At their most basic, UPS devices are basically sealed lead acid batteries with voltage sensors and their version of an inverter. 12v lead-acid batteries typically cost in the region of £40-£50 alone, so this UPS is cheaper than setting up your own equivalent backup battery.I was fortunate enough to experience several very rare power outages. It switches to backup fairly quickly. The unit does make an incredibly annoying periodic beeping sound when it detects the power has gone out, so don't keep it in any bedrooms. It is possible to disable the beeping sound via an APC utility program (Linux has apcupsd with apctest, for example), but that requires a USB type-B cable, which is not supplied, which is mildly disappointing.It takes a long time to recharge, approximately 5-15 minutes per 1%. That said, during power outage testing, back-of-the-envelope calculations suggest the battery can run a 90W laptop for roughly 3 - 3.5 hours (depleting roughly 7% charge every 15-30 minutes). Although this isn't what UPS is typically used for, it was the purpose it was serving in my case.Unit comes with two plug sockets, however be aware, when the unit is turned on, the more devices plugged into it, the vastly more heat it produces. With no load on, it produced heat comparable to an overly active laptop. With one laptop plugged in, it produced heat equal to a tower PC running on full. With two laptops plugged in, the unit was effectively a radiator. Users in colder climates might want to consider it as a dual-purpose discount heat source.In summer heat, this is a big problem. UPS can only tolerate a very limited range of temperatures, with a particular limit focused on high temperatures, which means this UPS unit contributes to it's own demise. Rooms with it in will either need to be well ventilated with cool air flow, or have a working air-conditioning unit. Alternatively, the unit should be placed in a cooler room. The only other way to reduce heat is to either turn the device off (it will continue to charge but won't power any devices) or to reduce or remove any power loads currently running on it. This is a big problem if you intend to power, say, a desktop PC.It's not entirely clear why it produces so much heat, but if you have a room with already high temperatures, you might want to look for a cooler or more energy efficient unit.Despite the heat issues and beeping, the unit works extremely well, and for it's price, represents good value for money. ### ⭐⭐⭐⭐⭐ Used For A Smart Home *by B***M on 14 June 2019* I have a smart home, with multiple hubs, routers, switches etc, along with a Rapberry Pi to run it all. After a fault toaster tripped the electrics in the building, my smart home was no longer smart. The memory was corrupt on the Raspberry Pi and the whole thing had to be restored from back up. My other concern after this happened was security, as the hubs also run the intruder, fire and flood alarms. I needed a way to keep everything running 24/7, even when the power is out.Fast forwards 24 hours and I order this product, mainly based on it's price/value for money. It also has stadard UK sockets in the back meaning no adapter is required, as many different models only offer the kettle lead type sockets for PC's and monitors.Sadly the first one arrived broken, with a part of the plastic housing smashed into little pieces, all of which were in the box. I do beleive this to be the couriers fault, though. I contacted amazon, who sent out a replacement immediately to arrive the next day. Fantastic service.Installation was super easy, simply plug it into the wall, plug the devices you want to run into the UPS, and turn it on. I left it for a few hours to charge, then went to test it. I simply turned off the wall socket to mimick power failure, you hear a beep to signal the fact it has had to intervene, and everything kept running without a glitch! Great!A week later and the same toaster (that's now in the bin), tripped the buildings electrics. Everything worked exactly as planned! None of the hubs, routers or the Rasperry Pi knew any different. It took me 35 minutes to get home after this happened, and everything was still running even after this time. Please note though, the battery only lasted this long due to the low power consumption of the devices. For use wth a normal PC, monitor etc this will probably be much shorter.A very very happy customer - and would highly reccommend this! Especially for a home network. Considering buying another for the CCTV setup! ### ⭐ Just no hope with it *by F***O on 15 February 2025* We got this as we were getting a lot of storms set it all up as it said one night we had a right bad storm had this crack of thunder everything went of including this.. which it’s not meant to happen it did the same a hour later so sent it back ## Frequently Bought Together - PowerWalker VI Series 850VA/480W Compact Battery backup solution with built-in AVR, HID Supported, Cold (DC) Start Function (Non LCD Screen) - TP-Link LS1008G 8-Port Desktop/Wallmount Gigabit Ethernet Switch/Hub, Ethernet Splitter, Plug & Play, Desktop, Plastic Case - Yauhody CAT 6 Ethernet Cable 1m Ethernet Cable Black 6Pack 1m Network Cable High Speed CAT6 Ethernet Patch Cable 1m Lan Cable CAT6 Gigabit Internet LAN Patch Leads for TV Gaming Router(1m 6Pack Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/67895515-powerwalker-ups-vi-series-850va-480w-compact-battery-backup-solution](https://www.desertcart.pl/products/67895515-powerwalker-ups-vi-series-850va-480w-compact-battery-backup-solution) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-24*
