BLACK+DECKER 40V MAX 13 in 2in1 Cordless String Trimmer/Edger

In this review of the BLACK+DECKER 40V MAX 13 in 2in1 Cordless String Trimmer/Edger, the bottom line is simple: it is a versatile, easy-to-use tool for routine yard maintenance that pairs enough power with long battery life to handle most suburban trimming and edging tasks. The kit format, which includes a 40V MAX lithium ion battery and fast charger, makes it a convenient all-in-one option for homeowners who want a cordless unit that converts quickly between a trimmer and an edger without sacrificing cutting performance.

Key Features

• 2in1 design: Easily converts from string trimmer to edger so a single tool handles both lawn edges and general trimming for fewer tools to store.
• POWERDRIVE Transmission: Delivers increased torque for better cutting action through thicker grass and common yard weeds, reducing stalling under load.
• AFS Automatic Feed Spool: Continuously feeds line without bumping, which keeps the workflow uninterrupted and reduces frustration while trimming.
• POWERCOMMAND Dial: Lets the user toggle between max power and max runtime so you can prioritize cutting performance or longer battery life depending on the task.
• Adjustable comfort features: The soft-grip handle and adjustable height offer better control and reduced fatigue for longer trimming sessions.
• Included battery and charger: The 40V MAX 2.0Ah battery and fast charger are part of the kit, so the tool is ready to use out of the box and the battery works with other tools in the same system.

Who It's For

This tool is aimed at homeowners with small to medium yards who want a cordless, lightweight option that handles both edging and trimming without switching machines. It suits users who value battery convenience, easy line feeding, and a balance of power and runtime for routine maintenance.

Those who should look elsewhere include users with very large properties who need extended runtime beyond what a single 2.0Ah battery offers, and professionals who require heavy-duty commercial equipment built for continuous, all-day use.

Pros & Cons

Cons

• Battery capacity in the included 2.0Ah pack may be limiting for very large yards without a spare battery.
• Durability feedback is mixed from some users, so heavy commercial use may reveal limits over time.
