I run my 16" Pro (M1 ultra) on a 35w power delivery from my monitor daily - its plenty even under a fair bit of workload. The 95w is only used in extreme circumstances. Even compiling and light video editing isn't going to use enough to need anything more than 60w.
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.
