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 ?

I don't do either. I power the laptop brick with 120 AC from a $30
inverter.
