The best cordless grass trimmers, compared.
Top pick: NovorikX XLST3A20-2-UK Best value: Jwdj 21V metal blade kit – Lowest saved price among scores of 84 or higher, £27.86 at a score of 86 from 4.3 and 596 reviews. Updated 22.10.2026.
A cordless grass trimmer, usually called a strimmer in the UK, cuts the grass a mower leaves along edges, fences and obstacles. A suitable one shows the cutter, the width of the path, and whether a battery and charger are in the box. Nylon line is the usual choice against paths and walls. Pivoting plastic blades avoid a spool and can snap on a hard surface. A metal blade or a circular saw in a cheap kit is a different risk, even when the title says grass trimmer. A pack from a system you already own often matters more than a higher voltage printed on the title. Line and plastic-blade heads of this type are often 24–30 cm. Several metal-blade kits are nearer 12–15 cm. Width finishes an edge faster. It does not mow a lawn. If a bullet and the weight cell disagree, keep both figures and do not average them. The order of those checks is in the [cordless grass trimmer buying guide](/hub/lawn-and-garden-equipment/cordless-grass-trimmer/sub/cordless-grass-trimmer-buying-guide).

Personal buying guide
Question 1 of 2
Which cutter do you want?
The NovorikX, model XLST3A20-2-UK, is a 30 cm line trimmer at a saved £79.98, with 1.6 mm nylon and a head the bullets call a trimmer and an edger. The listing prints 4.7 from 19 reviews, so eight points come off and the comparison score is 86, level with larger samples rather than ahead of them. In that thin set of reviews, buyers call it light in the hand with the battery fitted, and one cites edges in a 30 square metre garden. Assembly took about five minutes in one review, and spare line was noted as included. The title says Command Feed while the bullets describe an automatic feed with no bump, so the feed method is not one sentence. The weight bullet is 1.7 kg and the weight cell is 2.65 kg, and the bullets claim two 20 V 2.0 Ah packs and 40 to 60 minutes total while the battery cell says one pack included. One mixed review is cut off in the saved file, so a repeating mechanical fault is not visible, and the warranty bullets say three years on the unit and two on the batteries.
Pros
Cons
Best for: You want a 30 cm line trimmer and can live with a 19-review listing.
Less suitable: You want a review count in the thousands, or a Bosch or Einhell battery you already own.
Specifications
Common questions
How many batteries are included?
The bullets say two 20 V 2.0 Ah packs and 40 to 60 minutes total. The battery cell says one lithium-ion battery is included. A review treats two batteries as a plus.
Why is the score not higher with 4.7 stars?
The listing has 19 reviews. This comparison takes 8 points off a star score when the count is under 100. 4.7 times 20 is 94, then 86.
What does it weigh?
The bullets say 1.7 kg. The weight cell says 2.65 kg. Both are printed. This page does not average them.
The Bosch EasyGrassCut 18V-26 cuts a 26 cm nylon path at 9,000 RPM, and the saved amazon.co.uk price is £63 for the tool only. The listing prints 4.5 from 2,848 reviews, which puts it first in this set when stars are multiplied by 20 and a tie is broken by review count. Reviewers describe a light machine for a short tidy: one says a partner can use it comfortably, and another found the line easier to load than on a previous strimmer. Edging is a click and a twist of the handle, and no wheel is listed. Line diameter is not in the saved file, so you cannot match a spool size from this page alone. One review says it consumes batteries quickly, and another says it is not for heavy-duty jobs. The £63 price does not include a Bosch 18 V pack or charger, and the tool will not run until you add both.
Pros
Cons
Best for: You already own Bosch 18 V batteries and want a light line trimmer for edges.
Less suitable: You have no Bosch 18 V pack, or you need a metal blade for thick brush.
Specifications
Common questions
Does the EasyGrassCut 18V-26 include a battery?
No. The title says battery and charger are excluded. The saved price is £63 for the tool only. You need a Bosch 18 V pack you already own.
