Greenworks 80V 16ft Carbon Fiber Brushless String Trimmer - Quiet

In this review of the Greenworks 80V 16' Carbon Fiber Brushless String Trimmer, the conclusion is simple: buy it if you want near-gas power without the noise, weight, or maintenance of gasoline tools. The single biggest reason to choose this trimmer is the combination of an 80V brushless motor delivering about 6,000 RPM (equivalent to a 30cc gas trimmer) and a lightweight 11.2lb carbon fiber frame that makes long edging and fence-line work far less tiring. It starts instantly, needs no gas or tune-ups, and is quiet enough for neighborhood use.

Key Features

• 80V Brushless Motor: Provides roughly 6,000 RPM and gas-equivalent cutting power to handle 1' thick blackberry vines and dense underbrush.
• .095 Dual-Line Bump Feed: Supplies reliable line delivery to maintain up to 2 miles of fence line or approximately 1.5 acres per charge on routine work.
• Carbon Fiber Frame: Cuts overall weight to 11.2lbs with battery, reducing arm fatigue by lab-validated 40% over extended use while remaining strong.
• Variable Speed Trigger: Lets the user switch between a low speed for delicate edging and a high speed for chewing through heavy ditch weeds.
• Battery Compatibility and Coverage: The included 2.0Ah battery powers 75+ Greenworks tools and comes with a 4-year full coverage warranty for tool and battery.
• Quiet, Maintenance-Free Operation: Runs at 72dB, starts instantly, and eliminates gas, oil, and tune-up costs.

Who It's For

The trimmer is ideal for homeowners with long fence lines, ditch banks, or HOA yards who want near-gas performance without the smell, maintenance, and weight of a gas trimmer. Its light carbon fiber frame and ergonomic handle suit users who do extended edging or who want to keep noise down in a neighborhood.

It is less well suited for users who need continuous commercial-day runtimes without swapping batteries, or those who already own a large 80V battery bank and prefer heavier professional-grade metal frames. Buyers who need the longest possible runtime per session should consider higher-capacity batteries sold separately.
