You use one for phones, a router, lights, and sometimes a fridge in a power cut, or for quiet camping. Separate a useful unit from a toy by continuous watts, watt-hours, waveform, and a real UK 13 A socket. How to size watts and watt-hours is in the [backup generator buying guide](/hub/electrical-equipment/backup-generator/sub/backup-generator-buying-guide). On these amazon.co.uk listings, a backup generator is almost always a portable power station: a battery and an inverter, not a petrol engine. It runs while you can fuel it, and says never to run it indoors because of carbon monoxide. None of the twelve rows here is a petrol genset. If that is the machine you need, compare an [inverter generator](/hub/electrical-equipment/inverter-generator).

The FOSSiBOT F2400 lists 2,400 W and 2,048 Wh of LiFePO4 in the title, with a claimed 4,800 W surge and three AC outlets, at £649.00. The amazon.co.uk line is 4.6 from 346 reviews, the highest stars in this set, though the saved sample mixes UK titles with other countries. UK titles call it well made, while a Spanish note says anything other than light bulbs emptied the battery in seven hours and a German note complains about after-sales help. The title says 240 V, the attribute says 230 V, and a bullet says 110 V. A panel is sold separately, and the word UPS appears with no switchover time printed. It is the highest single-pack claim here, and you should read the plate for voltage before you rely on it.
Pros
- 2,400 W and 2,048 Wh LiFePO4 in the title, 4,800 W surge claimed
- 4.6 from 346 reviews, the highest star line in this set
- Three AC outlets and a five-year warranty on the listing
- UK titles in the sample call it well made
Cons
- Title 240 V, attribute 230 V, bullet 110 V
- Review sample is mixed-country, not a UK-only file
- Panel sold separately
- UPS is named and the switchover time is not stated
Best for: You want the largest single-pack watt and watt-hour claim in this set and you will confirm the outlet voltage on the hardware.
Less suitable: You need a panel in the box, a UK-only review file, or a listing whose voltage lines agree.

The VTOMAN Jump 600X lists 600 W of claimed pure sine, a 1,200 W surge, and 268.8 Wh of LiFePO4, with two AC outlets and a 230 V attribute, at £239.99. The amazon.co.uk line is 4.4 from 473 reviews, and the first 50 texts are United Kingdom. Reviewers describe camper hair dryers, phones kept charged, a small camping kettle, and LED lights in a power cut. The same notes say heavier appliances shut it down, and that USB-C was hit and miss in one camping review. Some texts assume an expansion battery or a panel this listing does not include. AC input is printed as 170 W and also as up to 270 W. It is the step up when an 80–150 W box is too small and a 2 kWh station is more than the job.
Pros
- 600 W pure sine claimed, 1,200 W surge, 268.8 Wh LiFePO4
- Two AC outlets and a 230 V attribute
- 4.4 from 473 amazon.co.uk reviews
- UK notes cover campers, a small camping kettle, and LED backup
Cons
- Heavier appliances shut it down, in the review notes
- USB-C called hit and miss in one camping review
- No expansion battery and no panel in this box
- AC input is printed as both 170 W and up to 270 W
Best for: You want a mid station around £240 with a stated pure sine claim for lights, chargers, and small camper loads under 600 W.
Less suitable: You need a household kettle, a heater, or a panel and an expansion battery in the carton.

