Tripp Lite 750VA UPS Battery Backup Surge Protector Efficient ENERGY-STAR Certified, AVR, 12-Outlet Uninterruptible Power Supply, Dataline Protection, 3-Year Warranty & 100,000 Insurance (ECO750UPS)

Everything about this backup surge protector is as advertised. It works great to level out the power and helps eliminate Brownouts. Very satisfied.

I first purchased this item in August 2017, and then again in October 2020. Tripp-Lite has sold at least 2 versions of the product with the same product name ECO550UPS, but with 2 different package styles. The same ASIN number, B001OQBMLA, was used on Amazon for both package styles.- The one I purchased in 2017 has UPC # 037332143884, and made in China, per the carton label. Besides the product name ECO550UPS, there is a secondary identifier BC7889. This unit has a case style that is not as tall, and is wider than the more recent one. This case style allowed for wider distribution of the outlets, and enabled easier access to the outlets (see my provided pic). Also note that it provides only 8 total outlets. Also, this style has no access panel to replace the battery, however, it may be accessed by removing 3 case screws and opening the case.- The one I purchased in 2020 has UPC # 037332211064, and made in Vietnam, per the carton label. Besides the product name ECO550UPS, there is a secondary identifier BC87FB. This unit has a case style that is taller, and is narrower than the older one. This case style allows for narrower distribution of the outlets, and makes access to the outlets more difficult. The main product image for this page shows the more recent product. Also note that it provides 10 total outlets (vs 8 for the previous version). This case style has an access panel to access the battery for replacement.The product includes a 3 year warranty, and I can report that the battery in the unit I purchased in Aug 2017, failed in Jan 2020 (just a little over 3 years). Failure was indicated by a one-beep alert that repeated every 15 minutes. Replacement battery cost (from a local battery vendor) was less than half the price of a new UPS, so it is well worth replacing the battery if you are even a little bit handy.

I have to say the product arrived sooner than expected. The surge protector works well for our purposes.

I bought this ups over a month ago and it messed up on day one. I plugged it in and the ups gave a big spark. I hoped I didn't mess something up in it. I called tech support and they said they would look into an alternate ups. I told them I may have blown out the warranty because I plugged in my devices first before plugging in the ups. The tech said it's ok it was an honest mistake. So a week goes by and no word into the replacement. I called back and the second tech said they have the second ups suggestion and it would be 5 to 6 days before I would get the email. I wasn't really looking for a replacement. They offered to replace it. They said they were really busy. I thought, really, there to busy to take care of a customer. well, it's been three weeks and no contact. So they can keep their new ups. If they are to busy then they don't need my business. I had bought a second ups from Tripp Lite and it messed up eco1000lcd. The utility went off line 3 times. So it is now on my backup PC. I now have an APC ups on the way. I will never buy Tripp Lite again. As an added note, the master outlet didn't work. I thought it was because of the spark. The batt+surge work fine. So I'm not sure if I actually messed the thing up. Still I won't buy Tripp Lite again.

I've bought a few of these in different sizes and capacities and I've been impressed by each one of them. They're pretty small for what they can do and work well for us, so Tripp-Lite has become a go-to brand for me after some experiences with a competitor's units (a certain other vendor, let's call them Pamerican Cower Aversion, has exceptionally good support but I've had more issues with them than I'd like to.).Another reviewer has called these "toys" and said that they power off if there's not a sufficient load on them when on battery. I cannot say that I've had that problem; if I unplug the UPS and only plug a kill-a-watt on it for a very low load, the kill-a-watt stays on. Perhaps this customer left something plugged into the surge side? :)Also, contrary to the this reviewer's statements, the load requirement for Eco mode is specified in the manual which both comes with the unit and can be viewed online at Tripp-Lite's website... and if you're not going to use Eco mode, you can turn it off or simply buy a UPS that lacks the feature.

I operate a variety of sites where we have IT equipment in a location where we need a UPS but do not have a full rack of equipment. Generally I've been super happy with Tripplite equipment - and have had plenty of luck with the older SMART1500LCDT and similar small UPS models. Those are reliable and cost effective... But not this one. Most of the time these UPS are used to keep a switch and a router up - along perhaps with some other lower power draw equipment.The 1440VA 900W "ECO-Friendly" UPS is not a real UPS. Let me explain: First, by spec it requires a minimum power draw if in ECO mode. You can disable ECO mode - but even then it requires a small minimum power draw which Tripplite does not state in their specs. If that minimum power draw is not there - when it loses power, it will shutdown - and NOT switch to battery. So... ECO or not - that pretty much defeats the purpose of a UPS unless you know for SURE that your power draw will never be below the minimums. I tried fixing this using their manual, making sure all items were plugged into the "master" power outlet etc. No luck. Another one I have which pulls more power happen does not have this problem - but ill probably replace it b/c i just trust this model anymore.So - in short - unless you just don't REALLY care if the power stays up on a device - DO NOT use this product. The entire purpose of UPS is to keep the power on, which these fail to do.For this reason i'll call them toy UPSs - maybe meant for people who just want one to have one, or who need them for some compliance reason. Its even worse than a power strip! It turns the power off and never comes back on!!! LOL. But they make wonderful paperweights.

So far working good, have not had a power failure
