Over a period of time a modified sine wave inverter may ruin any battery and/or equipment that uses a transformer less capacitive voltage conversion system.

If you are planning on using an inverter on a full time basis for years to power labtops and other electronic equipment it would be prudent to install a pure sine wave inverter . [/QUOTE]

I need to power a MacBook Pro in my sailing boat.

Is there a way, however, to power the Mac directly from the boat batteries, keeping into account that the boat batteries are around 12.5 V max and the Mac laptop rechargeable battery is (at the moment):

Amperage (mA): -1947 (recharger not connected)
Voltage (mV): 11113

Thank you.
