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.

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.

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!

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 Corded Electric & Battery Powered String Trimmer

best cordless weed eater
BLACK+DECKER POWERCOMMAND String Trimmer/Edger

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.

Price

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.

Mobility

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

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.

Lines

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.

Safety

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.

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:
