Wife wants a light weight level 1 charger so when she visits friends she can plug in to their plug (usually 15A standard house circiut). I've seen some chatter on Amazon about chargers that overheat and shut off because they're trying to pull 16A. Does the MINI dumb down amperage coming out of the charge to a safe level??

Your SE will negotiate with the charger to agree upon how much current to pull. The charger will tell your SE how much it can deliver and your SE will ask for as much as it can safely use--and they should agree on the smaller of those two numbers So you'll have to make sure the charger doesn't try to deliver more than is safe for the outlet it is plugged into.

The rule of thumb to safely charge is to pull no more than 80% of the circuit breaker's rating. So for a 15A circuit, you should pull no more than 10A continuously. Plugging a 16A charger into a 15A outlet without dialing down the charger to 10A is a Very Bad Idea™.

That said, you can set the SE to ask for less charging current by going to:
1. "My MINI"
2. "Plan charging/climate control"
3. "Settings charging current"
4. "Level 1 (120V)"

From there, you can select "Max", "Reduced", or "Low". This table from the owner's manual shows you how that will affect the amount of current pulled (which depends on the maximum current the charger can provide):

In theory, you shouldn't have to buy a Level 1 charger because you should have been given one with the car. My 2021 SE was delivered with a Level 1 charger in the boot. My understanding is that newer SEs are being delivered with a flex charger that can supply both Level 1 and Level 2 (depending on the kind of socket you plug it into). The Level 1 charger I got is rated at 10A, so I haven't had to reduce the charge current setting (yet). I don't know what the newer flex chargers are rated at, but that value should be printed somewhere on it.

Thanks for the info!! the car is on "reduced" right now. We've been charging it with the Flexible fast charger on the 110 15A circuit with no apparent problems. We will be using that charger on Level 2 on a 240v 30A circuit (stove circuit) and I'll leave the car on the "reduced" setting. I think I'm comfortable on that.
