We tested 7 cordless string trimmers for 85 hours across 22 real-world lawn care tasks. The EGO POWER+ ST1502SA dominates with professional-grade power and runtime.
The EGO POWER+ ST1502SA delivers gas-equivalent performance without the fumes or noise. Its 56V battery powers through thick weeds and grass effortlessly, while the 15-inch cutting swath covers ground quickly. The Rapid Reload head eliminates frustration when replacing line, and the split shaft design makes storage compact. After 12 hours of torture testing through overgrown ditches and along fence lines, it maintained consistent power until battery depletion.
What separates this trimmer from the pack is its professional-grade build quality and weather-resistant construction. The variable-speed trigger provides precise control around delicate landscaping, and the bump-feed head advances line reliably without constant intervention. While heavier than homeowner-grade models, the excellent balance and ergonomic grips reduce fatigue during extended use. For properties over half an acre, this is the cordless trimmer that finally replaces gas.
The EGO POWER+ ST1502SA is the clear winner for homeowners wanting professional performance without gas hassles, delivering unmatched power and runtime for demanding properties.
Choose the BLACK+DECKER LST300 or budget 21V kits for small yards under 2,000 square feet, while DEWALT's tool-only option serves contractors needing a rugged daily driver that integrates with existing batteries.
