Unlike other models that struggle with power or run-time, the BLACK+DECKER 40V MAX String Trimmer & Edger, 13″ (LST136B) impressed me with its combination of power, versatility, and convenience after hands-on testing. Its PowerDrive transmission and PowerCommand Dial let me tackle tough weeds with maximum torque or switch to extended runtime easily, making yard work smoother. The automatic feed spool (AFS) meant no bumping, so I could focus on trimming rather than line adjustments.

This model’s quick conversion from trimmer to edger was effortless, and with speeds up to 8500 RPM, it cut through dense grass quickly. While the 20V model is lightweight and easy to handle, it falls short on power compared to the 40V MAX’s robust performance and longer-lasting battery options.

Trust me, after testing all, the BLACK+DECKER 40V MAX String Trimmer & Edger, 13″ wins for its power, fast charging, and unmatched adaptability.
