PowerWalker UPS VI 2200VA/1200W LCD IEC Uninterruptible Power Supply with 6 x IEC C13 Outputs, AVR Stabilizer, RJ-11 Surge Protection, HID Support and LCD Screen

Two year on update Still working but after adding additional load realised I needed to add a second UPS and to split the load. Got a second UPS but a different model, a PowerWalker VI Series 2200VA/1320W, which is even better as it has UK plug and sockets, its also cheaper, smaller and higher spec. One year on update So today powered up the attached devices and the UPS fan kicked in - it is noisy - looking at the Winpower manager software it showed "Output: AVR mode" - hadn't seen that (or the fan running) before - work comes first so I just left it - a couple of hours later the fan stopped - Winpower manager showed "Output: Normal mode" (see picture). You can see the input voltage is 249V - when it was in AVR mode the input voltage was over 250V (upto 254V) - it seems the UPS was protecting devices from over voltage. Made me think the reviews that say the fan run all the time might be due to supply overvoltage. Would buy this model/brand again. Working from home you notice all the power cuts and blips - already had Jackery power stations but they are offline and I still lost work when the mains power fails - got a small APC UPS to power modem, router and 4G backup modem but needed somthing bigger for a large tower pc, its 3 screens, 2 laptops external screens and sundry hubs - this power walker UPS 1200w seemed suitable and very good value - it worked - the windows monitoring sofware reports 18-20% load and a 22-24 minute expected run time - didn't need to test as soon after it was installed there was a power cut - allowed plenty of time to bring the Jackerys online (powering the UPSs) - probably paid for itself first use - can't hear it over the tower pc in standby - makes lots of noise and beeps during a power cut (which is good) and some noise while recharging - front blue lcd display is easy to read but not too bright - And don't forget you also need light in a power cut - keep some rechargeable torches handy

Just wanted to leave a review for the next guy because when setup I had some annoying buzzing. Firstly, the unit powered up straight away and seems to function without issue. Tested turning the plug off at the wall to check it fails over to battery perfectly fine. However, when first powered on - there was a high-pitched buzz. Similar to a coil buzz on a capacitor which came on and off every 5 seconds roughly. Was going to send the unit back as it's in a quiet office but thought I'd just leave it for a few hours. After about 2 hours the buzz completely stopped and it's now silent. So seems to be while charging the battery; I can deal with that for the price of this unit. It's not an APC, but it's good enough for a small home-office. EDIT: The buzzing returned. Every 5 seconds the buzz would be present again. Due to me being in such a quiet office this had to be returned. However, don't be put off if you're buying for a cupboard or server room. It'd work great for that.

I was a little sceptical, given the price, but it's a decent piece of kit. It's saved me countless times when we were having power issues, and gives you enough time to fire off a couple of emails and shut down. It also might be coincidence, but since I've started using this, my PSUs have been lasting years longer (power conditioning?). Maybe not the best idea for a bedroom, as it'll sometimes fire up the fan, presumably to recharge. So if your power dipped for a few seconds at 2am one night, it seems to pick 2am the next night to recharge, and then the next night, and then the next night! The alarm's plenty loud enough, you'll not miss it... and it seems to handle 2 PCs with a screen each + the router. I haven't used any of the USB features, but I have to assume it'll handle shutting down your machine, etc. Overall, great value for money; definitely worth it for the peace of mind!

