The larger it is, the more lever action it causes, and the more stress there is. I would say not to worry, USB-C is the result of 30 years of engineering a more reliable connector and so far the track record is pretty good. |

I have one of those cheap egg cookers that boil a quantity of water to time the egg cooking cycle and when the water runs out the thing trips a thermal switch and sounds a buzzer. But the buzzer failed and barely made a squeak. The buzzer is 240V and whilst I could have made a rectified DC filtered circuit to run a DC buzzer, which is what it does inside the buzzer, I decided to gut a 240V AC to 5V USB phone charger and attach a 5v buzzer, which I already had, and put that into service. So there's one use for an old power adapter. |

I have to mention an observation I made concerning your photo of the sink with an electrical outlet very close. A GFCI would be something you should consider for that outlet, unless of course there is one upstream, in which case... never mind. :popcorn: --- End quote --- As for the GFCI: We do have one or two in the house, and this one in my photo may well be downstream of one of those. I find that the wiring in this house is a bit squirrely in that there is much of this that I do not know before there is a problem. Recently I was amazed that GFCIs were $20 US for 2 of them. At that price, economizing in their use (doing a lot of sharing) makes no sense to me. For maybe $100 you could have one by every sink etc. and that is a drop in the bucket for the price of a house. |

IMO you are confusing length with size in other dimensions. I think the older barrel connectors are very good. But if you think of a 100W capable cable, it is too easy to accidentally apply a large force in the wrong direction, especially when powering a larger device such as a laptop. I saw some other post referring to laptops that were trashed due to a broken USB-C connector which was the only input power port. And now I just found this: https://community.frame.work/t/usb-c-longevity-is-becoming-a-big-problem/32547 I recently bought a new Rigol oscilloscope. I am amazed at its capability for $800 US. But it is powered by a USB-C connected power adapter. What do you know, the horizontal "trigger" options do not include ("Line" or "Mains")!! Hmmmm. I wonder why that is. ::) (I am kidding.) |
