It’s time to lose that power cord or noisy petrol engine and consider a low maintenance cordless strimmer. We compare features, build quality and run time to see how they stack up against each other.
Commonly known as line strimmers, there are three types of garden strimmer, the most budget-friendly type are corded strimmers, these are usually cheaper but you’re tied down by the power cord getting under your feet and they are not suitable for larger gardens or gardens where there is no plug socket. Then there are petrol strimmers that are powerful and great for long grass and mobility as you don’t need a power source and can be easily refuelled, however, these can be both heavy, noisy and require more maintenance, so are not suitable for everyone and are usually used by professional gardeners.
Finally, one of the most versatile and best types are cordless strimmers powered batteries, thanks to new battery technology, cordless strimmers are now some of the best strimmers available. These newer models are powered by Lithium-ion batteries, we have covered these before when reviewing cordless hedge trimmers and lawnmowers, in general, they have longer running time, much shorter charging times.

Heavy duty and professional use
In addition to the main handle, there’s a secondary handle that reinforces the ability to manoeuvre this strimmer. The line trimmer’s 33cm cutting swathe is larger than average, so you’ll be able to cover areas a lot faster. A pricier strimmer than others though.
Best For Professionals
With long working days unavoidable during the summer for professional gardeners (yes I used to be a professional gardener so I know what it’s like in summer), you need a dependable model like the EGO Power + STX3800 Grass Trimmer if you want to go cordless and leaves the petrol tools behind. This grass trimmer is designed to offer long working times thanks to the powerful battery pack. It has a wide cutting width of 38cm which will serve you when working on small or large areas. This is an amazing bit of kit but the only down side is the price, its extremely expensive but if its with your budget, its worth considering.

Best Cordless Strimmer Reviews
1. Black + Decker 36V 2.0AH Cordless Strimmer
Winner of MY ‘Best Pick’ award for outstanding quality, performance and useful features after 12 months of testing
Watch my video review and see this strimmer in action
- Powerful 36v cordless strimmer ideal for domestic strimming of small and larger gardens.
- Quickly switch to edging mode to finish off the edge of your lawn quickly (my favourite feature)
- The telescopic shaft makes it easier to store as well as being able to adjust the length smaller for the wife to use too more comfortably.
- The main loop handle can also be adjusted up and down the shaft easily.
- Two power setting, Eco mode gives me around 40 minutes of strimming while Turbo mode gives me the extra power for tough weeds and last around 20-25 minutes.
- Charges in only 90 minutes and has a battery indicator charge built into the battery.
- Fold-down plant guard, ideal for strimming around trees and plants to avoid accidentally strimming them.
- 2 years warranty for extra peace of mind
As mentioned, I have been lucky enough to try a few strimmers running this website, some manufactures offer to send them for free but I actually purchased this model myself to test for around £150 from Amazon over 12 months ago.
First impressions were great, all I needed to do was attach the plastic strimmer head guard and the loop handle, took around 5 minutes if that. I extended the shaft by releasing the quick-clip and it was ready to use. The battery was even charged ready to start testing.
So the first thing I noticed was it was fairly lightweight when compared to some of the other models I have used, I’d say its around 3-4kg. I think officially its around 3.5kg but i have no scales handy to check this. The thing is, lighter tools usually means lower quality but with this the Black + Decker model, is extremely well build, all the plastic parts are good quality, durable, it’s fairly substantial and i think the shaft is made from aluminium but I’m not 100% sure, could just be steel but there no signs of rust.
So in terms of power it’s obviously 36v but on checking the specs it runs up to 8500 RPM, in the real world this means it’s got plenty of power and that it does, as much as the DeWalt model I’ve also been using I would think, that’s how it feels anyway.
It actually has two settings ECO, which is more than enough power for finishing the lawn off after mowing, don’t forget the edging feature too which allows you to rotate the strimmer head by pressing a button. This is my favourite feature as I no longer need to finish the edges of the lawn with a pair of scissors or the manual lawn edging shears I have.
In ECO mode I usually get around 35-40 minutes which is good, in TURBO mode which I only really use occasionally for strimming back long grass or nettles that seem to come from know where, it last around 20-25 minutes, not too bad when you consider the power it’s using at full pelt.
One last feature which is also useful but I don’t use that much is the plant protection guard (think that’s what it’s called), this is handy if you strimming around trees, furniture, plants, anything you don’t want the strimmer line to touch.
I think that’s it really, the battery which is a 36v 2.0Ah takes around 90 minutes to charge. Not too long, the DeWalt charges slightly fast at around 70 minutes and that’s a 5Ah battery but only 18v. However, when you think some models can take up to 3 hours to charge, 90 mins is just fine for me.
I have always found that Black + Decker tools are just average, and all though they have always been ok and did the job, I have never really been that impressed by Black + Decker. Just recently I tested some portable work benches, the Bosch model was way better than the Black + Decker alternative, be it more expensive.
However, with this 36v Cordless Strimmer, they have really put a lot of thought into it. For Black + Decker, I can honestly say they have actually made a garden tool I would recommend and is by far better than most alternatives within the same price range.
First impressions were that it is very well made (one box ticked for quality).
Now some models are still underpowered but Black + Decker have fitted this model with a 36v 2Ah battery. What this actually means is that it has plenty of power, but it also has an impressive running time. The running time is around 40 minutes in ECO mode, which is great for most jobs, such as strimming around trees and edging around the lawn. In TURBO mode it lasts around 20-30 minutes, which does a great job at cutting through tough nettles, long grass and thick brush.
The adjustable head, which tilts 180 degrees was great for cutting around the edges of the lawn and the telescopic handle was very useful, as it makes it more comfortable to use, especially for the wife. Finally, it’s not the lightest model but at 3.5kg I think it’s light enough for most gardeners to use comfortably.
Overall, I think it’s a fantastic strimmer with plenty of power and for most people, you can’t really go wrong with this model. The only exception is if you have lots of rough ground to strim or need to use it daily if you’re a professional gardener for example. Then I would go for the DeWalt model or even the EGO model if you have the budget. For everyone else, just get yourself the Black + Decker 36v Cordless Strimmer, you won’t be disappointed.

