1 out of 5 eggsWorking As Designed...who checked??

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: Light, compact for low loads.

Cons: Unit ran ~ 1 year supplying power to a router and 2 modems (~36W), which in my situation is critical because I have VIoP and Web through it. We did have a power outage and my 550VA went dead when I needed! It was the battery but no alarms nor notifications occurred prior to AC outage. So, before buying another one I decided to investigate the units functionality. After few measurements I am convinced that CP's design and validation is very substandard (perhaps on this unit), AND I will not be buying another unit from CyberPower. Here its why:
1. with a known-good battery (12V/5.5Ah) the battery backed AC side of the unit produces 102.7V instead of ~110-115vAC VAC and shorty drops to 97VAC; very unstable.
2. with fully charged battery ~14.2V, main AC removed, and ~36W AC loaded, the unit reports, through the USB software, ~5-7 min of run-time...really????
3. Looking at CyberPower Personal Edition Status with battery disconnected and AC ON,the "Remaining battery Capacity " AND "Battery Status" shows 100% How could that be!!!?? However, this explains why there were no prior alerts from the unit. Removing AC power with bad battery has a predictable effect on the load. I would have attached photos of the set up and readouts but space/tool doesn't allow that .

Other Thoughts: none.

1 out of 5 eggsVery annoying

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: Really works

Cons: It keeps beeping after power comes back on

Other Thoughts: Decided to buy an APC unit to replace this one.

Manufacturer Response:

Thank you for your review on the CP550SLG. CyberPower offers an industry leading 3-Year Warranty on all of our UPS products, which includes the battery. We'd like to talk with you about the set up for your UPS. Please contact us at 877-297-6937 M-F 8-5 CST, or priority1@CPSww.com . The CP550SLG is an entry level UPS with a maximum capacity load of 330 watts - the equivalent of an entry level PC and monitor. It's possible you may have overloaded the unit. If you are connecting anything higher than 255 watts, please consider one of our higher capacity models which will provide greater backup time. Our web site has a "UPS Selector Guide" which will help guide you to the correct models that match your needs - www.cpsww.com.

4 out of 5 eggsGood backup, not for gaming machines.

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: Built very solid. You can even replace the battery in it when it goes bad. Works great with my Synology NAS box.

Cons: Not enough power to handle a gaming machine. I have an i7 gaming PC and its overloading the battery backup. It would work great for a system not doing anything demanding (example: word processing, browsing the web type of computer).

Other Thoughts: Overall I ended up buying a CP1350AVRLCD because it is designed for power demand my computer requires. I did not expect my PC to require so much power, but i someone expected it did.

3 out of 5 eggsNice unit, unfortunate interface

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: The plan was to provide UPS for a little home Linux movie server. It does the job well. My 57 watt draw means 45 minutes of power. The USB interface worked well and the PowerPanel SW worked first time. But trying to configure it...

Cons: So, lets talk about configuring the SW. As, I mentioned I run a Linux machine, which makes me the red headed stepchild of the SW support spectrum. But, hey, you could at least have an English speaker proof read the instructions. It took me two hours of tinkering with the auto emailer to make it work. Then I figured out if it sends an alert, it WILL shut down your system; even if power is restored. The Nigerian Prince writing style for the manual and code comments did not help.

Other Thoughts: The sad thing is, the SW could easily be fixed. Make it so you can run a script BEFORE the shutdown sequence is inevitable (you can delay it, not stop it). Also, is it really that hard to have an English speaking tech editor go through the documentation? The nuances of the English language matter when you are trying to configure it.

1 out of 5 eggstoo Low power

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: . small form factor
. great for devices that don't require consistent power output at 120 volts

Cons: . inconsistent power output as low as 92 volts. (When it should be stable at 110-120)
. at 550VA it doesn't seem to last that long. I have a 22 watt LED monitor and it only stayed on for 5 minutes. Seems to me that it should have lasted much MUCH longer.
. CANNOT be used for a computer that requires consistent power such as my Mac Pro.

Other Thoughts: I have other CyberPower UPS's and they function much better than this unit. I may have gotten a dud but it works to keep a light on in a power outage if its LED.

Manufacturer Response:

Thank you for your review on the CP550SLG. This model is an entry level UPS with a maximum capacity of 330 watts - the equivalent of an entry level PC and monitor. If you are connecting anything higher than 330 watts, such as a "gaming PC", the UPS will be overloaded and will alert you to the overload. We would recommend you consider one of our higher wattage models which will accommodate a higher wattage and provide greater backup time. Also, the CP550SLG is a Standby UPS and does not provide any AVR (Automatic Voltage Regulation) stabilization. Models with AVR will maintain a safe voltage level without switching to battery mode. Newegg and the CyberPower web site (cpsww.com) offer a CyberPower "UPS Selector Guide" which will help guide you to the correct models that match your needs. We recommend the CyberPower CP1500PFCLCD as a great alternative. This model has the AVR stabilization, can handle up to 900 watts capacity and offers pure sine wave - a must for PCs that have an Active PFC Power Supply.

5 out of 5 eggsDeployed 25 without one failure

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: - Reliable
- Provides enough power
- Does not require weird RJ-45 to USB cable, uses standard USB A->B
- Recognized by Windows with no additional drivers or software needed.

Cons: - No user replaceable battery

Other Thoughts: The UPS's we had here in the office were either Tripp-Lite or APC. Some of these were beeping for no reason, despite them being less than a year old. When replacing them with new Tripp-Lite units (also 550VA), they would kill power to workstations too often to be just a fluke unit or two. I will not buy Tripp-Lite battery products again.

As for not having a replaceable battery: For this cost there is no point in fudging with a new battery. Just buy another one to replace it.

5 out of 5 eggs

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: it works as it should

Cons: none come to mind

Other Thoughts: It's being used to prevent hard shut downs of a nas in case of power failure. I tested it and it went for at least 10 minutes.

I'm not sure how low the battery got in 10 minutes but I decided that was sufficient and plugged it back in. I'm guessing it will hold out for at least 20-30 minutes with a small load like a two drive nas.

I set the nas to auto shut down when the battery reaches 50%.

3 out of 5 eggsI just bought the product.

This review is from: CyberPower Standby Series CP550SLG 550 VA 330 W 8 Outlets UPS

Pros: It's cost. It's inexpensive compared to similar product offerings. Micr0c3nt3r is selling these for $40.00

Cons: Not really big cons, but there are some. The spacing of the outlets isn't really large enough to accommodate plugs for cellphones, routers, cable modems, etc..

The power saver software for apple computers seems to not exist on their website. Yes, there are screen shots of it on the site but I cannot find a download link at all. No CDROM or USB key included with the packaging containing any software.

Other Thoughts: For the money you can't expect much. Yes, you cannot replace the battery in this unit but for the price of a replacement battery you could buy another one.
