Another commenter already pointed that out about the word jump, you can reference that comment for my reply. On the second point, I can comfortably pull 50-100 amps for an inverter from those terminals. I believe the DC-DC is 2500W on my car - I have an early model X which is over specified in many regards. It does not take long to charge an ICE battery enough to be able to turn a starter.
