I mean, I have thought hard about it, and read the first few pages of this thread to understand the viewpoints of others, but I honesty can't think of a significant real world advantage to the regulation. --- End quote --- Besides the goal to reduce e-junk there is a very practcal aspect for users: Bob: Oops, I left my charger at home. Can I borrow yours? Alice: Sure! This wouldn't work without a standard charging port (unless both have the same device/brand). Or take my father for example. He loves to plug in the next best charger which has a matching plug. Ever tried to charge a three cell Li-Ion battery with 40V? IMHO, it would a good idea to also have a standard charging port with a protocol similar to USB PD for high power battery packs, like for power tools. Two standard chargers (one as spare or for a second battery) instead of 10 different chargers, some with the same connectors, would save money, save real estate on the bench, save ressources (production) and reduce e-junk. |

Looking forward to: 1. Increasing the BOM cost of my device if I draw more than 15W 2. Having to wait a year for USB-PD parts during this or the next supply shortage 3. Noncompliant USB-PD sinks that sink 5V/3A all the time without negotiation 4. Dealing with blown up ICs because USB-C ports are prone to shorting VBUS to data lines when removing them, and not everyone puts in port protection 5. Being forced to use USB-C ports in a portable rugged device (nb: didn't check if the standard applies to them) and getting dirt/liquid stuck in them etc, etc. |

I'm thinking of the A :palm: There must be some reason though. Even fairly recent Garmins use the mini over micro. --- End quote --- I just got a brand new Garmin and was surprised to find Mini USB still alive and well.... --- End quote --- I'm not sure "alive and well" is what it is, it is discouraged but still allowed by USB-IF I suspect Garmin stick to it because there is a crapton of old holders out there that have a mini-B charging cable --- End quote --- Maybe, yes. But mini-B is a lot easier to plug in than micro-B. Sometimes I have to invert the micro-B just to show the damn device I'm doing it wrong and then put it back the right way to get it to go in. It's perverse. With mini-B they just slide in first time. But the whole question of USB as sole power on satnavs and dashcams is a puzzle. Asking for 12V up the jacksie, that one. I don't think it's so they can be plugged into a PC as well because using the same connector for that it has to figure out if there's a PC or car connected. With a 12V input for the car and USB for the PC there's no problem. |

We can thank Apple for USB-C being reversible: they pushed for that feature at the USB-IF. |
