Great features. Love the battery back up!

Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This plug bar is designed well to accommodate plugs with different widths. The battery back up is extremely valuable during the many power outages we have in SOuth Florida.

I guess it’s working
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The whole point of the unit is to power your electronics and stop a surge. This is all I turn on so if it has worked I don’t know but my stuff still works. So I guess it’s working.

Very good small UPS
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This small UPS does what we need for our powered reclining sofa set. Small enough to fit under without losing the surge protection and battery back up we were seeking.

Good at what it was built for.
||Posted . Owned for 6 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this as a replacement backup for my network equipment. Power doesn't go out often, but when it does, this prevents the router from having to reboot.

Efficient service and perfect price
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.In fact, I was afraid of its cheap price. I don't think it will work well, but by using it, it has been proven to be very effective and the price also very competitive.

Very useful UPS
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Purchased this to use for my tv and fiber modem. While I know this isn’t one of those very large UPS that will run a 65 in big screen tv for a very long time, I wanted it mainly for in the event of a power outage while watching tv, it will give me time to properly shut off my tv. So with recent power outages, I have to say that this thing holds its own in power support. It gave me up to 7 min of run time with my big screen on and the internet modem/router plug in during that outage. I obviously wanted to test how long I had just as a curiosity but that time is more than enough time to shut down my tv properly AND still get about 35 to 45 min if run time in my internet modem/router.

Works as advertised
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Works as advertised. I really hate that you can't permanently turn off the no-power beep. We lose power quite a bit, and once the power goes out, this thing beeps super loud, to the point it interrupts sleep at night. We know the power is out, we can't do anything about the power being out, we don't need this thing beeping super loud to constantly remind us every few seconds. You can turn the bell off, but you have to re-turn it off every time you lose power.

Good for basic applications
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This UPS gave about 12 minutes of run time when i had a 34inch monitor and microATX computer tower with 700W power supply connected to it. I decided to use it for my router only. It estimates to have enough backup power that will run the router for 375-550 minutes.

Awesome Battery
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Got this item on sale. It was well worth it. It even has usb port plugins. It is nice and compactible and not real bulky. You can even pount to the wall instead of having on floor if you want to.
