Re: Running Laptops on 12v
Most laptops run on 17 to 19 volts, DC. Therefor you need a CONverter to step your 12 volts to their operating voltage.
Go online and look for a "car" adapter (with a cigarette lighter plug) for your brand and model of laptop. They can be had for us$9 and change up to about us$75.00. The expensive one I bought has worked faultlessly for 6 years, but the cheapos do not fit the receptacles well and heat up a bit, though not dangerously, IMO.
Install a couple of quality cigarette lighter receptacles (Blue Sea?) around the boat where you wish to use the laptop and you'll be fine.
Our laptops run between 2.7 and 5.3 amps of 12 volts depending on their battery SOC and their power settings.
