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

Gives surge protection and battery back up for the numerous times we lose power or get power flickers here. Also lightning stikes are plentiful. saved my computer and modem several times. Gives enough battery back up to get units off line before disaster strikes. Have lost numerous files and Apps before installing this back up unit.




My previous battery lasted 5 years. Securely packaged with thick foam. Hot swappable.

Solid build quality East to rack mount Outlets are spaced enough so that no outlet is wasted Front+Back outlets are a nice feature Very long heavy duty power cord

Nice Design, extra Long Cord if required.


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.

Simple battery connection and change out, no need to use screws and dis assemble the unit like other brands. I have had these ware out over many many years but they still last the longest and easy to swap out old batteries is a must for me.


- 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

AMP meter - let's you know the power you're pulling... Plenty of plugs. LONG, heavy duty power cable.


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.

The software provides good, very complete information, I like the detailed performance info and good event logs, so you know at all times what is going on. Strong native Linux support, great run time. This is the UPS to live by.
