MARUSON 2000VA UPS, AVR, 735J Surge Protection, 8 Outlets, Line Interactive Uninterruptible Power Supply Battery Backup System, TUV Certified, 2000VA/1200W, PRO-2000LCD

I recently added a Maruson UPS to my setup, which has been performing reliably for several weeks. This 1000-watt, 2000 VA UPS effortlessly switches to battery during power outages, providing 5-10 minutes of backup—enough to shut down Windows using the included USB software safely. It powers my main PC/server, ensuring a stable 60 Hz sine wave output perfect for sensitive electronics. The only downside is the non-recyclable styrofoam packaging. It's essential for anyone in areas with frequent power fluctuations.

Came across Maruson when I was looking to replace an older UPS that had wonked out on me. So ordered and hooked this one up. Running it for the last few weeks, I’ve been pleasantly surprised at the great value I’ve got out of this one.I have it hooked up to my main pc which also happens to be a server (files, printers, etc) for the house. Tested it a few times by flipping the breaker and the unit transfers seamlessly to battery power. Battery lasts 5-10 minutes (also shows up on the LCD) which is pretty standard and plenty for the auto windows shut down to kick in. The software and USB hook up is a lifesaver since you can set it up for the auto windows shutdown.Anyways, great value and I’m glad I didn’t have to shell out an extra $100-200 for a fancy one that does exactly the same thing.

This review is based a on a very limited use of the units as I've only had them about a week.I purchased two 800VA/400W units for backup power and line conditioning for a home internet and security system. The units arrived with batteries mostly charged (minimal time plugged in to AC power was required for the batteries to be back at 100% charge). The units are small and sleek, with an LCD display that turns off after a short period. Briefly pushing the power button again illuminates the LCD display.Downloaded and installed the Power Management software and was able to view/modify unit configuration from a laptop using the USB cables included with the units.First impression is that these units are a real value for the price with both battery backup and line conditioning features (as opposed to only battery-supplied power).The only downside I've seen so far is that the clamshell cases are plastic (not metal) and both units arrived new with the clamshells not aligned properly. I don't know if this was due to the shipping company manhandling the packages or if the assembly process isn't as precise as you might like. Unscrewing the clam shell cases allowed me to reseat both to fit together as they should, but one of them apparently has one screw hole with a broken screw socket (I can hear it rolling inside the unit when I tilt it sideways) and there's nothing for that screw to tighten in the single corner of one unit.Otherwise, I feel like I'm getting a pretty good value for the price on these units compared to the price of similarly-featured competitor products.

I'm here to give my opinion. I had it on but the time hadn't come to test how efficient it was. When I ran out of power, what I feared most happened. It barely lasted 15 minutes and I only had a PS5 and a 42-inch TV connected. I don't recommend it. Don't even think about buying it, you'll lose your money.

This is a 1000 watt, 2000 VA uninterruptible power supply to protect Electronics. It has a USB interface to my windows PC that has a multitude of diagnostics to keep track of how to UPS is doing.Anyone that lives in an area that has outages, brownouts, or over-voltage events, should have a UPS feeding their electronics. The output of this UPS is a perfect 60 Hz sign wave, which is exactly what you need to have.

IT DOESN'T HAVE WIFI, HAVEN'T NEEDED TECH SUPPORT (YET), ITS JUST A GREAT BIG UPS SYSTEM, POWERING A GREAT BIG RACK SERVER. AND IT WON'T GO INTO SLEEP MODE, CAUSE IT CAN'T. WASN'T BUILT THAT WAY, NOT SURE WHO WROTE THE REVIEW QUESTIONS UP, BUT NONE OF THEM APPLY

It had a two year warrantee, it died at 2.5 years. I have other older UPS's in the same room, this product didn't last nearly as long as it should have.Instead of 1 star, I gave them 3 stars because the seller was very responsive, even if it was to tell me that it was out of warrantee and tough luck. They even followed up and said that I could buy a new battery and they would do the labor for free. great seller, selling a crummy product.

I have $20,000 worth of equipment connected to two separate ones. I don't know why when I look back now and see 2 negative reviews by @Gob, and @Tomf. Their claims aren't accurate by any means. This Is a fantastic UPS and the seller had no impact on my verified response on the product. It's just disheartening to see people bash on a product that is cheaper and more energy efficient then the other 1200w ones out there on the market. Hopefully people read more into what they buy and problems like these could be avoided. *Cough, Cough* Have a nice day all!!!
