Snip.
Finally a DC-DC converter (car adapter) should be used rather than the
laptop's power brick, which will be a source of electrical noise and of
power loss in conversion.

My laptop has a 10.8 v battery, and it calls for 15 v input from the battery
charger.
Would 12 v plus (or better when the engine is running) from my boat charge
this battery sufficiently ?
Or do I need to shell out $80 for a dc charger/transformer ?
