The best UPS units, compared.
Top pick: Votespo ADR2P mini UPS Best value: Tecnoware ERA PLUS mini UPS – Lowest price in this set at about £30.92, with 4.4 from 160 reviews and a five-year listing warranty. Score 80. UK reviews describe a two-pin or figure-8 lead. Updated October 2026.
A UPS, or uninterruptible power supply, keeps a chosen load running for minutes or a few hours when UK mains fails. The usual jobs are a full-fibre ONT and router, a desktop or NAS. Judge a unit by watts rather than the VA badge. In this class a 1000 VA listing is often 550 W or 600 W, not 1000 W. A mini DC brick suits a router, an ONT or a camera and has no AC waveform. The barrel tip and the amp rating must match the adapter. A mains UPS is for UK plugs and PC supplies. A brick of a few tens of watts will not run a desktop. Only battery-backed sockets stay up in a cut. A lead for a BS 1363 socket should be a correct UK plug, or a compliant converted plug with a BS 1362 fuse. Simulated sine is common on battery. Active power-factor correction is the usual reason to look for pure sine and to test under load. Class, outlets and the plug are set out in the [UPS buying guide](/hub/electrical-equipment/ups/sub/ups-buying-guide).

Personal buying guide
Question 1 of 2
What must stay up?
The Votespo ADR2P lists an 18000 mAh replaceable battery and a front digital display at about £65.99. The star line is 5.0 from only two UK reviews, both positive, which is too small a sample to treat as a pattern. The page claims 5 V, 9 V, 12 V, PoE 15 V and 24 V, plus USB and USB-C at 5 V up to 3.6 A shared, but it does not state a wattage. Runtime is also missing. One reviewer says you still have to match voltage and connector. Warranty is one year, and the manufacturer line is Shenzhen JueQi Technology Co., Ltd. A perfect score on two reviews does not outrank 4.1 from 547.
Pros
Cons
Best for: A DC device whose voltage is on the claimed list, if you accept two reviews and will check the live page.
Less suitable: Anyone ranking by stars alone, or a load that needs a stated watt ceiling before you pay.
Specifications
Common questions
Does the Votespo unit show battery level?
Yes. The listing and both saved UK reviews describe a front digital display of battery and voltage information.
Is the battery described as replaceable?
Yes. The title and bullets call it a replaceable, detachable battery. Capacity on the listing is 18000 mAh.
How many UK reviews are saved?
Two. Both are positive. That is too small a sample to treat the 5.0 score as a strong pattern. One reviewer says you still have to match voltage and connector.
The Ubiquiti UniFi UPS-Tower lists 1000 VA and 600 W at about £199, line-interactive, with ten IEC C13 outlets. Five are battery-backed and five are surge only. The star line is 5.0 from one review, and no review text is saved, so that score is a single tick rather than a pattern. Bullets say it is adopted in a UniFi Network controller, which shows battery status, charge and remaining life, and shutdown is named for a UNVR or UNAS. A hot-swap lead-acid battery is claimed, one 12 V pack, and the unit weighs 8.17 kg. Waveform, runtime, UK sockets and warranty are all unstated. It belongs with a UniFi cupboard that already uses IEC leads, and one star should not decide the comparison.
Pros
Cons
Best for: A UniFi cupboard with IEC leads, where controller battery status matters more than a review history.
Less suitable: A first UPS for a home PC, or anyone treating one five-star rating as proof.
Specifications
Common questions
How is this Ubiquiti UPS monitored?
The saved bullets say it is adopted in a UniFi Network controller, which shows battery status, charge and remaining life.
Which outlets are battery-backed?
The listing says ten IEC C13 outlets, five with battery backup and surge protection and five with surge protection only.
Are there UK reviews in the saved listing?
No review text is saved. The listing line is 5.0 from 1 review. Shutdown features named on the page are for UniFi devices such as UNVR or UNAS.
The Eaton 3P Ellipse 3P700I is an offline tower at about £118.61, listed as 700 VA and 420 W at 230 V, with a stated runtime of 22 minutes and noise under 25 dB. The electronics warranty is three years and the battery warranty is two years, longer than most lines here. The star line is 4.5 from two reviews. The one saved UK review uses it for a fibre ONT, a router and a cordless base, and the reviewer thinks that load would last about an hour. Outlets are IEC C13, not BS 1363, and the title’s outlet count disagrees with the outlet-count field. Weight is 3.7 kg on the specification line and 4.3 kg in a bullet. UK sockets are not stated, so this is not a wall-wart UPS unless you add IEC leads.
