The best Einhell cordless grass trimmers, compared.
Top pick: Einhell GE-CT 18/25-1 Li-Solo Best value: Einhell GC-CT 18/24 Li kit – 4.3 from 4,185 reviews, listed at £51.54 with a 2.0 Ah pack and a fast charger, the lowest kit price. Updated 22.10.2026.
A cordless grass trimmer cuts the lawn edge and the tufts a mower leaves against fences, walls and borders. You buy one when a lead will not reach the bed, or when a matching battery is already in the shed. The checks that still hold if the models change are cutting width, the cutter, voltage, and what is in the box. A short plastic-blade head suits soft grass kept off slabs. Nylon line is the cutter beside walls, flags and stones. Woody clearance with a metal blade belongs on a brush cutter. An 18 V pack runs an 18 V body. A listing that needs two packs will not run on one. A body sold alone is the tool only. Count a turning head only where the listing states an angle. A plant guard is not eye protection, and the guard stays on while you cut. These tools fall under the outdoor noise rules for a guaranteed sound-power mark. The order of those checks is in the [cordless grass trimmer buying guide](/hub/lawn-and-garden-equipment/einhell-cordless-grass-trimmer/sub/einhell-cordless-grass-trimmer-buying-guide).

Personal buying guide
Question 1 of 2
What do you already own?
The GE-CT 18/25-1 Li-Solo is the only listing in this set that puts 20 plastic blades and a line spool in one box, at £59.99, with a 25 cm title width, a 180-degree head, three tilt positions and a metal flower guard. The star line is 4.6 from 90 reviews, the highest stars here and the reason the file score is 92, but that sample stays under the 100-review line used for the top pick, and the research file held one UK review. Battery and charger are not included. Amazon prints 7,000 rpm. Item weight is 3.11 kg, the same figure as the 36 V listing, and that cell may be a mismatch, so do not plan the lift around it. The GE-CT 18/25-1 manual for this family says to fit the guard, click each blade on, and cut grass that is dry; that sheet is not a script for the GC-CT models. Warranty and assembled dimensions were not in the fields read. Choose it when you want both cutters on one 18 V body and can live with a thin review base; skip it if you wanted the most reviewed tool or a battery in the box.
Pros
Cons
Best for: You already own an 18 V pack and want one body that can take blades on open grass and line near hard edges.
Less suitable: You want a large review sample, a kit that includes a charger, or a confirmed weight.
Specifications
Common questions
Does the GE-CT 18/25-1 include a battery?
No. The bullets say the battery and charger are not included.
Can it use blades and line?
Yes. The bullets and the included list name 20 plastic blades and one trimmer line spool.
How many UK reviews are in the file?
One. It is positive. The 4.6 score is from 90 ratings on the listing. Reviews from other countries were not used.
The GC-CT 18/24 Li Solo is a 24 cm plastic-blade body at £39.95, listed at 1.35 kg, with a telescopic aluminium shaft and 20 trimmer knives. It carries this comparison’s top pick because it shares the highest star line among listings with more than 100 reviews, at 4.5 from 5,015 amazon.co.uk reviews, ahead of the 28 cm line model on review count. The score in the file is 90. You still buy the pack and charger separately; the style cell says Strimmer Only. The bullets do not state a rotation angle or a tilt count, so do not assume the head turns for vertical edges the way the GE-CT 18 Li Solo listing does. Blade snap on stone is a recurring limit for this cutter type, not a sign the motor has failed. Dimensions on the page print 18 x 1 cm, which is not an assembled length, so you cannot plan storage from that cell. It suits a small lawn and an existing 18 V pack if you keep the knives off paving.
Pros
Cons
Best for: You want the strongest star line with a large review count in this set, you already have one 18 V pack, and the grass is clear of stone.
Less suitable: You need a head the listing says will turn for edges, a battery in the box, or line for walls.
Specifications
Common questions
Is a battery included with this 24 cm solo?
No. The title says without battery, and the bullets say the battery and charger are purchased separately.
Does the shaft adjust?
Yes. The bullets describe an individually adjustable telescopic long handle in light aluminium.
What is the listed speed and weight?
The listing prints 8,500 rpm and an item weight of 1.35 kg. The dimensions cell of 18 x 1 cm is not a usable shaft length.
