I’ve had it with shoddy c ports on various devices, including a phone (thankfully had wireless charging also). The connection pin thingy breaks off pretty easily, and causes the same issue you described for several weeks/months ahead of the actual breakoff, where it has to be in exactly the right position (and wiggling it to hit the right position obviously exacerbates the problem).

I’ve actually bought some magnetic chargers for the more fragile electronics, so I never have to put strain on the port…
