Re: [ATM] UPDATED need recos for a 12vdc power supply like the vectorjumpstart system

My suspicion is that the laptop doesn't draw anywhere near that
much power most of the time.

> Wow............. am I reading the power requirements of my
laptop incorrectly? it has a 9 cell lithium ion battery that last
for 4 hours of constant use (emailing, working with documents -
it only makes it for 3 hours watching videos). I can run my
laptop off of the battery in my van all night long and the van
still starts fine in the morning...........
