APCUPS 750VA Line Interactive UPS Battery Backup, BVK750M2 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 works well and is a good product. I highly recommend the APC UPS 1200VA Line Interactive UPS Battery Backup, BVK1200M2 Backup Battery with AVR, ...

If you have a home computer you need something like this. During the last storm I used it to recharge my flashlights while the power was out. I is one of 2 I have in my home. One is on the TV and and cable box the other is in the computer room. I have been able to watch TV for about 1 hour on backup battery when needed. Most of the time power outages don't last that long.

Easy set up, software works, backup works. Good deal. Would have rated an 5, if it had two more outlets.

It works great and looks great. My area is prone to temporary power outages, so I needed something to bridge the gap and keep my computer(s) from shutting down improperly. The APC UPS fills the bill nicely. I would recommend this to anyone needing a UPC.

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.
