12 Best Cordless Weed Eaters

When it comes to cordless weed eaters there are 3 main factors that everyone wants to know; power, battery life, and weight. Finding the right balance of all 3 at an affordable price is not easy, which is why we have created this cordless weed eater guide.

Advantages of Cordless Weed Eaters

Cordless weed eaters have risen in popularity over the last decade, due mostly to the improvements in battery technology, making them a viable alternative to gas-powered.

  • Mobility. When compared to corded weed eaters, cordless ones are great if you have a large yard that needs to be maintained without having to invest in an extension cord and drag it around whenever you are trimming weeds.
  • No Fuel Mixing. Unlike 2 stroke gas weed eaters, you won’t need to worry about mixing fuel correctly just to get the engine running, just plug in the battery and go, it’s that simple.
  • More Reliable. Another factor with electric-powered weed eaters that people often overlook is that there are more things that can go wrong with a gas-powered weed eater compared to an electric-powered one. This is mostly due to the fact that there are simply more moving parts in a combustion engine so parts are more likely to wear out or break.
  • Electricity is Cheaper than Gas. Recharging your weed eater battery is significantly cheaper compared to filling up your gas weed eater. Also, gas, if left for long periods of time, will degrade and won’t be any good at all. So if you rarely use your weed eater then an electric powered is a better choice.

Finding the Best Cordless Weed Eater for Your Needs

Don’t go spending hundreds of dollars on a top range weed eater if you are only using it for 30 minutes each week. It’s much better to buy one that is suitable for the type of weeds you will be trimming and the amount. So unless you are a professional gardener/landscaper or have a large amount of space that needs trimming regularly then you shouldn’t be spending more than $500 on a weed eater.

You also need to think about whether you can make use of any extras for your weed eater, like attachments for extending the reach of the trimmer, or a model that can twist and cut lawn edges easier. These can save you lots of time, especially if you were doing them with various tools before.

Best Cordless Weed Eaters

1. Black & Decker LST136W

This weed eater is extremely popular and my personal favorite, with a very good rating on Amazon and some decent specs for a weed eater that comes at an affordable price. It’s also pretty compact, light and packs a punch for a string trimmer.

The LST136W comes in two types, the 36 volt, and 40 volt, so if you feel that you might need a machine with just that little bit extra power then the 40 volt is what you should go for. The battery will give around 45 minutes of trimming time which should be enough for most people, but you can always get a second battery to double that if you need it.

The only downside to this model is the lack of attachments, which doesn’t take away from the fact that it’s a great string trimmer. An added bonus of getting a Black & Decker weed eater is the batteries are compatible with other Black & Decker tools. So, if you already have a compatible battery, you can buy just the trimmer without the battery and save some money.

2. Core CGT400 CGTSD

With so many letters and numbers in the name, you’d think this model was something special, and honestly, it is. With some serious power behind it, the CGT400 cuts like a gas weed eater and even looks a lot like one except without the noise and weight.

As for attachments this model also doesn’t come with any, but looking into other products made by Core they have a special power unit that is designed for multiple attachments, so if you are looking for a range of garden tools that are interchangeable then it may be worth looking into the ‘Power Lok’ range.

The run time of this model is pretty impressive with 70 minutes of run-time per charge and variable power control. In terms of price it isn’t cheap but is in the same range as a quality gas weed eater, so if you are looking for a good electric weed eater then check this one out.

3. Black & Decker LCC420

Another Black & Decker, but they’ve got all the basics right with this model, and it comes with a leaf blower too, which is great for keeping your driveway and paths clear during fall and winter. As for the trimmer, it’s not as powerful as the CORE above but still punches above its weight for a 20V.

It has a run time of around 60 minutes if you run it in the more efficient power mode, but if you are tackling some thick weeds then it will be less.

One feature of this model that I think more weed eaters should have is the edging wheel, which makes edging so much easier than doing it freehand and it’ll stop the trimmer eating through the string.

