    CyberPower - 750VA Battery Back-Up System

    When my eons-old UPS unit's 2nd battery finally gave out, I found out that UPS was obsolete and a replacement battery cost half as much as a brand new UPS. So I took the opportunity to buy the CyberPower 750VA model; it's an upgrade and has worked flawlessly for me. The number of outlets (two of which are widely spaced to accommodate AC power adapters and two USB charging ports. The ability to communicate the status of the UPS to the computer (via the the PowerPanel Personal software) is another plus for this unit.

    More Power than I was expecting

    I have a very tight media access port in my new home, so I needed to find the slimmest UPS within the dimensions to fit into my space. This unit is PERFECT in that regard. I was expecting that by going with a small profile unit, my backup power times would be challenged. Much to my surprise, when I needed it for the first time I discovered that it would keep my vital systems up for 90 minutes. This includes my optical modem, router, switch, a video hub, home automation hub and charging power to my alarm panel. My expectation was to get at least 10 minutes based on the 750 VA ratings and posted reviews. I am very pleased with this unit.

    replaced an old APC battery backup that was about 15 years old with this CyberPower 750VA and it works perfectly. No longer does the thing beep and shutoff every few days. The spacing for the plugs were perfect to fit laptop, printer, router, modem, monitor and Alexa. It's slim and fits perfectly against the wall between my desk. Hopefully this will last me another 15 years like my old one.

    So far so good. Lately we been getting mini surges of power off then right back on. My father in law who did electronic type of work for the local county told me to get these for major equipment like my xbox series x, our computer and camera system as this type of outage is really bad for this type of stuff. Will alrdy we had power surge and we didnt even realize it happened right away as our tv and my xbox never even flickered!! Kept it all on without a hitch. Gave me time to shut it all down and not cause a issue. Never lost wifi signal as it kpt that going as well which is great when all this stuff has to reboot had we not had it protected. These def work! And this size is great for things like mentioned above! Mind you i have one in living room, mancave and my wifes girl cave protecting all important electronics! Father in law says these are a must have and after 40yrs of experinece i dont doubt him!

    Exactly what I wanted for my particular need. I just wanted to plug in my DirecTV Genie to battery backup so that if we have brief power flashes it doesn't have to completely re-start. That way recordings won't be interrupted, etc. Have it sitting behind my TV and it fits perfectly with the narrow profile. Has spacing to allow for a couple large plugs.

    Doesn't get much simpler than this. Great spacing on the outlets. Plenty of battery outlets too. I have this setup for my network switch and Pi DNS. Haven't had power go out yet to test but don't see a d issue.

    It’s a well built safety for our main entertainment circuit. I almost never loose power so I just need protection like this provides. It’s spaghetti wires in my photo, but out of sight out of mind. I have used it for about 1 year now.

      Hello, The SL750U does not have Automatic Voltage Regulation (AVR). I would recommend a UPS with AVR like the CP1000AVRLCD to resolve the issue at hand (voltage sag on circuit). Thank you for submitting your review! CyberPower

    This battery back up is reliable, and easy to setup. I was having issues losing power in one of my outlets and could not get it fixed right away, and this helped to not lose internet (as it's connected to my modem and router). I am willing to bet it will come in handy during a power outage, as well.

    I had my grandson build two computers for his siblings and needed a backup battery to protect from power surges. This unit has delivered thus far. It is large enough to handle three PCs yet still fit on a table where all three systems reside. A very good buy for the money.

    These are great power backup units for a desktop or laptop computer... I’ve used versions of them for over 15 years. What I use them for most is to have LIGHTS when the power goes out! These will power a 60 watt equivalent LED bulb (actually using 9-12 watts) for days! They are great backups for your cable TV and modem as well. And they have two USB ports, so it’s easy to charge your cellphone or IPad when the power is on or off. They also have built in surge protection... cheap insurance for your big screen TV.
