Reviews around design (5.00 of 5)

  • The compact design does mean larger plugs need an extension cord, but those are cheap and work just fine.------------------
  • this is a replacement of a former buy-so fare it works as designed
  • I like its compact design, clear display and the ability to have it flat or standing.

Reviews around equipment (5.00 of 5)

  • Works amazingly, has already saved my equipment on more then one occasion to allow me to save and shut down without incident
  • I was using this unit to power a small Mac Mini I was using as a server, as well as some networking equipment
  • If you have a fair amount of computer or entertainment equipment and occasionally have power bumps this will protect both the equipment and your data.

Reviews around feature (5.00 of 5)

  • The best feature is by pressing the silver button twice quickly you can shut off the alarm that goes off when the power shuts down
  • I don't think the non-replaceable battery is a dealbreaker for that reason--and surge protectors don't last forever, anyway, so at some point you probably will want to replace the whole thing if that feature is valuable.
  • Best feature over other battery packs I have tried is that you can turn off the alert:

Reviews around outlet (5.00 of 5)

  • Works great, well placed outlets with plenty of room for AC adapters and the like.
  • Thus, I was out of both a UPS and usable outlets until I ordered a replacement

Reviews around surge protection (5.00 of 5)

  • Nice compact UPS, but be aware it only has 3 plugs for UPS backup and the other three are simply surge protection.
  • surge protection side still lets power flow thru, battery side dead 100%
  • Two outlets on the "surge protection" side and two on the "surge + battery protection" side accommodate large power adapters, and an additional two on each side fit regular size plugs

Reviews around size (3.61 of 5)

  • Bought to use with my sewing machine, nice size and and stand up or lay on floor.
  • Small size is perfect and the design/layout is what I wanted
  • Nice compact size, this is perfect for a workstation UPS.
  • its a PITA to find the batteries anywhere (weird size) and they make
  • If you don't get the most expensive, largest size, then you're effectively buying a surge protector that weighs a ton and takes up tons of space and only has four slots

Reviews around power (3.18 of 5)

  • It's a small price to pay for the insurance these things offer against losing your work when the power fails or worse yet a sudden power failure without time to shut it
  • Must have for clean power and long lasting electronics.
  • I have been sitting watching TV and the thing starts beeping for no reason at all without any power loss or interruption
  • It has almost never been used on backup because our power is so reliable here.
  • I keep getting errors that there isn't enough power coming to the battery side.

Reviews around time (1.95 of 5)

  • Maybe next time it will work.
  • This product gave me enough time to manually shut down my firewall device safely and quickly finish a VOIP call because my VOIP box was attached to this UPS as well.
  • My own unit died the first time it was ever needed for backup power, which was within a week of installing it.
  • Contacted support several times and was hung up on or ignored each time immediately after providing receipt showing it was still under warranty.
  • It has screeched in the middle of the night a few times and in the daytime.

Reviews around thing (1.29 of 5)

  • This is the worst thing that I have ever bought from Amazon.
  • With ONLY those two items plugged in, we're on pins and needles as to WHEN this dumb thing is going to overload itself and start its continuous beep (which won't shut off until you reset it, which means you have to shut
  • I was using this to keep our VOIP box and cable modem up during power outages and the whole thing died, not just the battery protection
  • The worst thing is that it will fail on you for no reason.
  • I bought this thing because every now and the power in my house will flicker, causing my computer to turn off and on quickly, which can be bad, especially if I'm in the middle of some work.