Pros
Cons
Best for: Quiet IEC kit around a few hundred watts when a longer electronics warranty matters more than a UK socket.
Less suitable: Several BS 1363 wall adapters, or a buyer who needs more than two reviews.
Specifications
Common questions
Does the Eaton 3P700I have UK sockets?
The saved listing describes IEC C13 outlets, not BS 1363 sockets. The title says four IEC C13 outlets plus four surge-only outlets, while the outlet-count field says 4.
What power is stated?
700 VA and 420 W, offline topology, 230 V, with a listed runtime of 22 minutes.
What does the UK review say?
The one saved UK review uses it for a fibre ONT, a router and a cordless base, and the reviewer thinks that load would last about an hour. There is no fault in that review. The listing count is 2.
The Tecnoware ERA PLUS is the lowest price in this folder at about £30.92, listed as 25 W with 5 V, 9 V, 12 V, 15 V and 20 V outputs, USB-C, USB-A and four tips. It scores 4.4 from 160 reviews, and the listing warranty is five years. UK reviews describe a two-pin or figure-8 mains lead, not a BS 1363 plug, and one reviewer says a figure-8 lead is needed in the UK. The runtime line is up to 240 minutes, which is a ceiling, on a 5200 mAh lithium battery. One UK review says the batteries are easy to replace, which is a comment rather than a fitting guide. The page also lists 1 kg against a 7 x 9 x 3 cm dimension line, so those two figures need a check before you trust the size. It is the best value here on price and stars if you can feed the lead lawfully, and a poor buy if you expected a fused UK plug in the box.
Pros
Cons
Best for: A small DC load under 25 W when you already have a figure-8 lead and will match the voltage.
Less suitable: A buyer who will only use a BS 1363 lead, or a PC.
Specifications
Common questions
Does the Tecnoware ERA PLUS use a UK plug?
UK reviews on the saved page describe a two-pin or figure-8 mains lead, not a BS 1363 plug. One reviewer says a figure-8 lead is needed in the UK.
What DC outputs are listed?
The title lists 5 V, 9 V, 12 V, 15 V and 20 V at 25 W, with USB-C, USB-A and four tips.
Are the batteries described as replaceable?
One UK review says the batteries are easy to replace. That is a review statement, not a step-by-step guide on the listing.
The Powercool 2U rack UPS is listed at about £136.03 as 850 VA and 510 W in a 438 x 88 x 312 mm chassis, with a type G UK plug included. Outputs are one UK socket and three IEC C13 outlets, and the topology line is off-line with AVR. The star line is 4.3 from 16 reviews. Bullets say a typical 15 to 20 minutes from a 12 V 8 Ah battery. A separate specification line says 720 W, and another says 850 V, so use 510 W from the title and do not average those conflicts. Warranty is 12 months, shorter than the two-year lines on several towers here. Noise is stated as under 45 dB. It fits a cupboard rack if you can live with one UK socket and a thin review sample.
Pros
Cons
Best for: A small rack or cupboard where you want a UK plug and one BS 1363 outlet beside IEC kit.
Less suitable: Several UK wall-warts at once, or a buyer who needs one unambiguous watt figure.
Specifications
Common questions
Will this rack UPS plug into a UK socket?
The saved listing says power plug type G and that a UK input plug is included. Outputs are one UK socket and three IEC C13 outlets.
Which watt figure should you use?
The title and the feature bullets say 850 VA and 510 W. A separate specification line says 720 W. Both are on the raw page, so the comparison uses 510 W from the title.
What runtime is stated?
The bullets say a typical 15 to 20 minutes from a 12 V 8 Ah battery, depending on load.
The Powercool 1000 VA unit is a line-interactive tower listed at about £85.75 with 1000 VA and 600 W, three UK sockets and three IEC outlets. The star line is 4.3, but only from 7 reviews, so the rating is thin next to DC bricks with hundreds of ratings. The listing says a typical 15 to 20 minutes from two 12 V 7 Ah sealed lead-acid batteries, a transfer of 6 ms or less, and USB monitoring. Waveform is not confirmed, because the raw bullet cuts off before a pure-sine claim is complete. At 10.9 kg it is a floor or shelf unit, not a mini brick. It is the clearest UK-socket AC option in this folder if you accept a small review sample and an unstated wave.
Pros
Cons
Best for: A small PC, router wall-warts, or a NAS when you want BS 1363 outlets and can live with seven reviews.
Less suitable: An active-PFC PC until the waveform is confirmed, or a buyer who needs a large review sample.
Specifications
Common questions
Does this Powercool UPS have UK sockets?
