I saw the recent RDR-928 product announcement on e14 and thought I would take a minute to record the physical size and power density of my current collection of USB-C chargers.
All of my USB-C chargers have programmable output voltages via the USB-C power delivery protocol. Some also have quick-charge or the programmable power supply control interfaces as well.
The power gang (original Apple 5W charger included for nostalgia)
The size and power ratings are in the table below:
UGreen 30W
Amazon 30W
China QC09 45W
Presumably, the RDR-928 would fit in the same enclosure as the amazon supply and provide twice the output power, pretty neat.
Aside, Ken Shirrif has a wonderful teardown blog of the original Apple 5W USB charger https://www.righto.com/2012/05/apple-iphone-charger-teardown-quality.html
