Cordless String Trimmers That Keep Up With Landscaping Work
For serious landscaping work, the EGO Power+ ST1623T is the top pick because it delivers commercial grade power with a 16 inch cutting swath and a 5 year warranty. Its main limitation is the higher price, especially when you add extra batteries for all day use. It uses a 56V battery platform that also powers many other EGO tools. Owners report it cuts through thick weeds without bogging down, making it a reliable choice for daily use.
A cordless string trimmer has become a staple for landscaping professionals and homeowners with large yards. Lithium ion batteries now deliver enough power and runtime to replace gas models in many situations. The best options offer quick startup, low noise, and zero emissions while still tackling thick grass and weeds.
Choosing the right model depends on your battery platform, cutting width, and comfort features. Some trimmers use a shared battery system with other tools, which can save money if you already own compatible gear. We compared specifications, user feedback, and real world performance to find the models that earn their place in a landscaping kit.

What matters most
Frequently asked questions
What battery voltage is best for a string trimmer for landscaping?
For landscaping, look for trimmers with at least 40V, but higher voltages like 56V or 80V provide more power and longer runtime. These models can handle thick weeds and all day use. Lower voltage models (18V to 20V) are fine for light trimming around the house.
Are cordless string trimmers as powerful as gas models?
Modern high voltage cordless trimmers with brushless motors can match or exceed the power of many gas trimmers for typical landscaping tasks. They also have the advantage of instant torque and no engine maintenance. However, for very heavy commercial use, gas may still have an edge in runtime unless you have multiple batteries.
How long does a battery last on a cordless trimmer?
Battery life varies widely based on voltage, amp hours, and the load. A typical 2.5Ah battery on a 56V trimmer lasts around 30 to 45 minutes of continuous use. With a 5Ah battery, you can get an hour or more. It is wise to have a spare battery for larger jobs.
Can I use other brand batteries with a trimmer?
No, each manufacturer designs their batteries to work only with their tools. For example, EGO batteries only fit EGO tools. If you already own a battery system, consider sticking with that brand to save money on batteries.
What is the advantage of a brushless motor?
Brushless motors are more efficient, producing more power and longer runtime from the same battery. They also have fewer moving parts, so they last longer and require less maintenance. Most premium trimmers now use brushless technology.
What is the difference between bump feed and auto feed line systems?
Bump feed requires you to tap the head on the ground to release more line. Auto feed systems automatically advance line as needed. Bump feed is more common and reliable, while auto feed can be convenient but may jam occasionally.
Can I use a cordless trimmer for edging?
Yes, many cordless trimmers can be rotated 90 degrees to edge along sidewalks and driveways. Some models have a dedicated edging attachment, like the Milwaukee Quik-Lok, which allows you to convert it into an edger.
How do I choose the right line size?
Check your trimmer’s manual for the recommended line diameter. Thicker lines (0.080 inch or more) are better for heavy weeds. Thinner lines (0.065 inch) are lighter and suitable for grass. Use the correct size to avoid damaging the motor.
Are these trimmers weather resistant?
Most are designed to handle outdoor conditions, but they are not fully waterproof. Avoid using in heavy rain or submerging in water. The battery should be kept dry and stored indoors when not in use.
Do I need a harness for extended use?
A harness helps distribute the weight of the trimmer, reducing fatigue during long sessions. Some higher end models include a harness, but for others you can purchase an aftermarket one. If you are doing professional landscaping, a harness is recommended.
Final word
For most landscaping professionals, the EGO Power+ ST1623T is the clear winner because it combines the power of a gas trimmer with the convenience of battery operation. If you need to expand your tool system with attachments, the Milwaukee M18 FUEL is a strong alternative. Homeowners with smaller yards can save money with the Ryobi 18V ONE+. Buyers already committed to another battery platform should choose the model that fits their system, but for the best overall performance and value, the EGO is the one to get.
