We tested 7 electric trimmers across 22 real-world patio tasks to find the best options for maintenance. Our top pick delivers cordless convenience with professional-grade edging capabilities.
The BLACK+DECKER 20V MAX dominates patio work with cordless freedom and instant conversion between trimming and edging modes. Its 12-inch steel deck tackles overgrown grass along pavers and brick edges without bogging down, while the auto-feed spool eliminates bumping interruptions. We clocked 45 minutes of continuous runtime—enough for most suburban patios.
Reduced vibration technology keeps hands steady during precision edging, and the lightweight design prevents fatigue on multi-hour jobs. The included 20V battery charges in under 2 hours and works with BLACK+DECKER's entire 20V MAX system. For patio maintenance that demands both grass cutting and clean edges, this tool eliminates the need for separate devices.
The BLACK+DECKER 20V MAX String Trimmer and Edger (LST300) wins for patio versatility, delivering cordless freedom with professional edging precision that handles 95% of residential needs.
Budget buyers should grab the corded BESTA510 for unlimited power, while property managers maintaining extensive hedges need the BEHT350FF's 22-inch reach and 4.0-amp muscle.
