This weed wacker is an excellent value for money if you don’t have especially difficult weeds to cut through, but for bigger tasks, a dual-line model will serve you better like the Greenworks reviewed next.

Greenworks Corded String Trimmer at a Glance:

  • Cutting Width: 15 inches
  • Power: 5.5 amps
  • Design: Dual auto-feed line

  • Power: 5.5 amps
  • Design: Dual auto-feed line
  • Weight: 6.5 Pounds
  • Other4-position head adjustment

At the budget end of the price range, but with a wide cutting path and a tilting shaft, the Worx WG119 offers good versatility for a low price.

One drawback is that it doesn’t have an edging wheel, which would make it one of the best all-rounders on the market. However, you get a lot of convenience from the tilting head which can be used in four different positions.

While this doesn’t make up completely for the lack of an edging wheel, so if that is a deal breaker we have several others that do include one that ill fit the bill.

Even at a bargain price you get a telescopic shaft, which can be adjusted for anybody’s height, saving your back from having to bend over.

Remington Lasso String Trimmer / Edger at a Glance:

  • Design: Dual auto-feed line
  • Weight4.4 Pounds
  • Other: Edging wheel

The Remington RM115ST, like the Worx WG119, has that all-important telescopic shaft, but offers an edging wheel as opposed to just having an adjustable head.

It also features a 180-degree rotating handle that adds even more comfort in areas that are difficult to reach.

Another thing that makes this one of the easiest to use trimmers on our list is its featherlight weight. At just 4.36 pounds, it is the kindest to your back and means you can trim for extended periods with less fatigue.

The edging application is a nice touch at this low, low price, so the Remington RM115ST gives you surprising quality for what you pay.

In summary, only the most professional gardeners out there would be able be able to find any significant faults with this weed wacker!

  • Weight: 7 Pounds
  • Other: Split-shaft for equipment switch out

As the most expensive corded electric trimmer on our list, the Craftsman 16” has to offer something extra to remain competitive with the others.

With a 16 in cutting swath, it’s the widest one available, making shorter work if your weeding needs than a 13 or 14 inch model. It’s also one of the most powerful electric string trimmers, with a 10 amp motor, but this also translates into a slightly heavier unit.

To help compensate for the heavier weight, Craftsman includes a shoulder strap that makes it easier to use, especially for extended periods of time.

If a huge cutting path is what you’re after, you’ll find it here. With the Craftsman name you can be assured it’s one of the best electric weed wackers!

It is available with both a 2Ah or a 4 amp hour battery, so depending your edging needs there is one for you.

The battery works in all other Greenworks outdoor tools like their lawn mowers and leaf blowers so if you want to use their other lawn equipment you don’t need to get extra batteries or have separate chargers laying around.

To sum up, this model gives you about as much power as you’re going to get for a battery operated weed trimmer under $200.

While it does not come with an edging wheel what you do get is Dewalt’s legendary quality.

The DeWalt comes with the most powerful battery on our list at 60V! Combined with a 3 amp hour battery you have some serious week whacking at your disposal!

It has two power settings, the low one is enough for most work while prolonging battery life, and allowing you to save battery life and use the higher setting for tough areas.


BLACK+DECKER POWERCOMMAND String Trimmer/Edger at a Glance:

  • Cutting Width: 12 inches
  • Power20V / 3Ah
  • Design: Single line
  • Weight6.3 Pounds

If you have a lot of edging to do they offer a package deal with two batteries so you can just swap them out when one runs low.

Being on the lower end of the power scale at 20V, it doesn’t have the power to cut through tough weeds like the 60V Dewalt does. So make sure if you go with the B&D you have less challenging edging needs!

With a name like Black and Decker you know your getting a quality battery powered string trimmer and at a bargain price, it’s the best budget cordless weed eater on our list.

  • Design: Single line
  • Weight: 9.9 Pounds
  • Other: Can be run as 18V or 36V

Going in the opposite direction, the Makita XRU09PT is the most expensive string weed wacker on our list. The Makita is not for short, casual use like the B&D above.

It’s twin 18 volt batteries give you 60 minutes of run time on the lowest of the two settings. The Makita Constant Speed Control minimizes speed reduction where other models would slow down trying to cut stubborn weeds, the Makita chops up anything you throw at it.

