Customer Review

on 16 March 2012
NOTE - see end - initial rating was 5-star but now downgraded to 2-star - get APC's instead!

I had 3 of the (very small and very cheap) APC small UPS devices but none of them lasted very long (2 years or so) even with new batteries purchased, and didn't last very long in supplying power during power loss either - less than 5 minutes! I bought a Trust 650VA UPS about 4 years ago and found it was much better, supplying power for over 15 minutes - and it was cheaper than the APC! A downside was that the Trust has kettle-type mains sockets for its output - it is designed to be used for desktop PC's with that type of input socket on the system unit and monitor. I wanted more flexibility - normal-looking 13a mains sockets for me please (albeit labelled up so you don't plug a 3kw heater into it!). No big problem - cut the other end off the Trust-supplied lead, take a 4-way mains adaptor apart and remove its cable and connect the butchered Trust cable in instead. (If you are not familiar with mains electrics get someone you trust(!) to do this for you.)

Having done that - it worked great for about 3 years but then I got a new computer. In common Microsoft tradition, less than half of the software I had on my old machine (XP) worked on the new machine (Windows 7)! So - I needed to be able to have both PC's running at the same time, plus my TiVo and Panasonic BWT700 plus my Tosh VHS/HDD/DVD recorder (anything with a hard disk drive should ideally be supplied via a UPS IMHO). Unfortunately all this lot was too much for the 650 VA UPS and it started beeping at me in pain! (It didn't cut out or anything - just a warning.) So I bought a 1000VA Trust UPS. Superb! My adapted 4-way mains socket of course still works, I now have enough power for all my stuff and in at least 5 subsequent power outages (we have an over-sensitive circuit-breaker system as well as the street mains supply going out at least once per annum) it supplied power for over 20 minutes - plenty of time for me to reset the circuit-breaker or to shut down the kit etc.

So - well pleased - in fact I'm just about to buy another one for another room ...

BUT - that was then (2013) - this is now (July 2017)

I got a 1000VA Trust UPS in 2013 as I had reasonably good experience of 5 of the smaller models - however looking at them in hindsight ...

1 I was a bit worried that they run somewhat warm - even when carefully placed so that the airflow vents are not covered ...
2 The necessity for wiring up a 13A socket strip is annoying ...
3 The installation of the battery process is decidedly fiddly - 8 small screws to be undone and replaced carefully - and it is VERY easy to drop a small screw into the internals which could well cause major problems ...and the battery holding cage is very flimsy ...
4 I had significant problems with my Freeview Aerial setup with my Panasonic BWT series recorders - interference made several machines virtually unusable. Most of them I fixed with better aerial interconnect leads (best surprisingly were from B&Q - "Smartwares Pro Series Ultra High Performance Aerial Cable" - Those cured most of the problems in most cases). However after much further investigation I found that the TRUST UPS units actually produced interference themselves - moving aerial leads well away from them (over 1 metre) improved the situation noticeably!

4 However the kicker was when we went on holiday the main 1000VA UPS cut out for no known reason (none of the others cut out at all) - and it crashed the hard drive on one of my Panasonic Hard Disk Recorders! I know there was no actual mains disconnection as we have circuit breakers and none had tripped! However one of the recorders (fortunately only one!) was actually recording a TV programme when the UPS cut out - and the disk drive heads crashed into the disk surface! I had major hassles when I got back with the machine trying to start up and finding further errors - I eventually ended up reformatted the HDD (Hard Disk Drive) disk (losing all my programmes of course) but I am still having problems with that machine - it has just crashed again today! (And again - 4 times on 30th July!)
I wouldn't mind but it's a 400 squids machine ...

But - the best is yet to come ...

Still persevering with the TRUST UPS - I opened it up and tested the battery - it was only producing about 4 volts instead of 12 plus!

Aha ...

Hmm ...

To be fair - we had had multiple cutoffs over the last 4 years or so due to the improperly installed Circuit Breakers that they insist you install these days - fuseboxes are nowadays a no-no as people tended to put too high a rating fuse wire in them which can cause fires ...

When these UPS devices have to run on the battery it takes a lot out of them - the idea is that you switch the circuit breakers back on again within the 20 minutes the UPS gives you. However if you're out - or on holiday - it probably just runs virtually flat!

Have sympathy for your poor UPS Battery!

Thinking the problem was simply a dead battery I bought a new one ...

Oh yes - over 12 volts - raring to go ...

But when I fitted it into the UPS and pressed the on button - smoke immediately started pouring out of the UPS - and I could see it was on fire inside through the air vents!!!!

I have never moved so fast in my life - unplugging inputs and outputs - picking the darn thing up and running downstairs - screaming at the wife to keep the dogs locked up in the lounge - and throwing it on the garden grass where it continued to smoke ...Taking my life in my hands I turned the darn thing upside down and swiftly opened it up and disconnected that new battery! Whew - OK now - except for the stink of burning and blackened insides! The transformer looked like it had almost melted!

It is possible that the plastic frame and screws which hold the battery in place (which are pathetically flimsy - I had a new one arrive with the case broken by the battery shifting in transit) may have caused the problem - fitting the battery and connecting it up is actually a bit of a nightmare and it is possible to drop one of the very small and fiddly screws into the works - possibly causing a short circuit ...?

My wife immediately threw a fit and demanded that I remove these from the house! I didn't argue!

Replaced with the APC flat slab style UPS's - delighted that they run stone cold (the TRUSTS ran uncomfortably hot even with a light load) and they have British Standard 13 Amp sockets - 4 off fully UPS protected (rest just surge protected). Oh - and my aerial interference problems seem to have disappeared ...!!!!

Oh - and the battery compartment is nicely designed and requires no flimsy screws to be used - the compartment just slides open and you connect the second lead to the battery and you are in business! Lovely bit of careful design compared with UKNOWHO!!

Reducing from 5 star (why was I so generous?) to 2-star because of the above.

To be fair - the TRUST UPS devices actually worked passably well for 3 years or so - they did protect my devices from many cutouts when our Mains circuit breakers were unbalanced and kept on cutting out - that problem was fixed by a competent electrician last year.

However the questionable design and build problems - especially when it caught fire - that was the end of the argument - gotta go!

Never again - I do not TRUST these boxes!

Sorry if I misled anyone with that early version of this review back when I knew nothing !!

Be Warned - any review written when the item is just purchased is bound to be a "Rose-coloured spectacles" opinion. Faults are more likely to appear later ...
