WORX WG163 GT 3.0 20V PowerShare 12″ Cordless String Trimmer & Edger
A tool that performs way better then its price tag and the first contender on our list is the Worx WG163. The price tag alone on this weed eater makes it a great deal.
As well as a great price tag, though, this is a machine packed with features and quality. It is a dual trimmer/edger, which means you get two tools in one machine. It has an extendable telescopic handle that is adjustable to suit your height requirements and utilizes Worx 20v batteries.
These batteries perform surprisingly well across the board, they stand up in the face of the bigger brands like DeWalt and hold their head high. Many people like to stick to one brand, Worx rewards you by for doing so by allowing you to use their batteries across a range of their tools.
The build quality here is also extremely good, the adjustable handle and plastic grip feel good in the hand, and it isn’t overly heavy. It comes in the standard black and orange color scheme and looks as good as it performs.
With its innovative push-button command feed system, changing the spools is made extremely easy. The rubberized internal wheels support the edger, which gives you smoother cleaner lines. The spacer guard is adjustable to give you that little bit more precision when working close to plants and flowers. The head also tilts to 90 degrees for those tough to reach places.
There are a few downsides to this unit, however. The wire spools on it are relatively small, and this means that you will be wearing down your lines pretty quickly. This means over the long term, and you may spend a little bit more with this unit, replacing the wire spools. This is offset by the cheap cost of the unit to begin with, however. Just something to consider.
- Very good value for money
- 2 in 1 trimmer / edger
- Adjustable telescopic handle
- Works with any Worx 20v batteries you already own
- Adjustable spacer guard
- Head adjusts to 90 degrees
- The wire spools wear down quickly due to their size
BLACK+DECKER LSTE523 Li-On String Trimmer
Black + Decker has a reputation for quality when it comes to the tools they produce. The LSTE532 is no different. Perhaps the most aesthetic tool on our list, the bold look of the LSTE523, gives it a professional feel. Luckily that professional look isn’t just for show, and this really is a professional offering.
Built with a high-quality battery system, this machine is made to run all day. The 3mAh system gives you a really long run time. The power delivery is good, and although you won’t be able to fell trees with this bad boy, there isn’t much else that will be a problem.
The thing that really makes this unit stand out from the rest is the ridiculous amounts of features it is packed with. With their EasyFeed system, all you need to do is push a button on the trigger to make more spool extend. Compared to a lot of “bump feed” systems, the EasyFeed system, just works, and works well.
There is also a Powerboost and Powercut setting on the unit. This allows you to turbocharge the cutting potential of your eater to tackle particularly stubborn areas. If you are dealing with areas that you have left for too long, ones that are more jungle than yard, the PowerBoost option will give you the muscle to deal with it.
As well as those amazing features, the LSTE523 comes with a lot of the great features that its competitors have. You can adjust the telescopic handle to match your height and reach, you can set the guard to protect your borders, and it converts from trimmer to edger instantly.
The unit does have a couple of downsides, however. One being that the EasyFeeder, can cause you to get through spools quickly. Users are reporting that although the EasyFeeder is a great innovation, you just have to be careful, or you will be spending lots on new spools.
The second gripe is that when you are not using the PowerCommand buttons, the unit can feel a little underpowered. Whether that is because users are comparing the cutting ability to when the PowerCommand option is on or to other units, is unknown.
- Feature-rich unit
- EasyFeed system works really well
- PowerCommand buttons provide you with a quick boost of power for hard to deal with areas.
- 2 Speed controls allow you some flexibility
- Works with all B+D 20v batteries
- 2 in 1 Edger/Trimmer
- EasyFeed system uses a lot of spool
- Can feel under-powered when not in PowerCommand mode
Greenworks 12-Inch 40V Cordless String Trimmer
Greenworks are another big player in the gardening equipment industry. Their range of tools are loved by a lot of the gardening community, and it’s easy to see why. This 12-inch weed eater is no different.
One of Greenworks best selling points it the interchangeability of its batteries. Every tool in their range uses the same system of batteries, and this can make purchasing their tools a lot cheaper than the competition as you can opt for a bare unit, one that doesn’t include battery and charger, as you already have them.
This unit is no different, running off Greenworks powerful 40v battery system, you should easily be able to get 40 minutes of usage out of the BST4000. Another great thing about their batteries is their potential for quick charging, one 40V battery used to power this trimmer can be charged from 0-100% in just 30 minutes.
Greenworks have embraced the change to brushless motors with open arms, most of their range now sport brushless motors. Brushless motors benefit from a longer lifespan, a better cutting potential, and a much more efficient application of torque.
With the two-line design model, which is the design with the best ability to cut, and the wide 16″ cutting swath, you should be finished with your garden and lawn jobs in record time. You can even up the power for when you are dealing with those stubborn areas.
