Treedix USB Cable Tester, USB C Cable Tester, Usb Data Cable Checker Board for USB-C, USB-A, USB-B, Micro Mini Lightning Cables, Quickly Sort Out the Heap of Usb Cables by Checking the Leds

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

I bought the one with the transparent cover, glad I did, it helps protect it from people like me. This is a super little device, simple and easy to use, and within half an hour I had sorted my 50 or so cables, and found the vast majority were not data cables, and those that were, all but one worked fine. Very good value for the money, and worked on all the cables I tested. There are some that are not compatible, but the PCB would need to be huge to accommodate everything, but this is great for all the usual ones that plug into a PC.

Useful to identify if cable has USB 2 and/or 3 data, or dodgy connections. I found one cable with no shield connection, and iffy other connections, a USB-A to USB-C cable with only USB 2 D+/- connections, and various cables with no data connections. I assume the ID LED is for micro USB OTG adapters. It would have been nice, for this to also included an estimated display of the total cable resistance of both power connections or the maximum power they can carry at 5V and higher PD voltages, for in-specification voltage drop; this requires measurements at both ends of a USB cable. This maybe cheaply estimated using a tiny microcontroller with multiple ADCs, to measure total cable voltage drop for the supply current to and from both the VBUS and GND LEDs (loads), to allow calculation and display on a tiny LCD or OLED display. I don't know if the active USB tester, of this brand, provides such power capacity estimation with its active data testing, and is limited to USB-A/C to USB-C testing.

It's a very nifty little tool. Very easy to use and easy to read. You don't need much more than this. It has a lot of functions and you can test a lot of types of cables.

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.

The one I ordered from Amazon never turned up, so managed to find one on eBay. Amazon did however give me a refund. Build quality seems great. Easy to use and works well. Particularly useful for cables with a USB-C connector, which can have many configurations depending on their use and orientation.

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....

What a nifty nice device. Sorting the stash of cables finally happened

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.

Produkt zgodny z opisem, bardzo dobrej jakości, działa poprawnie. Szybka plexi też jest OK, tylko trzeba najpierw usunąć szarą ochronną nalepkę z dwóch stron.

Très pratique, voire indispensable pour faire le tri dans ses câbles : tester leur état et connaître leurs caractéristiques (charge uniquement, données, transferts haut débit...). Franchement top !

basicamente funziona benissimo. Es cavo usb per HDD ok , ma sapere perché certi cavi caricano iPhone e certi no non l'ho ancora scoperto comunque fa vedere v+ e v- dati ingresso si uscita no ?
