This Battery back up sucks.

Reviewed in the United States 🇺🇸 on August 1, 2022

Style: 750VAPattern: BatteryVerified Purchase

We purchased this for our fire department. It will not stay charged up. It is plugged in but about every three days it turns off and computer will shut done. When go to turn battery backup unit back on it just beeeeeps. And have to unplug it for several hours before it will let you turn it back on. We was having problems but thought was just a fluke and would work next time. But now it is past time to return for refund.
UPDATE ******
We did call the company and they made it good and sent us a new one and it is working good. That one must of just been a defect. So I have changed my review to 4 stars

Data Protection Feature Poorly Implemented

Reviewed in the United States 🇺🇸 on August 14, 2020

Style: 700VAPattern: BatteryVerified Purchase

I picked this unit because of its low price and my good experience with Tripp-Lite's UPS products in the past. Also, this unit features automatic voltage regulation (AVR) which is unusual at this price point.

I've had it in operation for about two weeks and no problems there. However, the data protection feature - where you can feed thru an RJ-11 telephone or RJ-45 ethernet line for surge protection - seems poorly implemented.

When I installed the unit, I connected ethernet cables carrying 100baseT thru the data protection ports. Result: no connection. After trying a couple of different patch cords, I connected an ethernet cable tester to check continuity and found that the IN-OUT ports map 1-1, 2-2, 3-3, 4-5, 5-4 and 6 thru 8 no connection.

To give Tripp-Lite some credit, the ad for the unit specifies that it will protect telephone and 10baseT service.
10baseT is defined as using a single twisted pair. Presumably, if that pair were connected via pins 1 thru 3, it would pass data. So T-L's claim that it will protect a 10baseT data connection - narrowly defined - is true. But it's an air gap for fast or gigabyte ethernet. Useless! And who the heck uses 10baseT anymore?

I emailed Tripp-Lite tech support about a week ago asking if this odd pinout for the data protection port was intentional or accidental, but I have not heard back.

I'll stay with four stars overall because the unit is otherwise working well and the loss of use of the data protection feature, while disappointing, is not a big issue for me.

Love, Love, Love Tripplite.

Reviewed in the United States 🇺🇸 on July 28, 2022

Style: 700VAPattern: BatteryVerified Purchase

When Hurricane sandy hit, my company's office in Nag's head was flooded.
Everyone followed our instructions to put all elecronics up on their desks and have none of them on the floor... but not everyone unplugged them.

When the building flooded, every computer behind a Tripp-lite UPS \ Surge supressor was undamaged.
The devices completely died, some with major electrical damage, but they did so in a manner where that surge was not passed on to the devices. I've heard time and time again how they honor their lifetime warranty, replacing any failed device you send them pictures of... but honestly, if it dies protecting my stuff, I feel they deserve more business and I'll happily buy replacements.

I have never lost any electronics behind a Tripp-lite. So when it came time to get some UPS units for my personal computers at home, I picked up these. I was very thrilled to see that without even loading software, I could plug in my desktops to the UPS with USB and it immediately told me the state of the battery as though I had a laptop. I could even set windows power management to do shut downs depending on battery percentage (just like a laptop). Again, this is all without power management software.

The price is excellent for what you pay for and I sleep better during storms knowing my equipment is protected.

Battery in my unit went bad with first power outage

Reviewed in the United States 🇺🇸 on May 16, 2022

Style: 750VAPattern: BatteryVerified Purchase

This is the first Tripp Lite product that I've ever had an issue with. I'm a long-time Tripp Lite fan and will continue to be.

There may have been an issue with the battery or something took out the battery charging capabilities, as the battery side of the unit failed right after a big storm took out our power. My other Tripp Lite devices, including one just like this one, had no issues are were on the same circuit.

Kudos to Amazon for taking care of the problem with a quick resolution.

Giving 4 stars instead of 5 due to the failure, but I would not have any issues purchasing another of this model in the future (provided it's replacement does not also fail!)

Quiet and Effective

Reviewed in the United States 🇺🇸 on October 25, 2020

Style: 750VAPattern: BatteryVerified Purchase

I bought this UPS to power my cable modem, wifi router, and hubitat hub just in case of a short power outage. We usually don't get length outages, but I wanted to protect from the occasional power dips and glitches so everything doesn't reboot (and for my hubitat hub to not get a corrupted database). My setup was tested a few times so far with very short power outages and it worked fine. It would beep once when the power went out, and that was it. No loud continuous beeps or chimes.