Yes. The saved listing states three UK sockets and three IEC outlets.
What battery runtime is stated?
The listing says a typical 15 to 20 minutes, depending on load, from two 12 V 7 Ah sealed lead-acid batteries.
Is the waveform stated as pure sine?
No. The raw bullet cuts off before the word is complete, so the saved listing leaves the waveform unconfirmed.
The APC Back-UPS Connect CP12036LI is a 12 V DC, 36 W lithium mini UPS listed at about £57.39, and it sits between an existing router adapter and a barrel tip rather than feeding a PC. Across 547 amazon.co.uk reviews the line is 4.1, the largest sample in this folder. The listing states up to 4 hours and a 12-hour charge, but UK reviews describe shorter runs, including about 30 minutes on a router, so treat four hours as a ceiling. The box is the UPS itself: reviewers say the router power supply is not included. Two dimension lines appear on the saved page, 10.9 x 9.9 x 2.5 cm and 15 x 15 x 2.5 cm, so measure the shelf before you trust either. It is the top pick here for a stated 12 V, 36 W network load with a deep review sample, and it will not run a desktop.
Pros
Cons
Best for: A 12 V router or similar low-voltage box when you already have the adapter and a matching tip.
Less suitable: A desktop, a NAS, or any kit that needs a BS 1363 socket and more than 36 W.
Specifications
Common questions
Does this APC mini UPS have UK mains sockets?
No. The saved listing is a 12 V DC, 36 W unit with barrel tips and the plug type set to no plug. It does not provide BS 1363 outlets.
Is a power supply included?
The box line is the UPS itself. UK reviews on the saved page say the router power supply is not in the box and that you use an existing 12 V adapter.
What runtime does the listing state?
The listing states up to 4 hours. That figure is load-dependent. Some UK reviews describe shorter runs, including about 30 minutes on a router.
The APC Back-UPS BK500EI is listed at about £138.97 as 500 VA and 300 W at 230 V, 50 Hz, with four IEC C13 outlets. Three outlets are battery-backed and one is surge only, and the mains plug on the listing is type F, a two-pin European lead. It scores 4.1 from 136 reviews. The specification line says 2 hours, while UK reviews describe shorter cuts, including about 10 minutes with spare capacity and one report of about 40 minutes. USB shutdown software and a USB cable are in the box contents, which matters if a small PC must close itself. A second dimension line is 42 x 24 x 19 cm against 40.6 x 24.1 x 23.6 cm. You still need IEC leads and a lawful way to connect a type F plug on UK mains.
Pros
Cons
Best for: IEC-cabled kit around 300 W when you already have a safe way to connect a type F lead.
Less suitable: UK wall-warts, or a load that needs the two-hour figure at face value.
Specifications
Common questions
Does the BK500EI have UK sockets?
No. The saved listing states four IEC C13 outlets, three with battery backup and one surge only, and a type F two-pin plug.
Is a USB shutdown cable listed?
Yes. The bullet contents name a USB cable and shutdown software, plus the user manual.
What runtime is on the listing?
The specification line says 2 hours. UK reviews describe shorter real cuts, including about 10 minutes with spare capacity and one report of about 40 minutes.
The SKE DC10400 Pro is listed at about £46.99 as an 18 W, 10400 mAh mini UPS with 9 V and 12 V ports at 2 A, plus USB at 5 V / 2 A. It scores 4.0 from 236 reviews. One UK review reports about 2.5 hours for a fibre modem at about 4 W plus a router at about 14 W, close to that 18 W ceiling, while the listing runtime line is 2 hours. Saved reviews say the leads do not fit a BT Smart Hub, and a Sky SR203 needed a separate 4.75 x 1.7 mm adapter, though a Vodafone Power Hub worked for one reviewer without an extra tip. A listing line says 230 V while the bullets are low-voltage DC, so this is not a mains UPS. Warranty on the page is one year.
Pros
Cons
Best for: A light 9 V or 12 V modem and router that together stay under 18 W and accept the supplied tips.
Less suitable: A BT Smart Hub or Sky SR203 unless you already own the right adapter, or any mains appliance.
Specifications
Common questions
Will the supplied leads fit a BT or Sky hub?
Not always. Saved UK reviews say the leads do not fit a BT Smart Hub, and that a Sky SR203 needed a separate 4.75 x 1.7 mm adapter. A Vodafone Power Hub worked for one reviewer without an extra tip.
What output power does the listing state?
18 W, with 9 V and 12 V DC ports rated 2 A and a USB port at 5 V / 2 A.
How long did reviewers keep a router running?