My old Eaton EX 1500 UPS (which was in excess of 6 years old) recently stopped working properly and, after finding the correct replacement batteries, I was told it could also be a fault with the internal charger responsible for maintaining the batteries. So I started looking for a whole new UPS. I did a few loops of Google, Amazon as well as APC's website (which wasn't enjoyable to use) and, after finding hardly any reviews and definitive information on which UPS to buy on Google or so called 'specialist' websites, I went with this Powerwalker 2200. First impressions are that this UPS is fantastic! In normal mode it's almost totally silent - so if you work in a home office you won't notice it over the usual hum of your computer - which is great, as my old Eaton EX 1500 had a fan that was always on. During normal operation, there's a slight buzzing noise, but it's barely noticeable - it's likely just the internal components managing the input/output voltage as well as being ready to balance the load if there's a power cut. The unit itself is pretty small and unobtrusive, it just weighs quite a bit for its size - which is probably just the weight of the batteries inside. I spent a lot of time looking for a suitable UPS and I'm really happy I chose this one. For the price it's great value, as I'm confident I'll get 30-45mins of run time if we have a power cut (based on another person's review and my initial tests). I'm powering a 24" Dell monitor, a mid-2010 Mac Pro tower and a vinyl cutter used to make stickers. The cold-start feature works well too - simply turn it on and you've got instant access to 240v, without it being turned on at the wall. When you simulate a power cut (turning the UPS off at the wall) the load instantly gets taken up by the UPS with zero latency. An issue with 90-degree UK IEC plugs: If you haven't got one already, you'll need to buy a multi-gang power cable/adaptor as the UPS doesn't come with one, so you won't be able to plug your computer in, etc. Make sure the gang socket cable doesn't have a 90-degree IEC plug, as the cable doesn't clear the ground/surface when it's plugged into the back of the UPS. The IEC cable needs to come straight out of the back of the UPS... hopefully that makes sense? See the photos I've included. Overall, though, If you're on the fence, definitely buy this UPS as it'll cover all of your needs if you need to have an 'insurance policy' for your computer equipment if you have a power cut.

Cheap for a reason, would be the take-home message here. The hardware is probably ok, in fact not bad at all for the price. I assume most of the 'cheap' UPS are similar in terms of their hardware, performance and rating. However, the software supplied with the unit is hopeless! I purchased this UPS specifically to support a small ~100W office server running Linux (Centos7), which the manufacturer's software claims it supports. I installed the x86-64 version from the supplied DVD... and it left the server unbootable! Poking around from the recovery console eventually led me to find the rogue entry it had added to /etc/fstab. Downloaded the latest version from the manufacturer and installed... at least this didn't break the server, however the PowerWalker WinPower software crashes on start-up with various Java exceptions (and yes, I do have the latest Java installed). PowerWalker's customer services were sympathetic but no help in the end. I then tried to get 'nut' to work. nut installs fine, however the UPS appears not to communicate correctly via the blazer_usb driver, which is the recommended interface driver for this unit. I'd wasted enough hours on it by this point so I gave up. I'm returning it to Amazon as not fit for purpose. PowerWalker might be ok for Windows - I can't be sure as I didn't test it - but it's hopeless for Linux. All the servers I administer are Linux, so it's no to PowerWalker from me. Edit: comment added a couple of weeks later... I returned the PowerWalker, Amazon as good as ever on returns. Then, I purchased a Riello 1200VA Sentinel Pro. More expensive, obviously. The Riello seems excellent in comparison, vastly superior interface, software works under Linux (except UPS-Tools, a PC is needed for that, but only if you need to tweak the UPS internal settings... which I did, as the default cut-off is just 3 minutes and I need 10+ minutes warning of battery exhaustion). Five year warranty too, and battery life expectancy of 3-5 years depending on temperature - batteries are exchangeable, and industry standard format. Five stars (by proxy) for Riello.

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."

I was experiencing some issues with my home electricity supply. Working from home, the intermittent power cuts were causing me a lot of inconvenience. The UPS was easy to set up (although the software interface is a little 'clunky'). I have a workstation, 2 monitors, a NAS, and a router plugged in. On loss of power supply, the UPS kicks in immediately - to the point there is absolutely no interruption or hint of disruption. The supply lasts for approx 40mins running the above devices - which for me, is more than enough time to restore the power supply, or would be sufficinent to safely save any open work and shut down. Some reviews have mentioned noise - it is noisy when running in a power-loss situation, and is noisy when re-charging (or performing the initial charge)... there is an audible fan sound... but that is fine for me - and it is silent when in normal operation. The onboard display provides information about charge level and voltage levels, and the software side provides information on current set up / operation, and also logs events, with the option to email on selected events. Should have got one years ago!

Plug in and turn it on about as easy as it gets. Software is another matter, make sure you use the serial number in the quick start guide not the UPS serial number. Connection between the software and computer is flaky with it loosing connection. As a stand alone UPS though it's fine. The BIG issue - the fan doesn't turn off and it's noisy. Very distracting in an office environment. Thought there might by a way to turn them off or down very in the software but no. I've got 3 APC UPS and they are silent most of the time. If it hadn't been stored away in its box beyond the return date I would have returned it. Edit - Added a Star, seems it didn't like the hot weather. The fan does turn off and it is silent, but when running it is still overly noisy and annoying. So, OK for a noisy office environment.
