Weed Eater Reviews

Black+Decker LST300 Weed Whacker

For the first entry on our best electric weed eaters list, we are going to be looking at a weed eater from a brand that definitely needs no introduction. If you have ever used a power tool before, then you don’t need to be told who Black+Decker is.

They are one of the premier makers of tools of all different kinds. This includes, among other things, lawnmowers, chainsaws, and yes, weed eaters. So, we figured that a great way to start off our review list would be by taking a look at the Black+Decker LST300 Weed Whacker.

For starters, this is a cordless, battery-powered weed eater. As with any weed eater of this type, one of the first things that you need to look at is how long the battery lasts. After all, nobody wants to have to deal with a battery that is constantly dying in the middle of a job.

Thankfully, this isn’t going to be an issue that you encounter with the Black+Decker LST300 Weed Whacker. In fact, the Black+Decker is equipped with a 20-volt lithium-ion battery pack. This battery pack is really high-quality, and it provides more run time than a lot of other, comparative battery packs do.

While power isn’t of too much importance when dealing with weed whackers, it is still something to give some consideration towards. The power output of the Black+Decker is fairly decent thanks to the presence of a PowerDrive transmission. This gives the Black+Decker enough power to easily complete most jobs in a reasonably quick time frame.

Something that we are going to place a high emphasis on during the course of our best electric weed eaters list is versatility. You want a weed whacker that you can adjust to fit the current challenges facing you.

Again, the Black+Decker LST300 Weed Whacker does very well in this regard. It can be easily converted from a trimmer to an edger in mere seconds. Likewise, the handle (which is already pretty well-made and surprisingly light) can be adjusted to help make the weed eater easier to use.

  • Highly adjustable handle.
  • Can be converted from a trimmer to an edger.

  • PowerDrive transmission ensures that the tool is equipped to handle any job.

  • Long-lasting lithium-ion battery pack.

  • Not the most durable unit around.

Greenworks 13-Inch 4 Amp Electric Corded String Trimmer

For the next review on our best electric weed eaters list, we have something really good to show you, which is the Greenworks 13-Inch 4 Amp Electric Corded String Trimmer. If you are familiar with Greenworks products at all, then you probably already have a very good idea of what to expect from this weed eater.

All Greenworks products tend to be both inexpensive and energy-efficient. As you will see, this is definitely the case with this particular weed eater.

While we have reviewed some fairly affordable weed whacker options so far, in terms of pure affordability, it is hard to top the Greenworks 13-Inch 4 Amp Electric Corded String Trimmer. At well under $30, the Greenworks is an extremely inexpensive option that can still hold its own with some of the pricier, higher-end weed eater options on the list.

Likewise, Greenworks is an extremely efficient machine as well. Weed whackers aren’t exactly known for being energy hogs or anything like that, but they do still use energy, especially if you are frequently using the tool on your lawn.

So, you might care that the Greenworks 13-Inch 4 Amp Electric Corded String Trimmer uses a lot less energy than a lot of the other weed eaters that you have seen reviewed on this list.

Something else of note is that the Greenworks Weed Whacker is incredibly lightweight. It weighs just around 7 lbs. That makes it one of the absolute lightest options around. It really helps to save you from back and muscle pain after a long session of cutting the grass.

  • A very energy efficient model.
  • Extremely lightweight.

  • Decent performance.

  • One of the most affordable options out there.

  • Cord can be a bit annoying to work with.
  • Not as durable as some other models.

WORX WG163 Cordless String Trimmer & Edger

Moving on with our look at the best electric weed eaters, we have a truly high-end weed eater to show you in the form of the WORX WG163 Cordless String Trimmer & Edger. This is a very high-quality weed eater that is sure to become a staple of your lawn cutting chores for a very long time.

A big part of what makes the WORX WG163 Cordless String Trimmer & Edger such a good weed eater is its overall quality. This is a very reliable weed eater that you can trust is always going to get the job done.

One unique feature present on the WORX WG163 Cordless String Trimmer & Edger that we haven’t seen so far is the presence of an instant line feed. As the name indicates, this feature lets you quickly and easily feed in more lines.