Greenworks have taken a shot at the gas-powered string trimmers, which have long held the crown as the best when it comes to weed eaters. The problem has always been delivering the same level of power from a battery. With advancements in battery tech, that gap is closing, and it is closing fast. Not only are battery-powered tools nearly as powerful as gas ones, they emit much less noise, emissions and have a lower vibration too.
The front-mounted motor is great for weight distribution, and the handles and grips are designed with ergonomics in mind, this makes using the Greenworks extremely comfortable and easy, even during prolonged periods of use.
As always, nothing is perfect, and this unit does have some small flaws.
The power of this trimmer means that even with Greenworks awesome batteries, you will run your batteries fast pretty quickly. If you have small jobs to do or a second battery, then this is not an issue.
There have also been claims that the batteries have a problem that means they degrade, although, in our experience, this has never happened.
- Light and comfortable to use
- Strong cutting power
- Large 16″ cutting swath
- Brushless motor
- Rapid charge batteries
- Low battery life
- Claims of battery degeneration problems
DeWalt DCST990H1 40V MAX 6.0 Ah Lithium-Ion XR String Trimmer
Another eater in the high power bracket, DeWalt, produces some of the best tools on the planet. They are a staple for both DIY use and commercial/trade use alike. They were the ones to bring brushless motors into the mix.
This high-powered weed eater is designed to take on its gas-powered brothers, and we have to say, it is the best on this list at doing so. Although it doesn’t match a gas-powered tool in toe to toe power, the innovation and tricks that the DeWalt uses, bridge the gap excellently.
DeWalt batteries are second to none, their batteries charge rapidly, hold a great charge, and don’t degrade over time. A fully charged DeWalt battery is going to give you the longest run time of any battery too.
At only 12lbs, one of the main advantages to this unit is its low weight, coupled with its huge power output, and you get a unit which is easy to maneuver while still being devastatingly effective. It creates hardly any noise, and you do not need to leave it idling like a gas-powered model. It is also very easy to start, not needing a cumbersome pull cable.
The trigger on this unit is just another example of how innovative DeWalt are when it comes to designing tools. As well as being able to change the power settings, you can also control the speed that the motor is spinning with a reactive variable speed trigger. The harder you push, the faster it spins, this gives the whole unit a similar feel to using a gas-powered one.
The ergonomics on this model are simply great too, the grip feels comfortable, and the weight is shifted just perfectly through the tool. The telescopic pole adjusts to whatever size you need it to be too.
Another massive plus to this unit is the low power setting, unlike lots of its competitors, the low power setting on the DeWalt is still extremely effective. This means you can save battery life, without the tool losing its cutting ability. Light weeds and grass will never require you to move out of the low setting. On the low setting, you can often get up to 1 hour of use out of one fully charged battery, which places this unit at the top when it comes to battery life. If you already have DeWalt batteries, you will be able to buy just the bare unit at a great price too.
When it comes to tougher, harder to deal with tasks, you can up the cutting power just by squeezing harder. This kicks the motor into high power mode and will allow you to destroy anything in front of you. Paired with the large 15″ maximum cutting swath, jobs just get done faster with the DeWalt.
DeWalt tools are industry-leading when it comes to durability too. Their tools are rugged and made to take a beating. With things like their patented gear drive and industry-leading brushless technology, this is something that will last you a long time.
The downsides to this unit are tiny compared to the positives, but it still has a few. The guard is not the most well-designed guard we have ever seen and does not do the best job at preventing small stones from pinging off while cutting. It is easy to buy a better one, although it is annoying you have to do so.
Again, there are some complaints that their batteries range in quality. Some users swear by the DeWalt lithium ion battery system. Some people advise you to buy a brand new battery as some of the ones that are supplied in the kits may be of lower quality.
This is a battery-powered weed eater that holds its own easily in a commercial setting and is just overkill for DIY garden use, beautiful overkill.
- Highest powered unit on the list
- Innovative speed trigger gives incredible control
- Large 15″ cutting swath
- Very lightweight for its power
- Batteries provide a great run time
- DeWalt quality
- Guard is ineffective
- Battery quality may vary
CRAFTSMAN V20 String Trimmer / Edger CMCST910M1
Crafstman’s addition to the battery-powered weed eater market is the v20 string trimmer. This is another dual line model, which makes light work of grass and weeds.
The speed provided by the v20 battery pack is impressive on this tool; this means it makes light work of almost any challenge you could throw at it.
The motor on this unit powers the spinner at a blistering 9000 rotations every minute. This is one of the highest speeds reached by any battery-powered weed eater we have reviewed so far.
