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.

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.

For years, I always bought a name brand (3 letters and starts with the letter A). In the past few years, I have experienced a 100% failure rate. Before I retired, I was responsible for buying computers, displays, battery backups etc. for the county we lived in. I always bought the name brand and seldom had a problem. Here at home, I also bought the name brand but in the past 2 years, every backup failed, not the battery, but the electronics within the backup. I switched to CyberPower a few years ago. The 4 CyberPower backups I have are working great and I've not had a single failure.

This is the second CyberPower ST625U Standby UPS System I have owned. Got it again because the first one worked well for 10 years. The surge protection seems to work as I have had no issues as thunderstorms are near daily in summer. When the power does go out, it takes a brief but noticeable moment to kick in. The PC will stay on but the monitors will flicker when power switches over to batter backup. For my set up, a gaming PC with 2 monitors and backlit keyboard, it will last about 2 minutes. Gives enough time to power down but not to keep working. Did have one occurrence where monitors flickered and stayed on but PC turned off when power went out, not sure why but may have taken too long for battery power to kick in to keep PC running. PC is fine so surge protector worked and may have been what cut the power, versus switching to battery, to protect the PC. Decent Surge Protector/UPS for the money but there are better more expensive options.

Fais exactement ce donc je m’attendais du produit. Ca fait le travail requis. Semble etre un produit de qualité. Les instructions fournies sont claires et sans fautes d’orthographe.

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

So far, so good. Easy to set up (did not bother connecting the USB cable) and all seems good so far without any power outages. Outlets well-spaced. Some are surge protected and the other side surge protected and backup battery.

PC with Intel 8700, gaming video card, 4K 40" monitor, ethernet hub, voip phone, 2nd wifi router, all behind this UPS. We're getting the occasional power blip. Sometimes a second, a few seconds, sometimes longer. The shorter blips totally keeps everything going. The longer power outages, I can comfortably use the PC and 4K monitor for a bunch of minutes. How long I'm actually not quite sure. The whole point is that my PC is shielded from noise on the power line and to not have to reboot during a power blip. With a longer outage I have enough time to shut everything down gracefully. So yes, it's winner.

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.
