Direct from the battery (fused!) is best.
Through a relay if you want to control it somehow (acc, ign or other).
I am powering my touchscreen and my laptop both with universal laptop chargers that have cigarette plugs on the end of them...
what's the best way to power them...
I was plannig running a direct line from the battery in a series circuit...I would rather tap it from my cigarette lighter but I would love input...thanks...