How wide is the cut?
The listing cell says 26 cm. The speed cell says 9,000 RPM. Line diameter is not in this saved file.
Can it edge?
The bullets say you change to edging with a click and a twist of the handle. A wheel is not listed.
The WORX WG163E cuts a 30 cm path with 1.65 mm Command Feed line, spool WA0004, at a saved price of £79.99. The listing prints 4.5 from 1,921 reviews, the same star-times-20 score as the Bosch and second on review count. UK reviews cite lawn edges, a sloping front garden, and an allotment where grass had reached 20–25 cm, sometimes needing a second pass. Reviewers treat two batteries as necessary, yet the file disagrees: the style name and the battery cell say two 2.0 Ah packs, while the box line lists one WA3639 battery and charger WA3880. The same bullets print 18 V and 20 V MAX for PowerShare, which is one platform label, and they state a one-hour charge, though one reviewer found the first charge slow. The weight cell is 3.87 kg, the heaviest in this set, and one reviewer still preferred the balance of a long-owned Stihl petrol strimmer. A three-year warranty is stated only if you register online, and a safety guard and edger wheel are in the box line.
Pros
Cons
Best for: You want a 30 cm line trimmer with an edger wheel and a stated charger.
Less suitable: You need the lightest tool in this set, or a Bosch or Einhell battery you already own.
Specifications
Common questions
How many batteries does the WG163E listing include?
The style name and the battery cell say two 2.0 Ah packs. The box line lists one WA3639 battery and charger WA3880. Both statements are in the saved file.
What line does it use?
The box line says a 1.65 mm spool, 3 m, part WA0004. Command Feed advances line with a button. Cutting width is 30 cm.
Is 20 V a different battery from 18 V?
The same bullets print 18 V and 20 V MAX for WORX PowerShare. It is one platform label, not two systems.
The LEEIKOO PSYUT is a blue metal-blade kit at a saved £37.99, with six metal blades, two saw blades, pruning shears, and gloves in the box list. The listing prints 4.5 from 32 reviews, so the comparison score is 82 after the small-sample deduction. The bullets claim two 2.0 Ah packs, up to 30 minutes combined, a shaft of about 85 to 120 cm, and a 90 degree pivoting head at up to 11,000 RPM. One reviewer cleared nettles and bramble runners behind a shed, and another notes the packs arrived charged. The same critical review says a blade kept working loose on a nettle patch, calls that an injury risk, and puts each pack at about 10 minutes against the 30 minute combined claim. The warranty cell prints 2, and one reviewer could not send the warranty email printed on the leaflet. Weight is about 1.5 kg in the bullets and 2.62 kg in the cell, cutting width is not stated, and the battery cell says two 9 V batteries against the 21 V title.
Pros
Cons
Best for: You want two stated 2.0 Ah packs and metal blades, and you will check that the blade stays tight.
Less suitable: You want a large review count, a stated cutting width, or nylon line.
Specifications
Common questions
How long does the listing say it runs?
The bullets say up to 30 minutes combined, depending on blade and conditions. The cell also says 30 minutes. One review says about 10 minutes from each pack on a full charge.
Do the blades stay on?
One review says a blade kept working loose on a nettle patch and calls that an injury risk. The teeth also wore out in that review. Stop if a metal blade loosens.
Is the warranty contact in the box reliable?
The cell prints 2. One reviewer could not send the warranty email printed on the leaflet. That is one report.
This Einhell GC-CT 18/24 Li, model 3411172, is a body-only plastic-blade trimmer at a saved £48.43, with a 24 cm cut at 8,500 RPM. The listing prints 4.4 from 13,827 reviews, the largest count in this comparison. The bullets put 20 plastic knives in a compartment on the auxiliary handle, and the head is listed as rotatable by plus or minus 90 degrees with a flower guard. Owners who already had Power X-Change packs describe the price as low once that battery exists, and more than one review says it cuts brambles and thick nettle stems. A telescopic shaft suited a reviewer who is 6 ft 1 in. The weight cell says 1.8 kg while the size cell also prints 2.71 kg, and a review notes that fitting your own battery adds more. One reviewer calls the battery bay poorly made, and another says the blade is for lighter work than a mains strimmer, so the £48.43 figure is the tool only.
