Hi,
I want to run my laptop in my car, i was hoping that it would run
directly off the battery, but it wont.
It wont 'see' any externally connected supply until it goes over 15
volts, so i have to make an adapter of some sort to 'bump' up the 12
volt battery supply, to 15 or so volts. The AC adapter that came with
the laptop gives 20 volts (no load) so i spose i could use anything
that would bump up the feed from my battery to between 15 and nineteen
volts.
It would have to provide about 1.75 A normal running, but with peripherals added on it could demand a little over three Amps.
