How to choose the right one
-
Check voltage for power
Voltage indicates the motor’s potential power output. Higher numbers generally mean more torque for thick grass. The NovorikX 60V model offers high voltage for wide swaths, while the CRAFTSMAN 20V version provides adequate power for standard residential lawns. Match the voltage to your yard’s density. If you have tough weeds, a 40V or 60V system may clear them faster than a lower-voltage option.
-
Match cutting width to area
The cutting width determines how much grass you cut in one pass. A wider swath, like the NovorikX 17-inch or Bosch 16-inch models, covers more ground quickly. Narrower options, such as the iToolMax 6-inch or BLACK+DECKER 12-inch, offer better maneuverability in tight spaces. Choose a wider tool for large open lawns and a narrower one for edges and small yards.
-
Select the right power source
Cordless trimmers offer convenience and quiet operation, while gas models provide unlimited runtime but require more maintenance. The BILT HARD 170cc and COOCHEER 58cc are gas-powered, making them suitable for large properties where charging is difficult. For most homeowners, a cordless electric model is easier to store and operate without fumes or fuel mixing.
-
Evaluate battery capacity needs
Battery capacity, measured in Amp-hours (Ah), dictates runtime. Larger capacities like the Bosch 8.0Ah or CRAFTSMAN 5.0Ah batteries last longer during extended jobs. Smaller batteries, such as the 2.5Ah in the NovorikX or 1.5Ah in some BLACK+DECKER kits, may require swapping for large yards. Check if the battery is included or sold separately to understand the total package value.
-
Consider weight and handling
Weight affects user fatigue during prolonged use. Lighter models, like the iToolMax 4.4-pound unit or BLACK+DECKER 6.4-pound trimmer, are easier to maneuver for detailed work. Heavier units, such as the Bosch 15-pound model or gas-powered BILT HARD at 54.1 pounds, offer stability but require more strength. Select a weight you can comfortably hold for the duration of your typical yard work.
-
Look for multi-function features
Some trimmers convert into edgers or small mowers, adding versatility. The BLACK+DECKER 20V 12-inch and WORX 20V 13-inch models offer 3-in-1 functionality, allowing you to trim, edge, and mow with one device. This is useful for small lawns where space is limited. If you need dedicated edging, the EGO Power+ 56V system provides specialized modular attachments for precise border maintenance.

Which string trimmer is best for large lawns?
The Greenworks 60V 13-Inch Trimmer 3-Tool Combo is ideal for large properties. It features a 60V system with 4.0 Ah batteries, providing the sustained power needed for extensive yard care. The high voltage supports a 13-inch cutting width, allowing you to cover more ground efficiently. This kit also includes matching mower and blower tools for comprehensive maintenance.
What is the lightest cordless string trimmer available?

Does the EGO Power+ edger come with a battery?
No, the EGO Power+ 56V Multi-Head 8-Inch Edger System does not include a battery or charger. It requires you to supply your own battery if you are already in the 56V platform. This modular approach allows you to use existing power sources. The unit focuses on the 56V brushless drive and edger head for clean lawn edges.
Which trimmer offers the widest cutting width?
The NovorikX 60V 17-Inch Carbon Fiber String Trimmer offers the widest 17-inch cutting swath. This broad width allows you to clear more grass per pass, which is efficient for larger lawn areas. It includes a 2.5Ah battery and features a carbon fiber shaft for durability. The high voltage supports this wide performance for demanding yard tasks.
Are there gas-powered string trimmers in this list?
Yes, the BILT HARD 22-Inch 170cc Walk-Behind String Trimmer and the COOCHEER 58cc 5-in-1 Gas String Trimmer are gas-powered. The BILT HARD model weighs 54.1 pounds and uses a 170cc engine for heavy clearing. The COOCHEER unit weighs 29 pounds and offers multi-attachment versatility. Both are designed for tough property tasks rather than routine residential trimming.
Which model is best for small lawns?
The BLACK+DECKER 12-Inch 20V Max 3-in-1 Trimmer is best for small lawns. It combines trimming, edging, and mowing functions into a single 12-inch platform. The included pair of 4.0 Ah batteries provides reliable power for compact spaces. Its versatile design handles multiple maintenance tasks without requiring separate tools, making it practical for tight yards.
Does the Bosch trimmer have a large battery?
Yes, the Bosch 18V 16-Inch Cordless String Trimmer features a high-capacity 8.0Ah battery pack. This large battery provides extended runtime for heavy-duty clearing and anti-tangle operation. The 16-inch cutting width covers more ground, while the 8.0Ah capacity ensures you can complete larger jobs. Note that the 15-pound build adds notable weight compared to lighter models.
Which trimmer includes a brushless motor?
The CRAFTSMAN V20 Brushless 13-Inch String Trimmer includes a brushless motor. This technology supports extended runtime and efficient power delivery for standard lawn care. It features a 5.0Ah battery and an adjustable 11- to 13-inch cutting swath. The brushless drive provides controlled push-button feeding, making it a durable choice for budget-conscious users seeking reliable performance.