When fully charged, this grass trimmer offers up to 540 minutes as a brush cutter and 330 minutes as a line trimmer. This is a significant time for you to get some work done. There is a slightly smaller battery pack, the BAC1330 which is cheaper and gives around 240 minutes which may be better suited for domestic use which the exceptional longer run time may not be needed.
To cut through tough overgrowth material with ease, the cordless trimmer has a reversible steel blade with a 38cm cutting width. The wide width helps in covering large areas at a go, therefore, making the work get done faster. The line cutter function which is better for general grass strimming is equipped with a 2.4 mm diameter dual trimmer line to give clean cuts.

It is important to note that the charger and battery pack are sold separately which makes the complete setup fairly expensive. Therefore, it is important to add up all these costs before making the purchase. This gives you an idea of the overall sum you are working with to avoid any surprises. Don’t forget the cost saving though compared to petrol. Other than that, this durable grass trimmer is a dream to work with and it provides good value for money for all things considered for the professional gardener or ground maintenance person looking for the best reliable cordless strimmer.

The DEWALT DCM561P1S 18V Li-Ion XR Cordless Brushless Line Trimmer is one of the best on the market. Combining a sizable battery, a powerful strimmer motor and an array of features to make strimming a breeze, there is a lot to like with this DCM561P1S.
A 33cm cutting swatch makes it ideal for both small and large grass areas, and so is the 18V 5Ah battery and 2-speed variable setting ranging from 0 – 6,000rpm. Keep in mind the lower settings like 4500rpm results to longer runtime of about 40 minutes, while the highest speed offers a lot more powerful cutting but at the expense of shorter runtime of around 25 minutes.
This is further enhanced by the brushless motor outfitted in this cordless strimmer which provides more torque, sustained cutting speeds under various conditions, reduced friction and longer tool life. This makes it suitable for applications that need to use extended runtimes at higher power settings. In addition, the 18V battery charges fully in a matter of 75 minutes, making this tool easier to use in larger gardens that need multiple runs.
What’s more? The DCM561P1S features a fast-loading 2mm dual line bump feed string that can be adjusted accordingly to suit different needs. There’s a professional style guard for extra protection and a secondary handle to enhance manoeuvrability. The main handle is well-padded and features integrated over mould for user comfort during application.
This strimmer from DEWALT guarantees a professional performance because it’s outfitted with a brushless motor. Add the 18V 5.0Ah battery and you have a reliable tool that can complete the job in one go. In any case, it charges up quickly to get back to unfinished work, unlike some other batteries that take hours. Its 33cm cutting diameter will also ensure that you cover acres of space within the shortest time possible.
The fact that you can control speeds from 0 – 6000rpm is something to appreciate as you’ll be able to tackle both wet and dry grass.

There’s even a second handle to improve handling and comfort.
On the downside, this strimmer weighs 7.24kg which is quite heavy compared to other models on this list. Nonetheless, a great choice for anyone seeking a grass strimmer that delivers according to specifications.

