Don't know, but let's see. I'll try and find 100 watts of a few things and hook it up to a power strip and plug it in the UPS. It's quite nifty, it says how much watts, volts in and out, the load percantage, hertz, and est. runtime in minutes. It has a battery and capacity bar on the LCD screen. It can be used as a regular plug in just when the electricity stops the fan kicks on and it's in battery mode. It has 4 plug in and 2 surge plug ins and 2 plugins for battery mode. This is where you would plug in your filters or plug in a power strip for your filters or etc.
Just started it up at 3:07pm. It's running at 101 watts right now...close as it gets. Actually since I've been writing this, it's at 117 watts, the emperor 400 must be spinning faster and use up more electricity....who knows. It says it's at 13% load capacity and the estimated run-time is 41 minutes but it's been there since I wrote this at 3:08, so it's just what is says...an estimate. Also be aware that since the watts is up over 100, it would last longer. I'll let you know when it dies.
Also it has the original box and other crap that came with it.
