    Loaded it up so I know it will be good for about 15 minutes. Bought for bumps and surges. Printer, switch, two monitors and a computer. I have had two power bumps already. The lights in the house went off and on but the computer equipment stayed on without even a fade in power. It has paid for itself already. Normally buy APC but so far I am completely satisfied and I saved $10.

    Solid product and price. Works as advertised, got to test it already this winter! Half the spots are battery plus surge protection, the rest only surge protection.

    Does come in handy when power goes out to charge small devices. Must be plugged in tho to ground it. It's not a wireless charger.

    During storms, our power frequently “blips” - going out fo a few seconds at a time. While not generally an issue, this is highly annoying if watching TV as it causes the Roku or other streaming device to entirely reboot, often losing your place in the show. Enter this battery backup. I typically use larger backups (size and voltage) for my computer equipment, but it’s hard to put these in an entertainment center and they aren’t really needed for this type of application. This CyberPower device is the right size to tuck away in a (larger, to be fair) entertainment center and provides enough boost to get through these power blips without any resets. It works, doesn’t get in the way and doesn’t make itself known. Highly recommend.

The additional features like surge protection and automatic voltage regulation add a layer of security for my valuable electronics. I've noticed a significant reduction in the risk of damage due to power surges since using this device. Moreover, the audible alarms and LED indicators are useful, providing real-time notifications about power status and battery levels, keeping me informed at all times. In terms of noise, this battery backup operates quietly, which is a bonus in a home office environment.

    Working well after 2 weeks. Mysterious AP and router crashes in my network cabinet have ceased since installing this. Outlet spacing and orientation works very well for most devices as well.

    Easy to use and setup. Plug it in, wait a few hours, use with your stuff that you really don't want to shut-off unexpectedly. Power outages and surges happen with little or no warning but this will allow you to save and shut down programs to avoid damage or data loss. I have one for both televisions, computers, landline, and internet equipment. Plenty of outlets on the battery back-up to plug in multiple items. Lots of protection and convenience for not a lot of money. Good Value.

    It's a good basic battery backup

    I have only owned this particular UPS for just about a month. It is the third Cyberpower UPS that I have owned but, this is the most basic of the three as it has no LED or LCD screen to tell you about the state of the UPS. However, I only bought this one as a safe-guard for the new TV I bought at the same time as this (in case of power outages and surges to protect the circuitry). Since only half of the inputs are both surge protected and backed up by battery you do want to take care that you are plugging in to the correct side with anything that you feel should have the benefit of having battery backup. As long as this works as it is supposed to when the power goes out I expect it to be of the same quality as the previous two Cyberpower battery backups that I own,

    Solid choice for a surge, protector and backup battery. It doesn't have any fancy bells and whistles, and you cannot use it as a UPS but for the price, it's worth it.

    We bought this to ensure we were prepared for outages during storms However, its kind of like when your car is acting up and you go to mechanic, but it acts like the perfect child. Since the purchase, we have had numerous thunderstorms, but nothing that has knocked the power out. Go figure. At any rate, seems to be a good unit.

    The compact back-up system fits perfectly on my desk behind the monitor as well as providing enough outlets to power the flatbed scanner, laptop large monitor, controller, and WIFI system. I'm hoping the new system works as well as my previous back-up system that ran trouble-free for 28 years. CyberPower made the old and new systems.

    Thought I was prepared with a automatic whole house generator. When the local Power Company. Experienced over 2 weeks of intermittent power failures daily. What you don't think about is that delay of 30 seconds. Between loss of power and generator taking over. That causes hard shutdowns of your system. This system is able to keep my desk top, printer and modem. All powered like nothing ever happened. Till the Generator can kick in so no more hard crashes. $45 upfront is a great investment. Compared to the cost of replacing or repairing sensitive electronics. Plus the built-in surge protection gives a piece of mind.
