Features To Consider When Buying Best Cordless String Trimmers

Power Source

In cordless string trimmers, the source of electricity determines the tool’s power output. Keep in mind that gas-powered and battery-powered string trimmers are not interchangeable while looking for the best cordless string trimmer. CCMs are the standard unit of measurement for gas-powered string trimmers’ engines (cc). This affects the amount of power generated. The voltage of the battery affects the power output of trimmers driven by batteries.

A larger engine or a higher voltage battery generates more power (volts). Because of this, the string can be used to cut through thicker grass and weeds without getting caught up. As a result, the best battery-powered string trimmers use the most powerful batteries. Gas models of the highest quality are similarly referred to.


As a result, homeowners with limited upper body strength, such as the elderly, may find it difficult to utilize grass trimmers. Consider the weight when evaluating the best cordless string trimmers available today. There’s no point in picking an overly cumbersome tool if you don’t intend on using it frequently. In order to have a better idea of the weight, you can read past customer reviews and see what they had to say. Some cordless weed eaters (usually sold separately) come with a shoulder harness that reduces the pressure on your arms and back.

The thickness of the Trim

Cordless trimmers may cut a path as broad as their “path width,” which is another name for “swath width.” Ten to 18 inches is the typical range for today’s lawnmowers. There is a direct correlation between the weight of a weed whacker and the amount of power it has. Cordless models with large cutting heads and swaths help you get the work done faster by allowing you to cover more ground in less time. Compared to gas-powered machines, electric ones offer wider cutting swaths. Cutting heads with a smaller diameter can be more maneuverable when operating in cramped quarters.

Trim Width

Trimmer string line diameter is a measure of the string’s holding capacity in terms of thickness. Thicker string has more tensile strength and can be used to cut through weeds and grass that are much thicker and higher. The best cordless weed eaters use thicker string. Lines that measure between 0.065 and 0.08 inches are excellent for residential use. If you’re going to be doing a lot of heavy lifting, a 0.095-inch or even thicker thickness is a good idea.

Battery Type

Power is everything when it comes to operating a string trimmer. Lithium-ion batteries power the most majority of battery-powered string trimmers, however nickel-cadmium (NiCad) batteries are also available. The cost of lithium-ion batteries is more than that of NiCad batteries, but they are more powerful. In terms of size and capacity, lithium-ion batteries are superior. NiCad batteries have a “memory effect,” which means that if they are used or recharged before they are fully charged, the battery will remember the charge levels and not be able to store a longer charge in the future. Preferably, you should use a fully charged NiCad battery-powered string trimmer first, and then let it run out of juice completely before recharging the battery.
Lithium-ion string trimmers, on the other hand, are more popular with consumers.


Another important consideration is the battery’s capacity. This is measured in volts. 18 to 60 volts is the normal voltage range for rechargeable batteries. Devices with greater voltages are more powerful and expensive. Batteries and chargers for string trimmers that demand greater voltage are more likely to be sold without them. Therefore, the user will have to pay for each one separately. A battery or two is commonly supplied with the purchase of most cordless trimmers that can be powered by lower voltage batteries.


It is quieter to use battery-powered string trimmers than gas-powered string trimmers. If you stand 25 feet away and listen to the noise from a gas trimmer, you’ll hear the same decibel level as a passing motorcycle. The sound level produced by a cordless string trimmer, on the other hand, is comparable to that of a stereo system in a living room.

Battery Life

The amount of time a cordless trimmer may be used before needing to be recharged is also crucial. Battery-powered equipment that can operate for an hour or more without needing to be connected to a power source is the ideal. Consider the work at hand and the battery life of the device you’re considering before making a final decision.

One String Or Two

Cutting strings can be used by weed eaters in quantities as small as one or two. The best cordless weed eater with many strings is ideal for heavy-duty work, as it makes it easier and faster to cut through stubborn grasses and weeds.

Frequently asked Question

Why Is A Brushless String Trimmer Better?

A brushless tool’s advantages include a longer lifespan, a more efficient operation, and a longer battery life. You’ll never have to buy new brushes again. The performance of a brushless motor vs a brush motor in the same tool will never be equaled by a brush motor.

Are Brushless Trimmers Better?

Brushless motors are more efficient than brushed motors. Users may benefit from lower maintenance, increased efficiency, and lower heat and noise levels. Brushless motors, which are synchronous units, use permanent magnets. Brushless motor-driven power tools are now considered high-end goods.

What Is Better Curved Or Straight Shaft Trimmer?

It is necessary for the drive cable to be flexible in order to accommodate the curve of the shaft. In consequence of this, curved shaft trimmers are not as sturdy as straight shaft trimmers and are not as well suited for extended periods of usage. This is the case despite the fact that braided cables provide some support. In addition, the cable drivers on bent string trimmers always rotate in the clockwise direction.

What Is Better Than A String Trimmer?

A brush cutter is more powerful than a string trimmer, and while it can clear grasses and weeds, as well as edge a sidewalk with the right accessories, it is built for much thicker brush and undergrowth, and it can even chop down small trees. Brush cutters come with a number of accessories to suit a variety of applications.

What Is The Easiest Grass Trimmer To Use?

Our top pick is the Ryobi 40-Volt Lithium-Ion Brushless Electric Cordless String Trimmer because of its exceptional performance, ease of use, and compatibility with other Ryobi equipment. Another good option is the Worx 12 Inch 20 Volt Grass Trimmer/Edger.


It may seem confusing at first but you don’t have to stress about all the different models available. Just make a list of your desired trimmer’s functions, battery life and other accessories, then find the best match from our top picks above.
