I sure wish I had money now

NIce deal

 

[FlippyBoy]

awesome deal!! thanks!

 

[grifterspawn]

Tempting....

 

[rondeemc]

Very good, and shipping is reasonable also at $3.95. To bad there is tax in TX

 

[Ziptar]

Would this be good to use as a backup for a Fish Tank Pump ????

 

[Ionizer]

Damn this is a good deal, but god, I hate hate hate waiting for rebates.....

decisions decisions decisions, hmm what to do...

I have gotten so many ups's from these hot deals, I have them on all my TV's, and a few desk lamps. When the electricity goes out here, I don't even notice it, except the beeping I left on the one for my PC.

So YES, I say, Use if for a fishtank!

 

[kof]

Good Deal, at just the right time.

 

[mrCide]

FYI ground shipping was $7.25 after actually going to checkout..

Does anyone know if this one shuts the computer down for you in the event of a power surge?

<< ...along with file saving safe shutdown software. >>

While on the topic of UPSs, has anyone hooked smaller UPSs up in series (plug each one into its neighbor and the last into the computer) to make them add up to a larger effective one? I haven't tried this but it seems like it might work.

 

[geekender]

Also, just a tidbit, but if you are installing Windows 2000.......be sure you are not plugged into a mission critical UPS. During plug-n-play detection, it will power off your UPS. Not saying this has ever happened (arrgghhh!).....just warning that's all.

That's series, but not really. It's more like a chain. What you are describing would limit your output to the smallest UPS in the chain. What you would have to do is hook them up parallel. All UPS's would have wall current going in, and all the outputs would have to be combined somehow. What I'm not sure of I show you could hook them up without taking them apart. I guess you could rig up some wires and plug one end into an outlet on each UPS. Take the resulting female plug and run a drop cord off of it. The problem with this (IF it works) would be the current being drawn from the one wire may be too much and overload it. Also, I'm not to sure about how the 120 AC current would join together. DC would easily work, but AC I'm not sure of.

Frys has had this deal for like a year now...

You can only daisy chain UPS's to get more time. Powerwise, they are only as powerful as the weakest link. make sure that the weakest one can pull the power that you need if you decide to daisy chain these.

 

[JameyF]

agreed. I might not have been specific about output. I was refering to maximum wattage, not duration. Chaining them up should give you extended time, but won't give you higher ratings (which is what I thought webley was asking).

 

[rectifire]

Webley,

Theoretically yes...your idea will work. However, not with these UPS units.

Cheaper UPS units (like this one that we're talking about) use an approximated sine wave (also called a stepped sine wave). This will run your computer and other electronic equipment, which will not know the difference. However, when power goes out, the second UPS in series with the first UPS will see this approximated sine wave as an unacceptable power source, therefore causing it to go into battery powered mode. This will in turn net you the same running time as if you had only one UPS.

In order for this idea to work, the first UPS in series would have to output a true sine wave. Models that put out a true sine wave are usually the upscale/server class (read "expensive") UPSes (Such as APC's Smart UPS series). In the case of a power outage, the second UPS in series would not be able to tell the difference between line power and power supplied by the batteries on the first UPS. Therefore, after the first UPS ran out of power, then the second one would kick in.

Just in case you're wondering, I have personally tried this scheme and had this experience. If you want to know the difference between a true sine wave and an approximated (stepped) sine wave, please ask in the Highly Technical forum.

Hope this helps!

Doh!
I bought one and sent the rebate in, but Parago says I sent no UPC code (guess they lost it )
I stupidly didn't make a photocopy of this one (yeah, yeah, I know, but I was in a hurry....) - anyone out there have a scan of the UPC they can send me? - Parago said if I provide a photocopy they'll honor the rebate.

Thanks

 

[crosimoto]

Got one, thanks.

Just info:


When you place this order and go to checkout it states that Ground Shipping starts at $3.95 but that is miss leading.. Ground does start at $3.95 for a 1 lb item but that is not the shipping for this product. Mine cost $7.25 to get to Mass. (ground via Airborne Express)
