In Battery Backup (UPS)

Works as advertised. Was able to power my AMD X4 955 w/ CF 5850 and 2 LCD monitors for about 16 minutes. Software is easy to use as well.

I bought a few of these here and there and they worked great when the power went out, machines stayed running.

Easy to set up and install.

easy setup & works fine

Works as expected. keeps my devices running long enough for temporary power outages or for me to shut things down if I need to.

- Works as advertised, supports my mid-range PC with dual monitor setup long enough to save, close my work & shutdown when outages/fluctuations occur - power supplied to my devices plugged in remains consistent & entirely uninterrupted - Has lived through over a dozen power flickers & full on outages in my small town which is notorious for frying household appliances with our terrible power company (in southern Ontario, Canada) - Alarm when wall power is lost and UPS has kicked on can be turned off/on - Alarm, when on, is not excessively loud - the word alarm makes you think it will be screaming at you but it's comparable to a microwave button beep, probably a little bit quieter - When alarm is turned off, it still makes a very audible click when kicking on due to external power being cut off, so unless you have closed headphones or are blasting music you'll probably know the power went out if you didn't have any other indicator (like you had your lights off in your room mid-day or something) and can begin shutting your stuff off

Easy to set up Works great

Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it!

I have had this unit in service since January 2014 and had to replace the battery today July 2020, have not had any issues with it the entire time. Very easy to swap out the battery when time comes, just turn unit upside down, remove cover, grab two tabs and pull up, new one just drops in, unlike others that have to fight to get battery clips off of then work to get it out, from time I opened new battery and swapped around about 2 minutes total time, putting another unit on shopping list to replace smaller units

I work in music recording/mixing studio environments and am extremely fussy about equipment that generates noise. I'm pleased to say that after several months of continuous use, this Li-Ion APC rack unit met and possibly exceeded expectations. When in ideal conditions, the unit is literally silent. No fan noise, no hum, no buzz. The only time noise has been observed is either when the unit is charging (due to a power failure) where very minimal self-noise is inevitable, or in an under-voltage condition (117V or under) where the internal circuitry activates in order to boost the output voltage. In comparison to APC's own legacy units (ie: 2U 750VA-1500VA lead acid monsters) which I have been using for over 15 years - they had frequent noticeable cooling fan noise, and could produce undesirable self-noise when approaching maximum load. And anecdotally, I have had one or two units fail over the years and drop the load.

Small and works great for the modem and router and other small power use.

- Compact - Lightweight - Not expensive. I bought mine on sale at Newegg.ca for $49.99CDN. - I bought one of these to put on a narrow shelf in the laundry room to provide UPS to network switches. It's worked out great as I now have UPS coverage for the entire household's network backbone (all main switches are protected by UPSes).

My+ old one died same modlue have had good service

Well packed manufacturer packaging. Very clear multi-lingual user manual that is well worth the time reading the few pages in your chosen language. Very clear warning markers attached to UPS. Very difficult to install and use this unit without seeing the warning marker to connect the internal batteries. Silent operation; it does not have any fans on/in it that I can tell. Novel "master slave" outlet pairing. Lose power to the "master" device and the "slave" device turns off immediately. The manual tells me this feature is disabled by default, but read the user manual carefully to fully understand it's operation.

Keeps lower power electronics running for a long time when the power goes out. (Like wi-fi and cable modem -- clutch) Provides uninterrupted, quality electricity to power hungry devices when the lights flicker. Can be made completely silent.

- Works perfect - Quiet

Has built in ethernet to provide status and alerts through APC's cloud. Easy to read and use LCD display Great Mobile interface for use on table or smart phone

Enough power to keep our server and network running for 1 hr
