Keeping fuel fresh for a generator can be a hassle vs. a good UPS... especially since fuel goes bad here within just 2 months of purchase.
The UPS you asked about has "AGM" batteries, which intrigued me. AGM = Absorbed Glass Mats = the battery has AGM separators between the plates => a more rugged long lasting battery. Some companies' AGM batteries are warranteed for 10 years of deep-cycle service. This means 2X - 3X longer battery life compared to typical UPS (gel) batteries that last only 3-5 years.
If the AGM batteries in the UPS you propose are high quality and last 10 years, it would save you the 2 or 3 battery replacements ($120 each time?) that you could have with normal UPS batteries.
This makes we want to hear more about Duracell UPS's. (Later edit: A number of Amazon customer reviews on this UPS are not favorable.)
Finally, since your desired power amperage usage is low, but you want that power for available for hours, the A-h rating of the UPS batteries is your main concern. More Amp-hours is what will give you power for longer periods of outages, while the 1800W only describes how many devices you can run for a short time. Watts/amps are like flow rates of water ( gal per hour) as how fast you can pump it out, while Amp-hour (Ah) ratings describe how big a water supply tank you have. Big A-h ratings = a really big power reserve "tank". steve - - Read-on MacDuff E-visit at http://yucalandia.com
