Try your definition of “slow” on a iPhone 12 Pro Max using a cord that only delivers power over 5W. Better yet, try charging an iPad 12” Pro (that does have a USB C port) with a USB C cable that can only do 5W. Now try to use that same “standard USB C” cable to charge a 16 inch MacBook Pro.

Of course that standard cable is not guaranteed to support data at all.

So much for a “standard”.

iPhone 12 Pro Max has smaller battery than my 5y old Nokia, so I would not worry about that.

And how long do you think it would take to charge?