Pros
Cons
Best for: You already own Einhell Power X-Change batteries and want plastic blades rather than line.
Less suitable: You have no Einhell battery, or you want nylon line against paving.
Specifications
Common questions
Does this Einhell include a battery?
No. The bullets say it is supplied without a battery and charger. The saved price is £48.43 for the tool. It needs an Einhell Power X-Change pack.
What cuts the grass?
Plastic knives, not nylon line. The bullets say 20 knives live in a compartment on the auxiliary handle. Cutting width is 24 cm at 8,500 RPM.
Which weight figure is on the listing?
The weight cell says 1.8 kg. The size cell also prints 2.71 kilogram. A review says your own battery adds weight on top.
The Einhell kit, model 3411125, is the 24 cm plastic-blade trimmer with one 2.0 Ah Power X-Change battery and a system charger at a saved £51.54. The listing prints 4.3 from 4,185 reviews, and the style cell says Old Model. There is no minute claim in the bullets; one allotment review says at least 25 to 30 minutes, which is that garden. Reviewers like the lack of a cable and the fact that plastic blades do not need a spool, and the weight cell is 2.09 kg. One reviewer who first thought it looked like a toy then used it on a large rewilded garden and was pleased. The limit is the guard: one review could not fit the protector shield and used the trimmer without it, which that reviewer calls not ideal, and the spare-blade count is not in this file.
Pros
Cons
Best for: You own no Einhell batteries yet and want a plastic-blade kit rather than a spool.
Less suitable: You want nylon line, or you need the shield to be simple to fit.
Specifications
Common questions
Is a battery included?
Yes. The bullets say one 2.0 Ah Power X-Change battery and a system charger. The saved price is £51.54.
How long do reviewers say the battery lasts?
One allotment review says at least 25 to 30 minutes. That is one garden, not the listing's own runtime cell. This file has no minute claim in the bullets.
Does the guard fit?
A flower guard is in the bullets. One review could not attach the protector shield and used the trimmer without it, which that reviewer calls not ideal.
This Jwdj kit is the lowest saved price in the set at £27.86, with 4.3 from 596 reviews, which is why it is the best-value row among scores of 84 or higher. The box list names two lithium batteries, a charger, 10 plastic blades, four S-shaped metal blades, five ropes, one circular saw blade, goggles, and a glove, on a 120 mm head. The speed cell says 18,000 RPM no-load while the bullets also say 6,000 RPM working speed, so those two figures stay side by side. One allotment review says it handled growth a known-brand strimmer did not, while another says it has very little power and a battery flat in about 15 minutes. Two reviews put a pack at about 15 to 20 minutes, and one says the battery feels hot. A plastic blade that catches the ground digs in, which one reviewer contrasts with nylon line, and another wanted a wider guard. The battery cell still says one 9 V battery, which conflicts with the two-pack bullet, so you should not treat the kit list as a single settled fact.
Pros
Cons
Best for: You want the lowest saved price and accept a small metal-blade head.
Less suitable: You want a 26-30 cm nylon line, a named 18 V platform, or a guard you will not wish was wider.
Specifications
Common questions
What is the cutting width?
The listing cell says 120 mm. That is a small head next to the 24-30 cm line trimmers in this set.
How long do the batteries last in reviews?
Two UK reviews say about 15 to 20 minutes. One says the battery feels hot. The bullets do not print a minute claim in the captured text. The title says 21 V. The battery cell says one 9V battery.
Are goggles in the box?
The bullets list 1 goggles and 1 glove, plus a dual switch. One review still calls the instructions rubbish and the power low.
