Amazon Basics UPS Battery Backup & Surge Protector, 800VA/450W, 12 Outlets, Standby Uninterruptible Power Supply, Compact, Black

Reliable UPS for a multi‑device setup — just stay within the watt limit ✔️ Powers multiple devices without issues (micro PCs, router, switch, etc.) ✔️ Accurate battery readings and runtime estimates ✔️ Handles real‑world home lab / network setups well ✔️ 12 outlets with clear surge vs battery labeling ✔️ Good layout and spacing for multiple plugs ✔️ Build quality comparable to CyberPower units ✔️ Good value for the price ⚠️ Must stay under 450W — will cut out if overloaded ⚠️ Larger and heavier than expected for this class I’m using this to power two micro PCs, a switch, a router, a Blink sync module, and a water‑leak monitoring hub, and it’s handled everything without issues. One of the micro PCs monitors the UPS status, and the battery readings and runtime estimates have been consistent and reliable. Battery performance has been solid. Just keep in mind this unit is rated at 450W — if you exceed that, it will cut out, which is expected behavior and not a flaw. Physically, it’s bigger and heavier than I expected, but the layout makes good use of the space. The outlets are clearly labeled between surge‑only and battery‑backup, and having 12 total outlets is more than enough for most home lab or network setups. Build quality feels on par with my CyberPower units. In day‑to‑day use, I wouldn’t be able to tell the difference.

i built a PC and i work from home, staying connected to the internet at all times is very important fore me. more importantly is making sure that my PC stays on and does not randomly shut off at any moment, causing me to lose all unsaved work this product helps protect against that from happening unlike a laptop that has a built in battery, a PC does not, so if your home power goes out, that's it. it's game over. your entire PC shuts down with your power, no running off battery, no nothing however, if you plug your PC into this product, then if your power goes out, you're pretty much safe. at least for 5-10 minutes just today i was working and then randomly the electricity went out in my apartment. all my appliances shut off around me. this doesn't happen often, maybe like once a year. when this did happen, my computer was still running and i was still connected to the internet. everything was shutting off around me, yet i was still able to continue working on my PC as if nothing was happening a couple of minutes go by, and the electricity turns back on. i didn't even notice it was gone because i was so focused on work not only does this keep my PC powered on during outages, my internet stays on too. i didn't lose internet at all, everything was continuing to run smoothly as i've mentioned before though, this power only lasts about 5-10 minutes if you've got a PC plugged in. the PC draws quite a bit of power, so this back up battery can't last much long. but the point of me using this in the first place is so that if power gets interrupted, i have a back up that can bridge the gap. the outages i get last only a couple of minutes. i just need protection during that random abrupt hit, i don't need protection for hours this product has served me well

I bought this back in 2018. I only use it to back up my cable modem and router. It does its job when the power goes out but doesn't last very long any more ... So I decided it was time to breath some life into it. I changed out the battery from a lead acid 12v 9ah battery to a lifeP04 12v 10ah battery. This should (theoretically) more than double the original capacity. We will see how well it works when the power goes out.

I don't usually leave reviews, but this thing has been one of the most frustrating purchases I've made. From day one, it randomly beeps for no apparent reason. The beeping is loud, constant, and incredibly annoying—especially in the middle of the night. Even after checking the manual and troubleshooting, it just keeps doing it. The biggest issue is that it's supposed to protect my equipment during power interruptions, but instead it has shut off my entire system multiple times. What's the point of buying a battery backup if it can't even keep your devices powered? It completely defeats the purpose. I bought this for peace of mind, but all it has given me is headaches, random alarms, and unexpected shutdowns. I have zero confidence leaving my computer connected to it because I never know when it's going to decide to cut power. Save yourself the frustration and spend your money on a more reliable UPS. I absolutely regret buying this one.

Have this connected to my PC/Modem/Printer and the few times it has been needed it has kicked in properly and kept me going.