Makita claims the XRU09PT is the best cordless string trimmer and with good reason. It outperforms many gas models but with the added advantages of low maintenance, less noise and no fumes.

If you want a heavy duty, no nonsense machine to rip weeds to shreds in an instant, this is the trimmer for you. The only real downside is the price, which is quite steep compared to everything else on our list.

Milwaukee Electric Tools String Trimmer Kit

Milwaukee Electric Tools String Trimmer Kit at a Glance:

  • Cutting Width: 16 inches
  • Power: 18V / 2Ah
  • Design: Single line
  • Weight: 9.9 Pounds
  • Other3 Year warranty

As you’d expect from Milwaukee, the 2725-21HD wacker is a well-built, workhorse of a weed eater that gets the job done.

The battery life is especially impressive on this model, and like other brands, the battery and charger can be used for other products from the same company.

It is also surprisingly powerful for a cordless model, easily matching many corded electric and gas models.

The only downside we can find in this trimmer is its weight, which could be tiring for after a long period of time. However, with the telescopic shaft, you can adjust the battery powered weed wacker to make it as comfortable as possible for you.

How to Choose the Best Electric & Cordless Weed Eater

best cordless weed eater

With all tools, there are myriad factors that make one better than the other, or simply that make one more suited to what you need it for.

The clearest distinction between all of these string trimmers is between the corded electric models and the cordless grass trimmers.

This guide will address all of the specific factors that go into deciding which weed wacker you choose, while comparing the more general differences between corded and cordless models as a whole.

Factors to Consider:

One of the most important questions when choosing an electric string trimmer is whether to go for a corded or a cordless model.

There are quite a few considerations, as both have their advantages and disadvantages. Here I’ll lay out the main differences so you can decide whether to go battery powered or stick with an electric corded trimmer.

Power Source

Evidently, in terms of power, there are two major categories that electric weed eaters fall into. Mains power and battery power.

Mains powered electric weed wackers can run motors of around 5.5 to 6.5 amps for as long as you need. The higher power output, and limitless usage time have to be weighed against the disadvantage of having to be within a cord’s length of a power supply, but corded electric string trimmers undoubtedly provide better performance in the power department.

To make a comparison with battery operated weed eaters, you can look at the voltage. All of the corded models listed use a standard mains voltage of 120 volts. Compared to this, the cordless string trimmers range from just 18 volts to 60.

This is not to say that they’d be embarrassed in a side by side comparison.

The lithium ion batteries used in many modern power tools give corded tools a run for their money.

Top tip: Keep an eye out for warranties on cordless trimmers. Horror stories of short battery lifespans are not unheard of.

Adjustable Power

On many models, power can be adjusted during use. There are two main ways of achieving this.

A lot of models, such as the Greenworks 2101602, feature a trigger with a variable speed, so the amount of power depends on how firmly you apply pressure.

Another way, as is the case with the Black+Decker LSTE523, feature different power settings, so you can choose between extending battery life or upping the power for hard to shift areas.

The style you choose is very much down to personal preference.

Few users would require the entire spectrum of power that a variable speed trigger provides, so in terms of the range of power, both methods are more or less equal. However, one key advantage of the variable speed trigger is that you don’t have to worry about stopping to change settings. Simply apply a bit more, or a bit less pressure, and your trimmer will respond.


Corded string trimmers still undercut all other variations by a significant margin, so they are a good choice for infrequent use or if you’re trying to be thrifty.

Battery powered tools can be up to $200 more than their corded cousins in terms of price, so you should expect to fork out a bit more for the extra mobility and freedom.

In some cases, the cost of a spare battery can exceed the cost of an entire corded string trimmer, so if price comes before mobility for you, the decision is quite simple.

Duration of Use

This is a foregone conclusion in favor of mains electric weed trimmers. Simply being plugged into the mains gives you unlimited run time which will never be beaten by cordless weed eaters or gas models.

However, with advances in batteries and motors, the cordless weed wackers in this list will provide you with enough run time for most jobs. You can expect to get around an hour of run time out of these batteries. They charge quickly too, so although you may see charging as a hassle, it really doesn’t hinder the time you can work all that much.

