    A real necessity...

    We have had only a couple of opportunities to use it, but when the lights went out, it was very reassuring to have a working lamp and a way to charge our phones.

    Good Product but No Battery Replacement

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Bought this UPS to replace a malfunctioning one by a different manufacturer. Like the small size and ability to hang on wall. This will provide power to our gateway and one switch. I have purchased over 12 APC UPSes over the years, and have also used other manufacturers. Have always come back to APC. Kicking this one star since this unit does not have a user replaceable battery and there is no mention of this on the Best Buy website, in the information from APC listed on the website, or on the box. It is not until you buy it and get it home and read the manual that you find this out. This is a new version and the older version has a user replaceable battery. Generally, I have had to replace batteries every 3-4 years, so with this unit it is throw it out and buy another one. Usual battery replacement cost is $25, and a new unit is $50 so that is a bummer. If this does not bother you, then it is a good product. I am considering returning it and buying something else.

    Good product, would recommend although Best Buy customer service needs serious revamping, managers require common sense and the ability to think outside the box, created a difficult situation where there was no need

    Good Product But Still on the Fence

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Had bought this model back a few years ago and now the battery stopped working so when a power outage happens it starts to beep that it's not working. I accidentally bought the same brand and model a couple of months ago and still working with no issues. I gave it a 4 out of 5 for right now.

    Nice unit. Outlets are far enough apart to take in account the transformer endings of some plugs.

    Works, but not well

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    works as a battery backup like advertised, but there is no obvious way to see if a power surge has knocked out one of the things. Also, very concerningly, it seems to just start blaring some alarm at a random time with no explanation. Couldn't find any info on it either, and to fix it is just unplug your whole settup.

    Replaceable Battery

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I work from home as an IT professional; wish I had 3 of these a while back during a recent windstorm outage, one for my work PC, router/modem, and switch. I would have had a bit of time to save my work and also the fam could have stayed on the Internet with our wireless battery devices for who knows how long. Easy to set up, has a replaceable battery, and comes with a QC/inspection verification receipt. FYI: 180 joules isn't even close to protecting from a lighting surge BUT it is for other things like possibly an electric company or transformer outage. To truly protect your home from lightning strikes (unless it directly/indirectly hits your home) you'll need something in tandem with this, such as "whole-home protection" tied into your circuit breaker and/or lightning rods, etc.

    Good enough to ensure you can save your work

    Good enough to ensure you can save your work. I had two lap tops plugged in. Unit started beeping after about 20 mins. Beeps every minute after that until the battery completely dies out at about 30 mins. Hover you can mute the beeps. I wouldn’t bank on this to be able to cover you on a power outage to keep your modem and router going for an extensive period of time. If you are looking to cover a desktop in case of power outage to ensure you can save what you are doing, this will suffice. Unit is a bit bulky. Yes it has surge protection and battery but standard surge protectors separate battery pack would take up less space. If this had a longer battery life, I wouldn’t care about the bulkiness, however longevity is under whelming.

      Thank you for taking the time to review our UPS and taking the time to provide feedback about it. The runtime would depend on how much equipment is connected to it. This unit is one of our smallest UPSs as well. We do have larger UPSs if you need the additional runtime. We also have extended run units available in our SmartUPS line as well if you need additional runtime. If you need assistance in choosing an UPS with more runtime please do not hesitate to reach out an APCbySchneider sales member. We offer email and chat services through our support site.

    APC Battery backups are the best

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I have purchased two other of these APC units in the past and they do a marvelous job allowing you a good deal of time to finish and save your work in a blackout. I had one unit battery die on me after two years (battery life is not forever)and the Tech folks quickly issue me an RMA to get a,replacement unit. It arrived in two days and they pay for the returned defective unit. With a 3 year warranty on most of there UPS units you cant go wrong. Im going to Purchase another unit for my son's PC and monitor and printer. I highly recommend this unit.

    This UPS replaced another APC UPS that had died after 6 years due to a battery failure. Best Buy had this one on sale for about the same price as a replacement battery. It seems to be working just fine.

    This product works very well. I was surprised at the number of surges this unit has detected since I connected my computer to it. Had APC UPS for years, love the brand, trust the product. definitely worth the $$, especially with deal of the day price.
