Re: [PLUG] How to figure out my UPS needs

[john@essenz.com]

There's inefficieny losses as you get bigger, but if you buy a big enough 
UPS, you can get several hours. For example, if you buy an APC SmartUPS 
3000, put new batteries in it, it can easily power a cable modem, switch, 
and voip phone for 4+ hours. 

Also, you dont have to go crazy with the $20,000 generator setups for a 
home. 

They sell small 1000W generators (low decibal) that you can wire up to 
your house (if you desire, or just run a cable through a door). Basically, 
you get an outside hookup, and wire it to say 1 or 2 special recepticles 
in the house. When power goes out, go outside, start the generator, 
connect it to the house hookup/disconnect box, and you have 2 indoor 
recepticles ready to go. 

The small 1000W generators go for around $200-$400.

I have this one, I get about 5 hours off 1 gal of gas:
