  Crazy value for money

  Frankly for the price it's really good. If you have small cuts it's important enough to protect your computer or other devices.
  Personally, I took two, box and setup, because life in the village can sometimes bring nasty surprises!

  Everything is OK

  This is my second inverter, the first was a different brand and failed me after 6 years. I appreciate this type of product in the event of an unexpected power cut, which allows me to save my work in progress (and the progress of my video game...). So far, so good. However, I do regret the little booklet, which doesn't explain much for a novice - just a few drawings. It should also be made clearer that before any use, the battery should be left to charge for at least 24 hours - I left it for 3 days. My old inverter was much more exhaustive on this point. That's all, and... thank you LDLC for the fast delivery.

  Mitigated

  It's a good product for protecting equipment sensitive to voltage surges, but it's relatively fragile; the previous one only lasted 28 months.

  Excellent

  The product suits me perfectly, in the event of a power cut there are no problems, the UPS takes over straight away. And by installing "UPS companion" it is possible to adjust quite a few things, the input voltage, the consumption in real time (between 200 and 250 W for me - hypervisor with a lot of disks and ram), the charge level and the estimated running time on the battery.
  
  the criteria for automatic system shutdown are :
  - Battery operation for x minutes
  - Battery life less than or equal to x minutes
  - Battery charge level less than x %.
  
  So there's no need to worry about short interruptions, and you can be sure of an orderly shutdown if things go wrong for a while.
  
  Recommended for anyone who has important data or, like me, hates losing work in progress.
  In principle, it's a convenience, but there can be unpleasant surprises during public works or other projects...

  VERY HAPPY - MEETS MY EXPECTATIONS

  This is my second inverter of this brand, the other being 10 years old, I had to replace the battery while waiting to do it, I ordered a new model to replace it at the same time, I run with an 800W power supply on my PC and it works without any problem, as indicated.

  Meets my expectations

  Does the job, quite imposing (I thought it would be smaller and lighter, take a good look at the dimensions).
  I had a problem with another model (the 450) after 5 months but the EATON after-sales service is extremely efficient and sent me a new one very quickly.

  Good quality

  Practical and well finished, a good investment that protects all your equipment. Make sure you have enough watts available before making your choice.

  Perfect for protecting my PC

  Working from home, I had to buy a powerful PC. Unfortunately, I get a lot of power cuts at home. So I bought this UPS to protect my installation, and I have to say I'm not disappointed! The reaction time is extremely fast, because it's triggered by a micro-outage that doesn't even have time to disconnect my (unprotected) internet box.
  
  I highly recommend this product! (which has already protected my computer system a good twenty times since I installed it).

  Well thought-out ergonomics.

  It can be placed vertically, which takes up less space and provides easier access to the USB charging ports.
  Programmable system shutdown using UPS companion software, which can be downloaded free of charge from the Eaton website.
  User-replaceable battery.
  Totally silent, with no battery drain.

  Canon printer incompatibility

  When my printer (Canon LBP223dw), plugged into the "master" sockets, is activated, the UPS goes into fault mode: the computer and screen lose power, the indicator light goes red, and there's an audible alarm.
  Connected to the lightning protection socket, all is well.
  This phenomenon occurs on both inverters received at the same time
  No problems of this kind with the previous device, which has become obsolete.
  Eaton support (contacted 3 weeks ago) has not yet given me any answer.

  Excellent!

  Yes, it's expensive, but having had between 10-20 micro-cuts last year, I was fed up with my PC cutting out. It's really great because it allows my PC (gaming config) to stay on during power cuts and if the power cut lasts, you can even stay on it for a while while to finish what you're doing.
  
  Mind you, it doesn't look like it in the photo, but it's big and heavy!

  Good product (small but)

  It's a good product that works well but my Windows 7 PC boots on it when I start up, so I have to remove the USB.
  I have to remove the USB and for the time being there is no solution from the manufacturer.

  Eaton 850VA inverter

  The product works well, even under debian (Nut package) or from the desktop
  the PC shutdown is clean, correct autonomy for a desktop machine
  it can be used without connecting it to a PC, it automatically shuts down when the battery is below 20%.
  not used the Eaton software, windows or Linux has a good management of the UPS without this program
  Good product

  Hello,
  
  I received this yesterday, and when I unpacked it I saw that the power button is on the same side as the power and USB inputs, and the on/off indicator.

