CyberPower ST625U Standby UPS Battery Backup and Surge Protector | 625VA/360W, 8 Outlets, 2 USB Charging Ports, Compact, UL Certified

The CyberPower ST625U is structurally ideal for placement within an electronics or media enclosure. Because routers, modems, and small switches typically draw low wattage (often under 50W combined), this unit can provide significantly extended runtimes compared to its full-load rating, often keeping a home network alive for 30–60 minutes during an outage. • Enclosure Compatibility: Its slim, 3.2-inch depth and keyhole mounting slots allow it to be mounted vertically against the backboard of a structured wiring cabinet or electronics box, maximizing internal airflow and cable management. • Surge Suppression: Offers 890 Joules of surge suppression and EMI/RFI noise filtration, which is critical for protecting sensitive broadband signals from line noise that can cause packet loss or connection drops. • Management Integration: The HID-compliant USB port allows for direct integration with PowerPanel Personal software, enabling automatic, graceful shutdowns for connected NAS devices or small PCs if the battery reaches a critical level. • Mechanical Integrity: The casing is robust plastic, and the GreenPower UPS design minimizes heat generation, a vital feature for equipment placed inside a closed electronics box. This UPS provides a "painless" way to ensure your internet connection remains stable during power flickers and brownouts, representing "great value" for a dedicated networking backup.

My wifes PC is in our bedroom and shares a circuit with the window AC. Every time it kicks on, it would blip just enough to shut her PC down. Obviously not good for the PC but also makes it unusable. Got this and it solved the issue. You hear it click when the AC kicks on, but the PC runs strong. Not only does it prevent the PC from shutting down, but its protecting it from that little surge of power too. win win.

The computer in our restaurant suddenly tripped when it was turned on, resulting in a blue screen that the computer could not be turned on. Later, when I took it for repair, the Technician told me that the hard disk was damaged. After that, I spent more than $100 to replace the hard disk and install a new window system. Later, several power trips and cyberpower battery backup kept my computer on. Give me time to turn on the tripping power again. This is very helpful.

Overall I really like this product. However let me explain the downfalls. There's really just one. After the battery was fully charged I installed the device to my computer. I connected my computer a 32 inch monitor that's also a television. I also connected a clock radio. So I have three items connected. I installed the PowerPanel Personal software that can be downloaded from the CyberPower website. This software allows you to see everything that is going on with the UPS power backup. Mine shows that I am running approximately 100 Watts in order to power the three devices connected. At full charge capacity it says that it should be able to run 18 minutes if the power goes out. Not bad just enough power to save what I need to and shut down. However I tried it out by unplugging the device. after plugging it back in approximately 40 seconds after unplugging. It said I only had 14 minutes left to run on the batteries. So there is the downfall. There's just not enough battery power to actually use it for a long period of time. But honestly I was not planning on using this except as a safety, in order to power down my computer and save what I needed to. This is an excellent product for that purpose. I edit photos and videos on my computer and this product will give me the time I need in order to save my work if the power goes out. Not to mention to save emails or letters if need be. I only gave this product four stars due to the fact the battery time indicator was not truly accurate. Otherwise I highly recommend this product.

ST625U received 2-25-2020 - I have not had a power outage yet but they happen a lot here in Florida during tropical storm season. EDIT UPDATE ON 10/19/2020 - IMPRESSIVE PERFORMANCE OF ALL THREE OF MY ST625U UPS units when a massive sustained power surge from an underground power cable failure burnt up 5 of my home's stand alone surge protector outlets! My CPAP kept running right through the event while my neighbor's wall wiring burnt up! All 3 of my 625's are still working after giving 40 minutes of stand-by power and their breakers did not blow - END EDIT .... SECOND EDIT 10/2023: all 3 of my units and their batteries are still going strong! I just slept through a short power outage while using CPAP END SECOND EDIT. A slight odor of 'burnt' electronics right out of the box is normal for some electronics product manufacturing methods, do not be concerned with a slight odor that does not get stronger with use. It will diminish. I tested this unit with my powered 5 motor recliner, an LED desk light and laptop running while it was unplugged from the wall 5 minutes. I will definitely update the review if any issue develops (done!). I'm a degreed biomedical technician and this design looks fine for short term outages. This is NOT for CPAP sleeping use, battery is far too small except for short power outages. The isolated battery compartment opens easily with one phillips screw and only has battery wires inside it. I inspected the battery and found 13.2 volt charge after 6 hours plugged in. The charging circuit is extra energy efficient and causes almost no detectable waste heat, an excellent feature, as claimed on the box. After 6 hours there was only one small area of the case that had a barely warm feeling, like human skin. You can triple the run time when the original battery wears out by adding a larger battery that does not fit in the case, like a 17 AH SLA battery. You have to extend the battery wires long enough to let the battery sit next to the UPS. You must have soldering skills and the right tools to do this. The larger battery will not allow use of larger, more power hungry devices but it will greatly increase run time for your existing use during power outages. The larger batteries cost about the same but they are more durable. I have no interest in setting up the software monitoring. Just a gimmick for this size device. The UPS software may not recognize a larger battery capacity but it might if it is based only on voltage remaining. As the instructions say, this will beep when power goes out but you can mute the beeping in advance by tapping the main power button twice. I don't know if it retains the mute setting after a complete battery discharge. You can just locate a battery the same dimensions of the original if you want it to fit in the case. It is 'CPS5.5AH' 6 inches long, 3 3/4 high without terminals, and 2 inches wide. I decided to buy another one of this model for my modem, router and Ooma phone box to prevent those tedious full reboots after a power glitch.

