Probably an M1 Max -- afaik the Ultra is only for Mac Studio desktops. I use a Gigabyte M28U monitor, which has 16W of charge. Pathetically low, but as long as I'm not compiling anything or running any especially heavy processes, it keeps my battery from draining! Clamshell results in a slow charge.