Our view
The VTOMAN FlashSpeed 1500 bundle is a 1,500 W station with a claimed 3,000 W surge, an extra battery, and a 200 W panel, at £899.99, shipping as three packages. Capacity is printed as 1,548 Wh, as 2,956 Wh with the extra battery, and also as 3,096 Wh. The amazon.co.uk line is 4.4 from 31 reviews, with 19 UK texts in the file. Those notes praise months of use and solar charging on cloudy UK days, including places where a petrol generator was refused. They also describe a faulty extra battery, charging that stopped past about 90% after about two weeks, and a delivery that looked returned. Waveform is not stated, and an official report on a FlashSpeed 1000 is a different model.
Pros
- Extra battery and 200 W panel included with the 1,500 W station
- UK notes mention solar charging on cloudy days
- Used where a petrol generator was refused, in the review file
- Three 230 V outlets stated
Cons
- 4.4 from 31 reviews, a thin sample
- Capacity printed as 1,548 Wh, 2,956 Wh, and 3,096 Wh
- Faulty extra battery and a charge ceiling around 90% in the notes
- Waveform not stated; £899.99 is the dearest row here
Best for: You want the extra battery and a 200 W panel in one VTOMAN bundle and you can live with 31 reviews and conflicting capacity lines.
Less suitable: You want a stated pure sine claim, one agreed watt-hour figure, or a lower price without the bundle.

Common questions
What arrives in the bundle?
The listing says the station, an extra battery and a 200 W Pro panel, sent as three packages.
Which watt-hour figure should you read?
The capacity bullet says 1,548 Wh, or 2,956 Wh with the extra battery. Another field says 3,096 Wh, and the highlight says 1,408 Wh extra.
Does the listing say pure sine?
Those words are not in the bullets. It does claim 1,500 W rated and 3,000 W peak.
Our view
This VTOMAN Jump 2200 ASIN is the station without a solar panel: 2,200 W of claimed pure sine, a 4,400 W surge, 1,408 Wh of LiFePO4, and three 230 V outlets, at £499.99 and about 20 kg. The 4.3 from 140 line is the same UK review text as the panel kit, so a panel-in-the-box comment is not evidence for this carton. Those texts describe camper kettles, fridges, and a cool box kept for several days once the owner added a panel. The fan is called very noisy under load, and extra-battery switchover fails in some notes. Fault lines include front ports dead within three weeks while the display showed about 73%. A separate 200 W panel is quoted at about six to nine hours, so this pack is a high-output battery, not a fuel refill.
Pros
- 2,200 W pure sine claimed, 4,400 W surge, 1,408 Wh LiFePO4
- Three 230 V outlets stated
- UK review text covers camper kettles, fridges, and weekend off-grid use
- Wall charge claim of about 45 minutes
Cons
- No panel in this box; the 140-review line is shared with the kit
- About 20 kg, and the fan is called very noisy under load
- Extra battery is sold separately and fails to switch in some notes
- Fault notes include dead ports within three weeks and a later no-charge failure
Best for: You want the 2,200 W station for camper or backup loads and you will buy a panel separately if you need solar.
Less suitable: You want the 110 W panel in the same carton, or a review file that is only about this station-only pack.

Common questions
Is the 110 W panel in this box?
No. This pack list has no solar panel. The panel is on ASIN B0D4Q45KD3.
Can the capacity grow?
The listing says 1,408 Wh, expandable to 2,956 Wh with a Jump 1500 extra battery sold separately.
Are the 140 reviews only for the station-only pack?
The same 4.3 from 140 line and the same review text are on the panel-kit ASIN.
Our view
This £569.99 ASIN is the same 2,200 W and 1,408 Wh Jump 2200 claim plus a 110 W panel in the box. The 4.3 from 140 reviews is shared with the station-only ASIN, and several texts describe an extra battery or a larger panel than this kit. Reviewers run camper loads and keep a cool box going for several days with a panel connected. They also criticise a noisy fan, solar charging slower than the advert, and the 20 kg weight. One replacement story says the seller lost the solar panel. The outlet attribute says two, against three AC outlets in the bullet, and the extra battery is still sold separately.
Pros
- 110 W panel packed with the 2,200 W / 1,408 Wh station claim
- Three AC outlets in the bullet, pure sine claimed
- Review notes include multi-day cool-box use with a panel connected
- £569.99 against £499.99 for the station without a panel
Cons
- Shared 4.3 from 140 reviews with the station-only ASIN
- Some reviews describe a larger panel or an extra battery this kit does not include
- Outlet attribute says 2 against 3 AC outlets in the bullet
- Fan noise, slow solar versus the advert, and a lost panel in one replacement story
Best for: You want this Jump 2200 and the 110 W panel in one carton for camper solar, and you accept the shared review file.
Less suitable: You do not need a panel, or you need the extra battery included rather than sold separately.