The GE-CT 18/28 Li Solo is an 18 V nylon-line body at £64.95, with a 28 cm width, a 180-degree head, a three-way tilt and fully automatic thread tracking in the bullets. It scores 4.5 from 1,904 amazon.co.uk reviews, level on stars with the top pick but with fewer reviews, and the file score is 90. The title says without battery, and the included cell names the trimmer only. Listed weight is 2.5 kg. The shaft is not described as telescopic. Amazon prints 9,000 rpm, while Einhell UK prints a lower idle speed and 1.6 mm line for article 3411242, so those two sources stay separate. The page asks about wet grass and the bullets do not answer it; the dry-grass line in the GE-CT 18/25-1 manual is that other model’s instruction, not this one. Line is the cutter Einhell points at walls and stones, though a stuck feed is a known complaint on line heads in this set, and eye protection still applies.
Pros
Cons
Best for: You already own one 18 V pack and your edges run along walls, slabs or paths.
Less suitable: You want the cheapest blade body for open lawn, or a pack in the box.
Specifications
Common questions
Does the 28 cm model include a battery?
No. The bullets say this is the body only and that the battery and charger are sold separately.
How does the line feed?
The bullets say fully automatic thread tracking. Line diameter and spool length are not on the Amazon cells.
Can it trim wet grass?
The listing asks that question and does not answer it in the bullets. Treat wet grass as unanswered.
The GE-CT 18 Li Solo is the most reviewed listing here, at 4.4 from 13,827 amazon.co.uk reviews, and it sits at rank 9 in Grass Trimmers on the page read for this file. At £48.43 you get a 24 cm plastic-blade body with a telescopic shaft, a motor head the bullets state as plus or minus 90 degrees, and five tilt positions. The score is 88. Supply is without battery and charger, and the assembly cell says Yes, so the first job is fitting the tool before any pack you already own will run it. Item weight prints 1.8 kg while the size cell also prints 2.71 kg, so quote both or neither. The battery cell says lithium polymer batteries are required, which does not match the Power X-Change wording in the bullets; treat that cell as a listing oddity, not as proof the platform uses a different chemistry. Einhell UK’s figure of about 40 minutes on a 2.0 Ah pack is attached to this GE-CT 18 Li-Solo family in our notes, not to every ASIN in the table. It is the blade body to choose when you want a stated edging angle and a huge review sample, and the wrong one if your edges are paving.
Pros
Cons
Best for: You already own one 18 V pack and want the blade body whose listing actually states a turning head.
Less suitable: You want a ready-to-run kit, nylon line beside flags, or a single weight you can trust from one cell.
Specifications
Common questions
Does this GE-CT 18 Li include a battery?
No. The bullets say it is supplied without a battery and charger. The battery cell says lithium polymer batteries are required, while the bullets name Power X-Change packs.
Can the head be turned for edges?
The bullets say the motor head rotates plus or minus 90 degrees and tilts to five positions, with a telescopic shaft and an adjustable auxiliary handle.
Which weight does the listing print?
Item weight is 1.8 kg. The size cell also prints 2.71 kg. Both figures are on the page.
The GE-CT 18/30 Li is a 30 cm line body at £64.98, three pence above the 28 cm solo, with a 90-degree head, three tilt positions, an adjustable aluminium bar and a wheel kit in the included list. Across 1,135 amazon.co.uk reviews the line is 4.4, and the score is 88. One 18 V battery and a charger are sold separately. The bullets describe automatic jogging and a thread spool, which is the practical difference from a knife head when you are following a flagstone edge. Amazon prints 9,000 rpm; Einhell UK’s idle speed for article 3411250 is lower, and the manufacturer page also names 1.6 mm line, so do not merge those figures into the Amazon cell. The dimensions cell prints 18 x 30 cm, which is not a shaft length, and no warranty sentence was in the fields read. Wheels help you hold a height, but they do not make the tool safe with the guard off, and line can still throw debris.
Pros
Cons
Best for: You want wheels and a stated 90-degree head for a longer edge, and you already have an 18 V pack.
Less suitable: You need a battery in the box, or a short open lawn where a cheaper blade body is enough.
Specifications
Common questions
Does the GE-CT 18/30 Li include a battery?
No. The bullets say the body only, and the battery and charger are sold separately.
What helps with edging?
The bullets say a 90-degree head, three tilt positions and guide wheels. A wheel kit is in the included list.
Is the shaft length a settled fact?
