DC Power, or Direct Current Power, is used to power many of the many pieces of gear aboard, including marine electronics, interior and exterior lighting, winches, windlasses, pumps, washers & dryers, and many more. DC power is typically available in 12-volts or 24-volts, or, on larger vessels, 32-volts. It can be stored in batteries, and converted to AC power when desired using an inverter.
