Best String Trimmers 2026: Battery Picks for Tight Spots
We compared cutting swath, voltage, line-feed type, and kit vs. bare-tool pricing on 5 current battery string trimmers, including two honest substitutions after two original picks turned out to be Amazon dead ends.
Quick answer
The EGO Power+ ST1623T is the strongest all-rounder here because its LINE IQ system auto-feeds line without a single bump on the ground, and it's genuinely sold and warrantied through Amazon. The DEWALT DCST972B is the pick for anyone building a 60V FLEXVOLT attachment ecosystem, but note it's now a bare tool only, since DEWALT discontinued the battery-and-charger kit. Two of the original five candidates didn't survive verification: Milwaukee's M18 FUEL trimmer and the STIHL FSA 80 R are not sold through any Amazon-authorized channel, so we swapped in the Makita XRU15PT (36V LXT) and the Greenworks Pro ST80L210 (80V) as real, in-stock, comparably positioned alternatives, and we say so plainly in each of those write-ups.

How We Compared These 5 String Trimmers for Cleaner Lawn Edges and Tight Spaces
This is desk research, not a hands-on test: nobody on this team has run these five trimmers through a season of edging. We instead cross-checked each candidate against its manufacturer's own spec page, its current Amazon.com listing (title, ASIN, and buy-box status), and independent retailer or reviewer pages, and we prioritized whatever the primary source stated for cutting swath, voltage, shaft type, and line-feed mechanism. When manufacturer bullet points and third-party spec sheets disagreed on a number like weight, we listed both figures rather than picking one arbitrarily. Two of the five starting candidates, Milwaukee's M18 FUEL trimmer and the STIHL FSA 80 R, could not clear our bar for a genuine Amazon listing: Milwaukee's tools on Amazon come exclusively from unauthorized third-party resellers per Milwaukee's own dealer policy, and STIHL's cordless and gas trimmers simply aren't listed on Amazon at all (only accessories and one unrelated corded model are). We replaced both rather than recommend a listing with no manufacturer warranty behind it.
5 String Trimmers for Cleaner Lawn Edges and Tight Spaces Buying Questions
Why isn't there a Milwaukee or STIHL trimmer on this list?
We started with both, but neither cleared verification. Milwaukee Tool does not authorize Amazon as a retailer, so every M18 FUEL trimmer listing on Amazon comes from a third-party reseller outside Milwaukee's distribution network, meaning no manufacturer warranty and a real risk of old stock or counterfeits. STIHL is dealer-network-only for its battery and gas trimmers; its Amazon presence is limited to trimmer line and small parts, not the FSA 80 R itself. We swapped in the Makita XRU15PT and the Greenworks Pro ST80L210, both of which are sold directly and currently in stock on Amazon.
Does a higher battery voltage mean more cutting power?
Not directly. Voltage is a brand-specific number, not a universal power unit; EGO's 56V, Greenworks' 80V, RYOBI's 40V HP, Makita's 36V (18V x2), and DEWALT's 60V MAX all use different battery chemistries and motor tuning, so a 40V RYOBI can out-cut an 80V competitor depending on the motor and gearing. Cutting swath width, line diameter, and stated RPM are better apples-to-apples comparisons than voltage alone.
Is it cheaper to buy a bare tool or a kit?
It depends on what batteries you already own. A kit like the RYOBI RY402110 (battery and charger included) or the Greenworks ST80L210 (battery and charger included) is usually the better deal for a first purchase into a battery platform. A bare tool like the DEWALT DCST972B only makes sense if you already own a compatible 60V MAX FLEXVOLT (or backward-compatible 20V MAX) battery and charger; otherwise you're adding $100-plus to the sticker price to buy them separately.
