> 2hrs battery, on a flight can you even carry those... Most flights have plug sockets now don't they, you're sitting down in a confined space, it seems fine to plug it in. Any even if you can't plug it in, I'd guarantee it'll be below the 100Wh restriction that almost all airlines use, there aren't really any consumer electronics batteries above this precisely because you can't travel with them. They would also be huge and heavy.
