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

A well-made product, feels solid with no cheap corner cutting. Easy to set up. I did have one problem accessing the menu to turn off the audible beep which comes on every 10s during power cuts. I emailed the support address listed on the website and got quick friendly and professional replies from a team in Germany. The sort of support you don't get often these days - real people with real email addresses cc:ing each other on the problem, not "type between the lines" and some clown will come back to you reading a troubleshooting list out. I am using it for the home TV/DVR area as we get a few power cuts in the winter and the kids go mental. I tested it by switching off the mains sockets and the system doesn't blink. The fan fires up a little bit noisy but not too bad and there is no loss to the viewing. I might get another one for the fridge/freezer! Add-on: 2017. I have three of these now. I am a bit disappointed with the battery life when not used much. I have had very few interruptions and the newest one has had no interruptions, but the fan now stays on permanently. The battery seems to get worn out quite quickly for something not used much. Shouldn't they last more than 2 years of very light usage? The replacement batteries are quite expensive. I now think I will simply get a Generator as we have fewer power cuts than we used to and the utility of this device is now reduced for me.

It's an OK UPS but some times it seems to fire itself up when not in use. I did some decorating and turned it off and moved it out of the room to do the decorating. To my surprise a few hours later, I heard the fans of this thing kick in as if it were under load and getting hot. Yet nothing was plugged into and it was turned off ?! But I've now been using it for over a year without a problem and it manages to power my Intel Atom NAS box and all my switches. Living in the countryside we often get power cuts and I don't want my NAS box dying or killing a hard disk during a power cut and so I think this thing has saved me from data loss. It's not a particularly big box, and surprising at 1100W and it manages to power my intel atom box for about 4 hours when idle before it gives up and turns off. My atom box only uses 40W of power when idle though. The UPS has a USB socket for connecting up to the computer to shut it down, but I never managed to get the software to work. It says it supports linux and windows and I'm using Ubuntu linux and I managed to get the software installed but couldn't get it to work (admittedly I only put about an hour of effort into it) but I think id rather try some open source NUT alternative software

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!

Ese producto ha tardado unos 3 semanas en llegar. Cuando abrí la caja de Amazon encontré el embalaje original pero con el sello de seguridad cortado. Dentro el poliestireno era roto y muy poco útil y el SAI no funcionaba. Soy técnico entonces abro la caja y encontrado dos soportes rotos y la batería con un cable suelto. Repare y ya funciona. Por el tiempo que ha tardado en llegar no devolví el producto. Solo lo uso por la compatibilidad con el NAS de Synology.
