PowerWalker VI 600 SW/UK 360W Pure Sine Wave IEC UPS

The media could not be loaded. The polarity on the IEC output sockets is swapped from the polarity at the input.Do not use this UPS in conjunction with an IEC to BS1363 socket adapter without first using a socket tester to confirm that the output polarity is correct.A single pole relay which disconnects the output leaving live connected! A switched neutral connection is a serious safety flaw if one of these UPSes is used in conjunction with a commonly available IEC to BS1363 socket adapter. As IEC connectors are not guaranteed to have a fixed polarity, or may be used in split-phase countries with two live conductors, a double pole relay should be used so that both phases are disconnected when the unit is switched off. While it is not officially specified, all IEC connectors with BS1363 plugs have the same live/neutral layout - and the only one which is being switched in this UPS is the neutral connection.The swapped polarity on the output is caused by incorrect wiring to the IEC input connector. Pictures are attached of the left/bottom male IEC pin being incorrectly connected to a blue/neutral wire inside the unit.I have contacted PowerWalker support looking for more information on whether this is this a design flaw common to all of these UPSes, or an assembly failure specific to my unit.

This is a short review/warning for the 2200VA IEC/UK model.So, unfortunately I have nothing good to say about this product.For the price of almost half of what competing brands charge you think you're getting yourself a great deal, unfortunately you're not.So, I unpacked the unit which was reasonably well protected with about 40mm thick polystyrene around the front & back ends.Comes with useful documentation too.That's about the only good I can say about it.Firstly, it came equipped with a 10A fused plug.... Why? It should be fused to 13A...Anyway that's not the worst of it.This thing is awful in regards to onboard temperature management.Basically I plugged it in to charge up it's batteries only to find they were fully charged, "That's Nice." I thought to myself, and for the next 45 minutes it just sat in the corner of my room making no noise and not doing anything, I didn't ever connect any items to it's output sockets so it was only ever able to charge itself, it never got used at all.And this is where stuff hit the fan.... Not literally, but kind of ironic wording on my part, because the fan on this thing is the primary fault of the product. After being switched on and doing nothing at all for 45 minutes the fan switched itself on, I thought this was every strange so I put my hand at the back of the unit to feel the heat from the air the fan was drawing through, it was Ice cold, in fact it was probably cooler than it was when I got it out og the box.....So I left the fan for 15 minutes hoping it would switch off, but, it never did, 1 hour later it was still going.....And it would seem that according to another review on Amazon about the 2200VA IEC/UK model this is a design fault.Basically if your voltage on the input goes above 252V even for a split second the fan will kick in and it won't ever stop until you pull power to the UPS itself from the wall and make sure it isn't powering anything with it's battery.252V is within the UK Electrical Spec for a +10% / -6% of voltage fluctuation that all products must work within, clearly this unit is built so cheaply that it can't even meet that minimum requirement, which for the majority of homes in the UK makes this product unfit for purpose.So in the end, I am returning it as we speak for a full refund, and frankly I am never buying from this brand again.If you live in the UK, and are thinking of getting the 2200VA model for your needs, don't bother, go and buy a different model from another brand, it will cost you more intially but will actually work when you need it to, and function as it should do.As the old saying goes;"Buy Cheap, Buy Twice."

Excellent.This review is regarding the 650SE LCD model.Further to a previous review with IEC to BS standard plug adapters having reverse polarity on live and neutral, I can confirm that this issue seems to have been resolved as shown in the attached image. Oddly, the earth disconnects when running on battery, but I am guessing this is a design feature.This UPS is working fine connected by USB to my Synology DS215j NAS and is also powering a BT Smart Hub and BT cordless telephone and the Synology NAS reports a battery run time of an hour on battery.

Been running with out any problems at all. Then it was time to put a new battery in I was quite shocked when I opened the unit. The live wire was trapped by the screw fixing and was so bad it looks like the screw went throw the wire. This is the first time I have opened the unit so it was defiantly done when it was built. I have done electronics in the past so I can say who ever did it should of felt there was something in the way. So clearly they have staff that don't care at all what they are doing. So will never buy again as they clearly don't have any quality control in place.

The AVR function makes this unusable for . It kicks in at around 250V and then stays active when the supply drops below this value. Whiles it is active the output drops to around 215V.What this means in practice is:I switch the UPS onI switch my PC onIt works fine for a while (+- 1/2 - 1 hour or so)The supply goes above 252V.Unit switches to battery powered AVR mode. Fan kicks in (which is too loud for continuous use in my quiet office).Output drops to ~215VSupply goes below 250VUnit stays in AVR modeFan is annoyingI switch my system offSwitch off UPSSwitch off the supply to the UPS at the wallRestart the UPSEverything is fineRinseRepeatIf your supply goes above 250V (UK spec is 230V +10% -6% I believe) you may experience similar issues. Be careful
