Not quite on point, but I hope someone soon creates a small adapter with a USB 3.0/3.1 Power Delivery-compatible plug on one end, and my laptop's charger plug on the other end. Then I'll be able to invest in a very high-quality 100-watt USB power supply that will work with any legacy laptops I have lying around. I expect all my future laptops/mobile devices will be Type C/USB 3.1, so I'll keep using that power supply for many years.
