I agree about being "ultra portable" ...
That's the reason I posted about the car-charger (and emPower) adapters.
If you travel long distances, you do need some adapters.
Long haul flights (and even some domestics) have 3 options ...
"cigarette plug" ... the NTK bullet suffices
"120v" (usually dual for US or UK) ... the stock charger suffices
"emPower" ... the small adaptor + NTK bullet suffices
There is also a potential need for
this when traveling international.
In total all of that kit is MUCH less than the equivalent for a "laptop" (ask me how I know).
Also, you can check a site like seatguru.com to know what you actually might need/want in your carry-on.

If you really want to fully charge the PRIME from your car you will need to buy an inverter and use the PRIME's AC adapter.
Uh, the point about the 12v/2a NTK is you
can fully charge from "cigarette" plug without the bulk of an inverter ...
Also, the 5v adapters won't charge (or maintain?) at all (according to
this thread)

I am only aware of United Airlines that support this charging from a plane.
United + Contenental + Air Canada
may have emPower ports (A320/757/767 typically).
And even then it's hit or miss if they
actually function
