Best Cordless String Trimmers in 2026

This comparison table shows all 15 cordless string trimmers we tested side by side. Notice the clear progression in cutting swath, runtime, and features as you move up the price range. Battery voltage correlates with power, but runtime depends more on amp-hour capacity and motor efficiency.

1. EGO Power+ ST1623T – Premium Choice with Line IQ Technology

I spent three full weekends testing the EGO ST1623T on a half-acre property with thick fescue and invasive weeds. The Line IQ technology genuinely works as advertised. The trimmer senses line wear and automatically extends fresh line before you even notice any reduction in cutting diameter. This eliminated the constant bump-feeding that interrupts workflow with lesser trimmers.

The PowerLoad system deserves special mention. I threaded fresh line through the head, pushed a button, and watched it wind itself perfectly in seconds. No more disassembling spools or wrestling with tangled line. The telescopic carbon fiber shaft adjusted perfectly for my 6-foot frame and felt light despite the larger 4.0Ah battery.

Runtime testing with the included 4.0Ah battery yielded 58 minutes of continuous trimming through moderate grass. That translates to roughly 90 minutes of real-world use with typical start-stop operation. The 16-inch cutting swath let me clear wide paths through overgrown areas that would take significantly longer with 12-inch models.

Cutting performance impressed me most when tackling thick stalks and woody weeds near fence lines. The 0.095-inch dual line combined with the brushless motor delivered clean cuts through vegetation up to half-inch diameter. Variable speed control let me throttle down for delicate edging work around flower beds without throwing debris.

The carbon fiber shaft carries a lifetime warranty, which suggests EGO expects this component to outlast everything else. Build quality feels professional-grade throughout, from the rubber overmold grip to the solid connection points. At 7.5 pounds with battery, it balances well despite the weight.

Who Should Buy This Trimmer

Homeowners with larger properties who want the best cordless technology available will appreciate the ST1623T. The Line IQ system alone justifies the premium for anyone who trims regularly and hates bump feeding. If you already own EGO 56V tools, battery compatibility makes this an easy choice.

Who Should Skip It

Budget-conscious buyers with small lawns under 2,000 square feet do not need this level of technology. The price premium over basic models exceeds $200, which only makes sense for frequent users or those with significant trimming needs.

2. EGO Power+ ST1511T – Best Value with PowerLoad Technology

The EGO ST1511T delivers nearly identical cutting performance to its bigger sibling at a significantly lower price point. I tested this model on the same property and found the 45-minute runtime with the 2.5Ah battery sufficient for most residential trimming sessions. The 15-inch cutting swath covers ground quickly while remaining maneuverable in tight spaces.

PowerLoad technology transforms the frustrating task of loading trimmer line into a 10-second process. I demonstrated this to neighbors who immediately wanted to know which model I was using. The telescopic aluminum shaft provides excellent rigidity while keeping weight reasonable at 10.27 pounds with battery installed.

Cutting power surprised me given the lower price than the ST1623T. The brushless motor maintains consistent RPM under load, and the dual-line spiral twist configuration slices through thick grass without bogging down. Variable speed trigger control lets you match power to the task at hand.

Weather resistance adds peace of mind for unpredictable climates. The IPX4 rating means accidental splashes or light rain will not damage the electronics. I used this trimmer in damp morning conditions without issues, though I still recommend storing batteries indoors.

The EGO 56V battery platform represents one of the best investments in outdoor power equipment. Compatibility with mowers, blowers, chainsaws, and other tools means your battery collection works across your entire yard care arsenal. The fan-cooled charger restores full power in about 50 minutes.

3. EGO Power+ ST1502SA – Rapid-Reload Simplicity

The ST1502SA offers the same excellent 56V power platform as other EGO trimmers with a simplified Rapid-Reload head instead of PowerLoad. This trade-off saves money while maintaining professional-grade cutting capability. During testing, the 15-inch swath cleared paths through overgrown areas that choked lesser trimmers.

Rapid-Reload works by threading line through the head and twisting to wind it securely. While not as automated as PowerLoad, the process takes under 30 seconds and eliminates the puzzle of traditional bump heads. The split shaft design accepts attachments like edgers and hedge trimmers, adding versatility.

Weight distribution impressed me most. At 7.4 pounds, this trimmer feels lighter than its actual weight thanks to excellent balance between motor and battery. I trimmed for 40 minutes straight without shoulder fatigue, a testament to the ergonomic design. The variable speed control provides precision for edging work.

Real-world runtime with the 2.5Ah battery yielded 35-40 minutes of continuous cutting. This translates to roughly an hour of typical use with stops and starts. The fan-cooled charger replenishes the battery in about 50 minutes, so a second battery enables continuous work for larger properties.

The Rapid-Reload head occasionally requires more frequent line advancement than the PowerLoad system. I found myself tapping the head on the ground every few minutes rather than the automatic feeding of higher-end models. This minor inconvenience saves $50-80 over PowerLoad-equipped trimmers.

Who Should Buy This Trimmer

Users wanting EGO power and reliability without premium features should choose the ST1502SA. The split shaft compatibility with attachments adds value for those planning to expand their tool collection. It suits homeowners with moderate trimming needs who value simplicity.

What to Look for When Buying a Cordless String Trimmer

Choosing the right cordless string trimmer requires understanding how you will use it. Our testing revealed significant differences between models that specifications alone cannot capture. Consider these factors before making your decision.

Battery Voltage and Runtime

Voltage correlates with power, but runtime depends on amp-hour capacity. A 20V trimmer with a 5.0Ah battery outlasts a 40V model with a 2.0Ah battery despite lower voltage. Consider your property size when evaluating runtime claims. Small lawns under 3,000 square feet work fine with 20-30 minute runtime. Larger properties need 40+ minutes or spare batteries.

Battery platform compatibility matters for long-term value. EGO’s 56V system, DEWALT’s 60V FlexVolt, and BLACK+DECKER’s 20V/40V platforms all offer extensive tool lineups using the same batteries. Investing in a battery ecosystem saves money when expanding your outdoor power tool collection.

Cutting Swath and Line Diameter

Cutting swath determines how much ground you cover with each pass. Larger 15-16 inch swaths clear wide paths efficiently but become unwieldy in tight spaces. Smaller 10-12 inch swaths maneuver better around obstacles but require more passes for open areas. Choose based on your typical trimming environment.

Line diameter affects cutting capability. Standard 0.065-inch line handles regular grass and light weeds. Heavy-duty 0.095-inch or 0.105-inch line tackles thick vegetation and woody stems. Dual-line configurations cut more aggressively than single-line setups.

Weight and Ergonomics

Weight distribution matters more than total weight. A well-balanced 10-pound trimmer feels lighter than a poorly balanced 7-pound model during extended use. Look for adjustable auxiliary handles and telescoping shafts to customize fit for your height and arm length.

Vibration control reduces fatigue during long sessions. Premium models feature brushless motors and isolation mounts that minimize vibration transmission to your hands. Reduced vibration designs particularly benefit users with arthritis or carpal tunnel concerns.

Line Feed Systems

Traditional bump-feed systems require tapping the head on the ground to advance line. While reliable, this interrupts workflow and wears out trimmer heads over time. Automatic feed systems advance line when the motor starts or through sensor technology.

EGO’s PowerLoad system represents the current pinnacle of line management, automatically winding fresh line with a button press. Line IQ technology senses line length and advances automatically before it gets too short. These innovations justify premium pricing for frequent users.
