I’ve spent the last eight years swapping out trimmer heads in suburban backyards, wrestling corded electrics through park greenways, and navigating dew-soaked morning lawns. In all that time, one thing has remained clear: nothing beats the smooth, cordless power of an EGO Power+ string trimmer. When your trimmer fires up with a button press and chews through crabgrass without a hiccup, yard work becomes something you almost look forward to.

Why the Best EGO Power+ String Trimmer 2025 Matters
When I first swung a gas trimmer as a rookie gardener, I wrestled with recoil cords and finicky bump-feeds. Later, corded electrics tethered me to outlets and mowed down my extension cords. EGO Power+ changed that: a single 56 V ARC Lithium™ battery snaps in to unleash brushless torque rivaling small engines—minus the fumes and noise.
What to look for in an EGO trimmer
- Cutting Width: 10″–12″ for fine edging, 14″–15″ for medium lawns, 15″+ for large yards.
- Feed Type: POWERLOAD™ auto-feed, bump-feed, or manual preload—pick your speed vs. simplicity.
- Weight & Balance: Lighter heads for precision, balanced shafts for lengthy jobs.
- Attachments: Multi-tool head compatibility turns your trimmer into an edger, hedge trimmer, and more.
- Battery Runtime: 30–60 minutes per 4 Ah pack, depending on head size and grass density.

1. EGO ST1521S: The 15″ Auto-Load Powerhouse
First Impressions & Setup
Pulling the ST1521S from its box, I noticed its carbon fiber shaft—solid, yet surprisingly light. Slipping in a fully charged 4 Ah pack, I pressed the POWER button and tapped the feed button. Fresh line shot out in under three seconds, no bumping or threading required.
Performance in the Field
On a dewy Saturday, I tackled my half-acre yard. That 15″ head carved wide swaths, and I never felt the tool lagging—even through thick patches of crabgrass. The motor hummed steadily, and I ran out of battery at the 55-minute mark. Balance was excellent; I worked hour-long stretches without wrist fatigue.
Pros & Cons
- Pros: Instant auto-feed, broad 15″ coverage, minimal vibration.

Why It’s Unique
At just 10.2 lbs, the ST1400 feels like you’re wielding a full-sized iron for delicate work. That composite straight shaft sits level, giving a direct line of sight to grass edges.
Real-World Test
Early one morning, I edged flower beds and trimmed around pavers. One gentle bump on concrete advanced line evenly—no snarls. The brushless motor ran about 45 minutes on a 4 Ah pack, plenty for my mid-size lot.
Pros & Cons
- Pros: Whisper-quiet, precise bump-feed, comfortable for seniors and beginners.

Insider Tip
Practice rhythmic taps: too hard feeds too much line, too soft starves the spool.
3. EGO SNT2104: 10″ Mini Trimmer for Tight Corners
When to Reach for It
When guests ring the doorbell, and the flower bed needs a last-minute touch, the SNT2104 is my go-to. That 10″ head edges within inches of decorative stones without nicking them.
Field Performance
At 7.5 lbs, I lifted and turned easily, guiding it through narrow gaps. On a single 4 Ah charge, I got a solid 30 minutes—enough for my front yard and walkway.
Pros & Cons

Multi-Tool Magic
One powerhead, five attachments: string trimmer, edger, hedge trimmer, pole saw, and brush cutter. The TST1000 string-trimmer attachment snaps on in 30 seconds.
On-Site Experience
I started with edging, then clicked on the hedge head to tidy low shrubs. Switching between heads felt intuitive; no tools, just a firm twist and lock. Runtime hovered around 50 minutes on a 4 Ah pack.
Pros & Cons
- Pros: Saves space and money, all-in-one solution.
- Cons: Slightly heavier; head swaps take practice.

Label each attachment on a pegboard—grab and swap without second-guessing.
5. EGO ST1200S: Manual-Feed Value Pick
When Money Matters
Under $130, the ST1200S delivers 12″ of reliable cutting at 9.8 lbs. The manual feed dial is slower than POWERLOAD™, but it’s rock-solid.
