I have an APC BACK-UPS PRO 1500VA/900 WATT. before replying to this I unplugged my backup to see how long I could run my desktop computer and the 24 inch TV I'm using for a monitor. It ran for an hour and 15 min down to 14 min left. The time on the backup was going down faster than actual time though, so I don't think it would have lasted another 14 minutes.
