Great! Unexpectedly put to the test right after installation!
Weather frequently causes power fluctuation and outages. Sometimes a short blip, other times for an hour or longer which is where this UPS comes in handy. This is less expensive than others in this power range due in part to the fact that it is not a true sine wave power source. That being said a simulated sine wave unit like this is perfect for office and computer needs, even gaming. I bought this to replace an old unit (different brand) that failed.When I unpacked this new unit it came with a coax cable, USB cable and a phone line cable. Each of these permit circuit surge protection to a cable TV line, computer network line and then the USB plugs into my computer to permit monitoring and planned PC shut down should power fail to allow smooth closing of programs and saving of data.For safety reasons and to keep batteries fresh the unit ships with one battery terminal disconnected. It is necessary to open the bottom of the case requiring a Phillips screwdriver. Once open you slide the battery out, pull the tucked-in cable and then slip it on to the only battery terminal without a wire. Very simple and quick. Pop the battery back in, screw the cover on and plug into the wall.The unit powered up immediately and showed a graph on the display indicating the battery has a full charge which is comforting. The display shows Battery Charge, AC Input indicating it is plugged in to a live power source, output voltage and a bar graph indicating the power load from components that are plugged in.On the front of the panel are two USB charging ports where you can plug in cell phones or tablets etc. The rear power sockets are arranged with five battery backup & surge protected plugs on the left and five surge protected only plugs on the right. On each side there is a single plug socket moved sufficiently away from the other four to permit a wide power brick to be plugged in.I like the fact that the lighted display panel turns off after a few seconds, so the glare is not present all of the time. The middle button on the front of the unit turns the display back on.Within an hour of installing this new unit my power went off for a minute! My computer and display never flickered and I did not lose any of the work in progress whereas in the past my PC would immediately shut down with just the slightest power outage of even a second. My network local five port switch is plugged into the UPS and likewise did no lose power or signal.I should note that this takes standard UPS batteries which can be replaced by the user & the device will alert when the batteries are beginning to fail. My computers stay powered on 24X7 and I generally get a couple years life out of these batteries before they require replacing.Another point in favor of this over an older very expensive name brand UPS is the fact that the noise level is very quiet! I have three 1500va units from three different brands in the same room and the most expensive UPS is noisy with the fan always running. (Yes, I cleaned out the unit with an air hose to see if that would reduce the noise – no help!)If you find this review of any use please mark it as helpful.

Back it up
Great UPS that hold its charge well, the price was reasonable and saved me a trip to MicroCenter for one of the same quality. I can get about 30 minutes or so and it stabilizes the power to a NVR for some camera’s. I definitely would buy again.

I ordered the product to replace a failing UPS, but was unable to test the new UPS before the return window closed.The battery that came with the unit was completely depleted, and the UPS started up with a “bad battery” error code the first time I turned it on. Since I was not able to do a return, I purchased a new battery. The unit functioned for 4 days, at which time it started to display the same error. The new battery was almost completely drained, while the unit was connected to power the whole time.

Je me sers de cette batterie de secours afin de garder actif mon routeur et réseau de système de surveillance WIFI lors de panne de courant. La batterie fait le travail tel que demandé mais compte tenu de la durée de charge, je suis un peu déçu. La batterie dure seulement 50 minutes. Pourtant, je n’ai qu’un modem/routeur et quelques caméras.

Good ups
