When I turn on the vaccum which is powered even on another outlet my 3D printer still being restarted! what's the point to use this UPS?
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!

Was looking for a compact UPS system that could fit in a residential smart panel that only has narrow space to accommodate devices that could power mini pc, modems, vlan switch and other devices in a reliable way.
I'm so glad I found this option at a fraction of the price of other compact units costing $100's.
Thanks to the battery backup feature, have not had a network loss even though we have had the occasional grid power loss in our community.

We occasionally have a power blip which takes down everything for a short period of time. I decided to pick up a UPS to help get through this periods without having my desktop and internet go down for these short outages. So I picked up the CyberPower to help with that. It's nice and thin, the power ports are easily accessible and I am able to easily run my desktop, monitors and internet router off of the device. We had one power blip happen shortly after setting this up and it worked flawlessly. Super happy with the result and the price.

This back-up & surge protection unit provides a great value. It offers substantial protection, numerous plugs, and a great price - all from a trustworthy manufacturer. The added benefit is that the unit comes in a compact form.

This is a great battery back-up system. It was easy to set up. Two days after I hooked it up, we had a power interruption, and it did exactly as advertized. I am comforted to know that my components are protected.

I live in an area that can experience power outages during hurricane season each year.
I use this for a backup to my 3d printer. It stops any short interruptions in power from ruining a super long print. It's saved many multi-day prints in the past, and it has continued to work perfectly! I also have my snake terrarium and a few other things plugged into it. Super happy with this. It's also a nice slim unit and slips behind everything so it's out of sight.

I got this because the new area I live in has been losing power more recently with the storms. I use my computer for work, school and gaming and it’s so far been working well. I’ve overloaded it a couple times because my pc runs a lot of power usage so it’ll beep really loudly when that happens.

I got this battery back-up for my new home-built PC. I was very scared when choosing this product because of my investment in my new PC. This worked well for several months with no issues. Just recently, I forgot that I had left my PC in Sleep mode when we lost power in the middle of the night. I was woken up by the back-up battery's loud beeping, even though I was asleep down the hall. I was able to safely save my work and turn off my computer. I would definitely recommend this system. I also love it's slim profile compared to other systems.

This UPC performs as expected. Good value for the price. Nice design. Enough outlets for my home office. I only deducted a star due to the unit not having a mute button for the power goes out (didn't think to check before buying) and no info on software to monitor (but customer service was quick and friendly to resolve).

I like this back up system for my router and miscellaneous internet connection equipment. It has plenty of well spaced plug in spots and the USB ports power those things that will run on 5 volts no more wall warts taking up space. I like that it sits vertically because it takes up less space against the wall. All in all it is a good design and works well.

Ok, so here is the real deal: This system battery is solid for the minimum 3 years the package states and there is no indicator light that pops on when the designated back-up outlets (about 4 only) The rest are GFI protected and you can actually test them with a tester from Home Depot to make sure they work. My back up outlets actually worked for about 4 1/2 years, I know this because we frequently have brown-outs. I do recommend this because it does work for the time stated and the price (especially if it's on sale) is the best in town.

My ancient APC UPS finally bit the dust and needed replacing. Fortunately, my local Best Buy had a few left on the shelf. This is a bit larger than the one it replaced, which is great.
It protects my computer and Internet router and gives them more run time during a power outage. It is a plug and play device. Quick and easy to plug into the wall and plug power cords into it. that quick and I am up and running again.
The power glitched once since I installed it. Internet and my computer kept running without even a flicker. CyberPower has a great warranty as well. I am very pleased with this one.

I like the design and specs for the price. Slimmer design than previous Back Up, it fit better in the space. Internal battery is not replaceable by owner, if you that type of Back Up, have more space and be prepared to spend more. This should last several years, so replacing it then will still cost less in the long run.

My old battery back-up did not fit in the space provided. This one is slim and has the outlets turned to the side allowing it to fit nicely out of sight. No loss of my internet/wifi during several power outages. This is my 4th CyberPower over ~ 15 years, and all have been excellent.

Great battery backup system that has kept my devices running during brief power outages. The system is pretty lightweight compared to other battery backup systems I've owned. The spacing for the plugs is perfect, even larger plugs will fit next to each other. Easy to install, haven't had any issues.

This ups has a great design, takes up minimal space with its horizontal type design. Has worked great so far. It replaced another brand that mysteriously would alarm and cut power to everything plugged in even though there was no external power loss to it.

I needed something to replace an old UPS and this was the right price and the right size. I like having the plugs on the top instead of on the back. So far it has worked great.

I selected this item because it gave a reasonable amount of battery backup while keeping a small profile. I was looking for something to fit behind a couch and liked the vertical design this model.
