## Description

The APC Back-UPS BE550G is a dependable 550VA/330W UPS battery backup and surge protector designed to help keep essential home and office electronics protected during power outages, voltage fluctuations and damaging power surges. This compact APC UPS features eight NEMA 5-15R outlets: four outlets provide battery backup and surge protection, while four additional outlets provide surge-only protection. Use this uninterruptible power supply as a battery backup for a computer, monitor, Wi-Fi router, modem, networking equipment, gaming console and other valuable electronics. During a power outage, the BE550G supplies temporary battery power to connected equipment, helping you remain connected, save important work and safely shut down your computer. The BE550G computer UPS includes a 340-joule surge energy rating, audible alarms, LED status indicators and data-line surge protection. A USB connection enables compatible computer power-management functionality, while the user-replaceable battery (APCRBC110, sold separately) helps extend the service life of the APC battery backup. Ideal for customers searching for an APC UPS, UPS for a computer, battery backup surge protector, router UPS or battery backup for a Wi-Fi router, the APC BE550G combines reliable power protection with a compact floor- or wall-mountable design for home offices, workstations and network equipment.

Review: Excellent product for home use - This product is just right for providing power to a few small electronic items, like a cable modem, router, and printer. It works well. I tested it by unplugging it from house current, and it worked. The connected devices kept working. This is not a real UPS, but it is fine for home use. A real UPS provides continuous power - it always provides power from the battery. This product does not do that. Instead, it normally gives power from the house current. When the power in the house goes out, this unit cuts over to the battery in a fraction of a second. So it is not continuous power. But it is fine for home use. The change to battery power is so quick that the powered devices do not go down - they stay running normally. I saw one review by someone whose printer stopped during the change from house current to battery. He said that a print job took days to finish. I am guessing that he was using a 3D printer. It is possible that those printers are more sensitive to power fluctuations, and must have a real UPS (see my description above for the difference between this unit and a real UPS). All I can say is - as soon as you install this unit, attach and turn on your connected devices, start printing something, and test this unit by pulling the plug. If any of your connected devices stop working, replace this with a real UPS (for a much higher price). I would recommend this for any home user, to power a few small items. I did not rate any of the features - WiFi signal, tech support, and sleep mode. I did not use tech support, and the WiFi and sleep mode features do not make any sense.
Review: GREAT BACKUP - ODDLY SPACED OUTLETS - This review is for the APC Back-UPS ES 8 Outlet 550VA 120V. desertcart combines reviews for several different models so I wanted everyone to know exactly which model I am reviewing. This is also important since all of the models differ from one another. This is an excellent backup for the price. I purchased it to keep my modem and router from turning off and rebooting should the power flicker or go out for a short time. This backup does the trick. It has 4 back up ports and 4 standard surge protected ports. You can also hook it up to a PC (I did not). The backup is also very quiet (actually silent). For the price, it is difficult to purchase any thing else with better quality. I think APC's backups are great. For those of you that are considering purchasing this backup however, I would like to point out some things to be aware of. First, the backup is rather large and heavy. You cant exactly stick it behind a dresser. Make sure you have ample room for it. The other thing is that the plugs on the backup are oddly spaced. There are 3 outlets side by side and then 1 further away. If you plug one of those larger square plugs (that come with a modem or router) into one of the outlets that are side by side, it slightly covers one of the other plugs. To clarify what I mean, lets call them outlet 1, outlet 2, outlet 3, and outlet 4. Outlets 1 through 3 are the ones side by side and Outlet 4 is the one further away. Currently, my modem is plugged into outlet 1. Because of the size of the modem's plug, it actually covers a portion of outlet 2 and renders it unusable. So I am left with only outlets 3 and 4 for battery backup uses.There is ample room on the backup so APC could have easily separated the outlets evenly to avoid this problem. Anyways, it doesn't bother me since I didn't need 4 backup outlets, but I thought everyone should be aware. Hope the review helps.

## 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.

### ⭐⭐⭐⭐⭐ EXCELLENT ECONOMICAL UPS FOR COMPUTER AND INTERNET MODEM
*by M***G on May 26, 2016*

I bought this unit, it was not provided to me for review. I live in Florida, we have a lot of lightning and a lot of power outage blinks. I bought one of these for our internet router and one for the computer we use to watch online movies and tv content. No more problems. It was a huge aggravation to have a power blink when watching a Netflix movie, sometimes it would take half an hour for everything to return to good working order. Since installing the UPS, zero problems, we even had power go out and stay out for about 3-minutes, the UPS was beeping but then power came back and our system played through the outage with no problem or loss of sync, perfect! I've owned a lot of UPS by APC, I keep buying them because they keep working well and lasting a long time. I have one of their 1500 watt units to backup the computers and digital audio converters in my recording studio. No problems with any hum or buzz and no problems with drop outs either. I tried a popular competitor to APC three years ago, I was using that UPS on my internet modem in California. That UPS failed completely after 16 months and it had not been called on for any major outages, just a few blinks like down here in Florida. After that experience it was easy to buy these APC models. The software included still does not work with Apple Mac computers but you don't need it. These could not be easier to use, connect the battery, plug what you want to backup into the UPS, plug it in to the wall, you're done, you're protected. Great product!
