Love it. I have 2, and they are indispensable.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.A great UPS at a reasonable price. Protects your TV's, computers, modems, etc. In Florida, think of the times that a lightning strike has caused a momentary power loss, that forces you to do a complete reset. All that is a thing of the past. Pay attention to how and where you are going to put it. Sometimes a smaller flatter UPS with the plugins on the top might be a better choice if it needs to stand behind the furniture.

Great Battery Back Up System
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With the storms that roll through Tampa and frequent power outages, this battery back up is just enough to keep my system running until I can either save and shut down properly, or get to my office to perform the shut down. I have this model on 30+ workstations - highly recommend!

Perfect Function in Lighting Storm & Loss of Power
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Yeah, It does what it is supposed to do. It guarded my computer, and supplied backup power for well over a half an hour. Also attached to it are my scanner, external hard drive, and monitor. This review comes after brief ownership. Very Happy thus far.

Lifetime warrenty, too.

Protect from power glitch
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We purchased these after a short, quick, power glitch took out one of our computers. It was plugged into a power strip, but that wasn't enough for these quick burst. These little guys advertise they will protect us and so far, they have.

Perfect for modem & router
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’m using this to counteract short power outages to maintain a WiFi network in our home. I have our modem, router, and MoCa adapter connected to the battery backup slots. This should be able to maintain internet in the house for at least 30-45 minutes based on the power usage of my devices. I’ll update my review after our first outage, to effectively provide a more accurate finding.

A nice small UPS

No more dropped Zoom calls
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Immediately went on line after the first power blip of summer hit my house and knocked me off an important Zoom call. Delivery to my front door was a surprisingly 1 day and FREE. Easy to set up, plugged in my router and internet doesn't drop!

Good in an emergency
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love it. Keeps everything I need running in the event of an outage. Live in a condo that does not allow generators so we use these to keep the wifi router running and charge phones if needed.

Great Battery Backup - High Price tag
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a high quality battery backup. It worked well during a power outage. I used it to back-up electronic controls for a hospital bed, I had enough power to lower the bed. This unit price was on the high side.

Great product for my need
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought several of these to mitigate issues we have with intermittent electrical "outages" / blips. Even after installing a generator, the power would go down for 10 seconds until the generator kicks in. I put one in my bedroom, powering TV and other devices, another in TV room (powering TV and cable box), and the third in my utility room to power my master cable connection, internet modem, and VOIP phone. These only need to use battery for maximum of 10 seconds before my generator kicks in. While my Google wifi takes a few seconds to reconnect after generator kicks in, everything else runs perfectly. Great solution to my problem.
