How we research
This guide is built on structured research rather than in-depth research of every product. We compare each model against the manufacturer's published specifications and manual, cross-check verified owner feedback for real-world reliability and performance, and weigh each pick against the strongest alternatives in its category. Where a recommendation reflects first-hand experience with a tool, we say so. See our full research method.
What to look for
Battery System
Consider the battery platform you already own. Sticking with the same brand saves money on extra batteries and chargers. If starting fresh, look for a system with multiple tools available.
Cutting Swath and Power
A wider cutting swath (14-16 inches) covers more ground quickly but requires more power. For light trimming, 12-13 inches is sufficient. Brushless motors offer better efficiency and torque.
Weight and Ergonomics
Heavier trimmers can be tiring. Look for adjustable handles, telescoping shafts, and balanced designs. Consider where the battery is mounted (rear or front) as it affects balance.
Line Feed Mechanism
Bump feed heads are common and reliable, but automatic feed heads save time. Some models offer dual-line heads for faster cutting. Check how easy it is to reload the line.
Our verdict
For most homeowners, the EGO Power+ ST1623T offers the best combination of power, runtime, and comfort, making it our top pick for 2026.
FAQs
Runtime varies by model and battery capacity. Most trimmers run 30-60 minutes under normal use. Larger batteries (5.0 Ah or more) can last over an hour. Actual runtime depends on grass thickness and speed setting.
Yes, many trimmers can be rotated to an edging position. Some have a dedicated edging function or an attachment. Check if the trimmer head pivots or if an edger attachment is available.
Modern battery trimmers, especially 40V and 60V models with brushless motors, can match or exceed gas trimmers in power for most residential tasks. However, for extremely thick brush, gas may still have an edge.