One saved UK review reports about 2.5 hours for a fibre modem at about 4 W plus a router at about 14 W. The listing runtime line is 2 hours.
The CyberPower VP1000EILCD is a line-interactive tower at about £166.99, listed as 1000 VA and 550 W at 230 V, with simulated sine wave output, AVR and an LCD. It scores 4.0 from 72 reviews. Six IEC outlets are listed, and UK 13 A sockets are not stated. The listing runtime is 9 minutes. Reviewers name Synology models that shut down from the UPS, and also a case where the unit did not hold a NAS when mains failed, so a shutdown signal is not the same as staying up. The waveform is explicit here, unlike pages that cut the sine claim off, which means you should not assume pure sine for an active-PFC PC. At 6.2 kg and 34 x 31 x 15 cm it is a shelf tower that expects IEC leads.
Pros
Cons
Best for: IEC equipment that tolerates simulated sine, including a NAS you will test for shutdown, within about 550 W.
Less suitable: An active-PFC PC supply, or wall-warts that need BS 1363 sockets.
Specifications
Common questions
Is the CyberPower VP1000EILCD pure sine?
No. The saved listing states simulated sine wave output, with line-interactive topology and AVR.
How many outlets does it list?
Six IEC outlets. UK 13 A sockets are not stated.
Do UK reviews mention a NAS?
Yes. Reviewers name Synology models that shut down from the UPS, and also a case where the unit did not hold a NAS when mains failed. The listing runtime is 9 minutes.
The Eaton 3S Mini 3SM36B lists 9 V, 12 V, 15 V and 19 V at 36 W for about £53.99, with four barrel tips, so one brick covers more voltages than a 12 V-only unit. The star line is 3.6 from 190 reviews, the weakest large sample among the DC bricks here. UK reviews repeat batteries failing at about two years, including just after the two-year warranty. The lead is described as about one metre, which is short if the hub sits across the room from the socket. Dimension lines on the page do not match each other exactly. Selectable voltage helps only if you set it to the adapter label before you connect the tip.
Pros
Cons
Best for: A low-voltage router or camera on 9, 12, 15 or 19 V when the socket is within about a metre.
Less suitable: A multi-year fit-and-forget battery, or a PC that needs a 13 A plug.
Specifications
Common questions
Which DC voltages does the Eaton 3S Mini list?
The saved listing states 9 V, 12 V, 15 V and 19 V at 36 W, with four barrel tips.
Does it include UK 13 A sockets?
No. It is a DC mini UPS for routers, cameras and similar low-voltage gear.
What do UK reviews say about the battery?
Across the saved UK reviews, batteries failing at about two years, including just after the two-year warranty, is a repeated theme. The lead is also described as about one metre.
The APC Easy UPS BVX2200LI lists 2200 VA and 1200 W at about £203.97, with AVR and a stated runtime of 5 minutes. The amazon.co.uk line is 2.9 from 166 reviews, the lowest stars in this folder. The saved bullet says no UK plug is included, and UK reviews describe a European lead and, for some units, an input that is not a standard IEC kettle inlet. The title says six IEC C19 outlets while the specification connector line says IEC-C13, so you cannot order cables from one line alone. Several reviewers report the unit failing after about 12 to 17 months, against a listing battery-life bullet of 2 to 3 years that was not measured here. A 300 V specification line also appears and should not be read as the output. The watt figure is the largest here, and it is still a poor default for a straight UK socket.
Pros
Cons
Best for: Someone who already has the correct IEC leads and a safe feed for a European input, and who only needs a few minutes.
Less suitable: A straight BS 1363 setup, or anyone choosing from star ratings in this folder.
Specifications
Common questions
Does the APC BVX2200LI come with a UK plug?
The saved listing bullet says no UK plug is included. UK reviews describe a European lead and, for some units, an input that is not a standard IEC kettle inlet.
Are the six outlets C13 or C19?
The title says six IEC C19 outlets. The specification connector line says IEC-C13. Both are kept because the saved page disagrees.
What do the UK reviews repeat?
The plug is the main complaint. Several reviewers also report the unit failing after about 12 to 17 months. The listing score is 2.9 from 166 reviews.
Twelve amazon.co.uk UPS listings were scored from the shelf in files dated 19 October 2026. This is not a lab test. A printed watt rating, runtime or plug type is a listing claim. A DC mini and a mains UPS stay in one table, and a high star line from one or two reviews cannot outrank a lower score from hundreds. No methodology file was supplied, so the weights follow the buying order in the research digest.