The bullets say the aluminium bar adjusts with a lever. One UK review from a person who is 5 ft 9 in said it was still too short to stand upright.
The GE-CT 18 Li 2.5 Ah listing is the dearest blade kit here at £79.95, and the box names a 2.5 Ah battery, a charger and 20 plastic blades. It is 4.4 from 487 amazon.co.uk reviews, a smaller sample than the older kits, and the score is 88. The bullets say the motor head is 90 degrees rotatable left and right, with a five-way tilt and a telescopic shaft, on a tool styled as the new model at 2.25 kg. Amazon’s speed cell says 3,800 rpm, while Einhell UK prints an idle speed of 8,500 for article 3411219, so this page does not pick one figure as corrected. No warranty sentence was in the fields read. You pay for a larger printed pack and a stated edging head compared with the £51.54 2.0 Ah kit, which does not state a rotation angle. Plastic blades still meet the limit described in a 2022 UK write-up of one Einhell blade trimmer, where knives snapped on concrete, so the extra amp-hours do not change the cutter. It fits a first purchase when you want 2.5 Ah and a turning head on open grass, not a line tool for slabs.
Pros
Cons
Best for: You want a new-model blade kit with a named 2.5 Ah pack and a head the listing says will turn.
Less suitable: You already own a pack, you need line, or you want the lowest kit price.
Specifications
Common questions
What is in the box?
The included line lists the trimmer, 20 plastic blades, a charging device and one 2.5 Ah battery.
What speed does Amazon print?
The speed cell says 3,800 rpm. Einhell UK prints an idle speed of 8,500 for the same article number, so the two figures stay separate.
How many UK reviews were in the file?
Five. They praise a light cut and battery swap. One says the head has a single blade. A repeated defect is not described in that file.
The GE-CT 18 Li kit is £68.99 and does include a battery and a fast charger, which puts it in the ready-to-run group, but the listing does not print the amp-hours. It is 4.3 from 5,333 amazon.co.uk reviews, a larger sample than the cheaper 2.0 Ah kit, and the score is 86. The highlight says a rotating motor head without an angle, assembly is required, and the style is the old model at 2.15 kg. A retailer page for article 3411197 has claimed up to 55 minutes on a 2.0 Ah pack; that is a shop sentence, not a measurement on this Amazon listing, and you cannot check it against a printed capacity here. You pay £17.45 more than the £51.54 kit that does name 2.0 Ah, for a rotating-head mention and more reviews, without knowing the pack size. Blades are still the cutter, so paving remains the wrong surface. Buy it only if you specifically want this older GE-CT kit and accept an unprinted capacity; otherwise the named 2.0 Ah or 2.5 Ah kit is the clearer box.
Pros
Cons
Best for: You want a GE-CT blade kit with a battery in the box and can accept that the pack size is not on the page.
Less suitable: You want a named 2.0 Ah or 2.5 Ah pack, or line rather than plastic blades.
Specifications
Common questions
Is a battery included?
Yes. The cell says one lithium-ion battery is included, and the included line names a battery and a fast charger. Amp-hours are not printed.
How is this kit different from the £51.54 kit?
This is model 3411197 at £68.99. The £51.54 listing is model 3411125 and names a 2.0 Ah pack. This included line does not name the amp-hours.
Does the head rotate?
The highlight says a rotating motor head. It does not print the angle.
The GC-CT 18/24 Li kit is this comparison’s best value because it is the lowest printed price that includes a battery and a charger: £51.54 with a 2.0 Ah Power X-Change pack, a fast charger and 20 plastic blades. Across 4,185 amazon.co.uk reviews the line is 4.3, and the score is 86. The listing calls it a telescopic handle with a flower guard, styled as the old model, at 2.09 kg. A rotating head is not printed, so this kit does not match the GE-CT bodies if vertical edging is the job. The assembly cell says No, yet a UK review still said the protector shield was hard to fit, which is worth allowing time for before you judge the motor. Einhell’s roughly 40-minute note is for the GE-CT 18 Li-Solo on a 2.0 Ah pack, not a measured session for this article number 3411125. It is the first-time buy when you own no pack and the lawn is soft grass; it is a weak saving if you already have a 2.0 Ah pack and only needed the £39.95 solo.
Pros
Cons
Best for: You are buying your first Power X-Change trimmer and want a printed 2.0 Ah pack in the same box.
Less suitable: You already own a pack, or you need a stated 90-degree head or nylon line.