As for the price, this model can usually be picked up for under $150 and is worth every cent. In fact, I think it would be difficult to find a better weed eater for any less!

4. Dewalt DCST990H1

The Dewalt DCST990H1 is a string trimmer that delivers the same performance as a gas model, but with the convenience of being cordless. With a high capacity battery, generous cutting swatch and a patented gear drive, this trimmer is tough enough to get the job done quickly.

Powered by a 40V, 6.0Ah lithium-ion battery, the DCST990H1 offers 50% more battery capacity than its competitors. The improved battery capacity combined with the trimmer’s generous 15” cutting swath allows you to get the job done much faster. With the DCST990H1, you can easily clear thick weeds and grass in just one pass.

If you’re concerned that a single battery won’t get the job done, Dewalt offers additional batteries, so you always have at least one spare on hand.

The trimmer’s brushless motor allows for an even longer runtime and life. The energy transfer is automatically controlled by the motor, which lets the trimmer run for longer in between each charge.

Because the DCST990H1 is powered by battery, there’s no need to deal with mixing gas or difficult start-ups. Simply pull the trigger, and get started.

The gear drive design is another feature that’s unique to the Dewalt line of trimmers. Not only does it amplify the torque, but it also allows you to maintain the same cutting speed even when under heavier loads.

With a variable speed trigger, you have more control over the trimmer’s power. The Hi/Lo speed control also allows you to manage the trimmer’s run time more efficiently, and make adjustments to ensure proper performance.

The bump feed head features dual 0.080” line, which also gives you control over the feed rate. Ultimately, the DCST990H1 is all about giving the user complete control over how the trimmer performs.

Housed in a heavy-duty aluminum case, the DCST990H1 is highly durable and can withstand professional usage.

The DCST990H1 trimmer comes with a battery, charger, pre-wound 0.080” line, auxiliary handle and guard.

Pros

  • Just as powerful as a gas trimmer
  • Easy to start with a simple pull trigger
  • Comes with pre-wound string
  • Can tackle tough weeds with ease
  • Extended battery life
  • Generous size cutting swath can clear weed and grass in one pass
  • Heavy-duty aluminum casing adds durability

Cons

  • A little heavy and bulky

The only gripe with this trimmer is that it’s a little heavy and on the bulky side. That makes it a little difficult to use the trimmer in tighter places. That being said, heavier weight is to be expected with a trimmer that has this much power and battery life.

All in all, the Dewalt DCST990H1 is an excellent trimmer and a smart choice for homeowners with larger yards. The extended battery capacity will allow you to get the job done faster and without having to stop mid-way to recharge. With a powerful motor, this trimmer is on par with most gas models on the market today.

5. Dewalt DCST920P1 String Trimmer

Dewalt is a leading name in the power tool industry, and the DCST920P1 string trimmer is a testament to the quality this brand is known for. With a brushless motor, patented gear drive, lightweight and ergonomic design, this trimmer will get the job done without causing fatigue and without having to recharge mid-job. How well does it perform? Let’s find out.

Powered by battery, the DCST920P1 is a cordless, portable trimmer with a lightweight of just 8.5 pounds. Unlike other string trimmers, this Dewalt model won’t tire your arms – even if you’re taking on a big job.

The brushless motor offers optimal durability and motor efficiency. The DCST920P1 also provides very precise power control thanks to a variable trigger. The High/Low-speed control also gives you better run-time management.

Dewalt’s patented gear design provides more torque and makes it easier to maintain your preferred cutting speed under load. The bump feed head features dual 0.080” lines and a 13” cutting swath.

One of the main advantages of the DCST920P1 is that it’s powered by a battery. It doesn’t produce any fumes, and you won’t have to worry about mixing gas. It’s easy to start up, too, so you can get to work faster. The lightweight and ergonomic design of this trimmer makes it easy to use, and it feels balanced in your hands.