Watts, not the VA badge
25%The load that must stay up, in watts. VA is apparent power. In this set a 1000 VA unit is 550 W or 600 W, not 1000 W. A missing watt field lowers this part.
Family
15%A DC mini here is about 18–36 W, for a router, ONT or camera. A mains UPS is for UK plugs and PC supplies. A 36 W brick does not score as a desktop UPS.
Outlets, plug and waveform
25%Battery-backed sockets, a BS 1363 plug or a stated European lead, and the wave on battery. Simulated sine is common. Pure sine is the usual reason to test an active-PFC PC supply. A DC brick has no AC wave.
Runtime and shutdown
15%The stated runtime is a ceiling unless the load is named. USB or vendor shutdown matters if a NAS must close itself. Review notes of much shorter runs lower this part.
Reviews and price for the job
20%The amazon.co.uk star line and review count, read against the shelf price for the job the listing actually supports. A 5.0 from one or two reviews is weaker evidence than a lower score from hundreds.
Start with watts, then the family, then the plug and the wave. Price comes after those. The notes below follow that order for these 12 amazon.co.uk listings, from files dated 19 October 2026. None of the scores is a lab test.
A UPS keeps a chosen load running for minutes or a few hours when UK mains fails, and many models also clamp surges or correct mild voltage drift. On amazon.co.uk the usual jobs are a full-fibre ONT and router, a desktop or NAS, or a small rack of network and CCTV gear. This page compares the 12 listings in the table. Shelf prices are the figures on those amazon.co.uk pages in the files dated 19 October 2026, and they will move. None of the scores is a lab test. Watts come before the VA badge.
VA is apparent power. In this set a 1000 VA unit is 550 W or 600 W, not 1000 W. Add the watts on the device labels, including the ONT as well as the router. A 36 W brick will not run a desktop.
“Up to” hours are a ceiling. The APC mini states up to 4 hours, and some UK reviews report about 30 minutes on a router. Use the runtime at your load, and add USB or vendor shutdown if a NAS must close itself.
IEC-only outlets will not take a UK wall-wart. A European lead, or a listing that states no UK plug, is a buying problem under regulation 35. Backing up the router and leaving the ONT on the wall still drops the connection.
Size the load in watts first. DC minis in the saved price band sit at about £30.92, £46.99, £53.99, £57.39 and £65.99, from 18 W to 36 W, or 25 W where that is the stated ceiling. One DC listing does not state watts at all. Small AC units, about 500–1000 VA, sit at about £85.75, £118.61, £136.03 and £138.97. Larger or managed AC units sit at about £166.99, £199 and £203.97. Standby switches on failure.
Only battery-backed sockets work in a cut. Look for a BS 1363 plug, or a type G lead, if you will use UK wall-warts. A type F plug, a figure-8 lead, or a bullet that says no UK plug is included, means you still have to connect it lawfully. CE or UKCA does not prove the plug is British. On battery, simulated sine is common. Decide whether a stepped wave is acceptable for a PC supply before you buy. DC bricks have no AC wave.
Three typical situations, each with a recommendation from this comparison.
You are keeping a 12 V network box up, and you already have the adapter and a matching tip. The APC Back-UPS Connect CP12036LI is about £57.39, 36 W, with 4.1 from 547 reviews. It has no mains sockets, and four hours on the listing is a ceiling.
You want BS 1363 outlets for a PC, a NAS or wall-warts, and you can live with a thin review file. The Powercool 1000 VA unit is about £85.75, listed as 600 W, with three UK sockets. The waveform is not confirmed on the saved page.
You want a 2U chassis and a UK input plug. The Powercool rack UPS is about £136.03, 510 W on the title, with one UK socket and three IEC C13 outlets. A separate line says 720 W, so use 510 W. The review count is 16.
In this set of 12 amazon.co.uk listings, the top pick is the APC Back-UPS Connect CP12036LI at about £57.39, with 4.1 from 547 reviews and a score of 84. It is a 12 V, 36 W lithium mini UPS, and it will not run a desktop. The best value is the Tecnoware ERA PLUS at about £30.92, with 4.4 from 160 reviews and a score of 80, the lowest price here against a large review count. UK reviews describe a two-pin or figure-8 lead, not a BS 1363 plug. Neither score is a lab test. A 36 W brick does not replace a mains UPS, and a new circuit or a hard-wired bypass is work for an electrician.
Tecnoware ERA PLUS mini UPS
Lowest price in this set at about £30.92, with 4.4 from 160 reviews and a five-year listing warranty. Score 80. UK reviews describe a two-pin or figure-8 lead.
