APCby Schneider Electric BACK-UPS ES - BE850G2-UK - Uninterruptible Power Supply 850VA (8 Outlets, Surge Protected, 2 USB Charging Ports), Black, Pack of 1

An excellent UPS for protecting home or very small business IT systems. A tested and effective design giving good electrical protection to devices running from the battery plus surge protection and limited ability to charge mobile devices. Note that this size battery (850VA) won't keep full PC systems operating for long, but is ideal to allow graceful shutdowns and keeping routers running to maintain internet access via mobile devices (charged ideally by other means) during an extended power cut.The UPS works very well with recent Apple Macs - it is detected directly by MacOS as a UPS and needs no extra software. Easy and effective if you just want a safe and automatic way of powering down your Mac in the case of a power cut.In contrast, the provided Windows PowerChute software looks old-fashioned and is a little fiddly but is very powerful and useful. It gives detailed information on energy usage and UPS performance and therefore indicates how long the unit's battery would be expected to power your IT system for. This lets you decide how to respond to a powercut and manage any business risk.Follow the documentation (download the full manual) and in particular plug the UPS directly into a mains socket rather than through e.g. a smart plug or home-plug adapter.Test that the battery will fully charge before putting a load on it, and make sure you are familiar with the different warning lights and audio beeps.The batteries are easy to replace when they reach the end of their useful life - the unit gives a warning when it considers this the case.In summary, a good small-capacity UPS with quality software. As such, it is different from the many battery-based chargers for mobile devices or a mini 'powerstation' as advertised for camping or solar charging. Not better or worse, they just meet different needs.

I purchased this UPS to provide continued power for my fibre broadband ONT (my router is on a separate UPS), so that I have continued broadband for a limited amount of time and digital voiceThe UPS is well built, and has 6 UPS enabled outlets, along with 2 surge protected outlets and 2 USB outlets. For the UPS and surge protected outlets, they are standard UK plug types which is useful and is easier to connect domestic devices than many other UPS devices that typically power IT related equipment and have the common cloverleaf cable outletsThe UPS seems to be of great quality and is easy to use, at it’s most basic level, plug in, power up, plug in devices and you’re ready to go. If used to provide power to desktops/laptops etc., a USB connection can also be used, along with some downloaded software to manage what happens if there’s a general power outageOverall, I believe this UBS to be very practical for a home user not looking just to connect IT equipment and in terms of the UPS products sold by my broadband/phone provider, BT, this is much more practical a product and provides much more functionalityI would definitely recommend and I will be looking to purchase further units to provide power to other key items in my houseUpdate: following a power outage as a local transformer blew up, I was without power for around 5 - 6 hours, during which time I had no problem in keeping my ONT alive as well as my backup 4G router, if my main BT router went offline (that’s served by a separate, much lower quality BT supplied UPS). For my purposes, a cannot recommend this UPS highly enough

We have about 50-100 (no joke) power cuts a year, it's ridiculous. No phone signal around here either, so no mobile internet when the power is off!I've had this for over a year now and it's still running just fine. I get about 15-30 mins with a router, firewall(on an i3 tower) and 8 port poe switch with two devices on poe.Charges your phone up nicely too 😂If you constant power cuts, it's worth it.

Couldn't find much info regards UPS and the UGREEN NAS DXP 4800+So here it is:Bought the APC BACK-UPS ES - BE650G2-UK (£107 on 2025-07-15).Arrived, as new with a Leoch DJW12-9.0 battery. Was fully charged, or was reporting fully charged when it arrived.Did some quick tests with a lamp attached and all behaving as you would expect. Light stayed on if power was cut.Connected the NAS, attached the supplied cable - network plug into UPS and USB into the NAS.Booted the NAS and went to: Ugreen OS > Control Panel > Hardware & Power > UPSUPS was recognized as American Power Conversion Back-UPS BE650G2 FW497200G-497300GThe Ugreen control panel also shoes the power capacity of the UPS. Useful.Set protection mode to Auto Shutdown. Set wait time to Minimum Value in custom time = 5 mins.Unplugged the UPS. the NAS detected the power out and reported it was shutting down in 5 mins. Which it did.UPS battery went from 97% to 88% in that time. other devices connected were 3 active External USB drives and a lamp.Reconnected power and restarted NAS. During boot, the lamp flashed, the NAS shutdown and the UPS power light flashed red for a second. Potentially overloaded? Unplugged lamp and tried again and NAS booted fine.Curious, I'm not sure I'm near the 400w limit with a NAS (with 3 HDDs and 2 NVMEs - NAS PSU is 150w), 3 external USBs HDDs (est 25w each) and a 7.5w lamp....In my case - the UPS is only for the NAS. It will be the only thing plugged into it (maybe a router as well).So yes, this particular UPS works with the UGREEN NAS DXP 4800 plus.Other benefits - has a user swappable battery. From what I've read the batteries might only last a few years, so option to swap out for approx £30 instead of buying a new UPS is good.The UPS is a chunky. But has 8 sockets, 6 of them battery protected.Doesn't seem to make any noise (apart from beeps when power is out) - not fan noise etc.Haven't tested Powerchute control software etc - I'm not planning on connecting my PC to it.Screenshot attached of the UPS info in the UGREEN OS.4 Stars - Expensive, especially with a limited life on the battery, but it is also overkill for my specific needs. But no other options seem to be available - Ideally a one plug NAS focused basic UPS for home use. Ugreen have something (ugreen 120w dc ups) but its not available outside China yet. The blip during boot also needs more investigation.
