Hard to say for sure, but probably. The problem is you're taking the power source's power, stepping it up to line level's 110-120V, then the Duo's power brick is converting back down to what the Duo uses. You're wasting a lot of power in that conversion.
I've thought about building a battery pack with a small car or motorcycle battery with the Duo's car adapter attached. Wouldn't be quite as portable, but fairly cheap and I have the parts readily available. Scott Holder -----Original Message----- From: PowerBooks [mailto:[EMAIL PROTECTED]] On Behalf Of [EMAIL PROTECTED] <snip> I plan to use it as a mobile power source in my computer bag for my duos, but I am wondering how long would/should it be able to power a duo laptop? I would ASSUME that it would have to be longer than the 10-15 minutes it can power an entire desktop system... ...right?!? ;-) -- PowerBooks is sponsored by <http://lowendmac.com/> and...
