One thing I do is opportunity charge. When I'm at a place where only level 1 is available, I charge as much and as soon as I can. The last 2 years I was at a campground for 6 days with only 120V/12A and I kept the car plugged in at the start of the week until it was fully charged. If someone had unplugged me, I'd have had enough extra time to be able to charge before the end of the week.

It would be unlikely to cause a fire or damage any one time, for a short charging session, but you are talking about plugging into circuits in unknown condition. Breakers can (and do) stick on, wire connections can be a little loose, things like that. It's a safety margin that makes sense, because people rarely stay with their EVs for long charging sessions.

On a more practical note, you're in danger of tripping the breaker by charging that close to the rated value for a long period... which would both stop your charging session and draw negative attention to EV charging in that spot when somebody has to deal with the tripped breaker.

A very good point. Although a fire is a lesser risk, it also has as bigger impact. "Hotel catches fire due to unauthorized EV charging" would make headlines and have a much bigger impact than a tripped breaker.

As early adopters with powerful tools (current limiters going above usual specs), we have a responsibility to be good stewards and not bring upon ourselves negative attention (fire, tripped breaker, etc) until EV charging is commonplace and accepted.