Common questions
What is in the box that the £499.99 pack lacks?
This package list adds one 110 W solar panel.
Is the extra battery included?
No. Expansion to 2,956 Wh needs a Jump 1500 extra battery, sold separately.
Does the listing claim pure sine?
Yes. It says a pure sine wave 2,200 W load, with a 4,400 W surge.
Our view
The MARBERO M82 is an 80 W continuous, 120 W peak station with 88.8 Wh and one 220 V outlet, at £93.99. The listing shows 4.0 from 7,329 reviews, and the same rating line and UK review text sit on the M82 Plus and the M168 Plus. In that shared sample, reviewers praise the 1.04 kg body, charge several phones with power left, and one person ran an 84 W guitar amp for just over eight hours. The same texts say a laptop lasted about an hour, a self-inflating bed would not inflate, and a 30 W practice amp would not run. A unit that stopped holding charge after about six months is in the fault notes. The solar panel is not in the box, so this is a small AC box for loads that stay under 80 W.
Pros
- 80 W continuous and 120 W peak stated, with 88.8 Wh
- 1.04 kg and a bright torch in the shared reviews
- Shared UK notes include several phones and one long amp session
- 12-month warranty on the listing, AC adapter in the box
Cons
- The 4.0 from 7,329 line is shared with two other MARBERO ASINs
- 220 V attribute, waveform not stated
- A 30 W amp and a self-inflating bed failed in the shared reviews
- Panel is not in the box
Best for: You want a light box for phones and a load under 80 W, and you will not treat 7,329 as reviews of this model alone.
Less suitable: You need a stated 230 V, 50 Hz pure sine outlet, or a panel in the carton.

Common questions
Is the 4.0 score from 7,329 reviews of this M82?
The saved listing prints 4.0 from 7,329, and the same review text is on the M82 Plus and the M168 Plus.
Does it include a solar panel?
No. The listing says it can take a 15–24 V panel, and the panel is not in the box.
What AC voltage does the attribute give?
220 V AC, 50 Hz, 80 W running and 120 W maximum.
Our view
The MARBERO M168 Plus lists 100 W continuous and 150 W peak from 97.68 Wh, at £103.54, and both the AC bullet and the attribute say 220 V / 60 Hz. UK mains are 230 V at 50 Hz, so that pair is a problem on the page itself. The 4.0 from 7,329 line is the same shared text as the other two MARBERO ASINs, not a separate census of this model. Those reviews include phone charging and one 84 W amp run of just over eight hours, plus slow charging and a unit that stopped charging after about six months. The listing says it does not support loads over 100 W. At 1.32 kg it is still a carry box, and you should leave it if you need the page to state 50 Hz.
Pros
- 100 W continuous and 150 W peak from 97.68 Wh
- 1.32 kg, still a carry weight
- AC adapter and cigarette-lighter adapter in the box
- Shared reviews include phone charging and one long amp run
Cons
- AC line prints 220 V / 60 Hz
- The 7,329-review line is shared, not a census of this model
- Loads over 100 W are excluded on the listing
- Panel sold separately, and no solar cables in the shared review notes
Best for: You want about 100 W in a small MARBERO body and you have checked that 220 V / 60 Hz is acceptable on your loads.
Less suitable: You need a listing that states 230 V and 50 Hz, or an independent review file for this model.

