This theme actually begs the question why nobody has made (batteryless) pass-through that uses 12V power as its input. And no, I don't propose sending full 12V (which is typically more like 14 when your engine is running) to your atty. I mean put a simple "buck" regulator in there so you can set whatever voltage you want, from say 3.0 to 8.0. Now how many watts do you wanna vape at? Do the math. A 5 amps at 12 volts would be good for 60 watts, call it 50 after with a safety factory and a bit of loss in the regulator.Maybe a motorcycle battery?![]()
USB pass-throughs exist, but they're a joke. Without a battery to buffer the power, a typical USB port (5V at 500 mA) is only good for 2.5 watts.
There would also be a certain amount of sweet irony in running one's vape directly off a car's lighter socket no?