Edging will use up more battery power and eat up more string, but it does the job well. The only complaint is that the trimmer only has a minimal guard, which means you often have debris flying back towards you, so make sure you follow these safety tips when operating your string trimmer.

Pros

  • Powerful enough to tackle thick or deep weeds, brush or grass
  • Well-balanced; won’t cause fatigue
  • Lightweight design for easy use
  • Powered by a 20V battery (you can use any of Dewalt’s 20V li-ion batteries)
  • Comes equipped with tough, durable and ribbed string
  • Can easily perform light edging on the low setting to preserve battery life
  • Highly portable and cordless
  • Variable trigger allows you to control the trimmer’s speed
  • Generous size cutting swath for trimming larger areas

Cons

  • Batteries run out of juice quickly when running on the high setting

The only complaint with this trimmer is that the batteries die out quickly when running on the highest setting. While a little disappointing, this is really not surprising.

On the highest setting, the motor works harder and requires more power. Unless you’re running the trimmer on high the entire time, you probably won’t notice much of a difference in battery life.

The Dewalt DCST920P1 is a reliable, durable and powerful string trimmer that can tackle just about any job – big or small. It’s compatible with most 20V batteries, so if you already have a few on hand, you can start using this trimmer right away. All in all, it does a great job edging and trimming, and we would highly recommend this trimmer to any homeowner.

6. WORX WG160 Review – Lithium Grass Trimmer/Edger

The WORX WG160 is the ideal trimmer for small and large yards alike. In fact, this trimmer is also an edger and a mini mower all-in-one. This means that you can easily tidy up the yard and even cut missed grass in the process.

While mowing a large yard with this model may be farfetched, the features that are seen will be enough for any user that needs a quality trimmer/edger that can also double as a mower.

The dual-position wheels make it simple and easy to edge or mow. These wheels are also a welcomed addition for anyone trying to edge in a small space.

The lithium battery included holds its charge for the duration of your yard work needs and is backed with 20-volts of power. The battery holds a 20-minute charge and will recharge in just 3 hours.

There is a total cutting diameter of 12-inches. This means that you can trim faster than ever before. A single line feed is also seen and bumping is not a necessity.

You can adjust the height with the quick-release lever and the handle has 7 locking adjustments. This allows users to use this trimmer the way that is most comfortable for them.

You can quickly convert from trimmer to mower to edger in seconds without any tools. This means users are able to do yard work much faster and without the immense hassle of using 3 pieces of equipment.

Weight can be a concern when using any piece of yard equipment. The WG160 is not only the perfect weight, but it is also a mere 6 pounds and comes with wheels. This means this model can be used by grandparents, younger adults or just about anyone without becoming too heavy to carry.

Functionality is not an issue with the WG160 at all. The only minor fault maybe the 20-minute battery life. If you plan on trying to mow your entire yard with this model, you will need to do a lot of charging.

For those that simply want to edge, trim and mow their yard to give it a professional look, the WG160 is the perfect fit. Even with the short battery life, this battery far exceeds the competition and only takes 3 hours to fully charge.

The WORX WG160 is ideal for anyone that is on a budget but needs to have the utmost in yard trimming equipment. The 3-in-1 capability of the WG160 ensures that you can trim, edge or mow a yard with ease. The 12-inch cutting diameter makes the job move along faster and even the battery provides enough charge for most yards. With the ultra-lightweight of 6 pounds, this is an exceptional model that anyone can easily use.

7. Black & Decker LCC420 R

The Black & Decker LCC420 is a lightweight string trimmer with great cutting power. Powered by a Max Lithium-Ion battery, this model boasts an hour of run-time and is incredibly easy to use.

With the ability to convert to a trimmer, the LCC420 allows you to tackle most yard chores with just one simple piece of equipment. Let’s take a closer look at this trimmer’s features, its pros, and its cons.

