"On the other hand, if you want a solar-powered Chromebook, the inverter could be a deal-breaker on the weight."

You wouldn't need an inverter, really. In many cases, low-power laptops run on ~10VDC, so a direct solar panel connection with resistor would be roughly fine to hit the battery through its charge controller. For those needing ~20V, you just use a cheap-ass boost converter and resistor before you feed to the charging/power circuitry.

Been there, done that, made solar-powered headless laptop servers.

" Also, why they claim they will not open the box up."

And I would ask that I be allowed to personally observe my box during the entire time, if need be, to ensure that. That is all under the assumption I had such a device. I've seen it from AC-DC for LED drivers, but not that kind of efficiency in reverse.

Just about any component after the transformer will work fine, frequency independent, minus things like oscillators, radio crystals, etc. resistors DGAF, caps DGAF as long as you match or are lower than its rated voltage, diodes are voltage drops and DGAF about frequency...

Do you even basic electronics?

I just finished building and wiring up a full hydroponics building. You get ~277V, split-phase, and in reality, it's higher than that, because it's 120VRMS and upwards of 170V peak, so you're looking at a potential spread of 340V or more.

"There really isn't any such thing as 110V or 230V in the USA/Canada,"

From a technical standpoint, yes. From a practical standpoint, not really. RMS is good enough. Trust me, if the electronics we have were not that robust, they'd have been fried long ago. Hooray for tolerances.

"Actually, with the fins being on the outside for this design, I think it would be less efficient compared to jetboil."

Nah. The fins up the side provide more surface area to capture waste rising heat. This also allows for better and more even dispersion of heat throughout the surface area of that which you are cooking, since instead of only heating the bottom you're getting the sides as well.

Jetboil still suffers from having the fins being confined to the bottom.
