Best Portable Power Stations for UK Home Backup (2026)

A research-led roundup of four portable power stations for UK home backup, combining manufacturer specifications with attributed independent reviews.

By FoxVerdict Editors, Editorial Team18 min read

Introduction

A portable power station is a rechargeable battery with built-in mains sockets. For UK home backup it can keep essentials such as a router, lights, phone chargers and a laptop running through a power cut, and many models can also be topped up from solar panels.

This roundup covers four units of roughly 750 to 1,100 Wh. It does not rank them by FoxVerdict test results, because none were run. It collects what the manufacturers specify and what independent reviewers report, shows where they agree and disagree, and explains how to match a unit to the devices you would actually need to keep running.

Quick verdict

FoxVerdict editorial view

  • Quiet backup for a router, lighting, laptop or home office

    BLUETTI AC70 (UK plug)

    It is the lightest and most compact of the four, and the only one with a UK reviewer's measured energy delivery at several different loads (about 643 to 697 Wh from 768 Wh). That reviewer found it quiet and quick to switch over, but its sample made an intermittent high-pitched noise at light AC loads, which may be noticeable in a quiet room, and the reviewer judged its 1,000 W limit and modest storage too little for demanding home loads. Choose it for light loads, not for heating or kitchen appliances.

  • A mid-size unit with UK sockets and a tested switchover

    BLUETTI Elite 100 V2 (UK plug)

    It combines 1,024 Wh and an 1,800 W rating with UK sockets, and has measured usable energy of about 890 Wh from a purchased unit (variant not stated, but its 15 A rating and US prices point to a US 120 V model) and a UK reviewer's switchover test. One reviewer found it slow to recharge, reviewers differ on how loud it gets at high output, and it has only two AC sockets.

  • The most stored energy for the weight and size

    Jackery Explorer 1000 v2

    On manufacturer figures it stores the most energy per kilogram of the four (1,070 Wh at 10.8 kg). A US review measured about 87.5% efficiency at a near-maximum load. Its solar input is capped at 400 W, it cannot be expanded, and the measurements found were not made on the UK model.

  • A system that can grow with extra batteries and solar panels

    EcoFlow DELTA 3 Plus

    EcoFlow lists expansion to 5 kWh, which none of the others offers, and a 1,000 W combined solar input (two 500 W ports) that the Elite 100 V2 also lists. It is conditional: reviewers disagree about its cooling-fan behaviour, no fix was confirmed, and the measurements found come from US units.

Product summaries

BLUETTI

BLUETTI AC70 (UK plug)

FoxVerdict editorial view

A compact 10.2 kg unit with a 1,000 W AC limit. Independent measurements put usable energy at roughly 640 to 700 Wh depending on the load. The one UK review found it quiet and quick to switch to battery, and judged its output and storage a little short for demanding home backup but well suited to a home office or a medical device. It suits router, lighting and laptop loads better than kettles, heaters or larger appliances.

Worth checking

  • AC output is limited to 1,000 W. A power lifting mode runs some simple resistive heating loads at reduced voltage, and a UK reviewer recorded the supply dropping to 182 V in that mode, so it is not suitable for electronics.
  • The UK reviewer's sample made an intermittent high-pitched noise from the AC outlets at low loads; whether this is common is not established.
  • The manufacturer's own page gives different mains charging figures in different places (950 W and 850 W).
  • The unit has no built-in light, and the UK reviewer found the two stacked UK sockets awkward for bulky plugs.

BLUETTI

BLUETTI Elite 100 V2 (UK plug)

FoxVerdict editorial view

A 1,024 Wh, 11.5 kg unit with an 1,800 W AC rating across two UK sockets and a stated 1,000 W solar input. OutdoorGearLab, which says it buys the products it tests, measured about 890 Wh delivered (87% of the rating), and a UK reviewer at TechRadar kept an office set-up running through a simulated mains cut. One reviewer found it slow to recharge, and reviewers differ on how loud it gets at high output.

