If you own a yard, then chief among your priorities is keeping it looking beautiful and attractive for longer. If you require to do some weeding, then choosing a cordless string trimmer is what you need to keep in mind.
Regardless of whether you refer to these string trimmers as weed eaters or weed whackers, string trimmers will always remain essential to your landscaping tasks. When you pair them with the best lawnmowers, then you are better able to take care of any pesky details in your lawn. These string trimmers have been around for decades, with the earliest models being corded and gasoline-powered, with gasoline types offering the best efficiency and power – alongside the fumes.
There is a reason to be thankful for the many technological advances, as this has led to the development of cordless string trimmers today. They now have sufficient horsepower and efficiency to rival gasoline-powered trimmers, without the inhaling of gases and exhaust fumes. Other than that, many manufacturers today offer you a wide variety of tools that can allow for streamlining in your landscaping activities, as they share the same batteries.
Best cordless string trimmers – Comparison table
Greenworks electric corded string trimmer, 4 Amp – best for smaller lawns
- Adjustable telescoping shaft to fit the user’s height. Convenient cord lock to prevent accidental unplugging
- Lightweight construction
- Includes a 3 year warranty
- A shaft design that takes on a telescoping appearance
- 4-year warranty and a cutting path of 13 inches
- A dual-line, auto feed measuring 65 inches

Since this is an electric trimmer, it uses a power cord to power its mechanism. This also allows it to be less demanding in maintenance and run as quietly as possible. If you are struggling trying to deal with annoying batteries or gas fumes, there is no need to do so with this model – the only disadvantage is the limitation of the trim area, since its power depends on the length of the cord.
The power system also makes this trimmer ideal for a small lawn. In case you are dealing with very tough weeds, the trimmer uses a dual-line string system that boosts its efficiency, and the line feeds into the spool through an auto-feed mechanism. There is something to warn about though – you cannot tilt the trimmer head in different directions, which makes it hard to reach difficult places.
- Efficient to use and maintain
- Dual-mode to help in faster trims
- Telescoping shaft aspect
- It has good balance
- Its battery lasts for a long time
- Unsuitable for tall people
- The trimmer head is inconvenient when reaching difficult places

What to consider when choosing a cordless string trimmer
Before going ahead to spend your money on a cordless string trimmer, it is important to consider the factors we will discuss below.
Life of the battery
Most of the cordless trimmers you will find in the market have a Lithium-ion battery that operates the machine, with an average battery life of between 15 and 50 minutes. Similar to motor power though, the more expensive trimmers have batteries with a longer life – the more the voltage rating, the greater power the unit gets.
The Li-ion batteries are the best option if you want to purchase an electric trimmer that works for close to an hour of continuous operation. The recharge time will also depend on your requirements – ranging from 30 minutes at the least, to 2 hours at the most.
Is the unit durable?
The more durable trimmers need to have very strong material that can serve you for many years. It is important to know this and decide on it, and it depends on the length of running time, as well as whether it is enough for your lawn or not.
Certain models will also be completely quiet during their operation. If you need to carry out very intensive jobs, then choosing a unit that has a short battery life or very long recharge time will be impractical for you.
The weight of the unit
It is important to keep the weight of the entire unit in mind, which makes it essential to select the one you can carry easy and use it to maneuver around your lawn. If the lawn space is very big, then you need the trimmer for a longer time, so the weight goes along with that. Note that as the load of the machine goes down, the price will go up.
In addition, its balance is also important to consider, because some units may have poor weight distribution even though they are lightweight. If you choose them, it is easy to end up cramped and fatigued even after using the unit for a few minutes. Lightweight trimmers might also be a disadvantage in a larger lawn, or a space that has many plants you are dealing with.
The cutting path of the string
The string’s cutting path needs to be at a length you can use to clear up the areas in question in one sweep. It also needs to taper easily in tighter areas, and cover constricted areas as well. The usual length you will find in cordless models is 12 inches, although there are some that have a longer length.
In addition to the cutting path length, the shaft length is also good to keep in mind. This is because it determines much of the clipping removal, weight supply, and maneuverability. There is also a tendency of longer shafts producing more fumes, which is not necessarily the case for shorter shafts.
Regardless of the shaft length you prefer, you will need it to have an ergonomic grip, which will prevent sliding or other possible accidents during handling.
The power is also essential to consider – even more so than a corded trimmer. This is because the cordless trimmers use batteries, so checking the cordless trimmer battery type is important to keep in mind.
Hopefully, the list and criteria of the best cordless trimmers should assist you to make a good decision – and these choices will help you on where to start looking.
What are the differences between a nickel-cadmium and lithium-ion battery?
Many cordless trimmers today use a Li-ion battery, because they are more modern, compact, and lighter. The Nickel-Cadmium batteries are heavier and bigger, and tend to suffer from memory effects, where their voltage decreases over time.
What exactly is cutting swath?
This is the width of the trimmer to allow it to cut in one swath, so the larger cutting swaths can cut more vegetation. That does not mean they are better, because they can have challenges in handling smaller spaces.
Should I go for a cordless trimmer?
It really depends, although it will be preferable for you if you seek portability in your gardening tools. The main issue with them is that they do not last very long in battery life, and they are also unsuitable for very large lawns.
