converting a Power PadTheoretically, it should work. The two issues are whether the voltage coming out of the power pad is adequate and making sure the connections are wired up properly. That shouldn't be too difficult as its DC, its either + or -. But you could get some nasty effects if you get it wrong. The Tech manuals for the DC charger should suffice to explain that. I note the AC/DC converter outpots 20v, which likely means the DC/DC converter also outputs 20v. In that case, you'd need to add a transformer to bump the voltage up to 20v. Have to see the tech manuals to know for sure, though if someone has one of the DC/DC converters, they could simply look at that and it'd be a pretty good indicator. If that's the case, a DC/DC transformer isn't that big of a deal, you should be able to find something if you look in the myriad electrical catalogs. I note that one of those has 160 amphours at 15 volts, though it costs something like $400 or $500. That would give you about twice the time of the internal 888x battery. That's a lot of bucks for the bang. Hang in there though, there is word that fuel cells will be coming out in the next year or so. Your laptop may end up running on a Propane cartridge.
