I have some USB C chargers that only charge in 1 orientation. I don't know if it's my phone, or the cable, or what, but for me this isn't true.

  Same is true of Apple's Lightning. It looks symmetrical, but electrically it isn't.

    > Same is true of Apple's Lightning. It looks symmetrical, but electrically it isn't. Have you every used an Apple product? Because if you did you'd know that it doesn't matter which direction you plug it in. https://en.wikipedia.org/wiki/Lightning_(connector) https://en.wikipedia.org/wiki/Lightning_(connector) "The male Lightning connector is symmetrical (same pins on either side), so it can be inserted into a female Lightning port in either orientation."

      From an end user's point of view, there is no difference in the orientation. But from the device's point of view, one orientation has pins 1-8 and the other has pins 8-1. It's up to the device to figure out which is being used. This is still considered symmetrical though.

      It's not, though. https://www.techinsights.com/blog/systems-analysis-apple-lightning-usb-cable https://www.techinsights.com/blog/systems-analysis-apple-lig...

        The context, however, is important: the OP responded "same as in Lightning" to this: "I have some USB C chargers that only charge in 1 orientation"

    I get the point you're trying to make, but the connector is electrically symmetrical: "made up of exactly similar parts facing each other or around an axis"
