Intended to keep a laptop alive for the remainder of our church service is laptop runs out. Should have lots of capacity, but watch out - the total power available is not directly related to the backup time, which can really be minutes. But this was the most we could afford, so buyer -do more research than I do. We have to turn off all warnings of course, so the unit lights give almost no indication of charge.

I've had these battery back ups before, but this one I've had less than 3 months and it randomly sets off a screaming alarm and the light blinks. I have to turn it off, unplug things then reset and turn it back on before plugging things back in. First time, okay, maybe a fluke, but it has done it 3 or 4 times already, I think it's time to take it back, must be a dud, the others I have had lasted for years and didn't do that.

Sounds like the internal battery may be faulty. Please reach out to our support team at 877.297.6937 and we'd be happy to assist. We look forward to hearing from you! <img src="https://s3.amazonaws.com/stratos-logos/logos/CyberPower.jpg" alt="CyberPower" title="CyberPower" style="display: block !important; margin-top: 2em !important; border: 1px solid #ccc !important; padding: 2px !important; background-color: white !important;"/>

The product is ok but the loud beeping when a problem occurs is the worst.

I used it to back up power for an internet modem and a wireless router. It does its fine. However, after a few years being plugged, it does not maintain an acceptable duration during power outages. It is somewhat disappointing that it doesn't last long before the backup battery needs to be replaced.

As a UPS/Battery backup, this unit works fine. HOWEVER, if you want to use it to shut down a PC if power starts to run low, it does NOT work very well. After a power hit, the software gets confused, and at the end of a timed period IT DROPS POWER COMPLETELY WITHOUT WARNING. Their support people think that is a feature, I see it as a MAJOR FLAW. So, if you want to use it without hooking up to a USB port, its fine, otherwise, bewere.

Doesn't last as long as I expected. It has an annoying recurring beep when the power goes out, but that can be disables.

Alarm has sounded 3 times since owning. Seems to have trouble with 300W aquarium heater, even though it meets the specs.

Hello DTrane,
This product was not designed to be used with aquariums. We suggest contacting the supplier of the aquarium for suggestions that meet your needs. Thank you!

Bought these for my home computer and 3d printers. With the specs on these they should handle my 500w 3d printers without an issue. Every time the heat bed starts to warm up the alarm goes off. Also if my computer is doing anything more then office and internet it starts beeping as well. I didn't think it would be an issue unless the power went out.

These units are not designed to power anything with a heating element as often they cause an in-rush current when starting to heat up, which may overload the UPS. This UPS can handle a total of 650 Volt-Amps of power usage, however the battery outlets max out at 360 Watts. Any more power draw than that and it will overload the UPS, which may be the beeping you are hearing.

Surge protector side worked well. Followed instructions and charged the battery. but the battery side never worked. it would immediately just beep. Was able to return as defective though.

So far I’ve only gotten roughly 13 months from each one I have purchased which makes them last longer than the warranty and that’s it

Doesn't handle the power draw demands from a Mac Pro at startup well, but does just fine after everything is running. My APC 550VA never stumbled at startup like this does (gives alert that there's battery drain occurring during startup), but the Mac Pro starts and then has no issues thereafter.

We’ve had it for less than a month. Power went out during the recent winds. It turned off. It did work when we turned the power off manually a week before for some work, so no clue why it stopped this time. Gonna have to exchange it.

This is the 3rd one I have purchased. They don't last long and are quite expensive
Hemdawg Posted
I bought this in case of power outage and we did lose power but it only lasted about 10 minutes! I was very disappointed that it did not last longer!

Thank you for submitting your review. There are always larger units but in general UPS units are designed to provide enough time to save what you're working on and to shut down properly. The SX650U is estimated to give about 9 minutes at 200 watts of load. If you are having issues with the unit, please reach out to our support team at 877-297-6937 and we'd be happy to assist. <img src="https://s3.amazonaws.com/stratos-logos/logos/CyberPower.jpg" alt="CyberPower" title="CyberPower" style="display: block !important; margin-top: 2em !important; border: 1px solid #ccc !important; padding: 2px !important; background-color: white !important;"/>

I am giving it this rating because the power button is located by the battery backup's outlets and it can be easily covered up by using the top outlet.

Does not seem to exceed expectations from a standard battery back-up system. Have not experienced a power-outage to properly test the system.

paid full price for this item, but received as OPEN BOX ITEM. No instruction book no USB cable. Very disappointed, no response from the store
