> [!] Amusingly, my laptop won't actually charge off the _standard_ A/C plugs on most airplanes because the 100W charger blows a soft fuse that requires unplugging and replugging the A/C adapter!

To be fair, 100 W may not seem like a lot when you're used to plugging in to the national power grid, but it's a lot to ask for a non-essential system supplied by an off-grid generator shared by hundreds of passengers. And 100 W is the maximum allowance for In-Seat Power Support Systems according to the FAA, before any conversion losses in your power adapter; the actual amount available to you may be much less.