Battery-powered string trimmers are more convenient than their electric and gas counterparts, but battery life tends to be an issue with most models. Black & Decker’s LCC420 trimmer features a 20V Max Lithium-Ion battery, which retains its charge five times more than other NiCd batteries and has a longer lifespan. Included with the trimmer is a 4.0 amp hour battery pack that allows for double the run time than the LBXR2020 battery pack. The LCC420 features a dual-mode accelerator switch that allows for one hour of use.

The gear-drive transmission of the string trimmer delivers great cutting power and allows you to get the job done quickly. The automatic feed spool makes trimming a breeze as there’s no need to bump the line or make manual adjustments.

Another great thing about this model is the fact that you can easily convert it to an edger. With just one tool, you can trim weeds and cut along your driveway and sidewalk to create a manicured look. Unlike other models on the market, the LCC420 is easy to start up and quiet.

This model also comes with a sweeper, which is lightweight and easy to use. The sweeper can help eliminate debris from your deck, patio, walkway, driveway or garage.

The Black & Decker LCC420 has the power to take on any trimming job, but this model is not without its faults.

The lithium-ion battery only provides one hour of runtime. While this is much longer than most other battery-powered trimmers, it can be an issue if you have a lot of yard work to do. Your best bet is to purchase a spare battery and keep it charged just in case you need more power.

Although the trimmer only weighs 12 pounds, it can become heavy after extended use. This tends to be an issue with any trimmer, regardless of whether the model is powered by electric, gas or battery.

Overall, the Black & Decker LCC420 is a great buy for homeowners that are looking for great cutting power and an environmentally-friendly trimmer. The included sweeper is also a nice added bonus that helps you clean up debris after trimming.

8. Toro 51467 Review – Trimmer and Blower Combo

The Toro Co 51467 is an entry-level blower/trimmer that includes a plethora of features into an almost unbeatable price.

While this is not meant for commercial use, this is an option for homeowners that want to take care of their yard and do so without having to hire a landscaper in the process.

Users that want to get started with their 51467 will love the no-tools design. Simply snap all of the parts in place, start up the trimmer and you are ready to go. There are no long waiting involved or complicated instructions.

The battery life is impressive with 45 minutes of runtime in one charge. The battery itself also alerts users when they are running low on juice. This is done with a red LED to alert users when it is time for a charge. A green LED means that there is more than enough power to go about your daily trimming.

The overall design is not only aesthetically pleasing but very functional as well. Users will not feel the aches or pains that they are used to with other trimmers. The ergonomic design allows users to strain less and cut through the thickest weeds with ease.

The feed is perfectly bumped so users never have to finagle with trying to get their line advanced again. This is one of the biggest strong points and makes using this model much more comfortable to use.

The lightweight of just 6.4 pounds and a safety shield are also a welcomed addition. Users will not get tired before the battery runs out and getting hit with rocks or roots is not an issue with the shield present.

The batteries with this model work great initially, but they seem to hold less of a charge after a few years of use. While many users can use this trimmer 2 – 3 times without a charge, others state that their batteries weaken over time and will only last 20 minutes.

The easiest remedy for this, and one that is highly recommended regardless of battery life, is to purchase an additional battery. This will not only allow you to achieve the full 45 minute trimming time, but a backup battery provides more flexibility for those times when intricate trimming is needed.

The Toro Co M/R 51467 is an extremely affordable trimmer that should be part of every homeowner’s yard work toolset. A powerful motor, a long battery life, and a very comfortable design will ensure men and women alike can use this model with ease.

9. Makita LXRU02Z LXT

Unlike other models in this price range, Makita has ensured that this model starts quickly.

This is a relief for anyone that has spent 10 minutes trying to get their trimmer to start before. The refill line is simple and the power is great.

The LXT is a cordless trimmer that allows the utmost in flexibility and features a new design that ensures users can trim with precision. The trimmer is well-balanced, allowing for maximum leverage, and the motor is exceptional.

