The standard is also just terrible even if followed to the letter. The connectors are just too fragile for a day-to-day interconnect, and a fire risk when higher currents are involved.
I've now had to replace 2 USB-C host ports (on expensive Apple devices, where an "official" repair would cost ~50% of the value of the device) despite taking reasonable care of my devices (under which care no other connectors ever failed).
Examining them under a magnifying glass showed that the metal pin delaminated from the plastic middle part of the host connector and was ever so slightly skewed towards the adjacent pin, presumably making enough contact/interference to make the whole thing fail.
In a sane design, a misalignment/skew of <1mm would be well within tolerance and would be a non-issue. Worse, despite the machine being from the same brand that ushered all this crap onto the world, there is no software support or notification to say that something is wrong - the machine just silently stopped charging after a random delay. Very annoying when you plug your machine in to charge and only realize (at the most inconvenient time) that it silently stopped charging and you've now drained whatever battery was remaining.
Even with the new ports, I can make it lose Thunderbolt/DisplayPort connection by bumping the connector. It's probably a mismatch of tolerances between connector and port (maybe my cables are out of spec), but it's never been a problem with any other connector.
- petee 3y agoAre you using Apple, or major-vendor cables? Im curious because delamination of a pin on 2 separate ports implies something catching/dragging on it, maybe there is something either poorly designed, or simply mangled in the end of one of your cables.
- Nextgrid 3y agoMajor vendor cables, and the delamination was one connector's "finger" so not really cable-specific. The second connector looked fine at casual glance but there was something wrong with it as it wouldn't even hold connection with a USB2 device - too much slack. I don't recall having this issue with any of the connectors it replaced. I have devices that are close to a decade old and all their USB/Ethernet/HDMI ports are still working just fine. It's a terrible design that prioritizes form over function/reliability.