The Highlandhue GCJ001 is a green wheeled trimmer at a saved £28.49, with 4.2 from 147 reviews and a cutting-width cell of 5.9 inches. The title lists two 2,000 mAh batteries, a roller, and a telescopic shaft, and one buyer chose the wheels for a father nearly 80. Reviewers use it along a fence and around flower beds, and they keep the metal blade for when the plastic blades wear. Plastic blades are called fragile in more than one review, and one review says the round blade is poor on long grass because grass goes under the guard. That same theme includes a head that started to smoke when grass packed underneath, so clearing a clog is part of using it, not a reason to bin the guard. The speed cell says 20,000 RPM while the bullets say 6,000 RPM idle and 2,000 RPM working, and the battery cell says two 12 V batteries against a 21 V title. A bullet claims at least 60 minutes from one battery and a free replacement for a tool that does not work, which is a seller promise rather than a measured session in the reviews we saved.
Pros
Cons
Best for: You want wheels on a low saved price and will keep the guard on.
Less suitable: You want nylon line, or you are about to take the guard off because grass catches.
Specifications
Common questions
Does it have wheels?
The title says a roller. One review bought it for that reason and says it works with and without the wheels.
What runtime does the listing claim?
The bullets say one battery can run for at least 60 minutes, and the cell says 60 minutes. Charge time is stated as 2 to 3 hours. Reviews in the captured text talk about fragile plastic blades more than about minutes.
What do reviews say about the guard?
One review says grass catches with the guard on and the blade then cuts poorly. Another says long grass packed under the guard and the head started to smoke until it was cleared.
The Umbryxion GX-141 is a blue blade kit at a saved £39.98, printing 4.2 from 90 reviews, so the score falls to 76 after the small-sample deduction. The weight cell is 1.13 kg, the lightest cell in this set, and the bullets itemise 15 pieces: three circular saws, four metal blades, five cross heads, and five plastic blades. The title says string trimmer, but the bullets do not describe a nylon spool, and the width cell is 5.0 with no unit. Two 4,000 mAh packs and about two hours are claimed, and one review is still on the first pack after four uses. Against that, one review says the charger does not work and a replacement could not be found, so the tool could not be used. One review says the safety wire and back-feed protection fell off into the undergrowth, and a review of a tool bought in August 2026 says the head smoked on the second use and then died. The battery cell says two 12 V batteries, which conflicts with the 21 V title, and a one-year manufacturer warranty is stated on the listing.
Pros
Cons
Best for: You want the lightest stated weight and two large claimed packs, and you will test the charger immediately.
Less suitable: You want a nylon spool, a width in centimetres, or a review count over 100.
Specifications
Common questions
Is this a string trimmer?
The title says string trimmer. The bullets list 15 blades and saws, not a nylon spool. The cutting-width cell is 5.0 with no unit.
What runtime is printed?
The cell and the bullets say about 2 hours. One review is still on the first of two packs after four uses. Another says the charger does not work, so the tool could not be used at all.
What failed in reviews?
One review says the safety wire and back-feed protection fell off. One review, bought in August 2026, says the head smoked on the second use and the tool then died. One review says the charger does not work.
The yellow-green Jwdj AMX is a mixed-blade trimmer at a saved £32.62, printing 4.1 from 629 reviews. The saved bestseller line ranks it first in Grass Trimmers, which is Amazon’s ranking, not the score on this page. The bullets list 10 plastic blades, four long metal blades, two circular saws, and two ropes, with a 6 inch width cell and 10,000 RPM. Reviewers call it very light for a small garden or an allotment, and one says it has more power in use than the flimsy first look suggests if you are gentle. The bullets claim 40 to 60 minutes, while the battery cell says two 9 V batteries against a 21 V bullet. One UK review says the supplied charger did not charge, so the first job is to confirm the pack actually takes a charge. The weight bullet says 3.2 pounds and the weight cell says 2.76 kg, and a bullet that calls it a mower does not match how reviewers describe a strimmer.
Pros
Cons
Best for: You want a cheap mixed-blade head and will check the charger on day one.
