> I have a power inverter, meaning I can use appliances with normal/household plugs, but the inverter wastes some power in the conversion process, stepping up from 12V to 220V. To then plug in a power brick, which will again throw away some power in converting 220V back down to whatever voltage a device uses, means double wastage, and a mess of plugs and wires.
Is this... a joke? How much freaking amps are you pulling? Average Canadian electricity consumption is 1270 watts. 1270 / 12 = 100+ Amps for one hour.
I'm guessing this is more of a third world situation and that electricity usage is much lower, but still...I fail to see how you would get to a setup like this. If you're fully off-grid then your generator or solar system could give you much higher voltage. If not, how are you charging the battery bank?
EDIT: From your CV, you are from the UK. I'm very confused.
Lives in a caravan and avoids using mains power.
I have 800W of solar panels and a 3.5kWh LFP battery bank.
I use approximately 2kWh per day in summer, 1kWh in winter, 500Wh when it's cold enough that I can turn the fridge off.
In the summer I dump any excess to an immersion water heater.
At that level the self-consumption power of an inverter, about 5-10W, is significant so I avoid relying on it for anything powered all day (but it's useful for appliances, power tools and other intermittent items).
Using incredibly wasteful amounts of energy isn't necessary, people just do it.
-laptop lid closed/open sensor.
-no lid screen at first boot was a pain to fix to external monitor.
-logic board only on first boot requires macbook pro trackpad and keyboard(case), connecting external keyboard and mouse doesn't work at login screen due to security.
Once up and running though it is an excellent, cheap compiling/local llm machine i use over ssh from another mac
Idk. A year or two ago I wanted to test something on Mac. I searched a bit and found an image and probably copied a qemu config from somewhere, and it worked without any obvious problems. I'm sure there was a performance hit, but it wasn't unusable by any means, and I don't run the latest hardware.

Sometimes we do things just for “the love of the game” and learn something along the way but I couldn’t help scratching my head the entire time while reading this

The relative tradeoffs (hacking together monitors, sketchy battery power, etc) don't seem to coherently add up to the stated goals.
Interesting read tho.

Here’s an M1 and somewhere in this guys Insta are photos of an M2 which is even easier as the cable is easier
