Asking for 12V up the jacksie, that one. --- End quote --- Funny you should mention that. My brother in law made that mistake - chopped off the 'accessory' (cigarette lighter..) plug and hard wired his dashcam. It didn't survive the experience. One switching regulator, two LDOs, and a BGA DDR2 IC later (that one was fun), it lived again. Good practice. |

If there's a desire to have a common power port then a circular barrel jack is far superior to any USB connector. Impossible to put in upside down, rugged, durable, lasts virtually forever. If you want a standard, then just pick one size. I understand that it wouldn't allow negotiating for different standard voltages, but if a third terminal is available for analog feedback, then the supply could provide any DC voltage over some range. But all of that is moot because whatever the law says, it's really about getting Apple to replace their proprietary connector with USB C. The goal is to achieve that by any means necessary. |

How do you put USB-C in upside down? |

Ok, here is a task for you all. Look at a few of the larger power supplies you have. Count the number of approvals marks on them. I lost track at 25 on my latest supply. Everyone and their cat has an approvals requirement of some type. The vast majority of these are safety and EMC approvals. There are also environmental requirements for RoHS, etc. However, there are not any applicable approvals when it comes to specific components. Now consider that the EU is requiring a specific type of connector. This has nothing to do with safety, EMC, RoHS, etc. The claim that it's reducing electronic waste by narrowing down to a single connector is without merit. There are other problems that are much worse. So if the EU can specify USB-C, what is to prevent China from specifying some other connector? The USA from specifying yet another? For al global product all three would need to be included. All for the same specious claim. This is the key distinction. Safety, EMC, and RoHS leave open any realization within the requirements of the standards. This requirement for USB-C is an entirely new avenue. |