The 12-inch cutting swath isn’t as impressive as the DeWalt, but it is still large enough to make dealing with larger areas a breeze. The fact that the unit only weighs 5.5 pounds adds to that ease. You aren’t going to get as tired using the Craftsman as you would some of the other bulkier trimmers on the market.
The variable speed trigger is similar to the DeWalt, although it does not have the same responsive feedback, it still works really well. Paired with the high-speed brushless motor, this is definitely not a tool to be underestimated.
The telescopic handle rotates 180 degrees and extends, and this allows you to set the tool however you want. The two handles are well designed and placed ergonomically. All in all, the
Craftsman is perhaps the most ergonomic model on this list, so if you are looking for something that puts ease of use first, this may be your best bet.
The head of the unit has three different levels of tilt, making angled work a breeze. The edge guard on this unit is also one of the better ones on the list, and you can cut in confidence, knowing very little is likely to ping off.
Craftsman has always made very durable tools, and they stand by this by offering a three-year warranty.
The downside to this unit is the bump feeder for the spools. Craftsman has tried to create an alternative to the auto feeders seen on most models on the market. Unfortunately, the bump feeder does not quite hit the mark. It works, but we honestly don’t feel like it is an improvement over traditional auto feeders.
All in all, Craftsman has created a tool that excels in some areas but not in others. If you want a high powered unit that weighs surprisingly little, this could be the best tool for you.
- High speed
- Great adjustability
- 3 Year warranty
- The bump feeder is awful.
EGO Power+ 15″ 56-Volt Lithium-ion Cordless Brushless String Trimmer with 2.5Ah Battery and Charger
Like lots of their other tools, the EGO Power is pretty impressive. Sporting the usual neon green-gray and plastic trim with a carbon fiber shaft, it just looks fantastic.
Aside from the awesome looks, the EGO Power is just as impressive when it comes to performance too. It comes at a great price too, which is lowered to an even better price if you already own some EGO batteries.
It comes with a variable pressure trigger similar to the DeWalt, which gives the EGO Power a similar control and feedback to a gas-powered model. The motor stops when you let go of the trigger, too, which is a nice feature for those who are used to idling gas-powered monsters.
The Powerload feeder, is one of the best on the market. Loading up your string into this unit is amazingly simple. All you do is feed one end into the trimmer head and hold it with some tension, then press the powerload button, which will cause it to wind back into the head. They knew what they were doing here, and they have managed to turn the worst part about using a trimmer, into something that is no longer a chore.
In terms of ergonomics, you can tell a lot of time has gone into the design and placement of the motor. The whole unit feels extremely well balanced, and it isn’t too heavy or light at either end.
The power is great, too, using a brushless motor system to provide power that is constant and efficient.
Unfortunately, this is another unit where the stock guard needs to be improved. You may get some fly off when using the EGO, which is a shame for unit that scores so highly everywhere else.
- Awesome feeder system
- Great ergonomics
- Best aesthetic design on our list
- Works with all EGO batteries
- Guard needs improving
- Batteries are expensive
Milwaukee M18 Fuel String Trimmer
The final offering on our recommendation list comes from the tool juggernaut Milwaukee. This tool runs on Milwaukee’s m18 battery system. This means you can use batteries you already have for other Milwaukee tools.
If you buy this tool in the kit, it will come with the highly praised 9.0 amp battery.
With two-speed settings spinning at 4600 and 5800 rpm respectively, you also have control over the power with a variable trigger system. This allows a great level of control over what you are doing.
The over-mold grip on this unit is one of its best selling points. It is probably the comfiest eater on the list to use. The support handle is comfortable and soft without using foam.
This is great as you get a better grip without compromising on comfort. IT absorbs a high level of vibration too. It is also one of the quietest weed eaters on the market.
Changing your line with this tool is a nice easy, straightforward process too. Simply remove the spool and wind the line around.
Unfortunately, this model is not attachment ready. This means that you cannot use this tool as an edger as well. This is not a problem for most, but if you need a 2 in 1 unit, we suggest you look at some of the other options on this list.
- Milwaukee’s high level of quality
- Excellent battery system
- Uses the best quality batteries on the market
- Very quiet
- Best grip on this list
- Not attachment ready
Hopefully, we have helped you make your decision with our above reviews. If you are still undecided, these are the factors we look at when reviewing the tools. You can use these to help you make an informed decision on the best battery powered weed eater for you.
One of the main reasons people swap from gas to battery and immensely important is the products weight. One of the main selling points for battery-powered tools is that they are almost always lighter then their gas-powered brothers. A lot of the units on our list, for example, weigh under 10lbs!
Weight is important, whether it’s a 10-minute job or a ten-day job, the less the unit weighs, the less tired you are going to get wielding the tool.
Not all battery-powered options are created equal, however, and many of the offerings on the market are heavier than the ones we have suggested. If this is the case, they will usually be using an older batter system. If this is the case, stay clear. Old nickel batteries, weigh more, hold less charge and deteriorate much quicker than modern lithium-ion ones.
