I'm trying to find out whether a laptop computer can be powered by an adapter via USB cable.Is it possible? Feasible? Available?Thanks!
Some lower-powered devices can be powered by USB. I believe a laptop would draw too much amperage to be powered by USB.
Good question, however I don't think there is a way at this time. I am a Computer Engineer and coming from an electrical point of view it would be very difficult for the USB cable to send enough power to the battery to be able to charge it significantly. You have to understand that the laptop battery is very large and has to be significantly more powerful than a battery like say the iPod that can be charged via USB. Power consumption and load means the world to batteries. A load like a laptop would use on a USB cable would fry the cable in my opinion. Take care, Chad
