Portable vs installed wall unit — the 5-year cost math nobody talks about
I ran actual numbers before doing anything, which is apparently unusual around here. Wallbox Pulsar Plus hardware runs about $700, installation quotes I got locally came back between $900-1400 depending on panel distance, so call it $1600-2100 all-in for a proper wall unit. A decent portable Level 2 is $500-650 and comes with me.
I move for work roughly every 3 years, always renting, never owned the place I've charged at yet. Amortized over a 3-year window the wall unit is somewhere around $45-58 a month once you factor in that I don't get a dime of that install cost back when I leave. The portable is maybe $18 a month over the same window if I use it for two full moves before it dies. Am I missing something the wall-install crowd knows that I don't, or is a chunk of this forum just paying for permanence they don't actually need?

Wall units usually pull higher continuous amperage than portables, 40-48A vs 32A on most portables, so if you've got a long commute or a bigger pack you'll actually charge meaningfully faster. For someone doing normal daily miles that gap doesn't matter much though.
That was in my numbers too, difference between 32A and 40A is about 20% faster, but since I'm always fully charged by morning either way the speed doesn't translate into anything I actually use.

The other side of your math is resale and home value if you ever do buy. A permanent Level 2 install is a small selling point on a house listing, a portable in a drawer is not. Doesn't apply to renters obviously, just flagging it for anyone reading this who does own.

Also worth weighing durability, a lot of portables aren't built for being plugged in outdoors every single night for years the way a wall unit's housing is. If you're charging in a garage it's a non-issue, if you're outside in weather that math changes.
Fair, I charge in an attached garage so that variable doesn't hit my numbers, but I should've flagged that assumption in the original post.
