What should I look for in a cordless string trimmer?
In order to choose the best cordless weed eater, you should understand some string trimmer terminology and available features, so you can make a comparison between available models as a pro!
And then, depending on the volume of your trimming work, and on things that are most important to you personally (for example, you would rather choose comfort vs price, or vice versa ☺️), decide which cordless weed eater to purchase.
String trimmer terms you should get to know:
Trim width: this is a diameter of the swath of the strings as they spin. It ranges from 12 to 15 inches in different models, some weed whackers even offer adjustable trim widths. The larger trim width will increase your productivity and will be useful for large trimming jobs.
Battery: the higher the amp hour rating on the battery, the longer the battery charge will last.
Motor. Weed eaters can come with brushed and brushless motors. A brushless motor delivers Increased run time and power. According to Popular Mechanics magazine, a tool with a brushless motor adjusts according to the task, it pulls only the charge it needs from the battery. That is why brushless motors are called “smart”.
String management Some weed eaters have pre-wound spools of string readily available which makes it easy to replace, but in some string trimmers you must replace string by yourself. And because the string is stiff, it might be hard to manage and wind neatly without crossed lines. If you value your time and don’t want to get frustrated, get a trimmer with pre-wound replacement spools or with an advanced string management system.
Variable speed: if offered, this option allows the user to go at a lower speed where more precise cuts are needed, or at a higher speed for a tougher job. Lower speed also pulls less charge from the battery.
Tool weight: if a string trimmer is heavy you will get tired quickly by using it. Consider the amount of strength you have, and pay attention to the weight and the length of the tool. Also, if a weed whacker is hard to control you cannot cut precisely and might damage plants or bushes around which you are trimming grass or weeds.
Ergonomics: check if the shaft is telescopic, so you can adjust and comfortably use the tool. Some models come with an adjustable handle on the shaft, so it can be fitted to right or left hand operation.
Safety: most weed whackers have a “kill switch” that turns it off, but some don’t. Kill switch is a throttle or trigger that you constantly hold while you’re using the device. When you release this trigger, the tool automatically shuts off. If your weed whacker doesn’t have this type of throttle, find out how to safely turn off the device before you start using it.
Shaft: can be straight or curved. The straight shaft allows you to work in tight spaces. It is a preferable option if you have a small yard to take care of.
Multi functioning: some weed whackers are stand alone tools and some are advertised as trimmer/edger. If a tool offers an edger option, check if the edger has wheels to guide the tool along an edge.
Pivoting cutting head: allows you to use the tool as an edger, or adjust it to trim grass and weeds on slopes.
Also, consider if the tool that you want to get accepts other attachments you might want to obtain in the future and if the battery is interchangeable with other tools of the chosen manufacturer.
How Was Weed Eater Invented?
The first weed eater was invented by George Ballas in 1971 out of necessity, when one of his employees was bitten by a poisonous snake while trimming the lawn with grass shears.
George Ballas got inspiration for the tool from watching his car getting cleaned by spinning bristles in an automated car wash.
The first two Weed Eater models were called the “Weedie” and the “Clippie.”
Weed Eater was sold to Emerson Electric company, which later merged with Poulan, and finally was acquired by Husqvarna in 1986.

How to use a string trimmer the right way
if you’re moving along a fence or walkway, keep the right side of your body closer to the work. In this position the head of the weed eater will throw the grass to the left.
If you go the opposite way, the trimmer will throw grass and weeds into the cut path. The cut grass will pile up along your cut line and can choke your trimmer.

Electric corded string trimmers vs battery operated weed eaters vs gas weed whackers
As you might know, weed trimmers can be electric (corded, or cordless: battery operated), or gas powered.
Electric trimmers are usually lighter, which makes them easier to maneuver and carry around. They also do not produce emissions and are less loud in comparison with gas trimmers.
The drawback of electric corded trimmer is that you need to have a heavy duty extension cord to use it, and be careful not to cut it while using the machine.
The cons of battery powered weed eaters are that your trimming work is limited by the time of your battery charge. The way to go around it is to buy an extra battery and have it charged and ready to go. Extra battery and charger are readily available from most manufacturers.
Also, the manufacturers of lawn and garden tools and equipment make the battery swappable between devices in some lines of their products.
For example, Black and Decker 20V Max battery can power a range of lawn and garden machines (tiller, string trimmer, hedge trimmer, sweeper), as well as vacuums and power tools. It will work with any 20 V MAX Black&Decker products you own.

Electric lawn and weed trimmers are perfect for maintaining smaller yards. they are easpecially great if you are female, then a battery operated trimmer is for sure the way to go.
Now, about gas weed whackers.
The advantages of gas trimmers is that they have a bit more torque, so you can use them on heavier foliage and woodier stems. Also, some gas trimmer models have detachable heads for trimming grass and weeds and for cutting shrubs and bushes.
The disadvantages of gas trimmers are that they are loud, heavy and stinky. They produce dangerous fumes.
Gas trimmers are more useful if you have a big yard and strong muscles. 🙂
Why are "weed whacker" and "string trimmer" called this way?
The tool is called weed eater because Weed Eater was the name of the company that made the first lawn and weed trimmer. And though now a lot of companies are making this tool, the name stuck.
The tool uses a thin nylon string that cuts long grass or weeds, that is why it’s a string trimmer.
The point is: weed eater, weed whacker, string trimmer are all the same tool.
