Airline power adapter or cable

[twynne]

As the magsafe adapter will clearly no longer work, has anyone found a solution as yet for powering the new Macbook from an airline seat? Would a cable alone work (ie. USB to USB-C) or is there some adapter that would allow the 29W adapter to be plugged into an airline seat?

Thanks!

From what I read a USB port will not have enough power to charge a rMB. I have a USB-C to USB adapter, but from everything I've read USB charging ports do no output enough power to charge this laptop.

Thanks - that's what I expected. So that suggests the in-seat power is the only option. Has anyone heard of an adapter for airline that provides a USB-C port on the 'device' end?

I've wondered about this. Has anyone tested this, or found exact specifications on the minimum current needed to charge the MB?

Standard USB ports do not have the oomph to charge it, but iPad class USB ports appear to be able to. It may still hit the battery some during use, but it'll be able to charge decently while powered off and at least extend the life while powered on. I've got an A-C cable coming this week and am looking forward to testing whether or not it can maintain power during the day off my iPad charger at the office.

This sounds plausible. It reminds me what happens if you connect an iPad to a lower-power USB outlet: it can charges slowly when the iPad is off, but not if you are using the iPad.
