Re: Low-voltage DC is just USB now
Sounds like the sticking point is the lack of voltage step-up circuitry in the laptop. My car charger peaks at only 12V on the output.
Looking at newer chargers hitting the market, I see a number of sub-60W models that include 20V output, so I wonder if the situation will change. Even if the drain exceeds the draw, it would be useful to have the ability to use lower current chargers in the event of an emergency.
