Best Cordless String Trimmer 2021 Buyers’ Guide 

Before you buy a battery-powered string trimmer, there are various features that you need to consider when making the best purchase decision and to help suit the requirements of your lawn. You also need to consider the advantages you will derive from the unit and whether it is worth the investment. This guide helps provide you with the desirable features you must consider before buying the best cordless trimmer models and integrates the primary merits of why you prefer cordless trimmers to the corded unit.

Advantages of Cordless String Trimmers 

The advancements in technology have undoubtedly transformed a range of activities worldwide, ranging from production, communication, household works, and gardening. Today, instead of engaging the tangled cords connecting machines to the power sources, there are cord-free, lightweight, and efficient battery-operated models such as the cordless string trimmers that provides individuals with easy reach to their garden and supports long working hours without getting fatigued.

Below are the primary advantages of the cordless string trimmers;

Quiet Operation

Nothing bits working in a pleasant environment, free from noise. The best cordless string trimmer units are much quieter than the corded types, and this means you will not disrupt the peace of your neighbors as you maintain your lawn. You might not even need ear protection when operating a cordless hedge trimmer.

Thus, when shopping, look for a unit with a sound pressure of below 75dB (A). Such units are efficient and are quieter than the electric and petrol-operated string trimmers. A good example of such a unit is Flymo EasiCut Cordless 20 V Li Hedge Trimmer with only 71.3dB (A) sound pressure.

Replacement Batteries 

Most of the cordless trimmer units have batteries that can be replaced with those from other tools. For instance, if you have an edger, you can swap the batteries as long as they have the same voltage. Also, you can purchase an extra pair of batteries for use when the other charge for continuous operation, enhancing the run time. 

Lightweight and Compact Design 

The cordless string trimmers are lightweight, making them portable, increasing the efficiency and convenience when executing the garden work. You can work with these models for long hours without getting fatigued.

The units are operated from rechargeable batteries, and this eliminates the need for long cords for the electric types or extra petrol cans for the petrol-operated types. This reduces their weight, facilitating reaching up and around tall or large hedges.

The compact design makes it easy to transport the tool and facilitates working even in the smallest spaces

Factors to Consider when Choosing the best Cordless String trimmer

Weight

Weight is a useful determinant when buying a string trimmer, especially considering the size and the terrain of your lawn. Most models are lightweight, and this makes them more comfortable and convenient to work with. Best cordless string trimmers should not exceed 10lbs as this will be too heavy for you when you maneuver around your lawn. The best weight should be between 4.5 lbs and 8lbs. It should not also be tool light since it will not penetrate through thick weed infiltration.

Battery 

Best cordless string trimmers use the lithium-ion battery in their operation because they are lightweight and have a longer life with a single charge. However, when you intend to use your model commercially, or you have more than one lawn to trim, you can keep a backup battery for use while the other charge to prevent work breakdown. Also, you can consider the models whose batteries are compatible with the tools you have in your tool collection. This helps you not to spend on extra battery.

Power

It is with no doubt that the gas-powered models have higher power than the battery-powered trimmers. This is primarily a concern if you have used the former before and now you want to change the course.

However, the advancements in technology, the cordless string eaters have become more powerful, especially with the integration of the various features such as brush-less motors that have ensured there are no energy losses due to friction.

Trimmer Design 

The best cordless string trimmer is one with an ergonomic design. When choosing a weed eater, you should go for a model with ergonomic design as they are characterized by even distribution of weight throughout the trimmer.

The unequal distribution of weight in a string model implies there can be more weight at the top of the tool than the lower part, which reduces the comfort of using the device. The unequal distribution of the weight in the model also influences the control of the machine. It would help if you chose a tool that is comfortable and convenient to handle.

Moreover, you should consider the nature of the telescopic shaft when buying the weed eater. We recommend the models with straight shaft since they quickly transfer power from the motor of the tool to the lines used for cutting. The straight shaft also ensures a balanced system when you use the machine once you have positioned it to your height or level.

Trimming Area

The size and nature of the area you need to trim are vital when choosing the best cordless string trimmer. For instance, if you need to cut a large area, you should go for a model with longer battery life and more power to give you a longer run time.

On the other hand, if you are working on a small lawn, you may go for cheaper models to help you execute your work within a short time. The shape of the yard is also essential, whether sloppy or straight. You must consider buying a model with an angled head. Such models can help you to quickly and conveniently cut and edge sloped terrain, and even get in tough-to-reach places since its head can easily tilt to 90 degrees.
