EGO Power+ ST1502 56V - Best Battery Life
EGO’s Power+ ST1502 packs a 56 V battery that offers up to 2 hours of runtime, a standout for larger lawns. Its 15‑inch cutting swath and auto‑feed line system keep the work moving without manual adjustments. At 10.8 lb, it’s lighter than many 60 V rivals, making it comfortable for overhead trimming. The detachable battery is compatible with other EGO tools, adding value for users already in the ecosystem.
Greenworks 21142 40V - Best Budget
Greenworks delivers solid performance at a friendly price point. The 40 V battery provides roughly 90 minutes of run time, enough for average suburban yards. Its 13‑inch cutting width and automatic line feed simplify operation, while the lightweight 9 lb frame makes it ideal for beginners. Despite the lower price, the brushless motor ensures consistent power and longer motor life.
Ryobi RY40120 18V ONE+ - Best Lightweight
For small gardens and quick touch‑ups, the Ryobi RY40120 uses the popular 18 V ONE+ battery platform. Weighing just 6.5 lb, it’s the lightest in this list, reducing arm fatigue. The 12‑inch cutting width is sufficient for tight spaces, and the detachable battery swaps seamlessly with other Ryobi ONE+ tools. Runtime is shorter-about 45 minutes-but the low price and convenience make it a great entry‑level choice.
BLACK+DECKER LST1330 40V - Best Versatile
BLACK+DECKER’s LST1330 offers a balanced mix of power and flexibility. The 40 V battery delivers up to 1 hour of runtime, and the 13‑inch cutting diameter handles medium‑thick grass with ease. Its pivoting head and adjustable telescoping shaft let you reach under bushes and over fences without reshaping your stance. At 11 lb, it’s sturdy yet portable enough for most residential tasks.
How to choose
What to consider
When selecting a cordless string trimmer, start with battery voltage. Higher voltage (50‑60 V) generally means more torque and longer runtime, which is crucial for larger or densely vegetated yards. For smaller spaces or occasional use, a 18‑40 V model can be more than sufficient and saves on upfront cost.
What to consider
Next, consider cutting width and line feed system. A 15‑inch diameter clears ground faster, but a wider head adds weight. Automatic line feed eliminates the need to manually pull the line, improving convenience. Finally, evaluate ergonomics: a padded grip, adjustable shaft, and low‑vibration motor will reduce fatigue during long sessions. Matching these criteria to your yard size, terrain, and budget will ensure you pick a trimmer that delivers reliable performance year after year.
Common questions
Yes, most modern cordless trimmers feature low‑vibration handles and adjustable shafts that give you better control on slopes. Choose a model with a lightweight battery pack to reduce fatigue.
A 40 V lithium‑ion system, like the EGO Power+ ST1502, usually offers the best mix of cutting power and several hours of runtime for average residential yards.