  Very good quality inverter

  I've tested it by disconnecting the inverter plug from the wall and my pc with a 450w power supply. I tested it by disconnecting the inverter plug from the wall and my pc with a 450w power supply, the 35w screen and the 20w speakers all stayed on, so the test is approved and it works well. I have only had it since January 2021 so 3 months of use so I will have to wait and see. I recommend this UPS. The inverter was delivered to me directly in the eaton box and the box was damaged during transport. fortunately the inverter was not damaged.

  Quality product well packaged and delivered on time!

  The product was received without a hitch, well packaged and delivered without defects. The product is very good, the sockets are well arranged for large chargers without impinging on the other sockets. I have tried to cut the power to the socket and the relay is taken directly without any loss. The only problem is that the optional software (free) which is supposed to save and dye the PC automatically disconnects frequently, but I think that this is due to my PC and does not prevent the inverter from working, you just have to do the procedure manually, but for my use it is not annoying. The delivery was smooth and on time. The delivery was smooth and on time. I'm not sure if I'm going to be able to get the product, but I'm sure I'll be able to get the product in the future. I'm very happy with the service and the quality of the product. I have been using LDLC for several years now and have had no problems with them so far. I would recommend the product (although we will have to see how long it lasts).The warranty is reassuring, (2 years parts and battery included and lifetime warranty of the hardware on top in case of protection failure.) The option of warranty extension is very cheap unlike many other sites. I'm not a fan of the site, but 2 years of warranty for a few euros is not a big loss, even if I didn't take it this time. I also recommend LDLC, which works very well.

  No problem so far

  The inverter does its job. Compact and quiet. I hope it will last a few years. I have not yet been able to test the behaviour in the event of a power cut.

  Good but...

  Good inverter that works perfectly, however it is a shame that only the 4 plugs powered by the battery are cut when the inverter is turned off, the other 4 are not cut or you have to unplug it.
  If I had known I might not have taken this model, another important piece of information not reported.

  Very good inverter

  Living in an old country house where power cuts are frequent (at least 1 per week), I needed an inverter to overcome this inconvenience.
  What can I say, well it activates instantly with a little beep without any freeze of the PC or the box.
  I'll see now what it will do for the life of the lead battery.

  Perfect

  Ok, I gave 10/10, because currently the product gives complete satisfaction. We will see how the product and its battery will age. I tried this product, because I already had other inverters of another brand. These other inverters worked perfectly for three, four or five years. Then they would start to "screw up". The unit would make a loud noise, even when none of the connected appliances were working (at 02:00, that's chi...). It was not a battery problem. To stop the noise, you had to unplug everything. In short, currently perfect, hoping that it will age well. Advantage between this inverter and the one that "disconnects", it's the same battery model.

  Exactly what I needed

  Corresponds perfectly to my expectations.
  4 outlets powered as backup while being surge protected plus 4 surge protected outlets.
  The unit powers my 2-drive NAS, an additional 4-drive box connected to the NAS, my modem and my wifi router.
  In addition, it protects the TV, the home cinema and the amp.
  As luck would have it, there was a power outage the day after the installation.
  It's magical! The power went out, the box beeped and sent a signal to the NAS which took care of putting the 6 disks in standby in a secure way.
  The power was restored after 10 minutes and everything started up again as if nothing had happened.
  Since my modem and router are powered by the box, I could still use my laptop to surf or access local documents.
  What a pleasure!
  It's a pity that you can't have it all in black, hence the 9/10.

  Great delivery and product, arrived quickly despite Covid19

  I was very pleased with the speed of delivery despite the difficulties associated with the current containment (Covid19). I am very pleased with the speed of delivery despite the difficulties of the current containment (Covid19) and your teams working during this period.
  This UPS meets my expectations perfectly. I had a problem with the screen turning off every time the central heating thermostat was switched on, the plug is now correctly filtered and the problem has disappeared.
  -Can hang the unit on the wall
  (I don't use it but it can be a good idea in some cases)
  -Access to the batteries without tools through the bottom of the device
  -The plugs are placed upwards: less cables on the floor if the device is on the PC
  -Access to the sockets without taking the device out
  -When placed on the PC, it can also be placed in the cabinet because it is not too high
  -Sufficient sockets
  -Very practical controls & USB sockets on the front panel
  Really recommendable device
  Only downside (-1 pt): the user manual (only graphic) is very small and does not explain the use properly
