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 ?

Depending on how the inverter in the laptop is designed it may do
nothing because it is below the specified input.

But if you look on eBay you can find OEM and accessory laptop DC-DC
adapters at better prices.
