In Battery Backup (UPS)

This little guy has saved my bum many times. The power in my apartment up at college is very finniky; surging, undervolting and completely going off more often than one would want. It acts both as a UPS and a surge protector. The LCD on it is fantastic; I love seeing how much power is left in the battery and how much my PC is using. The additional software included is great as well!

1u slot and shallow. Works great in my 2 post rack. Since I have purcashed this I have yet to have a power outage.. go figure. Dont use the cd, go directly to the manufactors website and get the latest business edition software. Powerpanel Menu is very easy to use and understand

I'm in IT and have purchased 50-60 of these units in the last 3 years with no problems. No DOA's and non have failed yet. I find that 550VA is great for single workstations like Core2Duo with duel 19" LCD's.

Great build quality. Great warranty/support. Unobtrusive Design. Sufficient power backup for most low power household devices (monitor/TV, small appliances, HTPCs, gaming consoles, NAS/router setups, USB & laptop chargers, etc)

Comes with incredibly well written instructions. Software is fully featured and allows for control, same as the LCD menu.

***An updated after several months of usage, and a change in score to 5 stars as I've learned more about the unit. Buried in the software which is run through your web browser, is a setting to turn down the sensitivity on the incoming voltage which fixes my major con of this unit for me, the unit toggling between ac and battery constantly. *** Very straight forward to setup, the units interface is fairly intuitive to use. Provided me with roughly 30min of power for 2 computers, I7 7700K with a 1080ti, and a I9 10590XE with a 3080, a boat load of SSD drives between them, lots of peripherals and 3 monitors. No blip in the computers performance when switching between battery and ac driven power. Online web interface for real time monitoring of the unit is a nice plus, can send you email reports when issues arise with the unit. Clear instructions to position the unit in it's final resting place before you connect the battery. This style battery shouldn't be moved around once it's connected.

- can shutdown my computer after some time on battery. - Can power my 300W system for ~1H - silent operation - web GUI to monitor the system - installed agent popup a warning when power is lost. - warranty is for 3 years

Easy to use Easy setup Works great

Low cost, nice design, dependable, generous capacity for the cost.

Nice LCD display, good value for the money

Cost Effective and reliable. I really like that the display shows the load and the charge. It displays other power information similar to my Kill-A-Watt P3, so I can see exactly how much it is costing me to run my server.

- 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

Makes no noise Compatible with apcupsd Just Works

Slim, Easy to Read Display

This battery is awesome. I replaced a couple of smaller UPS's with this one in a telco closet.. love the fact that i can just plug this into our comcast business modem and it goes to the net and does it's thing in the cloud. This did come with a 20Amp plug so i had to change it over to the regular straight plug.. but you can get adapters for those.

This thing has severed my glory for years and would recommend it. Being a computer technician, i know what i want and what i need and this device fits multiple uses for various equipment.