Worth checking

  • The UK version has only two AC sockets, which TechRadar lists among its drawbacks.
  • OutdoorGearLab measured about two hours to recharge from empty, which it called slow against rivals, while Bluetti's page states 45 minutes to 80% and 70 minutes to full with its 1,200 W AC TurboBoost charging. The review also notes an app turbo mode and says using it regularly may shorten battery life.
  • Bluetti's quoted noise level of under 30 dB applies only in a silent mode limited to 600 W, according to Notebookcheck, which found the unit noticeably louder at full output.
  • The capacity and efficiency measurements come from units whose variant is not stated or is US 120 V. The only UK-model review read, from TechRadar, did not measure capacity.
  • Its 2,700 W power lifting mode is a temporary, reduced-voltage mode rather than a continuous rating; The Solar Lab saw a brief spike to 3,200 W on a US unit.

Jackery

Jackery Explorer 1000 v2

FoxVerdict editorial view

A 1,070 Wh, 10.8 kg unit with 1,500 W rated output and the most stored energy per kilogram of the four on manufacturer figures. A US review reported about 87.5% efficiency at a near-maximum load and a mains recharge of around an hour and a half. A UK review recorded its 100 W panel peaking at 76 W in hazy sun and gaining little on a cloudy day. Solar input is capped at 400 W and capacity cannot be expanded.

Worth checking

  • The measurements found were made on a unit with US 120 V outlets and have not been repeated on the UK model by any source found.
  • A UK reviewer's 1.8 kW heater setting cut out after about 10 seconds, as expected for a 1,500 W rating.
  • A US reviewer reported that Jackery's marketing material lists 600 W of solar input with six panels, while the unit itself and Jackery's UK specification table give a 400 W maximum.
  • Jackery's UK page lists a 3-year standard warranty plus a 2-year extended warranty, and says the warranty applies only to purchases from the official Jackery website, Jackery-branded third-party platforms or local authorised dealers, so check that the seller qualifies.

5 independent findings from The Solar Lab and T3Where to buy

EcoFlow

EcoFlow DELTA 3 Plus

FoxVerdict editorial view

A 1,024 Wh unit with four 1,800 W sockets, a stated 1,000 W combined solar input and optional expansion to 5 kWh. A US review delivered about 910 Wh from it and measured a switchover to battery of just over 8 ms. Reviewers disagree about its cooling fans: a UK reviewer reported them running often even at light load, while two US reviews describe different behaviour, one finding the fans inconsistent under a heavy load and the other finding the fan loud at high output but never switching on with a laptop as the load.

Worth checking

  • The independent measurements found come from US 120 V units; none was found on a UK unit.
  • A US review found it shut down above about 2,600 W, against a 3,600 W surge rating.
  • No confirmed firmware fix for the fan reports was found, and a third review reports a different pattern (see the disagreements section).
  • The 230 V figure comes from the regional table in EcoFlow's global user manual rather than the UK product page, the manual's illustrations show the US version, and the Amazon UK listing does not state a voltage. Check the rating label or the Amazon listing before linking to it.
  • EcoFlow UK also sells a standard DELTA 3 and a DELTA 3 Classic. They are different products, and reviews of them are not interchangeable with this one.

    Read original review
    • Third-party measurement

      Across constant loads of 60 W (over USB), 200 W, 500 W and 1,000 W the reviewer recorded roughly 643 to 697 Wh delivered from the 768 Wh battery, the best being about 697 Wh at 500 W and the lowest about 643 Wh at 1,000 W.

    • Third-party measurement

      A full mains recharge in standard mode took about 2 hours 13 minutes and drew 892 Wh; turbo mode took 86 minutes and drew 901 Wh. The best round-trip efficiency across all the tests was 78.1%.

    • Third-party measurement

      In a simulated power cut an office PC and a NAS kept running, which the reviewer took as quick enough switchover, although the time was not measured.

    • Reviewer opinion

      The reviewer judged it a little short on output and storage for general home backup, but a good fit for backing up a home office or a medical device such as a CPAP machine because it runs quietly and switches quickly.

    • Reviewer opinion

      On the reviewer's sample a variable high-pitched noise appeared when the AC ports were switched on and at mains loads below about 100 W, which could be a nuisance for very light backup loads in a quiet room.

    Check before relying on this

    • Efficiency figures assume the battery went from completely empty to full, as the reviewer states.
    • The reviewer's sample made an intermittent high-pitched noise at low AC loads and could not say whether it was specific to that unit.
    • Switchover was judged in a simulated power cut with an office PC and a NAS, and was not timed.
    • The page's spec table also lists a first-reviewed date of 29 February 2024; the byline and structured data give 15 March 2024, which is used here.