Let’s examine some of this model’s features to see why the LXRU02Z is highly recommended.

There is a lot to like with the Makita LXRU02Z LXT. This model is powerful, sleek and affordable. The biggest benefit seen is the powerful motor and very user-friendly design. Users will find that the grip and basic control of this model are outstanding. Users can trim their yard for hours without feeling back pain or sore in the process.

This unit weighs under 7 pounds, so a normal 20 – 30 minute trim will not cause any issues. Batteries charge very quickly with this model. In just 30 minutes, you are ready to trim again. This is ideal for bigger yards or those that simply want to fine trim/edge their yard.

Some users have complained that the height is too short for them. This may be a preference, but we saw no issues with this model’s height. There is a strap for anyone that needs to bend over a little more to gain proper leverage.

The battery life is ample for a smaller yard, but not great for extremely large yards. The only solution is to either allow the battery to recharge (which is super-fast), or to buy another battery. The latter is the best option and allows for longer trimming without the hassle of recharging.

Makita has produced one of the most affordable trimmers on the market. With a 7,800 RPM motor, this model is both powerful and efficient. The adjustable head is a great addition and will allow users to trim or edge easier than ever before.

For home users, this is the perfect model that allows both ease-of-use and a plethora of features. Cutting is easy, the trimmer is lightweight, and the battery charges extremely fast.

10. Core CGT400

When it comes to cordless trimmers, the Core CGT400 CGTSD is one of the best-rated models on the market. With long battery life and powerful trimming capabilities, this model is a great investment for homeowners looking to make the switch from gas to cordless.

Unlike other battery-powered trimmers, this model actually boasts enough battery life to trim the entire yard with just one charge. Even if 70 minutes is not enough time to finish the job, charging time is a mere 3 hours.

Because this model is powered by battery, there is no need to worry about harmful emissions. For those looking for an environmentally-friendly trimmer, this is your best choice.

The Core CGT400 CGTSD is also lightweight and well-balanced to make trimming as comfortable as possible. Heavier models can be difficult to maneuver and exhausting to use. This model makes trimming weeds a breeze. As an added bonus, this model requires little to no maintenance.

One of the Core CGT400 CGTSD’s biggest strong points is its power. It boasts 25% more torque than a 25cc dual-cycle trimmer. The model also features a dual-line bump feed with a 20-inch spool.

For added peace of mind, this model comes with a 5-year warranty for residential use and a 2-year warranty for commercial use.

The Core CGT400 CGTSD is one of the highest-rated cordless trimmers on the market, but there are some customers that had a few minor complaints.

Some users found that for heavy-duty jobs, the battery runs out quickly. However, for everyday maintenance, the battery life is more than enough for the average homeowner to trim their entire yard. While some did not like the 3 hour charge time, it is significantly less than other cordless models on the market.

Another customer had an issue with their battery not being able to recharge. While this is cause for concern, this is an issue that plagues any battery-powered trimmer. That particular customer did receive a replacement from the manufacturer, which resolved the issue.

Overall, the Core CGT400 CGTSD is an excellent buy for homeowners who are looking for a powerful cordless model. This model is exceptionally quiet, lightweight and can easily get just about any trimming job done with ease. Its affordable price tag also makes it a better buy than many other models on the market.

11. Black & Decker NST2118

The Black & Decker NST2118 is an updated model of the previously discontinued Grass Hog NST2018. This cordless model features the Black & Decker PowerDrive Transmission for improved power. It also comes with two batteries to ensure that you have enough power to finish the job. Backed by a two-year warranty, the NST2118 is a great buy for a homeowner looking for a lightweight, effective trimmer.

The NST2118 comes with two 18-volt NiCad batteries, which means you always have a fully charged battery on hand for extra-long jobs. As an added bonus, you receive an external battery charger, which plugs right into any ordinary household outlet. Best of all: The charger is Energy Star qualified. This means that charging your battery won’t run up your electric bill.

