Do you really need more than 2.5 hours of battery power? I can imagine myself playing on the dock in the morning, taking the train and using the battery for 1 hour, working/school, taking the train with the battery for 1 more hour and then dock it back on.
Um, yes? 2.5 hours is terrible. Besides a daily commute, many flights are more than 1 hour. Also, it'd be nice to not have my device die immediately if I forgot to charge it three times a day.
I've flown hundreds of times in my life and never been on a plane which had power or usb sockets. Airbus 320/Boeing 737 don't tend to be equipped with them.
Sorry, but that's just impossible, really. Any sufficiently long flight, especially international, ALWAYS has power connectors and/or USB slots. Admittedly the power plug is often hard to find, hidden under the seat or armrest, but the USB slots are usually right below the heads up screen for movies. Unless you're flying extremely short distances only, power is basically included in all flights at this point. This applies to coach as well.
Ok,let's have a game. Take any European flight with Ryanair, Easyjet or Jet2.com. If you find yourself on a plane with USB or power outlets,I will happily refund your flight in entirety. Like I said,I have flown hundreds of times(20-30 times a year for about 5 years), only with those airlines, all flights were about 2-3 hours long, and not a single one of them had USB/power sockets.
You're definitely not looking hard enough then. Like I said, they are typically hiding somewhere under the seats. There is NO WAY a super common flight like LA to NY does not have power.
I'm on a plane at least once a month with Delta and American Airlines and even small regional jets tend to have USB plugs or power outlets. It may be hidden under the seat or in the arm rest, but what they're saying is true. Most if not all airplanes have power available.
