Amazon Customer: We have not heard much about the brand name Liebert, and we have previously had excellent experience from their competitor, APC, American Power Conversion.

But we decided to discontinue loyalty to APC after it went from making their UPS in Rhode Island to instead making them in China. Not much we can do about that trend, but it has been accompanied by a drop in quality, both in craftsmanship as well as in battery life.

Liebert, as with APC, has a deep and prolonged history in commercial-grade UPS systems, more so than residential products like this one.

So, we see that Liebert is an established brand name, compared with some of the other obscsure, cheap brands that claim the same power capacity and features. This made it worth the risk of buying one to see how it will do. Tentatively, the unit powered up and took about a half hour to come to full charge & "ready."

The Liebert software is crude and not worth using. You can find and download it from third-party sites without having to create a profile on the Liebert site. APC's software allows a user to control the changeover voltage during summer "brownout" conditions, and there are...

MRMarty: It withstood a ~800w load for 20min straight without blowing up, so I'd say it's pretty good. I didn't feel comfortable going higher than that as my rig averages 600w max, but I'd imagine the 900w max output is pretty close. It did get relatively warm after that test, so I'm not sure if it has active cooling for its components. MFGR may want to add that if it doesn't. More than acceptable for my use, though.

Jason’s strong : Doesn’t last more than 10 minutes battery backup

Quentin Vandermerwe: I ordered the product to replace a failing UPS, but was unable to test the new UPS before the return window closed.

The battery that came with the unit was completely depleted, and the UPS started up with a "bad battery" error code the first time I turned it on. Since I was not able to do a return, I purchased a new battery. The unit functioned for 4 days, at which time it started to display the same error. The new battery was almost completely drained, while the unit was connected to power the whole time.

Dylan: Update: My third unit is now randomly beeping. Garbage. This company should be embarrassed. Threw it away, switched to a different manufacturer. I still can't get over the fact that when the power comes back on these units stay OFF.

First unit died within a few weeks of receipt, showed an E06 code, sent it to the manufacturer for a replacement. The replacement lasted around 8 months before also shutting itself off and showing an E06 code when trying to turn it on. Neither of the units were frequently cycled or in any sort of hostile environment; they were supposed to be improving the resilience of my router. Instead they failed off, so even though there was power at the wall my router was cut off. If statistically you give these things an expected lifetime of 5 years then my case of two dying within a year puts me in the <4% unluckiest owners of this product. Those odds won't be improving because, free replacement or not, I'm done with this company forever. The whole idea of a UPS is to improve uptime; it's an outrage for it to ever make uptime worse than having no UPS at all.

Donald Moogk: I am using the product and it seems to be working ok. When I opened it up, it appeared to have been used. The cord was not tied up as in a new product and the accessories package was a mess. The unit seems to have broken pieces ( like plastic) rolling around inside. Very disappointed in condition of product. Seems used.
