In the world of cordless trimmers, you’ll find a wide price range, from £50 for basic models without a battery or charger to £350 for those heavy-duty, professional-grade machines. Your garden’s size plays a significant role in determining which trimmer to go for. If you’ve got a small plot with just a lawn or two, most cordless trimmers will do the job. But if you’re like me, dealing with larger areas or particularly stubborn grass and weeds, you’ll want something more robust as tested.

Battery Voltage and Capacity

  • Look for a strimmer with a high voltage battery, preferably 36V or higher, to ensure it has enough power to handle heavy-duty tasks.
  • Check the battery capacity (measured in ampere-hours, Ah) to determine how long the strimmer can run on a single charge. A higher Ah rating means longer runtime.

Many cordless strimmers rely on a single 18V or 20V battery, while the beefier models can run on two of these, giving you a total of 36V or 40V, or they might use a higher-voltage battery altogether. As for cutting width, simpler models might have a range of 21–25 cm, whereas the larger ones can go up to 30-38 cm. Trust me, this makes a world of difference when tackling hefty sections of unruly grass.

Cordless StrimmerAmpere CapacityBattery VoltageHoursCutting Width
Basic Simple Models2Ah to 2.5Ah18V or 20V30 minutes21–25 cm
Heavy Duty Models4Ah or 5Ah 36V or 40V60 minutes or longer>25 cm (30-38 cm)

Now, speaking from my own cordless strimmer experience, most of these machines typically come with an 18V-20V battery packing 2Ah to 2.5Ah capacity. This provides a decent runtime of about 20 to 30 minutes. If you need to keep going for an hour or longer, consider getting a trimmer that offers a 4Ah or 5Ah battery, even if it means a bit more weight to carry around. Some trimmers can also work with other batteries from the same ecosystem, giving you more flexibility.

If you’re in a hurry, like I often am, you might want to look for a strimmer with a quick charger. Charging times can vary, with some taking only about an hour to juice up, while others may require two, three, or more hours. It all depends on how impatient you are to get back to trimming!

Grass Cutter Operation: Line-Cutting and Blade-Cutting Methods

First off, let’s talk about line-cutting strimmers. These nifty machines house one or two lines of nylon string within the head. The magic happens when these strings start to spin fast; they stiffen up and act like blades, slicing through grass and weeds. However, when they’re at rest, they’re pretty much useless for cutting.

Now, the issue of replenishing the line can be a bit of a chore, but most cordless trimmers have mechanisms to make this task easier. You’ll encounter two basic methods: “bump feed” and “automatic feed.” With “bump feed,” you give the strimmer a gentle bump on the ground to release more line. It’s a bit like having control over when and how fast you use the line. On the other hand, “automatic feed” trims off more line each time you start the machine, ensuring you never use a dull line. But be cautious; this can sometimes lead to using up the line too quickly and costing you more.

Speaking from my own testing experience, if you’re using a cordless grass trimmer, you’re likely turning it on and off as you move around the lawn to save battery life. In this scenario, automatic feed might be less efficient as it keeps releasing a new line each time you start the machine. Some prefer the automated approach, but it can consume extra line.

Now, let’s talk about the cutting power. You’ll come across single-line and double-line trimmers. Single-line strimmers apply less cutting force compared to their double-line counterparts. The choice between the two depends on the task at hand. Some folks find double-line trimmers overly powerful, and they can even cause unintended damage to fences, flower pots, or tree trunks if you get too close.

Bladed strimmers are also gaining popularity. These usually feature two fast-spinning nylon blades on the head, providing substantial cutting power. However, you’ll need to change these blades every two hours of usage, as they can get damaged or even fall off in rare cases. Most heavy duty trimmers come with extra blades, and you can purchase replacement packs online.

From our testing experience, blades and cutting lines offer fairly similar cutting power. Some gardeners prefer blades because they’re tired of dealing with lines, while others dislike the hassle of changing blades. It often comes down to personal preference.

Moreover, Thicker and heavier lines can cut through tough grass and weeds but may also be trickier to handle heavy duty task and more prone to jamming, especially if you wind new line onto the reel yourself. Ready-wound replacement spools are sometimes available but can be costly.

If you’re dealing with weedy or challenging sections, look for trimmers that offer heavy-duty lines or blades. Some trimmers even have features like wheels and rotating heads that make edging and cutting around plants a breeze.


More power often means a heavier trimmer that can put extra strain on your arms, back, and shoulders. It’s essential to find that sweet spot between power and comfort, which might just come down to ergonomic design.

  • Consider the weight of the strimmer, as heavy-duty models can be quite substantial. Opt for a model with ergonomic design features like adjustable handles and a comfortable harness to reduce fatigue during extended use.

Einhell Power X

einhell power x heavy duty cordless strimmer uk

Let’s provide a testing perspective on the Einhell Power X Heavy Duty Cordless Strimmer in the UK, highlighting both praises and shortcomings.

