UPS 950VA Line Interactive UPS Battery Backup, BVK950M2 Backup Battery with AVR, 2 USB Charging Ports (Type C/Type A), Back-UPS Uninterruptible Power Supply

I bought this UPS to go with a mini PC I have. The PC doesn't have a battery. As a test, I unplugged the UPS, and the PC stayed on. I plugged the UPS back in, and the PC kept running as expected. I initially bought a CyberPower CP850PFCLCD 850VA Sinewave UPS. My PC would would turn off when I plugged the PC back in during this test, and it was repeatable. The monitor stayed on, with no visible power cycling. I got a refund on the CyberPower - as the point of a UPS is for your computer to stay on during an outage (!!!). I initially chose the CyberPower for the sine wave, easily replaced battery, and digital display. This is a line interactive step-approximated sine wave system. The manual says the transfer to battery delay on outage is "6ms typical, 10ms max." The manual says the stepped sine wave is appropriate for computers and peripherals and "is not intended for motor driven equipment," and the input power may be rejected (no mention of any associated hazard). This is fine with me. I actually prefer (a lot) the simple operation of this unit compared to the CyberPower. I don't need all those extra settings the CyberPower has, which I realized when I stepped through them at installation. With the APC, you just charge it for 10 hours, and then plug it in and go. The APC is also smaller (6 3/4" tall vs. 9 1/2"). The APC has a voltage sensitivity setting (low/default) for noisy (voltage range) input voltage, for use with equipment not sensitive to this fluctuation, to avoid switch overs to battery, which shortens battery life. I left it on default, and there have been no switch overs. When I unplug the UPS (power outage) there are initial warning beeps, followed by 4 beeps every 30 seconds. You can mute those beeps with a short press of the power button, and you won't get more beeps until the battery level gets critical. The beeps aren't too loud, and I'll probably leave them going during an outage. There is optional software to control the UPS, which I haven't tested and don't need.

This is our 3rd APC battery backup. The first two were used for PC's. This one backs up our house alarm system, wifi router, and cable modem because we have so many short power outages by PG&E. No problems and I expect several years of use before the battery will need to be replaced.

I have used other members of the Back-UPS family. I note that this unit uses a single battery of the same type as other Back-UPS units, albeit in greater quantity. For example, the Back-UPS 1500 uses a pair of these batteries, and the Back-UPS external battery pack contains four such batteries. Installation was straightforward. I plugged in a single computer and monitor. Runtime was initially estimated to be 12 minutes, battery capacity at 40%. I was unable to initiate a self-test from the computer. I then unplugged the UPS, allowing it to run on battery power for 25 seconds, plugged it back in, and was then able to initiate the self-test from the computer. Battery installation date was listed as last March, so I updated the date to today's date, beginning the 3-year service period as of now. The CD shipped with the unit contains a newer version of Power-Chute than I have previously used, and also indicated there are updates available, which I did not install at this time. The battery now indicates 100% charged and a 24 minute estimated runtime. I'm assuming this may change over time as the battery becomes temperature stabilized and properly conditioned. I had bought extra batteries for my other Back-UPS units and am pleased to know they will fit this unit as well.

May 2024: I bought two of these and noticed substantial off-gassing or possibly battery odor at first, and almost returned them, but it subsided within a few weeks. It is my understanding that the country of origin of the battery might be implicated here (when it's India?) but I haven't needed to research that further yet, but follow up with that possibility if you have similar concerns; apparently it is a bit of a known issue. They don't stink now, though. But you might need to let them air out before putting them in a space you'll be in regularly if it bothers you. I'll update this if that issue returns or something else happens. November 2024: These eventually stopped off-gassing after two or three months and have worked flawlessly with a number of issues with power instability including recent storms this month that caused a lot of brief power sags.

Purchased this device to stop having to re-start computer system whenever power flickers. In new area, power supply is not stable, lot's of lightning and 1-2 second power loss. This keeps my computers going, especially with docking station. I have not used Tech Support, so no rating. Relatively inexpensive.

Good value, dependable. All is well so far!

Bought this for my PC, it has a Ryzen 9 7900x and an Nvidia 4080. This is enough power to allow for the pc to be shutdown properly in the event of a power outage. What its really great for is "cleaning" the power that comes into the PC. I'm in an old building with old wiring in a city, the power moves around a bit, every couple of days I'll hear the UPS click off and on, especially in the summer when all the AC's are going. That's not good for the PC so the UPS really helps in that regard as well. Simple setup, wish the cord was a bit longer but that's pretty much my only issues with it. You can get the personal version of the Powechute software to configure it off their website.

Un cadeau de fête bien utile pour mon copain...

amazing product, uing it on my home NAS and modem so we never lose connection to our security feeds during an outage.

These work great. Have installed ~10 in an area that suffers frequent power outages and haven't had any issues.
