Guides like this explain why there are so many broken USB-C devices. The guide mentions that you do not need a PD chip for 5Vs, but then tells you that USB C is a cold connector meaning 0V is on VBUS when nothing is connected and jumps straight into the complexities of the PD protocol running over the CC pins instead of explaining how to get the 5V without the PD chip first. Then in the section where it tells you how…

Now I want to know, how to add larger than 10uF cap?

My new iPhone with USB C charging is such an improvement! Thank goodness for the European Union. If it weren't for them, we'd all be stuck with these flimsy Apple charging cables forever.

There were non-apple lightning cables already.

And I have to say, the lightning connector itself is better than the usb-c connect in my opinion. I get that having the pins on the male* plug is a theoretical advantage in durability but that has not been my experience with usb-c connector durability on either end.

EDIT: usb-c has pins on the male plug. Which is what I meant. So female -> male.

That's fascinating; I've only had positive experience with USB-C cables and terrible with Lightning. What kind of cables do you commonly use?

My phone's USB-C port is worn out, and so now it's a brick if I don't have a wireless charging dock around.

Is it physically impossible to get bandwidth and power out of something as durable as a Magsafe connector, even a larger-scale version?

Couldn't be further from my experience. They would always eventually stop connecting.

I didn't mention the single cable for everything advantage, that goes without saying.

I've also had basically zero issue with Lightning connectors, but had a constant battle with USB-C of every kind to figure out what's charging, what's data, what's PD, and so much more hassle.

I don't get why Apple was forced to colonize by the EU when they had the market-leading connector in place for significantly longer than USB-C even existed.

"It's only USB2!" Does it have to support the faster USB3 speeds? Not really... we don't have to keep forcing everything to include the latest kitchen sink support.

Even if Lightning was possibly a nicer or smaller connector; nothing beats a true industry standard. Makes the entire “what chargers and cables to bring to connect my stuff” question so much easier.

I always end up picking a lot of dust out of my usb-c ports on my phones; or otherwise the port wears out and disconnects before charging completes. (Right after my wife entered the hospital in labor, I needed to scrounge around for something to clean out my phone's port because the "go" bag only had a wired charger and my phone wouldn't charge on it.)

It's why I went to a wireless charger for daily use.

I'm real curious why lightning never became the standard. Was Apple trying to keep it proprietary? Was there a half-hearted attempt to open it up or otherwise convince the Android ecosystem to use it?
