I was going to criticize & point out how usb-c chargers at and over 100W are just so small, but there's a photo comparing it to an iphone & ok, it looks adequately impressively dense! (I have a >2 year old 100W charger that is 66x64x30mm, this 250W unit is 170x50x25)
It's been such a great synergy. Energy efficiency has been a concern already yes, but I really view usb-c chargers as pushing the consumerization & massification & development of this technology to the superb, common, un-exotic levels it's come down to. We just got tired of doing less good, actively explored trying to use a somewhat harder to drive switching semiconductor, & have reaped great rewards. Miniaturization mandated optimization & we all win. I really think the interchangable-parts/modularity & resulting competition that usb-c begot started this ball rolling.
(Hoping USB-PD, with it's bump from 20 up to 48V, once again proves another huge win!)
