Some outline of a cordless string trimmer
If you want your backyard to look neat and manicured, a regular trimming of lawn grass is required. Thus, string trimmers also referred to as weed eaters have been highly demanded for years, making gardening routine easy and pleasant for an average householder. If a territory of your garden is more long than wide, the electric corded trimmers are less convenient due to a limited length of a power cable. Even the long extension cords sometimes are not enough to reach some odd corners. The gas-powered tools are very noisy in operation followed by polluting emissions. Thus, a lightweight, portable and user-friendly cordless trimmer is here to help you.
I have reviewed various battery-powered models which are suitable for lawn maintaining and weed cutting at hard-to-reach areas. Besides, I have prepared my own list of the best models basing on the benchmarking of their features and reviews from the professionals and regular customers.
What features should be considered when looking for a cordless string trimmer? | Buyer's Guide
Power output. It is one of the most important characteristics, you should pay attention to. This is the main indicator which determines the force of a motor. In majority of cases this parameter is measured in Watts; however it can be represented in horsepower, as well. The power output of cordless trimmers is considerably lower as this type of electric trimmers is used for light-duty jobs and less frequently. Less powerful motors are less expensive, thus reducing the overall cost of the tool. That is why, when selecting a tool for an occasional use, you shouldn’t strive for the extremely powerful models, like gas-powered options, if there’s no reasonable need for this.
Cutter. You should check the possibility of using a particular type of cutting accessory. If you are going to deal with a thin-stalked grass, then you’d better choose a tool with a nylon line or plastic blades. But if you have to trim small bushes, or dry and rough grass, then it would be reasonable to use steel cutters and cutting blades.
RPMs. Another indicator of tool's performance is determined by rotations of a cutter per minute. Low-power string trimmers feature speed ranges which are less than 7000 RPM. The professional-grade units are capable of obtaining up to 12000 RPM. However, the speed of 6000 RPM will be enough for maintaining a small garden or a backyard.
Shaft design. This part of a weed eater transfers power from the motor or engine to the cutting lines. It is commonly thought that curved-shaft trimmers are less reliable than the straight-shaft counterparts. The latter are commonly equipped with metal cutters and blades and a design which allows cutting of underneath shrubs and bushes at the hard-to-get areas. Curved shaft trimmers use only nylon line and plastic blades. However, they are lighter in weight and easier to maneuver. Thus, the straight shaft models are considered to be a powerful and professional-grade tools for operation under higher loads. The curved-shaft options are mostly used for residential purposes.
Cutting width. It is logical to assume that the tools with higher performance are capable of trimming wider spaces in one pass. However, when cutting of smaller or narrower lawns, the cutting width won’t be a crucial feature. Thus, we can make a conclusion that the assessment of this feature will be reasonable only when selecting a trimmer for large-scale jobs. However, it is worthy to mention that the most average string trimmers available on the market are offered with the cutting width ranges from 10 to 18 inches.
Battery type. You should learn carefully about the properties of a battery as it is a highly important component for an adequate performance. There are three main types currently available on the market. Lithium-Ion batteries take the lead among other options like Ni-Mh and Ni-Cad power sources. They are distinguished with higher power output, better capacity, low memory effect and environmental-friendliness. However, they will hit your wallets as li-Ion batteries are pricier options in comparison with the less powerful counterparts which are not so demanded nowadays.
Battery voltage. The average cordless string trimmers are offered with 14.4V-40V batteries. As you may imagine, the voltage rating determines the capacity of a tool. Thus, high-voltage batteries contribute to better cutting efficiency of a string trimmer.
Battery capacity. This parameter determines a continuous runtime of a tool. In general this time is in the range of 1.3 to 4.5 Ah. In particular, a string trimmer with a 2Ah battery is capable of cutting up to 20-30 minutes without any recharge. Nowadays, the most advanced batteries are capable to withstand up to 1 hour of a continuous operation before they are fully empty.
Noise level. The cordless string trimmers have one apparent advantage of ability to work with less noise in comparison with corded and gas-powered models. The latter are especially noisy during operation due to the peculiarities of their design and the gas engine. Quiet battery-powered units can be used at any time of the day without producing unpleasant sounds which can be irritating both for a user and those around.
Weight. This feature can influence on the convenience during operation of a string trimmer and on fatigue of its operator. In general, the weight can be varied from 3 lbs up to 20 lbs. it would be reasonable to prefer lighter models for the extended operations. However, such type of work may be performed at some remote locations with no regular power outlet, thus requiring gas-powered models which are the heaviest among other types of string trimmers. Cordless models usually weigh from 5 up to 11 lbs.
What are the main advantages of cordless string trimmers?
What can make you hunting for a cordless string trimmer? What unmatched advantage does it have which distinguishes the battery-powered option from other corded or gas-powered counterparts? It goes without saying that there are a lot of such benefits. First of all, it gives a sense stability and thus confidence during operation. This fact is explained by the right positioning of a motor, plus anti-vibration arms which represent a kind of extension of a shaft which allow operating your cordless buddy with one hand.
The lightweight of this type of string trimmers also contribute to convenience and ease of its operation. This benefit allows anyone to handle cordless string trimmers easily. Even women can operate it without fatigue, as no outstanding physical abilities are required. Besides, its light weight allows carrying such unit from one area to another. More than that, there is no longer necessity in a shoulder strap.
Another important advantage of the battery-powered models is the independence from a power cable. There is no need to take care about an extension cord or a standard power outlet available; you can cut the grass at any remote location. Forget about annoying cords on your way and feel the freedom of your motions while creating the best of your garden landscape.