Specifications
Common questions
What battery is in this kit?
A 2.0 Ah Power X-Change battery and a fast charger. The battery cell says one lithium-ion battery is included.
Is this the same listing as the other 24 cm kit?
No. This is model 3411125, styled as the old model, at £51.54. The other old-model kit is model 3411197.
Does the listing say assembly is required?
The assembly cell says No. One UK review still said the protector shield was too hard to fit.
The GC-CT 18/24 Li P-Solo is the cheapest body in this set at £32.56, and it is a 24 cm plastic-blade trimmer listed at 1.2 kg with 20 blades and a flower guard in the box. Across 3,328 amazon.co.uk reviews the line is 4.2, a large sample for a solo tool that still does not include a battery or a charger. The style cell says Trimmer Only, so the shelf price is the tool, not a working kit. A rotating or tilting head is not stated, and the shaft is not described as telescopic, which is the gap against the dearer GE-CT bodies. Plastic blades in this category are for open grass; a 2022 UK write-up of an Einhell blade trimmer found knives that snapped on concrete, and that limit applies to how you use this head too. The flower guard is a plant shield, not eye protection, and the listing does not print a noise or vibration figure. If you already own one 18 V Power X-Change pack and your edges stay off the flags, this is the light entry body; if you need line against paving, it is the wrong cutter.
Pros
Cons
Best for: You already own an 18 V Power X-Change pack and want a light 24 cm blade body for soft edges away from slabs.
Less suitable: You need a battery in the box, a stated edging angle, or nylon line against walls and flags.
Specifications
Common questions
Does the GC-CT 18/24 Li P-Solo include a battery?
No. The style is Trimmer Only, and the bullets say it comes without a battery and charger. The size cell says the same.
What does it cut with?
Plastic blades. The included list names 20 plastic blades and a flower guard. A line spool is not listed.
Does the listing say the head turns for edging?
No. The bullets that were read do not state a rotatable or tiltable motor head.
The GE-CT 36/30 Li E-Solo is a 30 cm line trimmer at £94.95 that needs two 18 V Power X-Change packs and does not include them or a charger. It is 4.2 from 2,501 amazon.co.uk reviews, and the score is 84, level with the cheapest solo on score despite the higher shelf price. The bullets state a single 2 mm line, up to 9,000 rpm, a split shaft, a shoulder strap and a wall holder, at 3.11 kg. Einhell’s own UK shop showed £113.95 for article 3411300 when it was checked; the comparison uses the Amazon price. One pack will not run it, because the twin-pack arrangement on this tool means two batteries at once. Reviews in this set describe the bump feed often needing the head opened, and one UK report of more than an hour was on two 4.0 Ah packs, which is an anecdote rather than a specification. Do not call it brushless; that word is not in the listing. It is the body for a longer edge when you already own two packs and want 2 mm line, and a costly mistake if you thought £94.95 was a complete kit.
Pros
Cons
Best for: You already own two Power X-Change packs and want a 30 cm, 2 mm line body with a split shaft.
Less suitable: You own one pack, you wanted a cheap blade trimmer, or the growth needs a metal blade and a harness.
Specifications
Common questions
How many batteries does the 36 V listing need?
The battery cell says two lithium-ion batteries are required. The style is Strimmer Only, and the item type says it is supplied without a battery and charger.
What line does the listing state?
The bullets say a single 2 mm line and a cutting width up to 30 cm, with a line spool. The highlight says auto line-feed.
Does the shaft come apart?
Yes. The bullets say a split shaft for transport, plus a wall holder and a shoulder strap.
Ten amazon.co.uk listings are scored in this folder. Products Compared did not lab-test cutting power, runtime, noise or vibration. The method note publishes no separate percentage split. Every stored score is the amazon.co.uk star rating times 20, so that single rule is the whole number and is recorded at 100 below. A 4.6 from 90 reviews becomes 92 is a worked example for one listing, not a criterion weight. Review count, whether a battery and charger are in the box, the cutting system and a stated head angle decide the badges and the written notes. They are not weights, and they were not rescaled. Where Amazon and the manufacturer print different speeds, both figures stay separate.
Amazon.co.uk star rating
100%The stored score is the amazon.co.uk star rating times 20. A 4.2 becomes 84. A 4.5 becomes 90. It is not a lab test and not an editorial rank. The method note prints no other percentage. The figure 92 is a worked example for one product with 90 reviews at 4.6, not a criterion weight. A review count above 100 decides the top pick when two listings share 4.5. The lowest price that includes a battery and a charger decides best value. Those rules sit outside the number.
