[1] The standard defines an AC adapter to power devices requiring from 10 W to 130 W (~20 V × 6.5 A) or (extended voltage option) up to 240 W (60 V × 4 A).
When asked about deployment in 2019, the chair for IEEE 1823 working group wrote the following: Currently the IT market which 1823 standard was originally intended had been swayed by USB SIG to use type C connector as alternatives.
However, EU standard body had made inquiry to see if 1823 should be considered as the preferred connector for the next generation of mobile devices.
Also, there are new interests from some automotive industry players that are looking at distributing DC bus inside a car (obvious that 1823 with CAN Bus as control method is preferred than USB type C which was not designed for harsh environment).As for commercial deployment, unfortunately I don’t have a definite answer for you.
Several power supply vendor in Asia had made prototypes about 2 years ago but I did not get any further updates after that.The Standards Association of the Institute of Electrical and Electronics Engineers (IEEE) approved the Universal Power Adapter for Mobile Devices working group on June 17, 2010.
