The whole 100W thing was, as far as I can tell, an almost completely unsupported theory advanced by a Mac blogger about why Apple doesn't put bigger batteries in their laptops. There is apparently some FAA document saying something to that effect, but of course there are lots of regulations on various books that are unenforced or unenforceable, and there have been dozens, maybe hundreds, of laptops made over the years with larger batteries, and none have ever been, to my knowledge, barred from flying.

- deong 10y agoI remember seeing the link in the original blog post, so I knew it was a real thing, but I'm extremely skeptical of the theory that it has anything to do with anything. The simple fact is that the FAA doesn't screen battery sizes. If you brought something the size of a car battery, they'd probably not allow it, but the difference between a 95WHr and a 140WHr laptop battery is something they're neither interested in nor capable of actively checking. Apple put a small battery in the laptop because it's more important to them to have a thin light laptop than it is to have more battery life. This random person unaffiliated with Apple then decided with no evidence that it was because of some basically unknown FAA document. That's all I meant.