One of the biggest reasons people are unwilling to adapt to battery-powered tools is the old misconception that battery-powered tools aren’t as powerful. For a long time, this was the case, but nowadays, thanks to the advancement in lithium-ion batteries and brushless motors, that gap is closing rapidly.
If you are looking to buy a tool for anything less then the most strenuous of commercial use, we highly recommend going with battery power. Ga
When it comes to battery power, a unit is normally measured in volts. The most common are 20v and 40v. 40v models are the more powerful of the two, but they often come with a faster drain on the battery. If you are willing to buy a couple of spare batteries, you should probably go for a 40v model.
If you only need your weed eater occasionally or for a small job, stick to the 20v tools. They are usually more than enough to get the job done.
Lithium-Ion batteries are the future, and we recommend everybody to only buy battery-operated tools that have swapped to the new system.
Bear in mind, however, that not all lithium-ion batteries are created equal. The brands on our list: DeWalt, Black, and Decker, Ego are all known for being industry leaders in the innovation of technology. Their batteries are all great. Lots of less reputable companies, however, use low-quality lithium-ion batteries, these degrade quickly and lose charge surprisingly quick.
When it comes to battery life, you need to work out what is going to be best for you. If you need a high powered tool and a long battery life, chances are you are going to have to buy multiple batteries.
DeWalt and Milwaukee have the best battery life batteries, but they come at a higher price tag than their competitors. Deciding the best cost x performance is going to be key in deciding what tool you choose.
If you do not need a long battery life but need a powerful tool, then you can buy a kit that includes one battery and a tool with a 40v or higher rating.
If you don’t need the most powerful tool or battery life, go for the more budget-friendly options on our list. They still all perform amazingly in most tasks, the battery life may just be less impressive than the higher cost models.
Of course, another important factor will be whether you already own batteries for any of the brands. If you already have 3 EGO Power+ batteries, it makes sense to buy the EGO, etc.
Another thing to bear in mind is charge time. Some of the more innovative battery systems boast a 0-100% charge in under 30 minutes. With the average battery life being 45-60 minutes long, this means you only need two batteries to keep constantly working without any down-time for battery charging.
Most people do not consider the quality of the guard when it comes to choosing a weed eater. When you have a tool spinning at over 5000 revolutions per minute, you do not want to be hit by pebble traveling at that speed.
As well as your own safety, if you are working near your priceless mustang or a house with many windows, making sure your guard is effective is extremely important.
On the other hand, with a bigger, more protective guard, you also add weight to the unit. This means that if you are focused on getting a weed eater that is as light as possible, you may have to trade off on the level of guard protection. If you don’t mind a bit of extra weight, you should probably opt for a unit with a better guard.
Another thing to bear in mind is that usually, with units that are 2 in 1 trimmers and edgers, the guards will usually be less effective in edge mode.
Feed Loading Mechanism
If you have been using weed eaters for a long time, you will know that the worst thing about them is usually trying to feed more string into their mechanism. With gas-powered weed eaters, this has always been a horrible, awkward task.
Luckily most battery-powered tools come with better innovations across the board. This applies to the feed loading mechanism too.
Automatic feeds are the new thing, replacing the old manual style in most of the new models of weed eater. This is a great feature that will allow you to spend a lot less time fiddling with the line and more time actually using the weed eater.
Some models extend line as it detects it is needed, which is awesome. Others use a bump feed method where you bump the head onto a hard surface to force it to eject more line.
Some models still use the older system for setting line by hand, but you won’t find any models like that on our list.
So Which Battery Powered Weed Eater is Right For Me?
As you can see, this isn’t a question that has a simple answer.
When it comes to choosing power tools nowadays, you really have to figure out what you want from them. Firstly we would advise you to figure out what you really need your tool to do. Figure out how often you will need it, how long you will be using it for, and do some research on the area you will be using it on. Will it need to deal with stubborn weeds, or is it just for grass?
Once you have worked out these things, you will be able to work out how powerful of a unit you will need. You will also know what sort of battery life you will require. Use these answers and you should be able to remove a lot of the potential options from the market. You may have a few options left, at this point, you have a few options. You can either go for the one that performs the best, or the one that is the cheapest. Because you have already narrowed it down to only include tools that are suitable for your needs, either way, you will get a weed eater that will be able to handle your task.
One thing to bear in mind is future-proofing. Try and think ahead a little and decide whether it is worth spending a little bit more to ensure that the tool is up to not only the task you need it for now, but also any task you could potentially face in the future.
Battery-powered weed eaters produce zero-emissions and are increasingly cheap. They are designed to get at the edges of your lawn and hard to reach places such as steep hills.