This backup unit is pretty heavy and large. I was planning to put it behind my two-drawer credenza, but it was just too wide and thick. Instead, I have it sitting on the floor just to the side of the credenza where it operates quietly (no buzzing at all). In all, I'm very happy with my purchase and hope it will power my devices long enough to last through future short power outages.

Update (12/11/2021): I've owned this UPS for over a year now and it's been working perfectly. It lays quietly on my office floor next to my credenza and powers my WiFi router, Cable Modem, and Hubitat Hub. I've had a few power outages and it worked great, keeping my devices powered up for about 2 hours before shutting down. No issues what so ever. I'm glad I made this purchase.

Terrible experience with Tripp Lite's order administration/RMA department

Reviewed in Canada 🇨🇦 on September 23, 2020

Style: 550VAPattern: BatteryVerified Purchase

Upon unboxing the AVR550U, there was a strong odour from the UPS. At first, I thought it was a plastic "new product" smell but it was something else. I left it running for a couple of days but the smell became a bit overwhelming and feared it was toxic, as I became nauseated to be in the same room as the device. I reached out to Tripp Lite support, who indicated they didn't have any reports of odours from the model I purchased, but they did have an issue with a different model and may have been a result of a varnish they use on the internals after the inspection & cleaning process. Tripp Lite support suggested putting it in my garage for a couple of days and the smell should dissipate, so I followed their suggestion. If their products are known to have toxic fumes, why wouldn't they air them out at the factory? There was nothing in the instructions saying we should be airing them out. After reconnecting it in my house, the same issue was occurring. Instead of doing an exchange with Amazon, I decided to do an RMA exchange; this way, Tripp Lite could inspect the product if there was some sort of manufacturing issue. The RMA arrived quickly, still has the same odour as the previous unit, but way less strong. I'm still wondering if this is going to cause any long term health effects. I noticed the 1st unit was made in China and the RMA was made in Vietnam. When trying to return the old product, that's when the multi week nightmare started. The Support team only initiates the RMA but doesn't support/deal with it beyond that; follow up has to be done with the Order Administration (OA) team. The OA team only respond to emails once a week, even though their automated reply says they will respond within a few hours. Phone calls to the Order Administration team ended up with me being directed to employees' voicemails, never to be returned. Tripp Lite does not appear to be set up to handle Canadian customers as it appears only 1 person from Tripp Lite USA deals with shipping/returns from Canada and he was not responsive. I had 30 days to return the product after the RMA process started and it took weeks of emails and follow up phone calls before I got a pre-paid courier pickup scheduled from them but likely only because I added Tripp Lite's Director of Customer Service and a generic email address for Tripp Lite Canada to the email chain. I was one day away from emailing their CEO because I didn't even get an email response from the Customer Service Director. This was the single worst retail experience I've ever had with a company in my life. Lessons learned for next time: 1) Always do exchanges via Amazon 2) Only buy APC brand UPS's going forward. I'm probably going to keep this unit but Tripp Lite has lost a customer for life because if I was to ever have an issue with one of their products and need warranty services, I will never want to deal with their Order Administration team again.

Always beeping randomly - No answer from the manufacturer

Reviewed in Canada 🇨🇦 on April 20, 2023

Style: 750VAPattern: BatteryVerified Purchase

Bought this unit a year ago.
Started having issue less then a month in.
The unit start beeping for no reason. Need to remove the battery every time.
I have less than 100w total plugged on the battery side.
Talked to Amazon and got the issue fixed but the problem reoccurred a month later.
Ask Amazon, and they told me to contact the manufacturer.
Been sending emails for more than 6 months now (4 Emails Total)
Not a single answer from the manufacturer.
I would look somewhere else if you care about quality and consumer support.

Poor quality control - Shipped TWO defective and mislabeled units!

Reviewed in Canada 🇨🇦 on January 4, 2022

Style: 900VAPattern: BatteryVerified Purchase

I used to love Eaton products, not anymore. Bought two of these new, both don't work!

I bought two of the AVR900u. Everything was great until the first power outage occurred, shortly after the Amazon return window ended, and the units' would not charge back up after power was restored.

Troubleshooting this I noticed that both units were mislabeled as AVR750u's and a small bit of solder fell out of one unit when it was turned over. Talk about bad quality control...

Eaton says they will replace the units, in February 2022, 4 months or so after I bought them, because they have a global shipping crisis. So basically, there's no reasonable warranty on these, you're going to have to wait for months if your unit doesn't work!

Test your unit with a power outage right away so you don't get messed over like me.
