APC UPS 1500VA Sine Wave UPS Battery Backup, BR1500MS2 Backup Battery Power Supply, AVR, 10 Outlets, (2) USB Charger Ports

I've used this APC backup unit along with previous versions for years. On older units, I change batteries every 5 years out of maintenance rather than due to failure. I've never experienced any damage to a computer of other attached equipment as a result of line power issues. These units are reliable, safe, and easy to maintain.I did however damage one of my APC unit due to my own fault. I recently bought a new PC and as usual, I attached it to the backup (along with everything else). My new PC alone could consume 1000 watts. Never mind the new giant monitor, the external hard drives, the phones' charger, and a desk lamp. Altogether I was asking the backup rated for 900 watts to keep 1600+ watts of attached equipment going during line power issues. My bad totally. Moral of the story, add up your level of power consumption and get the backup or backups suited for your needs. I should have bought two.

This APC 1500VA UPS is a lifesaver for protecting my PC, modem, and other sensitive electronics. The sine wave output is ideal for high-end computers, and the Automatic Voltage Regulation (AVR) helps stabilize minor power fluctuations without switching to battery.✅ What I love:Clean sine wave output—great for gaming PCs or workstationsPlenty of outlets (10 total), including surge + battery backup2 USB ports for charging phones or accessoriesSolid build quality and a clear LCD screen with useful status infoQuiet operation—no annoying fan noise during normal useI’ve had several power blips since installing it, and my system never skipped a beat. Battery life is enough for safe shutdowns, and I feel much more secure during storms or outages.Highly recommend for anyone who works from home, games, or just wants to protect valuable gear. Solid investment!

This unit has not failed me. Had a 3D printer problems with brown outs. Since I’ve bought this no more weird prints or failures. Note this will only handle up to 4 printers while they are running at the same time. 3 is safe 4 is pushing it.

I have used APC UPS of various models for many, many years. They have always performed as expected. I currently have the Back-UPS Pro BR1500MS2 and it works perfectly. I'm writing this review not so much so about the UPS, but more for information on what to expect if using this UPS with a portable generator. I am an IT Senior Systems Engineer working from home for the last year or so due to Covid. I have a very highend computer system thus the reason I am using the BR1500MS2. My system draws around 450-500 watts constantly and this UPS supports it just fine. Ok, now on to my point. I live in Colorado and if you remember we recently had a very bad wind storm which knocked out power to most of us in central Colorado for several days. After the second day of no power and no heat (house was 39 degrees). I was pretty much forced to obtain a portal generator. This generator was a highend 8650 Watts from a reputable company. Generator performed as expected - Frig is working, got coffee, have some heat - all good. BTW we were without utility power for 8 days. Wife is happy again, so now it is time to get the computer system and network back on up and running. Here is where you need to be AWARE of using a UPS with Generator Power. I plugged the UPS in to the generator power. Turned on the UPS and after a few seconds, the UPS started to cycle from Gen Power to Battery Power back and forth. That's strange, what could be wrong. Well, it wasn't the input voltage from the Generator - Checked it to be 115v continuous, but UPS still cycling. AH HA, it was the input frequency. The UPS is rated as input frequency to be 60 +/- 3hz. The display on the UPS indicated it was receiving 63hz. So apparently, the Generator was outputting just a hair outside the 60 +/- 3hz range of the UPS specs and causing the UPS to cycle into and out of battery mode. Obviously, it was designed to do this. Ok, unplug all of the stuff from the UPS and plug into generator power and all is good. I need to talk with the generator manufacture on getting the output frequency adjusted no doubt. Sorry for all of the blah, blah, but I wanted to set the expectations if you have an operating environment where you must use a UPS with generator power, you may find yourself in a situation where things may not work as expected due to input/output thresholds of your equipment. Oh, and by the way, the generator manufacture said the Gen was operating within their specs 60hz +/- 3hz. Apparently, the UPS or GEN is not exactly within specs.UPDATE for BR1500MS2:I recently had the need again to use the UPS with my generator. Utility folks replacing power pole, so I powered up the generator to keep a few things running. As I had mentioned previously, I was having an issue with the UPS staying online using the generator voltage. After reading some additional detail about the UPS Sensitivity settings, I adjust the setting from the default of Medium to LOW. The definition of LOW is "Use this setting if your battery backup continues to transfer to battery operation frequently on the medium setting. Typically, this occurs when the AC utility source is a generator. Caution, this will allow greater voltage distortions to reach your computer." Ok, so why couldn't the support folks at APC advise me of this. Maybe because of the caution notice - who knows. Anyway, I set the sensitivity to Low, connected the input of the UPS to the generator output voltage. Ah HA, this time the UPS stayed online and stopped the frequent switching on and off line as before. I monitored the UPS output to my computer and only noticed a small variation in voltage and HZ. Not enough to cause any harm to my system. After utility power was restored, generator off, I put the sensitivity setting back to the default Medium. So I just wanted to update my previous entry about using this UPS with home generators. It does work afterall, just change the UPS sensitivity setting.

Nice UPS unit. One minor caveat is APC has discontinued the PowerChute Personal Edition software and replaced it with PowerChute Serial Shutdown. This is more enterprise/server oriented and requires an account just to download it. Thankfully, the old software can still be downloaded and it still works fine, but it won't be receiving any more updates.My desktop is pretty high powered and it's estimating I should get over 30 minutes of run time on battery doing basic stuff like dinking around the Internet. Under load, like playing a demanding game or rendering something in Blender, this drops to 10-15 minutes. This is fine, since it gives me plenty of time to save what I'm doing and shut it down gracefully, or just ride out a small power blip. I live out in the sticks where outages are more frequent than I would like and power quality isn't great, so this gives me peace of mind that my system is protected.

Does exactly what it says it does. The battery was able to carry a TV, PS5 Pro, and Bose soundbar for over 10 minutes while gaming. More than enough to safely shutdown.
