Back in the stone age, basic scythes were used to cut down weeds and harvest crops, but using these tools took a lot longer, and needless to say, required tremendous effort.
Fast forward to today, we’ve got weed eaters aka string trimmers to do the exact same job in a fraction of the time.
Weed eaters are power tools that are fitted with a long handle, and a rotating blade that spins a string-like blade—most commonly a thin piece of nylon, which is probably the reason weed eaters are often called string trimmers.
Weed eaters are simple lawn care tools, but buying one can be a bit overwhelming, due to the myriad different models to choose from.
But after digging deep into this segment, I’ve narrowed it down to the 10 best cordless string trimmers that can make the job of maintaining your yard a whole lot easier.

Should I Buy a Gas Weed Eater or Cordless Weet Eater?
Gas-powered weed eaters are fitted with a motor that runs on gasoline and can either have a 2-stroke or 4-stroke engine.
Filling a gas-powered engine can be a bit tricky because two-stroke engines need gas to oil mixture to run (most common home tools), whereas four strokes only need gas to run.
An incorrect oil to fuel ratio can make the engine of a two-stroke tool seize up, and stop working.
Cordless weed eaters are fitted with fewer moving parts, therefore are much lighter than their gas counterparts.
Furthermore, cordless weed eaters are less noisier than gas-powered weed eaters, which is something worth considering if you plan on trimming in the wee hours of the morning.
Gas-powered weed eaters tend to be more powerful than electric models, that is models with a 4-stroke engine, which are typically used by professional landscapers.
Choosing between a gas weed eater and a cordless weed eater boils down to personal preference and convenience.
If you have a large yard to trim, buying a gas-powered weed eater makes sense because the battery of a cordless weed eater won’t last a long period of time. But if you have a small lawn, a battery-powered weed eater is an ideal choice.
Most lawn care professionals prefer using gas-powered weed eaters because they usually deal with larger areas, and it’s easier to carry around a can of gas than finding a location to plug in batteries of cordless models.
Difference Between Cheap Weed Eaters and Expensive Weed Eaters?
First things first—most cordless weed eaters aren’t expensive, even models from leading brands. In fact, cheap cordless weed eaters are some of the top quality budget-friendly models in this space.
However, there is a range of cheap weed eaters that feature poor build quality, owing to the poor quality materials used in their construction.
Batteries of cheap weed eaters also don’t last that long, so you will have to recharge frequently, which means more time is wasted.
Adding to this, cheap weed eaters come with weaker lines, so you will have to replace the line in no time. Most, if not all cheap weed eaters don’t come with a decent set of features such as lithium-ion batteries, ergonomic designs, and/or safety features.
How Much Does a Cordless Weed Trimmer Cost?
Most top-rated cordless trimmers are more expensive than gas-powered models. But on a brighter note, cordless models are less maintenance and done with any additional oil or gas costs.
A good cordless trimmer can range from $100 to $300+, but be sure that choose a model that comes with a good battery that can cover the entire size of your yard before running out of power.
Cordless Weed Eater Buying Guide
As I mentioned earlier, cordless weed eaters aren’t expensive compared to other lawn care tools.
But you still don’t want to buy a model that showcases poor craftsmanship and isn’t safe to use. That said, here are a few factors to consider when shopping for the best cordless weed eater.
Types of Batteries
Cordless weed eaters are available in two types of rechargeable batteries—Ni-Cad batteries and Lithium-ion batteries.
Regardless of which type of battery you choose, it’s a good idea to pack an extra battery when working on larger projects.
Lithium-ion batteries are becoming increasingly common with weed eaters and other power tools, and are designed to provide increased performance, and are 50 percent lighter than Ni-Cad batteries, which is why most weed eaters that use them are extremely lightweight.
Lithium-ion batteries don’t experience any drop in performance or power and deliver consistent current through their entire cycle of use.
Another noteworthy feature of Lithium-ion batteries is they can be recharged three times more than Ni-Cad batteries before the end of service life.
Ni-Cad batteries are an older form of battery technology and are relatively heavy. All the best cordless weed eaters mentioned on this list come with Lithium-ion batteries, which can range between 18 volts to 82 volts.
Types of Cordless Weed Trimmer Shafts
Just like there are two different types of batteries available, weed eaters can come with either a straight shaft or curved shaft.
Curved shafts are far less common in the cordless weed trimmer category, and none od the models on this list have them.
Straight shaft cordless string trimmers are easy to use under fences and tight spaces and corners. Many of these models come with a telescopic rod, which allows users to adjust the shaft to their desired height.
Ergonomic Design and Weight
The best cordless weed trimmers feature an ergonomic design and arrive complete with an ergonomically designed handle. This allows you to use the tool without putting strain on your hands.
Given that you may be using a cordless weed trimmer for extended periods, buy a tool that’s lightweight, and one that’s easy to control.
Cordless Weed Trimmer Line or Blade
This is the component that makes the cuts, so you already know how important it is to buy the right one.
Weed eaters can come with either a line or a blade, where the latter is basically a string that has a gauge between .060″ and .095″ in diameter. Weed eaters with blades are a great choice for tough weeds and other unwanted items growing in your garden.
How to Use a Weed Eater?
One of the things to think about when operating your cordless weed eater is which way the debris will be going. There are two types of rotation—clockwise and counterclockwise.
If you’re a right-handed weed whacker, and your debris ejects from the left side and cuts best from the right, use the trimmer in a way that the line spins counterclockwise Contrarily, if you’re a right-handed weed whacker, and if debris ejects from the right side and cuts best from the left, use the tool in a clockwise direction.
Using Your Cordless Weed Eater to Trim, Edge, Taper Scythe
A cordless weed eater is a multifaceted tool, in that it can be used for multiple jobs such as trimming, edging, tapering, and scything.
Trimming – when using a cordless weed trimmer for trimming grass, hold the tool so the strings hit the grass at a slight 5-degree to 10-degree angle, while moving side to side.
Edging – this is a great way to make the borders of your lawn look cleaner. For edging, hold the cordless weed eater vertically to the ground at a 90-degree angle, and move along the edges to cut the top layers of grass.
Tapering – this method entails cutting the edges of the grass at a 45-degree angle to blend the edges with the mowed height of the grass.
Scything – if you have tall grass or grass against an obstruction, move your cordless weed eater in a “U” motion to even out the cut.
How to Maintain Your Cordless Weed Eater?
Regardless of the model of cordless string trimmer you have, the line will have to be replaced at some point.
The way to replace the line depends on the respective model like whether the trimmer is a single-line model or dual-line model. The best way to replace your line is by following the manufacturer’s instructions.
Before storing your weed trimmer, allow the tool to cool, and remove any debris or clippings from the head.
Weed trimmers are available across an array of different brands and models, but the 10 best cordless trimmers mentioned on this list won’t disappoint you in the yard.
