FAQs

1. What is the difference between a string trimmer and a weed wacker?

A string trimmer and a weed wacker are essentially the same tool, both designed to trim grass and weeds in hard-to-reach areas. "Weed wacker" is just a colloquial term for string trimmers.

2. How long do the batteries last on cordless string trimmers?

Battery life typically ranges from 20 to 60 minutes of runtime, depending on the model and the battery capacity (e.g., 2.0Ah or 4.0Ah).

3. Can a cordless trimmer handle thick weeds?

Cordless trimmers can handle light to moderate weeds, but thicker, more stubborn weeds may require a gas-powered trimmer for better performance.

4. Are cordless string trimmers better than gas-powered ones?

Cordless string trimmers are more eco-friendly, quieter, and easier to maintain than gas-powered models, though they may have less power for heavy-duty tasks.
