Runs a lot warmer compared to my 1500VA APC UPS, But otherwise works as expected.

The fact that the batteries are not user replaceable is also a major issue for me.

Operation would not burden a user, but would make information available on demand.

I gave it 4 stars for one reason: I would prefer a user replaceable battery bay.

Normally, I would rate that as a pretty good success rate, but we just found out that these units don't have user replaceable batteries

Without user replaceable cells, most people will either scrap the unit or send it in to TrippLite for what I would imagine to be an expensive battery replacement service.

I contacted Tripp Lite support (which costs you a long distance call, because they do not have a 1-800 number!!

I contacted Tripp Lite support about this issue, and they claimed that this is standard behavior

The clearly defective units are one thing, but the refusal to acknowledge the problem from Tripp Lite support is just unacceptable from a supposed industry leader

We contacted Tripp Lite support about this, and they have so far done nothing but insist that this problem is 'normal' for when running a PC off the UPS.This tells me one of a few things has to be true:1

A recent call to the Tripp Lite Support Team to discuss these issues was met with a brick wall for Mac support - but after prodding the first tech into getting a supervisor on the line, he indicated that a Mac version of their

and I trust this device with some very expensive computer equiptment

The device is good for three hours, though my electrical service was out for about 10 minutes.

This was a purely cosmetic problem, since the device was working perfectly

However it would be a great device if Tripp Lite fixed these display issues.

This is such a good price because they are trying to unload

Shipped promptly, great price, met the objective very well.

This is a good way to protect your electronics at a cheaper price than APC.

This was the best price around and the system will out rank all in it's price range

They not be APC but they are better than what I had and at a good price point.

Now the surge protection only side is great for things like speakers and printers, but if you plug your computer into the wrong side, you won't get the battery backup feature.

Like most ups, half of the outlets are surge and battery backup, the other half are just surge protection.

Has 4 power backup outlets and 4 surge protection outlets

some outlets on battery back-up, others just on surge protection

Like the option of 5 plugs for surge protection as well as 5 plugs for battery backup.

Tripp Lite has been good to replace them but it can't restore my faith in their power protection products.

Tripp Lite says that it works with the 64bit system however I NEVER have been able to get it to work

Though to top off my story, the Tripp-Lite was so bad the guy didn't want to pay return

This Tripp Lite was easy to set up and I have full confidence in it

So far, the Tripp Lite has worked well, providing power to my computer during several power 'blinks'.

Great product, quickly shipped and perfect for my sensitive electronics.

Very nice product, and the beeping can be turned off fairly easily.

The product I received my be defective because it doesn't keep equipment powered at all during a power loss even though the display shows as ~80% power draw

The product is great, tell me exactly what I need to know

Good product,, always good to have proper protection for electronics now days.

This time the unit worked as it should, display showed full charge, and with a two hour power failure earlier this week it ran gave me time to shut the system down

FreeBSD and MidnightBSD to panic as it thinks it's an input device (mouse etc

Beware as they just shut off and never turn back on again.

This Smartpro battery backup works exactly as advertised.

I feel like there’s some false advertising going on here

Also, the Dish receiver designers are apparently so good that the unit has no way to cycle power except by unplugging--not good when software locks up

Also, if you are using these in a home theater environment, where it will be visible, I do like that you could choose to linearly dim the display (slide dimmer switch) or pop it out and rotate it 90 degrees so it can sit vertical or horizontal

It is fortunate that before the display stopped working I was able to configure the device to indicate that it had an external battery attached and show estimated battery run times accordingly

I have replaced about 60 batteries, around 11 volts (according to a Fluke voltmeter--NOT the internal inaccurate display), which is when we discovered they fail to power a small PC for more than 15 seconds

I bought this one over others like it for its extra battery protected outlets, the display, and the power it puts out

A control to dim the display would have been a nice addition

However, capacity, functions and smoothing out power to my high end components worked very well through a power outage.

I have lost a tv to surges and this little unit has been working great for 3+ years.

Update on September 28, 2012:The display is currently working, but has stopped and started working a number of times during the months I have owned the unit.

I've worked in IT support for 10 years, and have not ever had a problem with Tripp Lite products, and I used to recommend them to my friends and clients regularly

The device has worked flawlessly, im happy to know my tv is safe.

and it's not worth dealing with the manufacturer.

In all, this is a great unit and for 1000VA, it's a good deal.

I have had my unit almost a month and it still smells like burning elctronics

Came home to find unit dead, no ac voltage out of battery back-up outlets

Called tripplite support, very helpful but unit still dead

The unit is completely unresponsive and has definitely had only light usage

Beware as they just shut off and never turn back on again.

Computer worked as before

This time the unit worked as it should, display showed full charge, and with a two hour power failure earlier this week it ran gave me time to shut the system down

Great Product worked perfect A+++

So, my brand new computer would lose power, and restart at random intervals

They work fine with my TV and stereo, however computers that use Power Factor Correction (PFC) power supplies may not tolerate the power quality that comes from the unit when running on battery.

The battery would not kick in and my computer would be shut down and my TV would lose all user settings

The Tripp lite was one of them that died but my computer and accessories that were plugged into it were fine

The UPS was damaged and, also, our computer, our printer, our internet modem, our monitor and our DSL line

The fans will be on MAXIMUM ATTACK for an hour while the batteries top up

My only complaint is that this UPS has an extremely loud fan.

As others have said, the fan is really loud and it runs ALL THE TIME

The UPS units also become extremely hot when on battery, and the cooling fans are very loud, even when not on battery

But then, after @ 6 months ownership I started to notice strange things.

Admittedly this product isn't the most exciting thing to review... really it just sits there doing its thing.

We have had this unit in service for over a year and have nothing but good thing to say about the clean and stable backup power being provided.

The good thing is that it can be turned off when not needed.

I have better things to do fight with this thing or with customer service

I've got several of these hooked up to A/V equipment in my home where the power is not super clean.

Basically the inverter supplies a clean power source all the time weather using the wall outlet or the 12V battery

We have had this unit in service for over a year and have nothing but good thing to say about the clean and stable backup power being provided.

there's no way to "power them back on," they just lose power

that all eight had clean power and all eight were on the battery back-up circuit.

Computer worked as before

But if it goes south, as mine did today (shut off intermittently, failed self-test by shutting down because the battery was on its last legs

The first two worked exactly 35 months and about 20 days, and then failed

Our results for those 125 Oneac units:initial install: 0 DOA units.6 months later: 0 dead units.12 months later: 0 dead units

Running a 2016 iMac, audio interface, Cisco network switch, and iMac peripherals (external hard drives, etc) and still only hitting about 15% of the load, so my battery backup time is calculated to be ~35 minutes.

All devices connected to the UPS will suddenly get cut off from power; this is very bad for hard drives!

I guess I was lucky that the at the time of shut down, my hard drive was not writing on the disk

It was quite panic, as such shut off may cause hard drive damage (actually file structure damage) if hard drive was at same time writing on the disk

No lightning strike, etc, the UPS just failed to come back on when the power bumped so my filter pumps stopped working.

When the batteries on my APC BR1500G failed the self test after 5 years I figured this would have been a good time to get a rack mount UPS for my server rack

There is not a single unit on the market that is 100% safe during a direct lightning strike, so make sure you have a backup

When the batteries on my APC BR1500G failed the self test after 5 years I figured this would have been a good time to get a rack mount UPS for my server rack

I had a storm last year that crippled about $3000 worth of equipment when a bolt of lightning struck very close
