5.0 out of 5 stars Reliable Backup Power! Great Value in the CyberPower ST425

2026-01-05    -Seth Green

I recently purchased the CyberPower ST425 Standby UPS System, and it's exactly what I needed for protecting my electronics.This compact unit offers 425VA/260W of backup power, which is perfect for keeping my essential devices running during short power outages or preventing data loss from unexpected surges. With 8 outlets, I have plenty of space to plug in my computer, monitor, modem, and other peripherals.The compact size is a major plus – it fits neatly under my desk without taking up much space. The black finish is also sleek and blends in well.Setup was incredibly easy; I just plugged it in and connected my devices. It provides peace of mind knowing that my equipment is protected from power fluctuations and that I'll have a few minutes of backup power to save my work and shut down properly during an outage.For anyone looking for an affordable, reliable, and compact UPS to protect their valuable electronics, the CyberPower ST425 is an excellent choice. It's a great value for the features it provides.

Buen precio

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

5.0 out of 5 stars Real life test was successful. I’ll be getting a couple more!

2026-01-04    -J Schraffenberger

The electricity went out very briefly a moment ago. It’s the first chance I’ve had to see if it does work. And it absolutely does. I have a Mac Mini M4, 6 external desktop drives, and a monitor on the UPS side of the device.When the electricity failed, the unit gave a single beep, alerting me and giving me time to turn on the monitor and begin shutting down. Luckily it all came back on before that was necessary. But it would absolutely would have allowed for that much time.It’s affordable and well made by a solid company! I’m going to get a couple more for another cluster of computers.

Excellent

It arrived on time and in good working order. I plugged it in and waited 8 hours to fully charge the battery. Then I plugged everything I wanted to power with it. When I unplugged it everything I wanted to use the UPS for worked fine and when I downloaded the program to monitor the UPS with my computer it was easy to download and install.

4.0 out of 5 stars CyberPower SL700U: The Little UPS That Catches Power Blips So Your Network Doesn’t Blink

2026-01-29    -Dan Q

The CyberPower SL700U is the kind of UPS you keep around not because it’s a powerhouse, but because it’s a polite, dependable little buffer that smooths out life’s electrical hiccups. It’s slim, unobtrusive, and perfect for the gear that really just needs clean, uninterrupted power long enough to avoid a reboot—modems, routers, ONTs, or those tiny-but-critical devices that absolutely should not experience a brownout. As a surge protector plus brief-runtime UPS, it does its job without fanfare or fuss, and that’s exactly what you want in a unit this size.In day-to-day use, the SL700U behaves like a compact shock absorber. Voltage drops? It catches them. Blips and flickers? It shrugs and gives you the extra seconds you need. Full outages? Well… it’ll keep your small gear running for 10–15 minutes, maybe a bit more if the load is tiny—but this is a UPS you choose for coverage, not marathon endurance. It’s not something you’d use for a full networking rack or anything mission-critical. But for protecting your modem during ISP maintenance, or keeping your router alive while your bigger UPS is rebooting, updating, or being swapped? It’s perfect.Its real value shows up when paired with larger systems. If you’ve got a bigger UPS or portable power station as your primary backbone, this little CyberPower becomes the perfect “inline buffer”—absorbing those moments where the big device switches modes, resets a circuit, or needs a firmware update. Instead of a hard network drop, everything downstream keeps humming along as if nothing happened. For anyone who works with layered power systems or wants belt-and-suspenders protection for the gear that holds everything together, the SL700U fits that niche beautifully.It’s not designed to be an all-purpose safety net, but within its intended role it’s wonderfully reliable. Treat it as the “hiccup protector” for sensitive electronics, especially in modest or home office setups, and it will earn its spot. Just don’t ask it to run a switch stack or an office during a blackout—this is the helpful sidekick, not the hero.Pros• Slim, compact, and easy to place behind desks or network shelves• Ideal for modems, routers, ONTs, and other low-draw devices• Smoothly handles flickers and short drops without reboots• Perfect as a buffer behind larger UPS or power systems• UL certified and generally very reliable for its classCons• Very limited runtime—10–15 minutes max under typical loads• Not suitable for full racks or high-draw equipment• Standby design means it’s not as smooth as line-interactive models• Battery longevity is decent, but not exceptional

Too early to tell how good it works

2026-02-02    -James

Just bought two of these due to their higher ratings and while they seem well made and were easy to set up, it's too early to tell how well they work. One thing I don't like so far is the stupid beep it makes when power goes out. Like I really need that going off in the middle of the night. I don't need to be told, that's why I bought this thing to begin with. The power goes out and my security system and computer are protected. Why do I need to be awakened to be told that?