Less suitable: You want a 24-30 cm line trimmer from Bosch, WORX, or Einhell.
Specifications
Common questions
How wide is the cut?
The cutting-width cell says 6 inches. The bullets also call the tool a mower. The bestseller cell is Grass Trimmers.
Does the charger work?
The bullets do not name a charger. One UK review says the supplied charger did not charge. That is one review, not a rate.
What runtime is claimed?
The bullets say 40 to 60 minutes from a 21 V battery. The battery cell says two 9V batteries. Reviews in the captured text call the battery life decent rather than timing it.
The red Wrneaoch is a 15 cm metal-blade trimmer at a saved £29.98, with 4.1 from 251 reviews. The title says 27 blades and a retractable handle, and the bullets claim removable wheels, an adjustable head angle, and 40 to 60 minutes. One review assembled it in under five minutes, and another says one battery cut tall grass and brambles. Runtime in the reviews we saved is shorter than the bullet: one says about 20 minutes, then a battery change. One buyer chose it because it felt light enough for an elderly gardener, and another says it is fine for ordinary tasks but not as robust as expected. The limit that should stop a purchase is the charger: one UK review says it exploded when plugged in, and that reviewer will not recommend the tool. The battery cell says one 9 V battery, which conflicts with the 21 V bullet, and the bullets claim a 650 W motor with no decibel figure.
Pros
Cons
Best for: You want a 15 cm wheeled metal-blade head and will inspect the charger before the first charge.
Less suitable: You will not risk a marketplace charger, or you want nylon line.
Specifications
Common questions
What width does the listing print?
15 cm. The speed cell says 18,000 RPM. The bullets claim a 650 W brushless motor and 40 to 60 minutes. No decibel figure is printed.
What happened to the charger in reviews?
One UK review says the charger exploded when it was plugged in and tells people not to buy it for that reason. Stop using a charger that sparks. That is one review, not a failure rate.
How long did one battery last?
One review says about 20 minutes, then a change. Another says one battery cut tall grass and brambles. Both are single gardens.
This black mixed-blade listing, model FTY, is a saved £29.68 with 4.0 from 521 reviews, the lowest star figure in the set. The title starts with Erzneaoch and the brand cell says Jwdj, so the name on the carton is not one settled fact. The blade list matches the yellow-green Jwdj row: 10 plastic blades, four metal blades, two circular saws, and two ropes, at 8,300 RPM. Width is 6 inches in one cell and 14 cm in the size cell, which is why both figures stay on the card. One review says the plastic blade was enough and the metal blade stayed unused, while another says the metal blade comes loose during use but does not come off. A further review calls a unit faulty and unsafe and asks for a refund without describing the fault, so you cannot tell what failed. Instructions are called poorly worded, the battery cell says two 9 V batteries against a 21 V bullet, and one review does confirm two rechargeable packs.
Pros
Cons
Best for: You already know this blade kit and only want the black colour of the same bullet set.
Less suitable: You want a stable brand name, a tight metal blade, or a nylon-line head.
Specifications
Common questions
Which brand name is on the listing?
The title starts with Erzneaoch. The brand cell says Jwdj. The model cell says FTY and the part cell says OSK02. This page does not pick one and delete the other.
Does the metal blade stay tight?
One review says the metal blade comes loose during use but does not come off, and tells you to be cautious. Another review has not needed the metal blade because the plastic one was enough.
What is the star rating?
The saved listing prints 4.0 from 521 reviews, the lowest star figure in this set. One review calls a unit faulty and unsafe without describing the fault.
Twelve amazon.co.uk listings were scored on 22 October 2026. The published score is the star rating times 20. If the saved review count is under 100, 8 points come off. A tie uses the higher review count, then the lower saved price. There was no lab test. The top pick is the highest score. Best value is the lowest saved price among scores of 84 or higher. Cutter, battery and width are how you choose. They are not extra weights inside the number.