Each battery has a lifespan of approximately 30 minutes. Between the two, this should give you an hour of trimming time. Each battery takes roughly 9 hours to recharge.

Black & Decker’s unique PowerDrive Transmission drives more power from the trimmer’s motor to its cutting string, which will allow you to finish the job quickly. The NST2118 can also trim those hard-to-reach places your mower just cannot reach.

The biggest advantage of using the NST2118 is that it is lightweight and easy to use. At just 6.4 pounds, any homeowner, regardless of their size and age, can use the trimmer. The adjustable handle also helps to make this model user-friendly as it can be adjusted to suit any height and job.

Because this trimmer is not powered by gas, it starts up immediately after you pull the trigger. This eliminates some of the frustrations that pull-start trimmers tend to have.

Another added bonus is that the model is cordless. While having to deal with extension cords isn’t necessarily a deal-breaker, it can be a major inconvenience. Without this restriction, you save time and have the freedom to move around your yard.

One thing that many people dislike about battery-powered trimmers is that they can run out of power relatively quickly. If you have a larger yard, this can be an inconvenience. The NST2118 comes with two batteries. If you rotate the two batteries and always keep one charged, battery life should not be an issue.

This model does seem to have some minor issues with larger weeds or bigger clumps of grass. However, it can still get the job done.

One minor complaint that some users have is the battery’s short lifespan. While it is true that the battery typically lasts no more than 30 minutes, if you keep the other battery charged, this should not be an issue. For edging and trimming, one hour should be plenty of time.

Although the model is not without its imperfections (what model isn’t?), users are more than happy with this trimmer. Its lightweight and ergonomic design make it easy to use. The fact that the model is cordless also gives users plenty of room to freely trim and edge without the constraints and hassles of extension cords.

12. Black & Decker LST136

Black & Decker is a company that does not need an introduction. The brand is known for affordability and durability. This is something that the Black & Decker LST136 definitely adheres to.

Not only is this model great for trimming, it is also cordless. This means less time fiddling with gas running out or attaching extension cords. However, there is much more to this model than being merely cordless.

Powered by lithium batteries, this model is as good as its charge provides. Users with smaller to medium yards will find that the 36V provides a long enough charge to trim the entire yard with ease. Those with a lot of trimming to do, or that have a larger yard, will be happy to know that there is a longer-lasting battery available – 40V.

While the high voltage batteries are impressive, they do not match the two available cutting speeds. Quickly and easily switch between 6,500 and 8,500 RPMs. This will allow you to cut through thicker weeds with less hassle. The shaft is also adjustable which allows you to turn this trimmer into an edger within minutes. Now, you have the perfect 2-in-1 model that will ensure your yard looks professionally trimmed at all times.

The batteries are also very long-lasting and the average lifespan with moderate foliage is 45 minutes. Those with thicker foliage and using high speeds may see that their model lasts 20 – 30 minutes. This is more than acceptable for most uses and allows you to be free of cords or running low on gas.

By including a charge and spool, this model really stands out against the crowd. Not only is it built by a trusted name, but it provides an exceptional cut every time.

While it will be adequate for most users, those with exceptionally large lots or trying to use the LST136 commercially will find it doesn’t last as long as a tank of gas. The upgrade to the 40V battery or purchasing an additional battery is an option. The recharge time of just 1 hour also helps to make this fault negligible at best. Changing the power settings is also an option for increased longevity.

The Black & Decker LST136 far exceeds the user’s expectations. While it may be powered by batteries, the variety of power settings allow users to enhance their battery life, or simply cut as close as they want.

With the addition of a charger and an automatic feed spool, this is a simple model that anyone can pick up and use. There is no bumping involved which is also great for those that have never used a string trimmer before. With the product weighing just under 8 pounds, users will have an easy time trimming their yard or edging.