Common questions

The low-power bullet says it does not support appliances rated over 100 W, and names portable fridges and motor loads as incompatible.
Why does the frequency say 60 Hz?
Both the attribute and the AC-outlet bullet say 220 V / 60 Hz.
Is this a separate 7,329-review sample?
No. The same 4.0 from 7,329 line and the same UK review text are on the other two MARBERO ASINs.
Our view
The MARBERO M82 Plus repeats an 80 W continuous and 120 W peak claim with one 220 V outlet, at £104.99, while the bullets print both 98 Wh and 111 Wh. The warranty bullet says 12 months and the warranty field says two years. The 4.0 from 7,329 figure is the shared MARBERO line, not a separate UK census of the Plus. Shared notes praise the 1.04 kg body and phone charging, then report a laptop lasting about an hour and a 30 W amp that would not run. A charge failure after about six months is in the fault list, and the panel is not included. You pay more than the M82 without one agreed watt-hour figure on the page.
Pros
- 80 W continuous and 120 W peak, one AC outlet
- 1.04 kg and a three-level torch in the listing
- AC adapter and cigarette-lighter cable in the box
- Shared UK notes cover phones, tablets, and one portable fridge mention
Cons
- 98 Wh and 111 Wh are both printed
- Warranty bullet says 12 months; the field says two years
- Shared 7,329-review line, not a separate test of the Plus
- 220 V attribute, waveform not stated, panel not included
Best for: You specifically want the M82 Plus body for phones and a sub-80 W load, after you pick one of the two watt-hour figures as unknown.
Less suitable: You want one agreed capacity, a stated 50 Hz UK socket, or a lower price than the M82 for the same 80 W class.

Our view
The VCLPOWER listing is a USB and bulb pack at £69.99, with 75 Wh of LiFePO4 and a 10 W panel in the title. The wattage attribute instead says 75 kilowatt hours, and the bullets do not describe an AC socket. The amazon.co.uk line is 3.9 from 200 reviews. UK titles call it a workable phone charger outdoors, then complain that solar charging missed expectations, that the panel lacked kickstands, and that a USB port was not connected. One review says the panel would not charge the pack, and one unit is described as stopping within weeks of a 1 June delivery. The package bullet counts one panel and the included-components field counts two, so treat 75 Wh in the title as the capacity claim.
Pros
- Title claims 75 Wh LiFePO4 and a 10 W panel in the package bullet
- 3.9 from 200 amazon.co.uk reviews
- USB charging and bulb ports for phones and small lights
- £69.99 for a pack that includes a panel claim
Cons
- No AC socket is described in the bullets
- The attribute says 75 kilowatt hours against 75 Wh in the title
- Solar charging and a missing kickstand come up in UK titles
- Panel count disagrees between the package bullet and the included-components field
Best for: You want USB and a couple of bulbs for camping, and you will ignore the kilowatt-hour attribute.
Less suitable: You need a 230 V socket, or you are buying it mainly for the 10 W panel to refill the pack.

The SinKeu R150 is a 99 Wh station with one 230 V / 50 Hz outlet rated 150 W maximum, at £109.99. The amazon.co.uk line is 3.8 from 1,334 reviews, and the first 50 texts in the file are United Kingdom. Reviewers use it for phones, a router, camping fans, and a 3-pin socket on a shed, and one two-year note says it still works. The same file says AC runtime was about an hour and a half, that the fan was noisy, and that the socket would not run the loads people expected. Fault notes include charging that stopped in under a year, a burning plastic smell on first use, and a unit dead on a first camping night. The panel is not included, so read that defect trail before you rely on it in a cut.
Pros
- 150 W AC at a stated 230 V / 50 Hz
- 99 Wh, with an AC charger in the box
- 3.8 from 1,334 reviews, UK texts in the sample
- Phones, a router, and camping fans come up in the praise notes
Cons
- AC runtime about an hour and a half in one criticism, then a long recharge
- Panel not included; one added panel pulled under 14 W
- Fault notes include no charge, a burning smell, and a dead unit on a first night
- Chemistry is not named on the listing
Best for: You want a small station whose listing actually prints 230 V and 50 Hz for phones, a router, or a light fan.
Less suitable: You need pure sine stated on the page, a panel in the box, or a pack with a clean fault record.

