Hey everyone, I am looking for a way to deal with some frequent -- and lengthy -- power outages at one of my offices overseas (in the Philippines). The problem is that we are using PCs (not sure about the power supply, Ill have to crack one of them open to check) and we need to make sure that they last at least 4-6 hours after the power has been shut down. The battery backups I see available at retail typically give you 30-45 minutes of backup power and that just isn't enough. Are there any battery backups out there that are reasonably priced that would keep these computers on for 4-5 hours? I need to figure out an alternative to buying a $5,000 gas-powered generator to keep all 12 units online past these power outages (and the internet router too). The computers are used only for office work, so they shouldn't be running full blast or anything, but they will be used to make VoIP calls, Skype, and Microsoft Office.
