- Final Word
Cordless string trimmers offer plenty of benefits over their gas-powered or corded counterparts. Also known as weed eaters and weed wackers, the most obvious benefit is the freedom of effortless movement. With this string trimmer, you can move from one corner of the garden to the other without having to avoid trailing cables. Have you ever found the weed eater’s cords sagging or have accidentally cut through them? If you have, the cordless model is the ultimate solution. Of course, there are tons of other benefits. However, the focus of this article is on the best cordless string trimmer reviews.
Buying Guide for Cordless String Trimmer
Ultimately, the best cordless string trimmer is one that meets your needs. Do not be swayed by the glowing reviews or the features of a weed eater that doesn’t come close to addressing your needs. You should find one that is within your budget, comfortable to use and handles the task you want it to accomplish.
Given that a majority of cordless weed eaters are battery-powered, they are the best choices for tackling urban and suburban yards. However, if you plan to do a lot of trimming or have a very large lawn with stubborn grass, a gas weed eater might be a better option.
That’s probably the utmost important point when it comes to choosing your cordless string trimmer.
If your yard’s on the bigger side, you’ll be using your string trimmer for prolonged periods so weight is crucial. And it isn’t only about weight, it’s also about weight distribution.
The unit may be feather-light, but its overall weight may be badly distributed making you end up with a cramped shoulder after only a couple of minutes.
Another important aspect is the handle. Again, your unit may be so lightweight, but the handle’s in an awkward position that might ruin your entire experience.
Deciding on battery life is dependent on your yard’s size, and how much work you think it’ll need.
Most batteries that come with string trimmers have a battery life of 30 minutes or more. However, just like motor power, as the battery life increases, the unit tends to be more expensive. So I think you should opt for buying one that precisely would suit your yard work needs.
If you’ve got a small yard that’s manicured in 15 minutes, don’t go buying a unit of 1-hour battery life, it’s meaningless.
As for the battery power, the more it is the more your unit would be able to tackle tougher jobs. So an 80V powered unit would be much tougher than a 20V unit. Deciding which to go for is also dependent on how tough the work around your yard is.
Battery Charging Duration
Some batteries require many hours to fully charge, some charge right away. Decide on this depending on how long runtime is and whether it’d suffice your yard or not.
If runtime isn’t as long, and you’d require multiple charges to finish your yard, then it’d be so annoying and impractical to have a unit that takes hours to charge.
To understand cutting range, I want you to imagine a core with 2 strings protruding from it on both sides. That core is rapidly spinning, just like a fan, making it seem like a complete circle.
The cutting range is the diameter of this imaginary circle, measured in inches.
It may seem like bigger is better regarding cutting range, but you may want to opt for a smaller cutting range if you have rocks and fencing around your garden.
Speed Control Dial
That’s essential to maintaining your battery life. An on/off switch bumping your unit’s motor to its highest capacity will do nothing but drain your battery in no time.
Ideally, there should be a control dial in your unit so that you conserve as much energy as you could. Only use high settings when you need more power.
String trimmers also differ regarding the way strings are inserted into the unit.
Bump Loading Strings
Strings are wound into a reel that’s inside your trimmer’s head. These strings are consumed as you work through your yard.
When you notice your string’s lessened in length, you simply bump the head of the weed eater into the ground to release more string line through the spool.
However, when the strings inside the reel are completely consumed, you’ll have to open up the head and re-string the reel. This may be problematic for people who aren’t into mechanical stuff.
But generally, restringing the reel can’t get any simpler if you see how it’s done and give it a try.
Automatic String Advance Trimmers
There’s no manual work here, the unit does all the work for you.
Individual Loading Strings
These allow you to simply cut small lengths from your string package and insert them as they are inside the head of the unit. No need to bother with a winding reel or anything like that.
If the weed eater does not offer enough comfort during use, then you might not use it as often as you should. For the best experience, look for a cordless trimmer with an adjustable handle, cutting head angle, and shaft length.

How does a string trimmer work?
A string trimmer works based on the principle of centrifugal force.
When the string is spun rapidly, it becomes extremely stiff as the spinning core holds it alongside another opposing force that acts on it due to rotation. It becomes powerful enough to cut weeds and the like.
Is the string trimmer line biodegradable?
It’s mostly neither biodegradable nor compostable.
There have been some companies trying to produce biodegradable string trimmers to help prevent polluting yards with plastic bits resulting from trimmer use.
However, they aren’t as strong as standard plastic string lines, so I wouldn’t recommend them for the time being.
