Tecnoware Power Systems - Uninterruptible Power Supply UK, 800VA, AVR Stabilizer for PC & Modem, DVR Surveillance, Silent Operation, Power Protection, UK Output, Black

The unit appears well made and was simple to set-up. No mains power lead is supplied (there is a reliance on you re-using one of the IEC cables you previously have in your set-up). Two interconnect cables are provided which is useful, however I needed to buy two more cables independently as there are 4 UPS outlets. The kit (when first installed) takes around 4 hours to reach 100% battery power and is silent in operation. If the power goes down then the battery kicks in pretty much instantaneously and it is only then when you get a significant increase in noise and a beeping sound to inform that the UPS is in operation (which can be silenced). I connected my UPS via USB to my computer and I can see power usage and set up various functions such as whether I want my computer to safely shut down in the event of loss of power. Instructions to use this software are average but workable. Registering is a nightmare and I've not managed to do it as the website is a mix of Italian and English and some options simply don't appear to work, feels a bit unfinished. In summary, good looking and slim device (but weighs about 10kg), quiet in normal operation. In tests it worked effectively and apparently it will give me around 20 minutes of backup power in the event of an issue (I have a hefty gaming PC, External SSD Drive, External HDD drive and a NAS server all connected up). So, good purchase for the money and worth it for piece of mind that power interruptions will be less likely to destroy my PC or data.

Ok so it looks nice, it does indeed keep the power on when the mains goes off. There its usefulness ends.Lets start with Documentation - there isn't any! There's a quick start guide with a link to the full guide, which as it happens is exactly the same quickstart guide. Which tells you - wait for it - to plug it in and plug your computer into it. Zero mention of the USB port to tell the computer when it's switched to battery, no mention of how any software works. Nothing it literally tells you how to plug in power plugs - how did I manage my life without this information?Ok so maybe the Software is ok right? well they tell you in the box to download the UPSilon2000 software and provide yet another dead link that leads nowhere. Ok so you go to their website, you find the exact model you bought, in my case the UPS ERA Plus 1200, and it takes you to a software download...for something called Tecnomanager. You install it and it doesn't work, now this might be because my PC simply couldn't find the device when it was plugged in - there was no device detected sounds or indications at all.So I tried my laptop, oh interesting I got a windows has found a device sound, for an unidentified universal controller, again the software does nothing, it doesn't connect, it doesn't find the device and there is not even a user manual for the software!So I figure hey plug the Qnap NAS into it, mhmm interesting, go to plugged in external devices guess what - there is no device detected!So my PC and NAS won't detect it, my laptop detects it as an unidentified universal controller and does nothing. To make matters worse you're going to have no idea if you are supposed to use the UPSilon2000 or the Tecnomanager software for the purpose of troubleshooting (if by this point you still have the will to live) because the box and the product website both suggest the opposite to each other!So in short it's going back to amazon sadly, the PC doesn't detect it, the laptop detects sopmething but it has no idea what and who knows what or where the software is.

Small and Compact and really useful for keeping your critical electronics such as routers and my NAS up and running. It had its first proper test last week when I had some work done on the electrics and the power was out for around 20 minutes. The UPS held up pretty well and kept running. Would happily buy a second one of these.

I was a bit wary of buying this at first, because of the price, but it is surprisingly good. Using to power up a WeeDo - Tina 2 basic printer & accessories. When our power supply gets a bit blippy the printer spits it's dummy out, thus losing the whole print, also does this when plugging / unplugging something as mundane as a phone charger. It worked straight out of the box, is very compact, quiet and only slightly warm in use. I've even unplugged the unit whilst printing and the printer never missed a beat. Within the first hour of use it detected and prevented three transient voltages on the incoming mains, so very pleased with it. And the most important feature is it's value for money. Overall a good bit of kit.

Using to ensure my very fussy Sky Q box doesn't restart every time a sparrow lands on the electric cable somewhere between me and the grid. So far so good including recent hiccups in power supply following Derragh. Now added my fibre modem and main router. Works as advertised. Literally "plug 'n' play". Hopefully internal lead acid battery will last 5 years (as a previous computer UPS did). Nothing fancy, just a stabilised and back-up power supply for electronics that does the job. Not thickest plastic but more than robust enough for household use. Great value for money.

Worked perfectly until it didn't.Battery failed, contacted the manufacturer who were very clear they only provided the extended warranty for EU customers even though that's not made clear at purchase. Told to do a DIY battery replacement, and on opening up the device the battery terminals and cabling were heavily corroded (+ve terminal corroded through).I'll stick to other brands with a UK warranty in future.