The WORX WG163E 18V (20V MAX) Cordless Grass Trimmer is a versatile tool that can double up as a mini-mower or even as a wheeled edger. Converting from one function to another is super-easy and you don’t need any tools. Its two wheels make it easy to cut in a straight line whilst enhancing stability and control.
This strimmer is designed to use an 18V 2.0Ah Lithium-Ion battery and is even compatible with a 20V battery especially if more power is needed for tougher conditions. In fact, it comes complete with 20V 2.0Ah Li-Ion battery packs to ensure that you’ll never run out of power. These batteries not only provide extreme performance but also allow you to interchange with WORX 20V power and garden tools. The charge time is 3hrs.
Better still, the strimmer comes with a telescopic handle that allows you to adjust accordingly to suit your height and convenience. It’s incredibly light at just 3.5kg, so you should be able to use it for extended periods without feeling the effects. In addition, the articulating cutting head makes edging very easy because it can adjust between 0 – 90° angles. This attribute also allows this strimmer to reach into those difficult spaces in your garden.
The cutting width is a decent 30cm so it can tackle longer and thicker growth as well as cover a large area quickly. Another nice touch is the CommandFeed, which lets you feed the line through at the touch of a button.
If you’re looking for a highly versatile cordless strimmer, this WORX WG163E 18V (20V MAX) is an absolute value for money. Apart from being able to convert into a min-mower or edger, it comes with two 20V batteries to offer unlimited power, something absent with most other cordless strimmers.
And unlike many other models that utilise a bump feed system, this one features a CommandFeed function, which allows you to get more line from the spool by simply pressing a button. Even more, this strimmer is ultra-lightweight considering its 3.5kg weight. The DEWALT DCM561P1S is around 7.4 kg, so you can imagine that contrast.
Edge trimming is also possible with this strimmer because of the adjustable head plus the wheels that enable it to go into tight spaces such as under garden furniture. Although some users said it can be a little tricky to convert from trimmer to edger, this grass strimmer is still a bang for the buck.