To sum up, mains powered tools have an infinite amount of power, but it’s far from the case that battery powered tools will run out of juice when you’re halfway through your job.


If you need maximum mobility, battery is the way to go.

Whether it’s because you have a large yard, or simply because you’re just so over having to pull a cable this way or the other every 10 seconds, you’ll be much happier with a battery-powered trimmer.

Corded models generally come with quite a pitifully short cable to begin with, which is hugely restrictive if you don’t already have a heavy duty outdoor extension cord. Having said that, I’m sure there are plenty of people who have a small yard and a good extension cord who would say their corded string trimmer causes them no mobility issues.


Weight is an important consideration with tools such as weed trimmers. You often use the tool for extended periods of time and must keep it off the ground at all times.

If you have an existing back problem, I would recommend you to go for the lightest model possible. In general, as corded machines don’t need to carry a battery, they are lighter, but check the “at a glance” section of the reviews to find out how much each individual product weighs.

Edging Wheel or Rotating Head?

best electric string trimmer

Most trimmers double as an edging tool. To do this, you need to turn the head sideways, and there are two ways of doing this.

Some have an edging wheel, which runs along a solid surface, such as paving, while the trimmer does its work. Alternatively, you could go for a rotating head, which does the same job, but without the support of a wheel.

Most users prefer a wheel, as it takes some of the weight of your weed eater and gives you more control than a rotating head, which you need to use a bit more strength to control.


A line is the part which spins round and does the actual cutting. A lot of the corded models here have a dual-line system, which in general lasts longer than a single line system.

Lines will have to be replaced over time, but you can pick them up for a couple of dollars at most good hardware stores.

Telescopic Shaft

best cordless string trimmer

There is no real difference between corded and cordless models in this respect.

Although weed wackers are not particularly heavy, they can put a significant strain on your back when used for just a few minutes.

A telescopic shaft is a fantastic way of reducing pains and strains. Adjusting the length of the shaft, you can make sure you are consistently standing in an upright position.

Not all of the models on this list feature a telescopic shaft, so if you have back pains, or are taller or shorter than average, look for something like the Black+Decker LSTE523, which has an adjustable shaft as standard.


Electric grass trimmers are easy to use, but a lapse in concentration can cause nasty injuries.

These trimmers all come with a protective cover to stop the trimmer catching your legs and to stop debris flying off at all angles. However, there is always a possibility of an accident.

Because of this, you should take precautions with what you wear when using a string trimmer. Gloves, heavy duty boots, eye protection and long pants are the basic items you’ll need to put on before you begin.

FAQs For Electric & Cordless String Trimmer

best electric weed wacker
Greenworks 12-Inch 40V Cordless String Trimmer

Q: What about gas models?

A: As with all outdoor tools, gas models no longer rule the roost. Apart from being dirtier, harder to maintain and noisier, gas models only have a slight power advantage these days.

Q: Are batteries included for the cordless models?

A: Batteries are included with all of the best cordless string trimmers. With most, you can buy extra batteries, or use ones you may already have with other products from the same brand. All of the brands on our list that use batteries that can be used in their other outdoor equipment adding to the convenience by not having to buy separate batteries and chargers.

Q: How do I stop my line from breaking?

A: All lines will break over time, but a few tips for extending their life are:

  • Use a high quality line
  • Try not to let it come into contact with hard objects, such as concrete or fences.
  • Don’t let it become brittle in cold temperatures

Q: When should I choose between a battery powered or gas powered trimmer?

A: The choice between a gas or cordless model depends on two things. The first is how long do you plan on using it? If you just need it for 20-30 minutes a cordless model will be fine. Second, what are you cutting? A gas powered model is typically more powerful and will cut through thicker weeds and grass.

Q: How does a weed eater work?

A: A weed eater or string trimmer works by rotating a head with a piece of thick nylon cord at a high rate of speed. The rapidily rotating head spins the line so fast that it acts like a knife cutting through weeds and grass easily.

Q: How do I use a string trimmer?

A: Hold the trimmer at waist level while the head to the trimmer is a few inches off the ground parallel to it. Then slowly swing the head side to side letting it fully cut the weeds or grass. Don’t force it too fast through thick grass and weeds as it will bog down and most likly stall the trimmer. Once you are done, clean off all the trimmings so it’s ready to use next time.