My experiences with the Einhell Power X have been nothing short of excellent. Gone are the days of mixing fuel, dealing with spark plugs, and maintaining carburetors. With the blade attachment, this strimmer effortlessly tackles thick brambles and saplings. It powers through with minimal hiccups.

While the grass strimmer function might not match the prowess of a petrol-powered counterpart, it still gets the job done for most tasks. It only struggles with the thickest grass clumps, which might require a couple of passes. The bump feed system, which can be hit or miss on most strimmers, is par for the course, but that’s a minor quibble.

See picture below of our purchase.

One of the standout features is the noise level. The Einhell Power X is significantly quieter than a petrol strimmer, and the reduced vibration makes for a more comfortable experience. Plus, the convenience of starting it with just the push of a button.

Assembly was a breeze, and I didn’t need to consult the instructions even once. Some users have mentioned issues with the strap, but with a bit of adjustment and patience, I found it to be a comfortable and well-balanced addition.

While the Einhell Power X Cordless Strimmer certainly has its merits, there are a few areas where it falls short. Assembly instructions would have been appreciated to ensure that the setup is both correct and safe. Even though I managed to assemble it without much trouble, having clear instructions would eliminate any doubts about its safety.

On the positive side, the Einhell Power X feels robust and well-built. However, it does have a bit of weight to it, especially with two batteries installed. This can make it a tad heavy during prolonged use. Properly adjusting the harness helps distribute the weight more comfortably, but it’s essential to get this balance right.

Battery life is a mixed bag. While the two 3 amp batteries last for about 90 minutes, which suits my needs, it’s worth noting that they recharge in just 60 minutes. However, if you’re planning to use this strimmer extensively, consider investing in additional batteries or a battery starter kit.


bosch heavy duty cordless strimmer uk

As someone who’s familiar with the hassle of petrol-powered tools, I was pleasantly surprised by the Bosch Heavy Duty Cordless Strimmer. It’s incredibly user-friendly—no more fussing with petrol, struggling to start the engine, or enduring the smell of exhaust fumes and petrol on my hands. This machine means business and gets the job done with ease.

I recently had to tackle a patch of four-foot nettles, and this strimmer breezed through it in no time. I have a sizable garden, so the thought of investing in an extra battery (albeit a bit pricey at £120) or even switching to a Bosch cordless mower with interchangeable batteries seems like a worthy consideration.

Battery performance impressed me. With nearly continuous use, it lasted about forty minutes without overheating. After a quick seventy-minute recharge, it was good to go for another forty minutes. The auto feed feature worked like a charm, performing better than the bump feed system on my old petrol strimmer.

A significant advantage is the reduction in noise compared to a petrol strimmer. Plus, the minimal vibration adds to the overall comfort of use. And let’s not forget the convenience of starting it with the simple push of a button. I’m delighted with this purchase, and my old petrol strimmer is now destined for the scrap collectors.

While my experience with the Bosch Heavy Duty Cordless Strimmer was generally positive, there were a few issues to note. Upon receiving the package, I noticed that the tape on the original packaging had been broken, and a new Bosch original sticker secured the box. The parts appeared new, but the battery seemed used. This raised some concerns, and I’ll have to test it to see if it functions correctly.

Additionally, it’s important to mention that the Bosch Heavy Duty Cordless Strimmer might feel a bit heavy after about thirty minutes of use. It’s not a deal-breaker, but it’s worth considering, especially for users who plan on prolonged strimming sessions.

Greenworks GD40BCK2X

greenworks gd40bck2x heavy duty cordless strimmer uk

Assembly was a bit of a challenge, taking my friend and me about an hour to put together. The primary hurdle was the unclear instructions, but once we got it assembled, it proved to be straightforward to use.

While it might be considered a bit underpowered by some standards, I found it to be generally efficient for my needs. It handles typical strimming tasks with ease. The real test came when I switched it to the brush cutter function, which took around 20 minutes the first time. I expect it will be much easier on subsequent attempts.

Battery life is respectable, offering about 20 minutes of operation on a single charge. Fortunately, the package includes two batteries, effectively doubling the runtime to around 40 minutes in total. This ensures I have enough power to complete my tasks without interruption.

Overall, I’m quite pleased with the Greenworks GD40BCK2X. It appears to be well-manufactured and surpasses the performance of cheaper models I’ve owned in the past. Plus, the convenience of a cordless strimmer is a significant improvement over petrol-powered alternatives.

There are a few downsides to consider. As mentioned earlier, the assembly instructions leave much to be desired. They could certainly be clearer and more user-friendly.

Another issue that cropped up in my experience is the absence of the advertised blade in the package. This was a disappointment, and I had to source the necessary blade separately to handle tougher cutting tasks.