Unlike most strimmers that use a cutting line, this model used a unique sharp nylon cutting blade which has a 25cm cutting width. This gives a more efficient cut when compared to line strimmer models. Ideal for all types of strimming and trimming jobs around the garden, from strimming around paths, along fences or around the edges of borders and lawns.
Other features include the 180° adjustable trimmer head that enables you to quickly switch to edging when trimming around the edges of lawns etc. A very versatile model, great for trimming in the tightest spots in the garden.
It has a safety guard which is important as well as a plant guard to protect your plants when strimming around them, which is another useful feature.
To ensure it’s well balanced and comfortable to use for all gardens, it has an adjustable telescopic handle which can be set between 850 – 1140mm, along with an ergonomic design, soft-grip handle and lightweight design.
It comes complete with 10 blades (9 spares), more can be purchased if needed at a very affordable price and it comes complete with a 2 years manufactures warranty, for peace of mind.
We’re a big fan of ‘VonHaus garden tools’ and have already reviewed their cordless hedge trimmer and cordless rotavator and they always impress, as well as being very reasonable prices. This strimmer is no different, and if you have a small garden, you want to keep it neat and tidy, this may be what you’re looking for.
The telescopic handle is a great feature, especially for smaller gardeners as you can adjust the height to suit you.
I was impressed with the nylon blade which works great when tidying around the garden, the adjustable head is another welcomed feature making trimming edges very easy.
It should give around 30 minutes of strimming but we found that around 20 minutes was about right, even so, this is probably more than enough for smaller gardens.
What it’s NOT suitable for
Despite all our positive comments, we did find that it does struggle with tougher jobs. Because of this, we feel its best suited to keeping the garden neat and tidy every couple of weeks, rather than starting to cut down long grass and brush in gardens that have not been maintained for a long time.
One concern we did have is we felt that the blades may need replacing on a regular basis, however it does have 9 spare blades and the replacement blades can be purchased in packs of 20 and are not expensive. You can see the replacement blades here.
Overall an excellent entry-level strimmer for maintaining the garden and at a price you would not expect.
One other important point, it does come with 2 years warranty, which is great news as it shows the manufactures do back up the quality of there products.
6. Bosch ART 30-36 Li Cordless Strimmer
Great for all tough strimming jobs that other models can’t do
- Robust heavy-duty design.
- Powered by a very powerful 36 V / 2.6 Ah lithium-ion battery.
- Lightweight design at only 4kg when compared to other heavy-duty strimmers.
- Cuts for approximately 35 minutes from one charge and can be recharged in only 90 minutes.
- Uses a twin nylon cutting line, for a more efficient cut, especially when strimming tough brush.
- 30cm cutting width, ideal for large-sized gardens.
- Plant guard to protect plants when strimming around them.
- 2 years warranty which can be extended to 3 years by registering online.
Bosch is known for there quality garden tools and they manufacture a number of cordless strimmers and this Bosch ART 30-56 Li cordless strimmer is one of their larger heavy-duty models, designed with large gardens in mind and for tougher strimming where less powered models may struggle.
Powered by a 36c / 2.6Ah lithium-ion battery, it will easily cut through the toughest of brush and long grass in larger gardens.
Like other Bosch models, it uses a Bosch Syneon Chip which intelligently controls the energy and power required for the type of strimming your currently doing. At the cutting end, it uses a semi-auto feed twin line feature which gives it more cutting power as it has two cutting lines, unlike most other models that only have one.
The ergonomic design and adjustable auxiliary handle ensure that its comfortable to use, even when used for longer periods of time.
We have reviewed a few Bosch power tools including garden shredders, cordless lawnmowers, hedge cutters and they all way seem to impress and are always very well manufactured. We looked at a few different Bosch strimmers in the past and we have never been that impressed with them, however, when we first saw the Bosch ART 30-36 Li strimmer we knew that this was about to change.
It’s very well made, rock-solid machine, its worth mentioning that it’s only really designed for strimming large gardens and will strim anything you put in front of it, from tough brushwood to long grass.
One great feature we do like is the plant protector, which means you can strim around plants without worrying about damaging them.
What it lacks
As it’s only designed with strimming in mind it does lack a few features some gardeners might prefer.
Firstly unlike most other models, it does not have an adjustable head which means you can not use it for edging. Another feature it does not have is a telescopic handle to adjust the height.
Overall it’s a great strimmer, especially if you have a large garden and need a strimmer capable of strimming through tough brush and long grass, then this is probably one of the best models for the job. One charge lasts around 35 minutes which we found would be enough for most larger gardens and the battery can be recharged in 90 minutes. If you have an extra-large garden or field to strim, it may be a good idea to invest in a spare battery.
What you need to know when buying a cordless strimmer
The number one consideration will be ‘what batteries do they use’, this can be a little confusing to understand at first as they don’t all use the same batteries and some models are available with different batteries, this can have a large impact on the price of the strimmer.
Look for models powered by Lithium-ion batteries – They have longer run times, much shorter charge times, with many fully charged within 60 minutes and they do not lose their charge like other types of batteries do.
TRY TO AVOID MODELS THAT ARE NOT POWERED BY LITHIUM-ION BATTERIES.
We do recommend one model that is powered by a NiMH by Flymo but we made an exception for this model due to good rating and performance.
Understanding lithium-ion batteries
The best cordless strimmers are available with a range of different battery sizes, most cheaper models are powered by 12v lithium-ion battery, but these are less powerful, have shorter running times and are only really suitable for small gardens.
There are also models which are powered by 18v, 24v and 36v batteries, these models have plenty of power, and are often comparable to main powered and petrol strimmer in terms of performance and power.
Voltage (v) & Amp Hour (Ah) – What it means to you
If you look carefully at which battery they come with, they will state the ‘voltage’ (v), generally the higher the voltage the more powerful the strimmer will be. It will also state the ‘Amp Hour’ (Ah), they usually start are 1.3Ah and go up to around 4Ah, the higher the rating the longer the running time is. This is the main reason the price can vary so much between models which appear to be very similar.
Generally the higher the voltage (v) and Amp Hour (Ah) the heavier the model will be, so sometimes more is not always better or even needed.
It really comes down to what you plan to use it for and how long for.
Take the recharge time into consideration
One of the main advantages to lithium-ion batteries is there ability to charge quickly, usually between around 1 hour and 3.5 hours depending on the battery.
Unlike older batteries, lithium-ion batteries can be recharged before the battery is flat, with the old Ni-can batteries, doing this damages the batteries but with new lithium batteries, this is not the case and they can be charged at any time, they can also hold their charge for long periods of time which means they can be stored over winter and will have a full charge when you get it out after a long periods of time.
This means no getting your strimmer out, only to find the battery has gone flat over winter which use to be a common event.
If you have lots of strimming to do, consider buying a second battery when you buy your strimmer, as they are often cheaper than if you buy it separately at a later date.
Best Cordless Strimmers Conclusion
We actually started by looking at over 15 different cordless strimmers and it quickly becomes clear that lithium-ion batteries were the way to go, prices ranged from around £50 for a nice entry-level model for small gardens, to well over £300 for a cordless model that was capable of strimming tough growth in a larger garden.
Which strimmer is best for you, will largely depend on what you intend to use it for and how much strimming you need to do.
We hope you’ve enjoyed and found value in the products above. Cordless strimmers have come a long way and the models available these days are more efficient and affordable. Moreover, their batteries charge fast so even if you can’t complete a job with one charge, you can always resume within a short while. Whilst the cordless strimmers in our list are of the highest quality, our favourite is the BLACK+DECKER 36 V Lithium-Ion Strimmer with 2.0 Ah Battery. With two modes of operation, E-Drive technology, 8500rpm and weighing 3.5kg, we felt it offers the most value compared to the others.
The strimmer has an impressive 30cm cutting swathe which further highlights how suitable it is for large gardens. The full cutting speed of 8500rpm is also second to none. At 3.5kg, it’s one of the most lightweight cordless strimmers on the market and coupled with a telescopic handle, it should be a lot easier to use than many other heavyweights.
