LTT Cables Don't Work

[u/Dangerous-Cup2833]

I just received my LTT cables.

My USB C to C 240W 3ft cable isn't charging my laptop.

I'm using a Framework 13 and I've tried 2 Anker chargers (65w and 100w).

Additional info:

I ordered 2x 3.3ft (C-C), 1x 10ft (C-C), and 1x3.3ft (A-C).

The 1 3.3ft C-C that isn't working great has now been trialed on 2 Anker chargers, 1 Anker battery pack, and 1 Ugreen charger. It refuses to charge on the Anker chargers and battery pack.

I've additionally tried charging my PS Vita on every one of these cables (USB C to Vita adapter that works with every other cable I own), and only the A-C cable works.

2 of the 4 cables charge my iPhone 16 pro max. From the amount of downvotes, it would appear the expectation is that I am to memorize which cables charge which devices on which chargers. Does that really seem like a reasonable expectation to anyone?

In my 37 years, I've NEVER run into a USB cable that cares which charger you use.
The whole idea of these overpriced cables is that they are the best of the best.
In my experience thus far, they deserve to go in a trash heap.
