What's incredibly exciting about USB power delivery is that it offers a glimpse at a future world with a common, unified electrical socket. If you go into a house, and there's a USB-C port on the wall, it can be used by anyone, anywhere in the world, for anything that charges through USB-C.
Sure, at the moment, the supported voltages are relatively small. But over time, they will increase, and more and more gadgets and appliances can be powered through USB-C, the utility (network effects!) will only increase.

- wjnc 4y agoThat has to be one long cable to charge anyone, anywhere in the world from a port in the wall. Yokes aside, USB has been a nice unifying set of plugs but the shenanigans with versioning and reliability would make me hesitant to say revolutionary. The standard always delivers a little less than envisioned.

- xani_ 4y ago48V is most likely the limit for tiny USB-C connector just because of conductor distance
- svnt 4y agoIt’s the limit because anything above that is no longer legally “low voltage.”
