Nobody mentions that USB-C enabled the production of laptop power banks. They are such a help for when you travel and want to work on a long flight or a train ride. Power rating is a mess, and manufacturers are all trying to mislead the consumer as much as they can about it, so I agree, it's a mess if you don't research it thoroughly. But I do research it, and my life is much better with it.