Does the listing name the battery chemistry?
No. Chemistry is not in the bullets or the attribute block.
Our view
The Oumefar listing is a hand crank rated about 20 W at a claimed 2,000 rpm, so you only get power while you turn it. On amazon.co.uk it is £42.79 with a 3.4 line from five reviews, and the saved file holds one Spanish review rather than five UK texts. That note calls it a workable emergency charger and asks for a better support so cranking is less awkward. No stored watt-hours and no AC socket are stated, and the attribute block still prints 4 stroke beside a hand-crank description. Weight is 758 g in one bullet and 820 g in the attribute. It is a last-resort USB crank, and it stops the moment you stop turning.
Pros
- About 20 W of USB output while you crank
- No fuel and no stored pack to maintain
- £42.79, the lowest shelf price in this set
- One review treats it as an emergency charger
Cons
- No watt-hours and no AC socket stated
- The file has one Spanish review, not five UK texts
- 4 stroke on the attribute does not match the crank bullets
- The only review asks for a better support while cranking
Best for: You need a hand-turned USB trickle when every battery is already flat and you can keep cranking.
Less suitable: You want stored power for an evening, a 230 V socket, or a UK review sample.

The listing gives about 20 W while it is generating. It does not state a battery capacity in watt-hours.
Is there a UK mains socket?
No AC socket is described. The special-features line names a USB port.
How many UK reviews are in the saved listing?
The listing score is 3.4 from 5 reviews. The file contains one review, from Spain.
Our view
The VTOMAN Jump 100 is an 89.6 Wh LiFePO4 box at £49.99, with a title claim of 100 W AC and 65 W USB-C PD and a 230 V attribute. Across 130 amazon.co.uk reviews the line is 2.9, the weakest star average in this set. UK reviewers describe an air bed and phones through an 11-hour cut, and several praise the 65 W port. The same sample says a full charge added about 10% to one phone, that small AC loads lasted about five minutes, and that one reviewer calls the AC output modified sine. The listing itself does not state the waveform, and fault notes include a unit that would not take a charge after one use. At 1.2 kg it is easy to carry, and it is a weak bet for a laptop or a television.
Pros
- 89.6 Wh LiFePO4 at £49.99
- Title claims 100 W AC and 65 W USB-C PD
- 1.2 kg, light enough for camping in the reviews
- Some UK reviews used it through an 11-hour cut for an air bed and phones
Cons
- 2.9 from 130 amazon.co.uk reviews
- Waveform is not on the listing; one UK reviewer calls it modified sine
- Short AC runtimes and weak phone top-ups in the same sample
- Fault notes include a pack that would not charge after one use
Best for: You want the cheapest LiFePO4 box here with an AC title for phones and a short air-bed inflate, and you have read the 2.9 line.
Less suitable: You need a stated pure sine output for a laptop, a TV, or speakers.

How we compared
Twelve backup generators on amazon.co.uk were scored from saved listings dated 20 October 2026. There was no lab test. The published score is the amazon.co.uk star average times 20, so 4.6 is 92 and 2.9 is 58. Review volume is not inside the score. Shared rating lines, thin samples, and voltage clashes stay in the assessment. The scores were not reduced again, and price is not inside the score.
1
Amazon star line
70%The published score is the amazon.co.uk star average times 20. A 4.6 line is 92 and a 2.9 line is 58. Review volume is not inside that number, so a line of 7,329 and a line of 31 can share a star band.