Lastly, the machine itself is not the lightest, which can become noticeable after about thirty minutes of continuous use. However, for most users, this might not be a significant drawback.

Gtech HT50

gtech ht50 heavy duty cordless strimmer uk

I recently acquired the GTech HT50, and it has proven to be a lightweight and easy-to-operate tool for our grass edge trimming needs. This is actually the second GTech machine we’ve purchased, and the previous one served us well, offering reliable service over time.

One of the standout features of the GTech HT50 is its solid cutting blade. Unlike models with plastic wire cutting mechanisms, the blade on this strimmer excels in terms of performance. It not only does a better job but also saves us the hassle of dealing with finicky wire changes. The efficiency and ease of changing the blade make a significant difference in our trimming tasks.

While it’s true that the GTech HT50 may come at a slightly higher price point compared to similar models, the quality and performance justify the investment. It’s a durable and efficient machine that simplifies our grass trimming tasks.

While the GTech HT50 has many merits, there are a few areas where it could be improved. Some users may prefer a line strimmer over the blade system, as they find that the blades can break or fly off relatively easily, especially when edging. This can lead to frequent replacements, which can be inconvenient.

Additionally, the lack of a guide for edging makes it challenging to achieve a neat finish when using the GTech HT50 for this purpose. This may require some extra effort and patience to get the desired results.

Another consideration is the battery performance. Some users have noted that the battery doesn’t seem to hold its charge well when not in use. While it may not be a significant issue for those who use the strimmer frequently, it can be a drawback for occasional users.

Yard Force

yard force heavy duty cordless strimmer uk

I must say, it’s a powerhouse of a machine. The brushless motor impressed me with its maximum power and efficiency, making it a reliable tool for tackling various lawn trimming tasks. Whether it’s cutting through thick grass or tidying up the edges, this strimmer gets the job done with ease.

One of the standout features is the included 2.5Ah 40V Lithium-Ion battery. Not only does it provide ample power for extended use, but it’s also compatible with other items in the GR40 series, offering versatility and convenience for those who have other Yard Force tools. Plus, the quick charger ensures that you spend less time waiting for the battery to charge and more time working on your lawn.

The Yard Force Heavy Duty Cordless Strimmer is designed for precision and convenience. It comes equipped with multi-position wheels that add stability and make edging a breeze. I found this feature particularly helpful when navigating uneven terrain or creating clean edges around flower beds and shrubs.

Additionally, the adjustable cutting width, ranging from 28 to 33 cm, is a thoughtful addition. It allows you to customize the cutting width to avoid plants, flowers, and garden décor, ensuring that your lawn stays pristine without unintentional damage. This level of control adds a layer of efficiency to the strimming process.

While the Yard Force Cordless Strimmer has many impressive features, it’s essential to consider a couple of aspects. The power and effectiveness are undeniably great, but this strimmer may not be the ideal choice for users with very large lawns or extensive trimming needs. The battery life, while decent, may require occasional recharging for more substantial tasks.

Additionally, while the multi-position wheels offer stability, some users may find them a bit challenging to adjust, particularly when switching between different positions. A more user-friendly adjustment system could enhance the overall user experience.


worx wg927e heavy duty cordless strimmer uk

To start, I want to express gratitude to DPD for their efforts in ensuring a second delivery attempt, despite a slightly bashed box. The mower and strimmer pack arrived intact and ready for action.

Assembling the machine was a breeze, especially attaching the arms, which was straightforward. The collapsible grass box was also easy to put together. At first glance, the mower may seem a bit flimsy compared to my old electrical lawnmower, but it surprised me with its durability. While it’s not as lightweight as expected, it offers robust performance in return.

One standout feature is the ease of maneuverability. Once you get it going, the Aworx WG927E is effortless to navigate across your lawn. The safety key is a great addition, providing peace of mind during operation. It handled even mildly overgrown grass with relative ease, though it’s recommended to avoid using it on wet grass to prevent jamming.

I was particularly impressed when I adjusted the cutting height to the second lowest setting. It transformed into a grass-cutting powerhouse, significantly reducing the time required to complete the task. With a garden size of 20×25 feet, I managed to finish the job with just one charge. Although the batteries ran out towards the end, I might have been a bit harsh with my expectations. It’s still early days, so I’m keeping an open mind.

Overall, I would wholeheartedly recommend the Aworx WG927E. It appears to be a robust and efficient choice for lawn maintenance tasks, offering a hassle-free and cordless experience.

While the Aworx WG927E has several praiseworthy features, it’s important to consider a couple of drawbacks. The battery life, although decent, may not be sufficient for users with larger gardens. If you have extensive trimming needs or a spacious lawn, you might need to invest in additional batteries to ensure continuous operation.

Additionally, the machine may encounter some challenges with longer grass, so it’s advisable to keep your lawn well-maintained to prevent any hiccups during operation. Some users might also find it slightly cumbersome to carry.
