I've owned or managed at least 30 or 40 of those things (2 at home others at companies where I worked for years) and never ever they emitted anything that was not expected.
Of course they die without further notice, their batteries die...
But in my experience they are safe.
It's a relatively simple device... I fail to see how brands like APC, EATON and others could do this kind of mistake... which would make them illegal in most cases...

Thanks for the great info. This is what I was looking for...various people chiming in who've had a lot of experience with them. I too wondered how it would be a valid product if that sort of thing happened even 1 in 10,000. Thanks again.

One additional piece of advice : test your UPS periodically. I work for a rather large manufacturing company and we have UPS' on probably every system in the factories but no one ever tests them so I am willing to bet a majority are useless. The last service call I had to deal with was because of corrupted files that resulted from a power loss where the UPS immediately died because its batteries were shot.
"They have a consciousness, they have a life, they have a soul! Damn you! Let the rabbits wear glasses! Save our brothers! Can I get an amen?"

Great advice. I was thinking the same thing. I hope I'm not too lazy though -- because it will mean walking all the way down to the basement and flipping the circuit breaker.

I just unplug them from the wall to test them but what ever.

Haha! Yes, you are correct. I dont' have one so I was thinking I had to make sure it had no power by other means. Hahaha. Yeah, just unplug the UPS. I will remember that.

I have an APC Back-UPS PRO 550. This one is 3 years old. I have had many others over the last 20+ years. Mostly from APC. I used to have hard disk drives fail before that. Never since. The main benefit is the clean power. On the occasions when there is a blackout I get a few minutes of runtime. If I am around at the time I shut the system down cleanly before the juice runs out.
I agree with the other reply that said the main hassle is replacing the battery every few years.

I had several APC over the years. As others have stated, the batteries die after several years. Also I find they don't allow for prolonged used without electricity (the ~USD100 ones can give you power for 15 minutes).
What I've been wondering for my own setup here is whether it would be possible to have some battery powered modems and routers: you would avoid useless conversions (your UPS's battery converted to AC 100/240V then converted back to DC around 5 to 12V).

I know. I thought about that too and it is very interesting because you could have a very small battery running the wifi router and cable modem since they both have external adapters that convert to 5 or 12 V.
The challenge is to have the battery kick in when the 120V is lost. I've done some Arduino and electronics stuff so I'd like to look into building something.

Great experience over the years here with EATON - have used APC at work but was never happy with their battery life (I suspect that they ran too hot).
We're in a small hill village with many overhead power lines radiating out over the surrounding area, so whenever there is a storm anywhere nearby brownouts or 1-2 second blackouts are guaranteed.
All the puters, NAS, switches, modem etc. are on "domestic" UPS units (we have 4) and they switch over just fine during brownouts.
My favourite: Eaton Ellipse. Really easy to change the batteries (contrary to some Chinese units).
Note that most domestic UPS use 12v 7Ah sealed lead acid batteries that you can find very easily at £12 to £20 ea. (e.g.Yuasa NP7-12L)
So old that I did my first coding in octal via switches on a DEC PDP 8

I've got:
- A basic CyberPower CP425SLG 425VA just for bench duty (brownout are common where I live)
- The same CyberPower CP1000AVRLCD 1000VA you're looking at for the wife's desktop. (PC and 2 monitors on battery, speakers surge only).
- A CyberPower PR1500SWRM2U 1500VA with 2 critical load (CL) outlets and 4 non-critical load (NCL) for everything else.
Outlet spacing matters. Take a look at Power Splitters/Spiders to get those power "wall warts" away from the back and allow more plugged in.
That "everything else" list grows when you get a UPS. My list:
- (CL) Server for Plex, Minecraft, etc.
- (CL) My desktop development rig
- Power spider with speakers, monitor, & USB hub.
- Power spider with 2 Gigabit switches, Vera Edge, HD dock, and phone base station
- Power spider with cable modem, router, & Vonage adapter
- Power spider with 2 WD EX4100 NAS boxes
I'm sure some would call this overloaded, but I figure the wall warts for most stuff I have plugged in don't draw too much and I tried spreading the load across all the outlets.
With the above setup, I just got 46 minutes run time in a test last week on 8 month old batteries. You do need to change batteries every couple years or so.
Be sure to use the monitoring software that comes with the unit you get.
And don't plug in a laser printer to a UPS. Not sure where I heard that advice from years ago, but I stick with it...

Great info. Thanks for sharing links and models. I will be buying one soon. I was wondering if those smaller units would help with brownouts, because that is what I'm really wanting it for.

I have always had a UPS and never had problems with sparking. The problems I have had are batteries dying after a few years resulting in battery replacement when economical or unit replacement when not, failure to kick in quickly enough form some early APC units and figuring out where to place them and the tangle of power cords.

Thanks for the info. That's what everyone is reporting...no sparks...just battery replacement issues which is normal expectation.

We get many thunderstorms where I live. Power is glitchy even w/o the storms.
I used an APC 1400 SmartUPS for many years.
One thing to make sure you a unit with the capacity to handle the load you have on it.
I replaced the tower machine I used at the time with an HP Z800 with an 1100W power supply. Never gave the size of the APC unit a thought until the Z800 killed the UPS.
Discovered that HP recommends a 2200VA unit for the Z800. I got the APC 2200 SmartUPS unit.
It gets delivered by a tractor trailer on a skid. Unit weighs 110 Lbs. Took two people to lug it up to my ROG. And they typically take a special power cord. Mine required an L5 outlet.
Normally, you'd want that load on a 220V circuit, since the ROG is the 4th bedroom I didn't think it would be too wise to have a 220V circuit in what might at some point (after I am out of the house) revert back and become a child's bedroom.
Even if you aren't using a machine as large as the HP, best to make sure that you match the capacity of the unit to the equipment you are plugging into it. And keep in mind the UPS will likely outlast you computer, so it is probably wise to get a unit larger than your immediate need.

That's a large unit. 
Thanks for the info. I will be getting one I can carry myself.

I have lots of the APC UPSs at my house.
Each time the battery wears out (small battery supplying huge currents) I buy a new UPS right away. Costco has good prices for them.
After I replace the battery in the retired one, it moves to protect some other thing in the house.
There's now also a UPS on the TV+settop box, the router+modem, the expensive computerized sewing machine, the NAS, my wife's computer upstairs, and (most recently) a lamp in the family room.

APC 2200XL for years and never an issue other than changing batteries after 5 years.

Thanks for sharing. that's what others are reporting too...no problems, just battery change.

I have used APC UPSes for many years, on both sides of the Atlantic. Other than needing batteries replaced, I have only had two fail on me - one after almost 11 years of continuous use (it stopped charging the battery), and one after a couple of weeks' use (persistent error indication). I called APC's support up about the latter and, after I described the symptoms, they shipped me a new one out overnight express, with a prepaid shipping label to return the defective one in the same packaging. I did once buy a 'store-brand' UPS, and it died within 18 months. I have no experience with CyberPower. I have also certainly never seen a UPS fail in the exciting way described by the reviewers you quote.