    • Third-party measurement

      The reviewer measured about 890 Wh delivered from the 1,024 Wh rating, or 87%, which it called well above average among the units it has tested. It also measured a recharge rate of about 512 Wh per hour, taking around two hours from empty.

    • At a 1,479 W load, close to its 1,500 W rating, the unit ran for 37.5 minutes against an expected 43, which the reviewers put at about 87.5% efficiency. The inverter and fans were working hard at that load.

    • The unit held a load peaking at 1,560 W for about 10 minutes before the reviewers stopped the test, and shut off after a couple of seconds at 2,200 W, below Jackery's stated 3,000 W surge peak. The reviewers called that standard behaviour for power stations in this class.

    • A US-model recharge from empty took about 1 hour 35 minutes in standard mode and just under an hour in the 1,200 W emergency mode. Solar recharging took about 4.5 hours under optimal conditions with up to 400 W of input.

    • Internal temperatures reached up to 138 F (about 59 C) under that load, with fans running inconsistently, which the reviewers called a concern for continuous heavy use.

    EcoFlow DELTA 3 Plus review: Lightning-fast charging with a noisy flaw

    Article · Published 17 January 2025 · Checked 1 November 2026
    Source of the unit not stated

    Read original review

    • After more than a month of use the UK-based reviewer found the fans running frequently even with little connected, although EcoFlow's stated behaviour is that they stay off below 600 W, which made it a poor fit as a quiet always-on backup supply. The reviewer, citing another review's video, said EcoFlow had yet to address it.

    • With a vacuum cleaner drawing over 700 W the reviewer could still hear the unit's fan over the vacuum and was unsure whether the temperature control was working properly. With a laptop as the load the fan never switched on, although the unit still warmed. The reviewer said similar fan and temperature complaints appeared in other reviews.

    Check before relying on this

    • The reviewer is US-based and the unit is presumed to be a US 120 V model; the variant is not stated.
    • Fan behaviour was judged by ear with a vacuum cleaner drawing over 700 W and with a laptop as the load; no noise or temperature figures were given.
    • The reviewer did not test solar charging.

Disagreements and limitations

  • DELTA 3 Plus cooling-fan behaviour

    T3's UK reviewer reported the fans running frequently even at light loads. The Solar Lab's US reviewers reported them running inconsistently under a heavy load, and a US review syndicated from How-To Geek found the fan loud at high output but never switching on with a laptop as the load. The first two concern different loads and the third contradicts the T3 report at light loads, so the behaviour may vary by unit or firmware. The T3 and Solar Lab reviewers expected a software fix, and no source confirmed one, so the behaviour of current units is unknown.

  • DELTA 3 Plus efficiency

    StorageReview calculated about 88.9% from a full discharge at an unstated load, while The Solar Lab calculated about 82% at 1,573 W. Efficiency usually falls as load rises, so the figures are not necessarily contradictory, but neither was measured at the tens-of-watts loads typical of home backup.

  • Elite 100 V2 noise at high output

    OutdoorGearLab found the fan stayed quiet with the unit pushed to 80% of its rated output. Notebookcheck reported that Bluetti's under-30 dB figure applies only in a silent mode limited to 600 W, and found the unit noticeably louder in full-power mode. The two reviews used different methods and the modes tested may differ, so how loud the unit gets at high output is not settled.

UK home backup buying guidance

FoxVerdict editorial view

Watts and watt-hours measure different things

Watt-hours (Wh) describe how much energy a unit stores. Watts (W) describe how much power it can deliver at once. A unit can have plenty of stored energy but still be unable to run a high-power appliance if the appliance draws more watts than the unit's AC output rating.

Usable energy is lower than the headline capacity

Independent measurements found less than the rated capacity: roughly 643 to 697 Wh from the 768 Wh AC70, about 890 Wh from the 1,024 Wh Elite 100 V2 (variant not stated, probably US 120 V), and about 910 Wh from the DELTA 3 Plus on a US unit. A figure of around 925 Wh can be calculated here for the Jackery from one US result at a near-maximum load. Efficiency varies with load and method, so treat runtime calculations as upper estimates.