Decide the job, whether you already own a pack, and whether the box is a body or a kit before you read the stars. Ten amazon.co.uk listings are on this page. The stored score is the star rating times 20. It is not a laboratory test of cutting power, runtime, noise or vibration.
A cordless grass trimmer cuts edges and the tufts a mower misses. In this category the tools are 18 V bodies, 18 V kits, or a 36 V body that needs two packs. You are not buying a mower, a shrub shear or a brush cutter. Those sit outside this set because they are different tools. The job comes first. Soft edges suit a 24 cm plastic-blade head, kept off paving. Paths, walls and stones suit nylon line. Woody clearance with a metal blade and a harness is a brush cutter, outside this category.
Seven listings are bodies only. The shelf price is the tool. A battery and a charger are a separate purchase. The kits that include both start at £51.54 for a named 2.0 Ah pack. Do not compare that kit with a cheaper body and call the body the complete buy.
The GE-CT 36/30 Li E Solo needs two 18 V packs at once and includes neither of them, nor a charger. £94.95 is the Amazon body price. One pack will not run it. Einhell’s own UK shop was higher when it was checked. This page uses the Amazon price.
Plastic blades are for soft grass. Knives that snap on concrete are a cutter limit. Nylon line is the cutter beside walls and stones. The flower guard protects plants. It is not eye protection, and the tool is not used with the guard off. The lithium-polymer cell on one listing is not the chemistry of the whole Power X-Change range.
The job decides the cutter before any star line does. Soft edges suit a 24 cm plastic-blade head, kept off paving and concrete. Paths, walls and stones suit nylon line. Einhell’s own guide points line at walls and stones, and a metal blade at a scythe or brush cutter, which is outside this category. One listing carries both 20 plastic blades and a line spool. The others are one cutter or the other.
One 18 V Power X-Change pack runs the 18 V tools. The 36 V listing needs two of those packs at the same time and does not include them or a charger. One pack will not start it. A solo price is the tool only. Seven listings are bodies. Three include a battery and a charger: a named 2.0 Ah pack, a kit whose amp-hours are not printed, and a named 2.5 Ah pack. Compare kits on the printed capacity. An unprinted capacity is not the same box as a named one.
Three typical situations, each with a recommendation from this comparison.
You already own one 18 V Power X-Change pack and the grass stays off paving. The GC-CT 18/24 Li Solo is a 24 cm plastic-blade body with a telescopic shaft, listed at £39.95, at 4.5 from 5,015 amazon.co.uk reviews. The battery and charger are not in the box. A rotating head is not stated, so keep it for open grass rather than a vertical edge the listing never describes.
You do not own a pack yet, so a solo price is not a working kit. The GC-CT 18/24 Li kit is listed at £51.54 with a 2.0 Ah Power X-Change pack, a fast charger and 20 plastic blades, at 4.3 from 4,185 reviews. That is the lowest printed price in this set that includes a battery and a charger. A rotation angle is not stated, and the blades are still wrong for paving.
You already own one 18 V pack and the edge runs along slabs or a wall. The GE-CT 18/28 Li Solo is a 28 cm nylon-line body at £64.95, with a 180-degree head and automatic thread tracking, at 4.5 from 1,904 reviews. The battery is not included. If you already own two packs and want 2 mm line, the 36 V body is a separate buy and will not run on one pack.
The top pick is the Einhell GC-CT 18/24 Li Solo: 4.5 from 5,015 amazon.co.uk reviews, score 90, a 24 cm plastic-blade body with a telescopic shaft, listed at £39.95. That is the highest star line among listings with more than 100 reviews. The 28 cm line model also prints 4.5, from 1,904 reviews, so the larger sample takes it. The battery is not in the box. Best value is the Einhell GC-CT 18/24 Li kit: 4.3 from 4,185 reviews, score 86, listed at £51.54 with a 2.0 Ah pack and a fast charger. That is the lowest printed price among listings that include a battery and a charger. A 4.6 from 90 reviews scores 92 and stays under the 100-review line, so it does not take the top pick. Cheaper solo bodies are the tool only.

4.3 from 4,185 reviews, listed at £51.54 with a 2.0 Ah pack and a fast charger, the lowest kit price.
