USB-C can on do the following on the same cable at the same time
1. Charge 2. Data 3. Video
Your power cable can
1. Charge
How is that "orders of magnitude" worse?
I've done replacements of barrel plugs and also USBC ports and the barrel plugs are significantly easier to replace.
Now my USBC charging ports haven't failed me yet, i think that's probably because i have 4 of them on my laptop, and i charge from different ones depending on multiple factors. So I'm spreading the wear around.
That said. When one goes more than likely the others will go shortly there after.
For example my framework laptop USB C ports are replaceable (for the laptop side).
Also you can buy magsafe like connectors for USB C if you have a regular laptop.
Having one USB C charger for my phone, my laptop, my earbuds, my battery and my remarkable is such a life improvement on trip vs the old barrel connectors. It just doesn't even compare. And we just talk about charging here, one of the multiple uses of USB C.
I have two laptops. One with a old school barrel plug and the other with USBC, and the USBC charges faster as it has more wattage.
So.. id like to hear how you define worse?
As the GP said: the cables are less robust and break more easily.
This is not a limitation of the barrel plug, it's a limitation of your laptop or charging brick not being able to use or provide a higher rate. I have a barrel plug laptop with a 170W adapter. USB-C chargers above 100W move into 'exotic' range and none go above 100W at 20V, the cables can't move that much current without heating up.
If we replaced the usb-c charging port with a normal charging port you would permanently lose it.
I didn't call it orders of magnitude worse. I called it orders of magnitude more delicate and prone to falling out than a bespoke laptop charger like a ThinkPad Slim Tip connector. Why bother misquoting me when my comment is right there?
