## Description

Review: Takes mains outages in its stride - I bought this UPS a couple of months ago because the mains was becoming unstable with the lights flickering badly etc. (later traced by the utility company to a poor connection out in the street). Two days after I installed it and connected my PC, Router and Smart TV, the mains went unreliable with more flickering lights and clocks resetting etc., but the connected router and PC just continued working as normal. There have been a couple of momentary mains outages of a few seconds since and again the PC etc. had no problems. I also discovered on the Eaton website there's a form to fill in for the monitor software, I put something like private domestic user and was sent a link to a slightly older but perfectly functional and useful piece of software to monitor the current status and alarms. The distance between the two rows of sockets for filtered and filtered+UPS is larger than on some other UPS units which means some bulkier adaptor type plugs rather than the normal plug size can be accommodated. It also has a slide out panel on the base giving access to the battery which means it can easily be swapped out when at the end of its serviceable life. This makes me think this is a unit built to last. I am very pleased with my purchase which is performing flawlessly and wouldn't want to be without it.
Review: Brilliant and saved my RAID drive a couple of times.... - A great looking and compact UPS and easy to mount. I've used the mounting holes that's meant for walls and reinforced it with a couple of heavy duty straps under my height adjustable table, because I didn't want a number of un-sightly cables risk getting caught as I raise my desk. On one side of the strip is surge protection and the other uses the UPS, I didn't know this at first as I skipped the instructions and was wondering why it wasn't working! I got this was for my NVMe RAID which is very sensitive when power is suddenly cut and I risk a 2 day rebuild/re-install, I've already had it come on twice when the lights started flickering and thank goodness I had this. It comes with a long USB cable for communication and my Mac already has a fantastic built-in feature that brings-up a message in the middle of the screen, warning you're now running on UPS battery and to save/back-up etc. there's also a battery level indicator on the desktop strip. I'm running a power-hungry 40inch curved LG monitor, a RAID SSD and NVMe RAID, Macbook M1 Max, various SSD HD, a Thunder Bolt 4 hub and a Wifi6e router - when the power goes, there is a low level alarm and I get around 7 minutes to save and power down, which is more than enough, but luckily we only get very short power outage in London. Highly recommended and everyone should get one to protect their IT equipment.

## Questions & Answers

**Q: What is the manufacturer warrantee for this ups ?**
A: Thank you for your question. The 3S Mini comes with a 2 year manufacturer warranty.

**Q: Does it really have a power factor of just 0.4?**
A: No  all this means is it will provide 9 minutes of full power for 550 Watts of items,  should domestic power fail.  So if for example if you were powering a 150watt pc   ,you would have enough power for 27 minutes while the domestic power is off

**Q: My orbi rbr50 router is 12v 3.5a will this provide enough power to run it? description says 12v 3a, so should i assume no?**
A: Thank you for the question. This UPS would not be sufficient to power your router. I would recommend taking a look at our 3S 550B UPS as a potential alternative https://www.amazon.co.uk//Eaton-550B-UPS-Uninterruptible-Interface-Black-white/dp/B0B3RS2986

**Q: Does anyone know whether this ups is usb compatible with the wd my cloud range, specifically the pr4100 nas? i can’t see it on their compatible list.**
A: I have a MYCLOUD drive attached to my ups.  Provided the total power consumption doesn't exceed the plated output (510 watts on mine) you should be fine.

### ⭐ Batteries failed prematurely - may have no minimum voltage cut-off
*by A***A on 9 July 2023*

I own three of these units. Two worked great during a power cut yesterday, but one of them instantly dropped the output power. They are all around 12 months old. The one unit which failed had actually been fully discharged once, several months ago during a previous power cut. The other two units did not fully discharge, because they have very light loads (~3 watts vs the ~9 watts attached to the failed unit). Both of the lipo cells inside (TP LI-ION 3.7V ICR18650 2200mAh MH46259 UD020) now read at roughly 0.125 volts, so my /assumption/ is that these are unprotected cells and the unit itself does not have a low-voltage automatic cutoff. This is extremely problematic, because whenever there's a lengthy power cut, there is a solid risk that the unit itself will then be bricked unless you want to manually replace the lipo cells inside. So I'm afraid I need to give the "overall rating" as just one star because of this. Sorry, Eaton. Unless I'm mistaken and the one unit is faulty, then you will need to release a revision 2.0 which includes proper cell protection. Ideally they would auto power-off at, say, 20% power remaining. Perhaps even make the percentage/voltage configurable with a DIP switch somewhere, but obviously a DIP switch would add slightly to the materials cost & the plastics would need redesigning, so a straightforward X% cut-off would be the most reasonable thing to implement.
