[QUOTE="Demapples, post: 1392556, member: 199799"] An RV, like a boat on shore power, gets 120V AC from the outside, then inside the vehicle some appliances are 120V AC and some 12V DC (in North America). A [B]converter[/B] converts 120V AC to 12V (or whatever) DC. The boat or RV can get DC from vehicle alternator/batteries or a converter. An [B]inverter[/B] converts DC to AC. At least that's the terminology I've become accustomed to, but I guess technically it can get hairy. A laptop power supply converts 120V AC to ~14V DC. In an RV or boat running on 12-14V DC from alternator/batteries, an inverter converts the 12V DC to 120V AC, then the laptop power supply converter converts 120V AC to 14V DC. Amps = Watts / Volts All this is pretty vital for working out how to power computers on small boats. Another reason to like the iPad (10 watt charger). [/QUOTE]
