Review: Perfect for what I needed - Not sure if the reviews are lumped together so just to specify, this is for the BE-550G. I have historically never bothered to run a UPS, but I've been having minor power flickers in my house lately, a couple times a week that would reset my computer much to my annoyance (I run my desktop 24/7). I thought I should get a slightly bigger UPS since I have a custom built budget gaming rig, but I did some quick finger math and decided this one would work "for now". The device came with about a 95% charge if I remember correctly. I plugged in my computer and one monitor to the battery side and let it charge up to 100%, then gave it an extra hour or so. It claimed something like 150 minutes of runtime in the APC monitor program so I decided it needed a calibration. I set it all up for a worst case scenario simulation -- I used MSI Kombustor to load up the CPU and GPU and then pulled the plug. I wasn't 100% sure I'd picked one with enough wattage but it didn't flinch. It did however tell me I had 1 minute before shutdown (set to shutdown when 5 minutes remained). So I quickly set the computer back to idle and the runtime jumped back up to 7 minutes. I let it run to shutdown and everything worked just as it should. However one of the safety features caught me off guard. Forgive me for not looking up the specifics right now, but basically wait a couple minutes after power is restored if you drain the unit until it shuts down. If my memory serves, the safety feature will shut down the battery for 2 minutes (or maybe one?) after power is restored after a full drain then cycle the power. So being "that guy" who doesn't like to read directions, when it died I plugged it back up and hit the power button on my computer... It booted most of the way up then there was some beeping (from the UPS) as it cycled the power and my computer reset, and about the time it got back to the BIOS screen it cycled the power again with some more beeping. The more you know. It can't possibly be good to fully discharge a battery in 7 minutes or less, but this thing functioned flawlessly and could be a life saver. It didn't even heat up that I could tell. After my "calibration", the monitor program now says I should have 15 minutes at idle, which is probably pretty close to accurate and more than I should ever need. The next day after I hooked it up the power dropped out for a couple seconds during a storm, the UPS kicked on just like it should, and reported the problem to me in the monitor program. Now I'm just wondering why I didn't buy one of these sooner! Note that this thing takes forever to charge itself (think 12+ hours from 20% which was the magical 5 minute cut off on my system), probably to avoid unnecessary lead-acid battery related risks on your carpeted floor, but that shouldn't be an issue unless you're having constant power problems. Just a note for anyone who (like me) sat around scratching their heads about which UPS will do what you need, maybe this will help... I already told you the estimated runtimes I got, here's a rundown of the power consumers on my rig: CPU - AMD FX-4350 @ 4.2ghz GPU - MSI NVIDIA GTX-760 Gaming Storage - 2x WD Red HDDs, 1x Samsung 840 EVO SSD Monitor - Asus 23.5" 1080p Update 10/16/2016: This unit is still doing its job without a complaint. The PowerChute program tells me that the unit has switched on twice for "blackouts" totaling 9 seconds and twice for "electrical noise" totaling 24 seconds, in the past 24 weeks. It doesn't seem to register extremely short-lived problems (a second or so), I say that because on a couple occasions I've seen the house lights flicker and heard the unit rapidly click on and off with no report. No big deal. Also the Estimated Battery Time has gone back up to 145 minutes, I haven't bothered to recalibrate because I never really look at it anyway and I know what it'll do. It periodically reports that it passed a self test, which is nice although I'm not exactly sure how it performs that test.
Review: Must have in severe weather areas - After having two routers that fried themselves during power failure events, I decided it was time to protect my new router and it's modem with an uninterruptable power supply. The APC 550 unit is fairly large and heavy, but it does its job well. With a power capacity of 330 watts, I placed the modem and router on two of the four backup outlets. They account for 25 wants of usage, meaning I get a little over 2 hours of backup run time for those devices. In one of the surge-only outlets, I plugged in my large screen TV which draws 215 watts. This gives the unit some spare capacity so I don't need to worry about overload. One important thing to note is that while the outlets are generously spaced, my router and modem both have longitudinal power bricks which means only those two devices have room to fit on the backup power outlets. To set up the router you need to at least temporarily connect the APC unit via the supplied USB A cable to a desktop or laptop computer running Windows or Linux. Then you download software from the APC website which allows you to tell the APC how it should respond during power outages. (e.g. keep devices running until the battery is depleted, or shut devices down after a set period of time or battery usage) and allows disabling of the audible alert. The alert is a loud beep and very annoying. The software also allows you to check on the battery health. Once the setup is done, the APC no longer requires a computer connection. As other reviewers noted, the attached computer must be running either Windows or Linux. The software is not compatible with MAC or Android. To me there are two major benefits to having a backup power supply to keep your home internet access up and running in a power failure. First, you protect your devices from being fried from a power surge when the power comes back on or it flickers on and off multiple times during a storm. Second, and this is critical if you live on an area subject to severe weather, it allows you to monitor weather radar and alerts on your laptop or tablet device while the power is out. If you're under a tornado warning, that's when you really need continuous internet access to watch the storm. APC units are made by Euopean Schneider Electric and manufactured in The Philippines and enjoy the highest ratings on desertcart. Almost all the other ups units available are made in China and seem to have rather large percentage of one-star ratings.

## Questions & Answers

**Q: How long will this UPS power my system when the power goes out?**
A: Runtimes of any UPS will vary based on the amount of power required by your connected devices.

**Q: Will the UPS automatically switch off from the battery backup when power is restored?**
A: Yes, when adequate power is restored to the UPS and is within the operating voltage range of the UPS, it will revert to passing utility power to connected electronics.

**Q: My UPS is on, but my power button is blinking and beeping.**
A: The battery needs to be connected first. Please read the user manual for instructions on connecting the battery.

**Q: Can I plug the UPS into an extension cord, or does it have to be plugged into a wall outlet?**
A: To get the best power available, your UPS should be plugged directly into the wall outlet. Plugging your UPS into a surge protector may cause the UPS to go to the battery often when it usually should remain offline.

**Q: Is this UPS battery user-replaceable?**
A: Yes, the UPS is compatible with a dedicated user-replaceable battery, and the APC replacement battery cartridge helps restore UPS performance to the original specifications.
