[Elecraft] K3 going expeditionary

[Ted Edwards W3TB]

I am planning to put my K3 in the car for the upcoming Tennessee QSO Party
so that I can go rover/expeditionary.

With that comes a question:  Powering from that accessory socket which
appears limited to 15 amps instead of the 20 amps that the K3 wants at full
power, do I understand right that reducing to 50 watts output and taking
the -3dB will work out in terms of power draw?

In the past, I have done QRP and would like to be a bit louder this time.
Thanks to all who might respond.
