Under $50, string trimmers are mostly newer brands and third-party DeWalt-compatible accessories, but several genuinely include two batteries or automatic feed technology. We compared four current models that stay genuinely under this ceiling.

3 Criteria to Look For Before Buying a String Trimmers Under $50 (2026)

Key buying criteria so you get the right fit the first time.

Tool Only vs. Complete Kit

One of these four models is sold tool only, assuming you already own a compatible DeWalt 20V battery, while the other three include batteries as part of the package.

Factor in whether you'd need to buy a separate battery before assuming the tool-only listing is the better deal within this budget.

How Much Room Under the Ceiling

These four models all genuinely stay under this budget's ceiling, but with meaningfully different amounts of room to spare between the lowest and highest priced picks.

The lowest-priced pick leaves the most room, while the two-battery and automatic-feed models sit right at the ceiling.

Battery Count and Capacity

Two of these four models specifically include two batteries rather than one, extending real usable runtime without stopping to recharge mid-session.

Check included battery count and capacity specifically, since this varies even among similarly priced options at this budget.

20V Electric Cordless String Trimmer, 2 x 2.0Ah Battery Powered with Charger
Two Batteries IncludedLightweight Build20V System

About this pick

This lightweight model includes two batteries as a genuinely complete kit, sitting right at the very top of this budget with essentially no room to spare above it.

For a buyer wanting extended runtime and a lightweight build without spending beyond this ceiling, the two included batteries let you keep trimming through a longer yard without stopping partway to recharge, making this the strongest overall pick here despite its newer-brand status.

The lightweight construction specifically helps with the angled grip most string trimmers require, reducing wrist and shoulder fatigue over a session longer than a few minutes, though checking recent buyer reviews for build quality is worth the extra step given the newer brand.

Best for: buyers wanting extended runtime at the top of this budget

Automatic Line Feed2-in-1 Design12-Inch Swath

About this pick

This model doubles as a trimmer and edger with automatic line feed, sitting right at the very top edge of this budget alongside the lightweight pick above.

For a buyer wanting 2-in-1 functionality without manual line management, the automatic feed mechanism advances the cutting line on its own rather than requiring you to bump the head against the ground repeatedly, a genuine convenience during a longer trimming session even at this accessible price.

The edger mode reconfigures the same head into a vertical cutting position for clean lines along walkways or driveways, avoiding the need for a completely separate tool at this budget.