This is done with the simple press of a button. This makes it a much easier process than on basically any other weed eater on this list.

In fact, the only real issue that we can levy against the WORX WG163 Cordless String Trimmer & Edger is the fact that the battery life is lacking a bit. However, this isn’t too much of an issue when you consider that, in addition to the tool itself, the WORX also comes with an extra battery.

  • Comes with two batteries.
  • Powerful 20-volt battery.

  • Can act as both a trimmer and edger.

  • Easy push-button system for feeding in more spools to the whacker.

  • Individual battery life isn’t great.

EGO Power+ Lithium-Ion Cordless Brushless String Trimmer

The next product that we want to show you in our best electric weed eaters article is yet another really high-quality, durable, and reliable weed whacker.

The EGO Power+ Lithium-Ion Cordless Brushless String Trimmer may not have the same brand recognition as Black+Decker, but maybe they should, given the sheer quality of this particular weed eater.

For starters, this is one of the most powerful, if not the most powerful entry, that we have reviewed on our best electric weed eaters list. The EGO Power+ Lithium-Ion Cordless Brushless String Trimmer, as the name indicates, is equipped with a brushless motor. Now, if you have used power tools before, then the term “brushless motor” may mean something to you.

These are often put on high-end power tools and they are a good sign that the tool that you are about to use is powerful and reliable. The same applies to the EGO Power+. The brushless motor on the weed eater helps to ensure that it is capable of dealing with any lawn trimming job. It also ensures that you can cut through thicker pieces of grass with relative ease.

In terms of durability, the EGO Power+ Lithium-Ion Cordless Brushless String Trimmer definitely impresses. It is built to last for quite a while, even if you use it quite frequently.

Furthermore, it is also built to resist the elements. Now, we know that you aren’t likely to be out there trimming your grass when it is raining or anything like that. But, it is still nice to know that the Ego Power+ was built to resist things like water damage and damage from other types of weather.

Something else that the EGO Power+ Lithium-Ion Cordless Brushless String Trimmer does quite well is giving you control. The tool is equipped with a variable speed trigger, which means that you get a lot of control over exactly how fast the string goes. This can make very precise cutting a lot simpler.

  • Variable speed trigger for precise cutting.
  • Durable and weather-resistant.

  • Powerful brushless motor.

  • Durable aluminum grip and shaft.

  • Can be tricky to replace the spool or perform other maintenance.

DEWALT DCST920B 20V XR Brushless String Trimmer

For the final review, we are going back to a big brand by reviewing the DEWALT DCST920B 20V XR Brushless String Trimmer. We are sure that in an article looking at tools we don’t need to introduce DEWALT, as they are a brand that you are all likely familiar with.

The DEWALT DCST920B 20V XR Brushless String Trimmer is the sort of high-quality tool that you would expect on this list and from such a respected manufacturer. The weed eater is very powerful as it is equipped with a well-made brushless motor.

Likewise, the DEWALT is also equipped with a wide array of really useful features that you have been exposed to elsewhere on our list, such as a variable speed trigger, which is great for making sure that all of your cuts are accurate.

  • Comes from a very reliable brand.
  • Well-made brushless motor.

  • Variable trigger for greater accuracy.

  • A fairly pricey weed eater.

Weed Eater Buying Guide

Weed eaters (also often referred to as weed whackers or string trimmers) are pretty common items that are found in most garages across the world. However, have you ever wondered what truly goes into picking out a high-quality weed eater (like the type found on our best electric weed eaters list)?

Well, we are here to answer that question. In this buying guide, we will explain to you some of the most important criteria for you to keep in mind when shopping for a weed eater.

Why Electric Is Your Best Option

The very first thing that we want to cover as part of this buying guide is exactly why we choose to only focus on electric weed eaters. Those of you familiar with these tools will probably also be aware of the fact that weed eaters can come in gas-powered models, as well as electric ones.

So, why did we choose to only review electric models? Well, the simple answer is that when it comes to weed eaters specifically, they are just the much better option for a few reasons.

