I just got a new external hard drive that wants 12 volts at 1.5 amps. it comes with a wall wart, but I'd rather find some other method to power it to keep it more portable friendly. (only need 1 outlet to power the drive and laptop)
I've got several options, but i don't think most of these work easily...
I've got some open USB ports (i know those have a 5 volt output, so i don't think that works)
firewire (looks like 4 pin, which i don't think supplies power)
esata (i don't think that carries power either)
now the ones that i think may get somewhere...
there's an expresscard slot, ethernet, and phone line port.
as another possibility, the power supply for this laptop outputs 19 volts at 6.32 amps.
any help in a way to build something for this, a place to buy one, or to just say it won't work, or it's just a bad idea, that would be appreciated.
