one is a "What If" You lost your lead to your phone, needing desperately to download or upload something to or from your phone. There is a spare cable that will fit your phone. However, Is it a Charge lead only, or Data and charge lead? As you may already know if it is a "Charge Only" lead you wont be uploading or downloading data because it won't register on your device as a Drive. So now test all them cables to figure if its a data cable or a charging only cable. You probably have tons of charge only leads, Time for a sort out. The beauty about this unit is it tests for shielding. This on its own was a reason i purchased the unit. I could not find the original cable anywhere for a Peterson Guitar Tuner Unit, so was using this cable i had lying around, anytime this unit was connected it always had a noise, irritating but could never source where the noise was coming from but it was definitely this cable, why? Turned out the cable i was using was not shielded! Immediately I found and tested another cable the sheilding light lit up. I then tried that cable the noise was gone. I am sure many will find this unit useful, but for this purpose also as there are many USB leads out there of the various size that this unit is there to test and many have no shielding. Working in a recording enviroment " Unwanted-Noise" is something you definitely do not need, even low frequency noise. Well designed a lot of thought has gone into this tester, It looks an awesome bit of kit and does the job as intended. Just take care connecting leads to it as not sure how strong the soldered points are to the board, especially if you have a box of leads to test. When inserting or removing keep the socket on the board your plugging or unplugging to between thumb and finger, just to give more support. Overtime these soldered joins might loosen, so USE WITH CARE. It isn't the invention of the "Wheel" but its certainly very close, should be certified with an award for Ingenuity, Design, A product you are at a great disadvantage not having.

As many people, I have lots of various USB cables at home of different origin, quality, type, speed rating and plug geometry. Oftentimes, it is frustrating to figure out why a particular cable does not work as expected - is it because of problem with the device I am plugging it in, because it is charge only, maybe it is USB 2.0 while the device requires 3.1 or just faulty. This nifty self-contained gizmo removes the guesswork - it quickly tests cable (and has connectivity for seemingly every conceivable USB plug variation), displays it compliance, maximum rating and status of actual individual data and power lines. So you have all the information at a glance. Very illuminating, fast and convenient. And the fact that it uses own onboard battery and hence requires no external power source makes it doubly convenient.

Hi Please see my photos that accompany this review, they can be informative. The second one in particular shows what appears to be a light brown piece of card. Well that turns out to be the clear acrylic cover with a peelable brown protector that you need to remove..! For the cost the testing unit seems to be very well made and comes with the stand and cover, see photos. In my opinion it is worth paying a little more for those. The board itself has enough printed information on it to be useful. The detailed two sided manual is very well written, one side information about the board and how to power it up etc. The other side about the pin outs for each of the connections, well the LED lights. I have included a photo showing a USB 3 based cable connected and the corresponding lights that the board displays. I am still learning as to the boards full capability, but that can be understood in time. My only very slight concern is the need to be a little cautious when plugging and unplugging your leads. Perhaps a touch of hot melt glue to hold them in place might be useful, so far they seem fine. Overall a very useful board and a very good price. I very much recommend this USB cable tester. I do hope that this review has been useful for you.

This device will clearly show you which pins on each end of the cable is connected (or not). This will help you determine if the cable supports data transfer and if so, at what speed (USB2.0, USB3.x, Apple Lightning) and also show this for multiple types of connectors (micro-USB, mini-USB, USB-A, -B and -C). You have to get familiar with what the different pins mean because it doesn’t tell you, you will have to deduce it from all the different leds that light up or stay dark.

teste plusieurs cables, en utilisant la batterie, et fonctionne parfaitement. Pas teste avec une alimentation externe.

I had a huge tangled pile of cables filling up a drawer and now I have cut it down to six! I am not an electronics expert but, with the very good little manual, you soon get the idea and can sort out cables which are not working and which are, say fast USB-C or USB-A 3.0 and which are the older and slower 2.0. It allows for a wide range of (male-to-male) combinations: from (at one end) USB-A 3.0, USB-A 2.0 and USB-C to (at the other end): USB B 3.0, USB-C (2.0 and 3.0), MicroB 3.0, MiniB 2.0, Lightning, MicroB 2.0. I don't think you can test USB-A to USB-A. The LEDs show the state of all the different pins and the manual helps you work out what they all mean. I felt like quite an expert after about 10 minutes of mucking about... The tester comes with a coin battery (you can in also plug in a power adaptor, which you'll have to source. I'm not sure it's worth it, unless you're going to test many hundreds of cables). This means you test the cables themselves: you can't plug them into devices and test them in action. This also means you are testing the type/speed of data connections and whether there is a power link. It won't tell you directly what the voltage/power capacity of the cable is - you have to infer that from the cable type (eg USB-C is 60W+ at 20V) or get a power meter. I recommend spending the extra €2 for the acrylic top, which is easy to fit. It looks a bit Heath Robinson but is actually a great piece of kit at a low price and much easier to use than I feared.
