One guy got a video of his burning up on his Ring doorbell as he rushed it outside: https://i.imgur.com/EzalwYC.mp4
Tear down: https://youtu.be/9gqBzLNMFe4
I have contacted CyberPower for more information.
After I read the Reddit post and watched the tear-down video, I disconnected and opened it up and found that not only did it have the yellow glue, but patches of it had turned brown and had what looked like drops on it in places.
Now I am looking for a replacement, but from the comments here it sounds like other manufacturers have the same issue.
"Thank you for contacting CyberPower Technical Support.
We are aware of the video and we totally understand and appreciate that you brought it to our attention to confirm this.
The person who posted the video offered no evidences to support his claims in the video as he only used assumptions.
There were no presentation of test results or industry data provided to prove his claim. CyberPower products are UL listed for safety and the rubber glue we use is also UL listed. Finally, CyberPower has thoroughly tested the rubber glue we use, and our results are aligned with industry information meaning there is no danger of the UPS catching any unfortunate events or shorting out as a result of the glue. The results debunk the claims being made in the video.
I hope I have shed a light about this concern. Rest assured that all our products are safe.
Regards, Technical Support CyberPower Systems Inc."
I've have numerous later model UPS's made by APC that have gone up in smoke when they were needed most or just up and die for no good reason. The units I have now are supposed to let me know when the batteries need to be changed, but that feature is a total failure.
In summary, all modern UPS's are junk.
A forum member on that RedFlagDeals.com post says that they've seen the same epoxy compound on various electronic items from 1970s, 80s, 90s.
Small APC units are pretty crappy by my own experience as well, especially if you go below 700VA.
I've used several 1000VA back-ups, smart-ups, and while the build quality is generally ok, the trip time for triggering and voltage upregulation was next to useless (passing >500ms). Many back-ups units tend to trigger the differential. The batteries you get from APC itself are just plainly overpriced.
I generally prefer to have many smaller upses nowdays, so I went with a few back-ups rs 500 and two cyberpower (cp900epfclcd).
Upregulation of the rs500 is a joke that you cannot rely on. The output quality is "passable" at best. It's also a pretty basic plastic case, pretty much like the cyberpower. When powered off, it keeps on flipping the main input relay every 10 seconds until it's fully disconnected from the mains.
On the other hand I didn't own cyberpower units for 10+ years like I did for APC, so I cannot truly comment on that.
Can somebody recommend alternatives that truly perform their duty?
I have no idea about this company, but they were definiately part of the collateral damage of me being highly suspect of any thing on Amazon that is from a brand name I am not personally familiar. I don't know if that says more about me, Amazon, or CyberPower.
After two weeks I measured the amount of VOC in the room for a couple of hours and there was still some presence but nothing to worry about.
Overall the unit works as intended ...
At least this is a cause I can pre-emptively fix ony own, I guess.
step 1: exploratory surgery of UPS
step 2: finally install new smoke detectors
The real bummer it's that I got 20kw of batteries a few months ago but they don't kick in quick enough compared to ups, so need keep on using ups
I have also wondered how many reviews people are getting counterfiets. It's hard to tell anymore.
My solution is to just inspect the unit every once a year to see if any yellow glue is turning brown just like in the video. Meh ...
Edit: A closer look showed that some parts of the glue already turned brown. It seems to be affected by heat because the parts that are brown are the parts making direct contact with the board/components.
I have a UPS connected to a NAS and because it is non critical I shutdown after 1 minute of lost power, and I think it can turn back on automatically when power is restored. I only care about data integrity, not uptime.
Guess it’s a good thing I switched to Tripplite.
Be sure to install extra smoke detector around your PC area.
