Well now... I hadn't really considered that there was an inverter in my
laptop.
So if I'm running it off the inverter now, the current would be going from
dc to ac to dc back to ac ??

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.