Amazon stars
100%The published score is the amazon.co.uk star rating times 20. A 4.5 is 90 and a 4.4 is 88. If the saved review count is under 100, 8 points come off, so a 4.7 from 19 reviews is 86 rather than 94. A tie uses the higher review count, then the lower saved price. The 8-point cut is part of this score. It is not a second percentage. The 90 on the Bosch row is a worked example of 4.5 times 20, not a weight.
Start with the cutter, then the battery, then the width. A cordless grass trimmer finishes edges. It does not replace a mower. Nylon line is for paving and walls. Plastic blades suit light grass if you keep spares. Metal blades stay in the open, with the guard on and the blade tight. A body-only price needs a pack from the same family before you compare it with a kit. Read a conflict in the listing as a conflict. The table is the model set. This section is the order of the decision.
A cordless grass trimmer is a battery tool for the strip a mower misses. In the UK it is usually called a strimmer. You use it along a fence, around a tree and against a path. It is not a lawn mower, and a wider head does not turn it into one. The first check is the cutter. Nylon line is the usual choice against paving and walls. Pivoting plastic blades avoid a spool and suit light grass if you keep spares. They can snap on a hard surface.
A body-only shelf price is the tool. It will not run until you add a battery and charger of the same family. Put that cost next to a kit before you call one of them cheaper.
An 18 V family pack and a marketplace 21 V kit do not interchange. A line that prints 18 V and 20 V MAX is one platform. A 9 V or 12 V cell beside a 21 V title is a conflict, not a single voltage.
A 40–60 minute bullet and a review that says 15–20 minutes are both on the listing. Name which one you are using. Do not remove the guard because grass catches in it, and stop if the head smokes, a blade loosens, or the charger sparks.
The cutter decides where the tool can work. Nylon line is the usual choice against paths and walls. Pivoting plastic blades avoid a spool. They suit light grass if you keep spares, and they can snap on a hard surface. A metal blade or a circular saw is for open growth only, and only if the blade stays tight and the guard stays on. A title that says grass trimmer, or string trimmer, does not make a saw blade a nylon head. If the bullets list blades and no spool, keep that disagreement.
A body-only price is the tool. It will not run until you add a battery and a charger of the same family. A kit price includes whatever the box list actually contains, and you still read the battery cell. If the box list says two packs and the cell says one, both stay. If the title says 21 V and the cell says a 9 V battery or a 12 V battery, do not merge those lines into one voltage. A higher number on the title is not a better system.
Three typical situations, each with a recommendation from this comparison.
You want nylon line against a path and you already have Bosch 18 V packs. The Bosch EasyGrassCut 18V-26 is the body only, 26 cm, at a saved £63, with 4.5 from 2,848 reviews. The price does not include a battery or a charger. Skip it if you have no Bosch pack.
You already own Einhell Power X-Change packs and you want plastic blades rather than a spool. The GC-CT 18/24 Li body, model 3411172, is 24 cm at a saved £48.43, with 4.4 from 13,827 reviews. Battery and charger are not in the box. The weight cell says 1.8 kg and the size cell also prints 2.71 kg.
You want the lowest saved price and you accept a 120 mm mixed-blade head. The Jwdj kit is £27.86, with 4.3 from 596 reviews and a score of 86, which is why it is best value among scores of 84 or higher. The battery cell says one 9 V battery against a 21 V title. That badge is the price rule, not a verdict that a metal blade cuts better.
The top pick is the Bosch EasyGrassCut 18V-26 at a saved £63, with 4.5 from 2,848 reviews and a score of 90. WORX is also 90, from 1,921 reviews, so the higher review count takes the badge. Battery and charger are not in the Bosch box. Best value is the Jwdj kit at £27.86, score 86 from 4.3 and 596 reviews, the lowest saved price among scores of 84 or higher. That badge is the price rule. It is not a verdict that a metal blade is the better cutter.
Jwdj 21V metal blade kit
Lowest saved price among scores of 84 or higher, £27.86 at a score of 86 from 4.3 and 596 reviews.