So far ok, no power outages yet

Works with Synology NAS. I have two Synology NAS devices and I connected this via USB to the primary one. I set it up as a USB UPS and it was recognized correctly. I then enabled the Network UPS Server and it was seen by the secondary NAS as well. I couldn't have asked for a more seamless installation. It is showing 100% charged and an estimated 29 minutes of backup time. Physical info for the UPS. It has nice compact size, it has an access panel on the bottom for replacement of the battery, and it has 4 battery backed up ports and 4 surge protected ports. As always, the orientation of the plugs will never be exactly what you want them to be. Search for "Power Brick Extender" and you will get packs of short extension cords. Don't search for "Short Extension Cord" I didn't get as many results. <sigh> I replaced my antique power strip that is probably yellow from overheating with the new backup. I'm ready for Summer Thunderstorms!! Oh, The Amazon Basics UPS is made by CyberPower, however, I got this one because it comes with a 3-YEAR WARRANTY – INCLUDING THE BATTERY; $100,000 Connected Equipment Guarantee, the Amazon Basics does not.

So I have several of these units from a few years ago, but am just now getting around to writing a review on how bad they are; I really don't understand how these are highly rated. I purchased to help protect my NAS as we have frequent, brief power blips at my home. They do absolutely nothing - except throw an alarm - when the power goes out, even for half a second. Using the Powerpanel software, the battery is just fine, the connected wattage is well below the threshold, so why can't these handle normal condition. I have another unit connected to a desktop PC, and it performs the same way). Even when doing a "self-test" with the software, the unit simply shuts off with an alarm, which also means it returns no test results. So, testing it further, got the point of simply plugging a lamp into the unit, and it simply shuts off (with no alarm) but one single light bulb can't even be powered on battery backup. It took me a while to realize how back these were, thinking I just needed to adjust the settings but have been busy with other things and never got around to it until today. Lot's of trial and error - and help from ChatGPT - telling me why this unit sucks. Either that or I got not just one bad unit, but an entire batch of bad units.

This thing has been pretty robust. Does? Its job doesn't complain works as it should. And it's saved a few power outs on our field computers

Compré este no break por temor que el ps5 se me fuera a dañar en un apagon, hasta el momento ha funcionado con normalidad, de acuerdo a las instrucciones hay que cargar la pila por 8 horas y luego de eso, se conectan los equipos de interés, es importante tener en cuenta los watts que consumen los equipos que deseas conectar, por ejemplo el ps5 puede consumir maximo 250, con eso en mente decides cual se ajusta mejor a tus necesidades

1 year update: I cannot say more about how happy I am with the product, It has plenty of Juice and yes honestly in north america you will rarely need a UPS but there are sometimes when it becomes a live saver, No issues with it whatsoever, works like a charm. Has plentny of Usb and 3 prong plugs that work for me. Also has a battery life health indicator that pops up in the taskbar for your PC so you can monitor the UPS health. If I was in the market for a UPS, would I reccomend this for a first time buyer? Yes. Would I buy it again? Yes. Love it. XXXXXXXXXXXX-----------------------------------------------XXXXX----------------------------------XXXXXXXX Overall a very decent buy in comparison to the other products this one is fine with me I use it only for my Computer equipment mainly my desktop and Laptop directly hooked into the Ups and the Ups is connected to a surge protector just being extra careful. But yes I don't regret this buy the price was a bit steep but its competitive to the other products so if you need one in a prime delivery Yes this will do the job I have a gaming Rig and it holds well.

Bon produit, fait le travail. Par j'aurais apprécié la notice d'utilisation en français.

Way back in the day when I used to do my own builds, I bought two huge UPS devices from APC, each weighing at least 45lbs. They never did a thing except beep at me. Both PCs that were connected to them went down whenever the power went out, even for half a second. They were stupidly-expensive units and an absolute disappointment. This month, after a weird surge that nearly bricked my PC (it was not POSTing after a weird stuttering brown-out and I basically gave it a good clean and waited an hour before trying again), I figured it was time to revisit the UPS solution. First and foremost, I was going to avoid APC. Second, I did not want to drop hundreds for a unit where the battery would last a month and then be completely useless. CyberPower's unit took care of the first requirement and well, I have no idea about the second. I'm 100% certain that battery technology and internal chemistry is way better than when I had those APC units so hopefully it will be a long while before I start hearing this thing beep at me to tell me it's useless. That said, within days of setting this up, my house had a short power outage - we get them ALL the time - and my PC stayed up and running with no issues. That's all I wanted. That's all I paid for. I got exactly that and I'm happy. If longevity turns out to be an issue, I'll come back and update this review, but the price point was fair enough and the fact that it passed a trial by fire almost immediately after putting it in place is more than enough for me to give it the ol' thumbs-up.
