Another Maker's tester tests about any cable you can think of. He's very talented & his tester design shows it.

I was very tempted when you showed this on a mailbag or perhaps it was the video where you talked about a bunch of cool things available. I decided against it because I knew it was missing two of the cable types I have and want to test. It is annoying to have so many USB "standards" I've eliminated the need for so many cables by having only USB "A" to "C" cables for my PC and "C" to "C" for my laptop. I have a bunch of adapters to accomodate the various other connectors. I don't like having extra points of potential failure on my power/data path but it has worked well and it keeps the number of cables I need on hand to a minimum..

Handy little tool. I've found a lot of the cables in my accumulation were power only . And a few that had one of the data lines broken.

I like the short ones for charging my phone with a power bank in my shirt pocket. The nice thing about shorter cables is you don't get power loss like a 10ft cable that some people like to use

I use a "Treedix USB Cable Tester, USB C Cable Tester, Usb Data Cable Tester 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 ", checks all the pins -now I know which cables are power only, which USB C are only USB 2 connections and which are 10Gbs. Brilliant. Saw it on Andreas Spiess youtube channel

Another cheap and good way to test cables is to use a network cable tester which you can get very cheaply and make your own ends for it. It can also show miswirings and shorts. The tester is usually $10 from your local hardware store or $3 from China. There is a 74 series counter IC in there and an oscillator, like say a 555 timer or something like that, very simple, mostly plastic, doesn't need to be turned on and lasts an eternity on a battery since the cable connection turns it on if any of the pins have continuity.

I've got one of those hiding somewhere here🤣

6:15 Nope. You can still use it for charging.

Micro usb has 5 pins. The fifth one is for detecting "on the go"

It's disappointing just 10 years ago I didn't have to think about that. All cables were capable of provigind D+/D-, 5V 2.5W supply (USB 2.0). Some of the cables were probably not that reliable aftrer the extensive use. But in general everything worked. Now with type C I always should guess how many diff pairs are missing inside the cable and how much Amps the VBUS/GND wires can resist until the cable melts.

I recently picked up the same tester, saw it on Aliexpress when I was browsing around, haven't tried using it yet.

Sorry, but you need a better tester. This tester only tests for power and old-fashioned (slow) USB2 data connectivity. Look for a tester that tests many more cable connections!

Looks to me like this is a simple continuity tester, just to confirm if the relevant pins are connected. True you could get something more sophisticated which would measure data speeds and perhaps voltage drop and max current capability, but it would be far more expensive. For going through a stash of USB leads and weeding out the ones which have failed, I think this would be perfectly adequate and useful.
