USB Cable Data Line Test Board Checker With Acrylic Case Charging Card Type-C Micro A B

USB cables come in all kinds of capacities. This lets you quickly know if a cable is for power only (apple Vision Pro for example) or whether it has data capabilities and so onIt’s interesting to use

This little gem is well constructed and will instantly tell you more than you want to know about any of your USB cables. I got tired of sorting through cables and discovering only by trial and error which could be used for data transfer, and which were only good for charging. This little gadget will tell you. It has all sorts of plugs (USB-A, USB-B, USB-C, USB mini, USB micro and one other I don't even recognize. And it also does Apple lightning connectors! Make sure you spend the extra $2.00 to get the clear plexiglas cover since it looks like it might be easily damaged while it's on your workbench and getting buried. Only thing that could be better is clear instructions. But I figured most of it out. Except for that USB port that I've never seen before. Great buy for $15. If you love technical stuff, you won't be disappointed.

Works well, lets you know cable topology very well.

Not a needed piece of gear but does work to test USB cables and show capabilities. Didn't realize there was so many variables in cables.

Pros:Make no mistake, this is a well-made, inexpensive, and useful gizmo for checking USB cables since manufacturers don't seem to be willing to clearly identify how much of the USB spec a given cable covers in its wiring (i.e., is it charge only, data and charge, for video and audio, etc). I actually endorse the plexiglass cover you get for an extra $2. It's easy to put on or leave off, with threaded stand-offs that lift the circuit board's bottom off of a table surface. The components are surface mounted except for the USB connectors, so there's little to be gained by adding more to the case (although you could, since the underside stand-offs are threaded for a screw insert to allow mounting an underside cover should you wish to do so (I wouldn't bother) I should note that the plexiglass is protected by a brown paper contact sheet you peel off to get the beautiful clear plexiglass you expect. Amusingly a small bladed screwdriver is included that doesn't fit the Phillips head nylon mounting screws.Cons:The instruction manual is minimal, failing to explain how to interpret the results for a typical cable or even how to hook it up (while for me it's pretty obvious, it might not be so for others). It's also an annoyance that the box isn't big enough to hold the gizmo with the plexiglass cover installed. My real quibble is the use of a JST PH2 power supply connector should you want to bypass the battery (or if it is dead). There is (unexplained) a switch to channel power from the battery or from the power supply input (Vin). A JST PH2 plug is a type not found in most if any plug adapter kit; i.e., you would have to acquire a plug and wire it up to a power supply since it's unlikely you already have that kind of plug on hand. At least Vin is not voltage specific (3V < Vin <12V) so you could just use one of those old 5V cell phone chargers you have lying around to convert to a JST PH2 plug (doing whatever is necessary to identify +/-).I really like the thing for weeding out bad cables and separating by type (which I diligently label using an old label maker I have on hand). The cons are annoyances rather than deal breakers. I recommend the gizmo.