First off, while it is true that electric weed eaters are less powerful than their gas counterparts (in general, gas-powered tools are almost always the most powerful option), that doesn’t really matter when it comes to weed eaters, does it?

These are precision trimming tools and so having a lot of raw power doesn’t matter quite as much as it does with say lawnmowers. So, the main advantage of going for a gas-powered weed eater is already somewhat pointless.

Electric models come with their own wide set of advantages that need to be acknowledged as well. For example, electric weed eaters are a lot quieter than gas models.

They don’t whisper quiet or anything like that, but when compared to the loud noise created by gas engines, electric models are definitely a lot easier on the ears.

Another pretty big advantage of electric models is their cost and reduced maintenance needs. While electric models can sometimes cost a bit more upfront, those costs will be temporary as electric models don’t require anywhere near the same amount as gas models do in the long term.

This is because electric models are both more reliable and you don’t have to buy fuel. This is going to be very noticeable if you are one of those people who are constantly working on their lawn.

Likewise, the best electric weed eaters are likely to require a lot less maintenance than gas weed eaters for the simple fact that electric models have fewer internal components. Gas models need extra components inside to both store and process the fuel.

This is not the case with electric models, whether they be battery-powered or corded models. Whenever a tool has fewer parts moving inside, it becomes a lot less likely to break down.

What You Need To Know About Electric Weed Eaters

In this part of the buying guide, we are going to cover some of the things that you need to keep in mind when shopping for a weed eater. These are roughly the same criteria that we relied on when assembling products to feature on our best electric weed eaters review list above, so you know that it is reliable.

Straight Shaft vs Curved Shaft

Weed eaters can be straight shaft or curved shaft.

Straight shaft models are more suitable for tall people. Their design allows you to mow without bending or squatting.

Shorter people are more likely to prefer a curved shaft weed eater as it is easier to hold and maneuver. Its design makes it easier to keep the cutting elements perpendicular to the grass.

If you have never used a weed eater, we recommend that you take a closer look at them in a store and see which of the two types will be more comfortable in your hands.

Protective base

It is mounted behind the cutting part of the weed eater and thus there is no direct access to the blades, as well as the risk of solid particles flying backward. Keep in mind that some protective bases are larger and can limit visibility when operating.

Possibility to strap

Some weed eaters have straps in the kit that attach to the base and allow you to strap them. This makes the weight of the weed eater easier to bear and the mowing more precise.

Mowing diameter

The wider the cutting diameter of the weed eater, the faster you will process larger areas. Gasoline models usually have a wider cutting diameter than cordless and electric models.

Battery Powered vs Corded

Like pretty much every other electrical power tool out there, electric weed eaters come in two major kinds, ones that operate on batteries and ones that are corded. Of the two, battery-powered options are the best for those who value mobility and convenience.

They may also be essential for those who are not fortunate enough to have a plug close by to their lawn. Corded weed whackers are better for those who want some more power or who don’t mind the presence of the cord and just want the convenience of never having to charge a battery.

Run Time

If you do go for a battery-powered weed eater, then one of the top things to consider is the run time of the tool. Nothing is worse than being in the middle of trimming your lawn or bushes and then having the tool die on you.

The number one way to prevent this is to invest in a tool with a long run time. A more expensive alternative to this problem would be to either buy a tool with multiple batteries or to invest in a separate battery on your own, which should let you alternate.

Adjustable Handles and Heads

As you saw from many of the reviews on our best electric weed eaters list, by far one of the most important things that you can look for when shopping for a weed eater is adjustability. Ideally, you want a tool that can be easily adjusted to fit your needs.

So, this means getting one that has both an adjustable handle and an adjustable head. Both of these features will make adjusting to cuts at different angles a lot easier. They will also make using the tool a lot simpler and easier on your back.

Is there any difference between a weed eater and a weed wacker?

In short – no! When it comes to design, work, and purpose – there is no difference between a weed eater and a weed wacker. Even in most physical and online stores, you can find machines under both names.
