Seems like a lot of $ for hardware that won't run a decent size powerhead for very long. For $200 you'll get a good sized inverter . Hook that to a car battery or better yet a deep cycle & you're good for much longer. If you need to buy a battery, of course cost will be more, but you'll have a better setup. The batteries in UPS units like this are cheap & scary.