I just received this UPS, so I can't comment on battery life. I got the 800VA/450W, 12 Outlets. It uses a 12V 9Ah battery that is very common and inexpensive, so when the original battery dies, it should be easy to find a replacement. I love that it has so many outlets, 6 with battery backup and 6 with only surge protection. I have many electronics connected, and this avoids using additional power strips. The main purpose of buying this UPS was to protect my QNAP TS-230 NAS during power outage. This is an entry level two bays file server. I wasn't sure if it would support communication with UPS backup battery. The QNAP manual for this model does not mention anything about connecting to UPS. I received the UPS and charged it overnight before connecting anything to it. It came with a USB A to B cable. The QNAP TS-230 has 3 USB ports: one is USB 2.0 speed and two are USB 3.0 speed. The USB 3.0 are designed for external drives to expand the capacity of the file server, so I figured I should connect the USB cable from the UPS to the USB 2.0 port on the back of QNAP. I turned the UPS on, waited a few seconds for it to come online and plugged the QNAP to one of the battery backup outlets. Next I turned on the QNAP. It takes about 5 minutes to boot. When I heard the second beep that indicates it's ready, I logged in into the QNAP from my computer. After a few seconds, a window appeared that an external device (CPS ABST800) was detected. I clicked on "View external storage settings" and it brought me to Control Panel>External Device>UPS. Here it showed the UPS manufacturer (CPS), the model (ABST800), the battery capacity and the estimated protection time. On this screen you can configure what the QNAP should do in case of power outage. I set it to turn off the NAS after 3 minutes of power outage. Next tested the setup: I unplugged the UPS from the wall. It started beeping every few seconds to indicate that it's running on battery. After 3 minutes on battery power, the NAS started an orderly shutdown process. After a few minutes, it shutdown completely. Perfect! As someone else mentioned, this UPS is manufactured by CyberPower, which is ubiquitous. This is an advantage in my opinion, because more clients are likely to support it than a smaller brand. For anyone that owns a QNAP NAS and is debating whether this UPS will work with it, it probably will.

I've only had this for a few days so far, but everything has been working great and I would certainly recommend it for those with the same use cases. First, I live in the city so power outages in my building are usually very quick, but can cause serious havoc for my local network. I've been debating this purchase for quite some time and finally pulled the trigger after a 4am quick power reset had all of my Phillips Hue bulbs turn on at full brightness. To make matters worse, I needed to wait a few minutes as the modem, router and Hue bridge all reset. This UPS should be more than enough to cover me in these isolated situations. After I received the UPS, it instructs to charge it up for 8 hours before putting it into use. In my experience, trying to turn it on out of the box only resulted in a quick beep but no power light indicator. After letting it charge overnight, it turned right on without an issue. I was able to install the software included in the link on the product page (macOS) and successfully performed a test where the power is cut. Finally, while installing the software I noticed that it was produced by CyberPower. When I purchased this I assumed it would not work with my Synology NAS, but the software gave me hope. After I plugged in the USB cable from the UPS to the NAS, I was very happy to realize that the NAS picked it right up and allowed me to easily configure graceful power down options! The device information also led me to believe that this UPS is actually manufactured by CyberPower, which is probably why their software works with it and why my NAS was very easily able to interface with it. Keep in mind I purchased the 800VA version and I believe the smallest does not feature a USB data port. Additionally, it seems like the 800VA version is heavily discounted for prime members ($25.05 saved at the time of this writing) so it was only $5 more than the middle option which was not being discounted. It is worth noting that the 800VA version that I purchased was rated at 8100 seconds by my NAS as the estimated battery time which is about 2.5 hours - sweet! Also, it is worth mentioning that many other reviews claim it will not turn back on fully after depleting its battery, but I have not tested that and it is not a huge feature for me since the power is not out for that long since I live in the city. From my quick research though, it seems like other entry-level UPS' such as APC does not feature that tech either.

Other reviews questioned the state of the battery. This is a lead-acid battery, and they can have their lifetime significantly reduced if they are discharged below 50%. So I checked the charge on the battery as soon as I received the UPS to ensure that it wasn't already discharged. It read over 13V, which is basically a full charge. I also observed that the battery is easily replaced if necessary, and replacements are available from a number of suppliers here on Amazon. I also connected the USB port to my laptop and confirmed that the software shows a full charge, and I did a brief power-fail test to verify that it cut over cleanly and continued running the router, fiber internet connection and NAS device I have connected to it. So, while I can't speak to what others may have received, the one I got works great and shows no signs of battery problems.

Bought this one as an alternative, no high expectation to start! But, I was wrong! For the price, decent build quality, good amount plugs spots, more importantly it does the job. So far we had experienced 2 blackouts, every time this thing kicked in and did its job. It kept my internet modem+wifi+security system alive for long enough for power to be restored. (once lasted 30 min, 2nd time it was 2+ hours). Recommended for the value and piece of mind.

Keeps wifi and computer on while closing files

happy with the device using mainly to protect some entertainment electronics from brown-outs it does what it's supposed to do happy that it survived a winter with no electricity or heat plugged back in and it charged up just fine

Good quality, easy use, works well all the time

Bought for mother as a back up as the phone system goes down if there is a power loss or failure
