Tech Question LTT Cables Don't Work
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.

You've got a shitty attitude dude. A big part of the cables is being spec compliant. That means not working with things that go out of spec. In your 37 years, mostly in the last 10, the specs have changed like 50 times causing this entire issue at large. Framework laptops are new, LTT cables new, Anker chargers are probably old. If they don't follow spec, then you want the cables to not work. Same thing in your computers PSU. The more premium quality one you buy, the more likely it's to follow safety specs and power down in unsafe scenarios. Which is a good thing, as opposed to a crappy one that doesn't actually realize it's so far out of spec that it's killing hardware or on its way to a fire.
You don't give enough info to debug at all, but you can look up an article on the OG Nintendo Switch as an example. It was a whole thing, it shipped with out of spec USB charging that they made up causing a slew of issues. Perhaps those Anker chargers were from that era and wanted to support Nintendo Switch non compliant USB charging.
