Hi guys,
Am working on a design to use a car battery to power up some equipment (phone, wifi etc). With the limited amps from the cigarette lighter, I was thinking of using a direct cable from the battery to the circuitry. I have attached a simple diagram with my idea and have been toying with the use of zener diodes and even 7812 ic's to do this but am stumped. Really hope that someone can advise.
It looks simple enough but am having a challenge with the fluctuations and insufficient wattage coming out of the lighter head. Thanks in advance!