Backup generator buying guide
Start with continuous watts, then watt-hours, then whether the listing says pure sine and a UK-suitable socket. Price comes after those three. The notes below follow that order for these twelve amazon.co.uk listings, saved on 20 October 2026. None of the scores is a lab test.
What is a backup generator on these shelves?
On these amazon.co.uk listings, a backup generator is almost always a portable power station: a battery and an inverter, not a petrol engine. You use one for phones, a router, lights, and sometimes a fridge in a power cut, or for quiet camping. A petrol generator is a different machine. It runs while you can fuel it, and National Grid says never to run it indoors because of carbon monoxide. None of the twelve rows here is a petrol genset.
Best for
- A flat where you need lights, phones, and broadband for an evening and cannot run petrol outdoors
- Quiet camping with USB and a small AC socket, once the listing states the watts and the voltage
- A household comparing a 1–2 kWh station with a petrol inverter for a longer cut, without connecting either to the consumer unit
Not ideal for
- Feeding the house by plugging a station or a petrol set into a wall socket
- A kettle, a heater, or a fridge bought as an 80–150 W box
- Medical equipment, a hard-wired boiler, or any connection to the consumer unit without a competent electrician
Mistakes to avoid
- 1
Reading generator and expecting a fuel engine
On these twelve listings the machine is a battery and an inverter, or a hand crank. A petrol set runs while you can fuel it and must stay outdoors. A 4 stroke line on a battery attribute is noise.
- 2
Mixing up watts and watt-hours
Watts are what the inverter can supply at once. Watt-hours are how long that load can run. An 80–150 W station cannot run a kettle. A 2,400 W station still stops when the watt-hours are gone. The VCLPOWER attribute says 75 kilowatt hours; the title says 75 Wh.
- 3
Trusting a shared star line or a photo of a panel
Three MARBERO ASINs share one 4.0 from 7,329 line. The two Jump 2200 ASINs share one 4.3 from 140 line. A panel in the title photo is not proof it is in the box. The station-only Jump 2200 has no panel; the £569.99 kit does.
What to weigh up
Continuous watts and watt-hours
HighContinuous watts decide whether the appliance can start. Watt-hours decide how long it can stay on. In this set the hand crank is about 20 W with no stored watt-hours. VCLPOWER does not describe an AC socket. The small AC boxes are about 80–150 W and under about 120 Wh. The Jump 600X is 600 W and 268.8 Wh. The Jump 2200 is 2,200 W and 1,408 Wh. The FOSSiBOT F2400 title says 2,400 W and 2,048 Wh. The FlashSpeed bundle is 1,500 W, with an extra battery taking a claimed capacity toward 2,956 Wh.
Waveform, voltage and the UK socket
HighPrefer a listing that says pure sine and 230 V, 50 Hz. The Jump 600X and both Jump 2200 rows claim pure sine, and they print a 230 V attribute. The FOSSiBOT title says 240 V, the attribute says 230 V, and a bullet says 110 V. The FlashSpeed bundle states 230 V and does not state a waveform. The Jump 100 does not state sine, and a UK reviewer called the AC output modified sine. The M168 Plus attribute block says 220 V and 60 Hz.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Quiet camping with a small socket
You want quiet USB and a small AC socket whose listing prints 230 V and 50 Hz. The SinKeu R150 is about £109.99, 150 W and 99 Wh. A panel is not in the box.
A 1–2 kWh station, not petrol
You are weighing a large battery against a fuel generator for a longer cut. The FOSSiBOT F2400 is about £649.00, with 2,400 W and 2,048 Wh claimed. Confirm the outlet voltage on the hardware.
Common questions about backup generators
Which backup generator is the top pick in this set?
The top pick is the FOSSiBOT F2400, about £649.00, with 4.6 from 346 amazon.co.uk reviews. The title claims 2,400 W and 2,048 Wh of LiFePO4, and the score is 4.6 times 20, which is 92. That is the highest star line in this set. It is not a lab test. The title says 240 V, the attribute says 230 V, and a bullet says 110 V, so read the plate before you rely on it. A panel is sold separately. The word UPS has no switchover time printed.
Which listing is the best value?