A rough way to estimate runtime

Divide usable watt-hours by the power your devices draw in watts. As an illustration only, assume a router drawing 10 W, four LED lamps totalling 20 W and a laptop charging at 50 W. With 660 to 925 Wh usable, that gives roughly 66 to 92 hours, 33 to 46 hours and 13 to 18 hours before overhead. The inverter that provides mains output uses power itself: a US review of the Elite 100 V2 calculated about 16 W with nothing connected, and none was found for the other three units. As an illustration, a router drawing 10 W through a unit with a 16 W idle draw would take about 26 W from the battery in total, so the same battery would run it for about 38% as long (10 W divided by 26 W). Idle draw has not been measured for the other three units, and the Elite figure is the reviewers' own calculation, so treat this as an illustration rather than a prediction. Measure your own loads with a plug-in energy monitor, and use USB or DC outputs for very small loads where possible.

Check UK compatibility

Look for a 230 V, 50 Hz AC output and sockets suitable for UK plugs, directly or via an adaptor. Specifications can differ between regional versions of the same model. In this research the DELTA 3 Plus states its UK voltage in the manufacturer's manual rather than on its UK product page, so confirm that the product you buy is the UK or EU version rather than relying on the model name alone.

Fridges and freezers need extra care

A fridge or freezer compressor draws more power when it starts than when it runs, so check the appliance label and the power station's surge rating, and expect runtime to depend on how often the compressor cycles. One reviewer estimates 8 to 16 hours for a fridge-freezer on the AC70 without describing a test. No source found measured a fridge or freezer on any of the four units, so this roundup makes no runtime claim for one.

Why these do not power a whole house

These units run low-power essentials, not a home. A UK reviewer notes that most kettles are beyond even the AC70's power lifting mode, which is limited to appliances rated at 2,000 W or below, and the continuous ratings of all four units are 1,000 to 1,800 W. A 1.8 kW heater setting cut out after about 10 seconds on a Jackery in another UK review. The AC70's power lifting mode can run some simple resistive heating loads at reduced voltage, but a UK reviewer saw the supply fall to 182 V, and it is not suitable for electronics.

Medical equipment and the Priority Services Register

If a power cut would put someone's health at risk, a portable power station should not be the only plan. Check the device's power rating and supply requirements with its manufacturer or clinic, and check the power station's manual for switchover time and any automatic shut-off that could cut small loads; the AC70's eco mode can switch off outputs when little power is drawn, according to Trusted Reviews. Ask your electricity supplier or network operator about the Priority Services Register. UK Power Networks says it is open to people who rely on medical equipment or refrigerated medicines, and covers London, the East and the South East of England, while other areas have their own network operators.

Treat solar charging as a top-up

The Energy Saving Trust says panels still generate on cloudy days and in winter, but less, because days are shorter, cloud is more likely and sunlight is less intense; it gives no winter percentage. The independent solar readings found for these units are limited: 76 W from a bundled 100 W panel in hazy September sun on a Jackery, with little gain on a cloudy day, and a US review's solar recharge of about 4.5 hours under optimal conditions with up to 400 W of input. No source found measured these units' solar charging in a UK winter. Check each unit's maximum solar input and connectors, as adaptors may be needed, and treat solar as a way to extend backup rather than a guaranteed full recharge.

Plug devices in directly

Portable power stations are designed to power devices plugged into them. Connecting one to fixed household wiring, or to a socket using a lead with a plug at each end, can send power back into the supply and is dangerous. It should only be done through an installation designed for that purpose by a qualified electrician.

Methodology and sources

This roundup is a research summary. It combines manufacturer specifications, attributed findings from independent reviews, and FoxVerdict's editorial interpretation. Each statement is labelled by type so you can tell which is which.

Choosing sources. Independent reviews are included where the reviewer describes how the product was used or measured and says where the unit came from, or where the page makes clear what was and was not measured. Each source is linked, dated, and checked again before this page is updated. Where a source has limitations, such as a non-UK variant or a manufacturer-supplied unit, we say so. Measurements from US-model units are labelled as such. Products are included only where a UK variant could be confirmed from the manufacturer's documentation.

Checking specifications. Specifications come from each manufacturer's own product page and were checked on 30 October 2026 against the Amazon UK listing. Where a UK mains voltage was not stated on the product page, it was taken from the manufacturer's manual and the product's limitations say so. Where pages disagree with each other, the limitations say that too. Prices are not shown because they change too often to keep accurate.

No first-hand testing

FoxVerdict has not physically tested any product in this roundup. Specifications come from the manufacturers. Findings are our own summaries of independent reviews, each attributed and linked to its source. The interpretation is FoxVerdict's editorial view and is labelled as such.
