FAQ:
Q: Can I use a 12V?
A: Use a 12 volt system when you intend to run appliances directly from batteries. This is a safer voltage for DC circuits as opposed to any higher operating voltages.
Q: What is a 12V power outlet?
A: A 12-volt outlet is any electrical outlet that outputs 12 volts. Cigar lighter receptacle, the most famous example. Molex connector (also has a 5 volt rail), used for connecting hard drives and optical drives, and sometimes for powering flash memory surrogate hard drive modules. Trailer lighting connector, has multiple prongs with 12 volts.
Q: What is a 12V rail, what is it for?
A: For its part, the -12V rail was mainly for the RS-232 serial port, while the -5V rail was for peripherals on the ISA bus, such as sound cards, but it was never really used by anything other than that. and that’s why it disappeared.
Q: What is a 12 volt power adapter?
A: 12 Volt Adapter Power Supply. The 12 Volt Power Adapter, also known as a “Brick”, “Desk Wart” and “Floor” supply, provide a regulated 12 Volts DC output. A 12 Volt Adapter Power Supply is enclosed in a plastic protective case that comes with either an attached AC cord, or a mating socket for one of the 3 common IEC cordsets.