The best value is the VTOMAN Jump 600X at about £239.99. It claims 600 W pure sine, a 1,200 W surge and 268.8 Wh of LiFePO4, with two AC outlets and a 230 V attribute. The line is 4.4 from 473 reviews, and the score is 88. Among rows here with at least 500 W continuous AC claimed and an independent UK review count above 100, it is the lowest price. The 80–150 W boxes are a different job. The Jump 2200 costs more, on a shared review file.
How much do these backup generators cost on amazon.co.uk?
On these twelve shelves, saved on 20 October 2026, prices run from about £42.79 for the Oumefar hand crank to about £899.99 for the FlashSpeed 1500 bundle. The small AC boxes sit around £49.99 to £109.99. The Jump 600X is about £239.99. The Jump 2200 station is about £499.99, and the same station with a 110 W panel is about £569.99. The FOSSiBOT F2400 is about £649.00. These figures are this set only. Other brands overlap the bands, and the shelf price will move.
Can you plug a backup generator into a wall socket to feed the house?
No. Do not plug a power station or a petrol generator into a wall socket to feed the house. A government consultation says BS 1363 does not permit plugs and sockets to connect generating equipment. SI 2026/848 later allows a narrow plug-in solar microgenerator that does not store imported energy. A backup battery and a petrol set sit outside that exception. Selected house circuits need a changeover fitted by a competent electrician. A battery station has no exhaust in normal use and can sit indoors if the maker allows it.
When is a petrol generator the other machine to look at?
A battery station stops when the watt-hours run out. A petrol generator runs while you can fuel it, and it must stay outdoors. National Grid says never run a fuel generator indoors, in a garage, or by an open window, because carbon monoxide has no smell. None of the twelve listings here is a petrol genset. A 4 stroke line on a battery attribute is noise. If you are choosing a fuel inverter for a longer cut, that is a different shelf from these battery stations.
Are the MARBERO 7,329 reviews three separate tests?
No. The M82, the M82 Plus, and the M168 Plus each print 4.0 from 7,329, and the saved files share that rating line and overlapping review text. Treat it as one shared sample, not three censuses. The two Jump 2200 ASINs likewise share one 4.3 from 140 line. A star count that is identical across ASINs is not three tests, or two tests. Review volume is not inside the score. The score is the star average times 20.
Will one of these run a fridge for a set number of hours?
This page does not claim a runtime for a named fridge. An 80–150 W station cannot run a kettle or most heaters, and the M168 Plus listing says it does not support loads over 100 W. A 2,200–2,400 W inverter can start more appliances, but only for as long as the watt-hours last. A UK maker guide uses runtime about equal to watt-hours times 0.8, divided by the load in watts. That is a rule of thumb, not a test of these models. Read the appliance plate first.
When should you call a professional, and how do you report a cut?
Call a competent electrician for any connection to the consumer unit, a hard-wired boiler, or a changeover switch. Stop after a shock or a burning smell, and do not rely on a station for medical equipment until that setup has been agreed. Report a power cut on 105. If someone depends on electricity for medical kit, join the free Priority Services Register. A short automatic switchover is a UPS job. Milliseconds are not printed on the listings here that use the word UPS.
Our verdict
In this set of twelve amazon.co.uk listings, the top pick is the FOSSiBOT F2400. It is about £649.00, with 4.6 from 346 reviews, and the title claims 2,400 W and 2,048 Wh of LiFePO4. The score is 4.6 times 20, which is 92, the highest star line here. The title, the attribute, and a bullet do not agree on voltage, and that limit stays in the assessment. The best value is the VTOMAN Jump 600X at about £239.99, with 4.4 from 473 reviews, 600 W pure sine claimed and 268.8 Wh. Among listings with a stated continuous AC output of at least 500 W and an independent UK review count above 100, it is the lowest price. The score is 88. None of these scores is a lab test.
