Anyone who maintains a yard understands that finding the right string trimmer can be surprisingly challenging. The perfect balance of power, ergonomics, and convenience often seems elusive, with each option presenting its own set of compromises. After years of battling temperamental gas trimmers and underwhelming electric models (including my recent Harbor Freight Bauer 20V), I finally decided to invest in something that promised to address the persistent issues I’ve encountered throughout my lawn care journey.
The EGO Power+ ST1623T cordless string trimmer with 4.0Ah battery and charger caught my attention primarily because of its reputation for power, adjustable shaft length (crucial for someone of my height), impressive battery performance, and innovative line loading system. And, at the time of my purchase, price, as it was on sale. After considerable research and comparison shopping, I purchased this model in May 2024 and have now used it through an entire growing season in varying conditions. This review represents my honest assessment based on my own substantial hands-on experience.
First Impressions
When the sizeable box arrived from Amazon (purchased with my own money, no manufacturer incentives here, not that it would have swayed my assessment), I was immediately struck by the robust build quality. The trimmer feels substantial—perhaps even a bit hefty despite its carbon fiber shaft—but the design suggests serious capability rather than flimsy compromise. The adjustable shaft immediately caught my attention as a taller person who’s spent years hunched over inadequately sized trimmers.
The initial setup process proved straightforward, with clear instructions and intuitive assembly. While the battery arrived with a partial charge, I opted to fully charge it before my first use, which provided an opportunity to evaluate the charging system as well.
Power That Rivals Gas Without the Headaches
The EGO Power+ doesn’t just compete with gas trimmers; in many ways, it stands as a worthy alternative. The variable speed trigger provides impressive control, allowing for delicate edging around garden beds and then ramping up to slice through thick, overgrown grass along fence lines. When confronted with stubborn weeds growing through driveway cracks, the trimmer powered through without bogging down.
What’s particularly refreshing is achieving this level of performance without the ritual of mixing fuel, pulling starter cords, or breathing in exhaust fumes. The ability to simply grab the trimmer and start working immediately cannot be overstated as a quality-of-life improvement. This instant readiness factor, combined with the minimal maintenance requirements, represents a significant advantage over traditional gas-powered equipment.
Battery Life and Charging: A Pleasant Surprise
The included 4.0Ah battery provides ample runtime for my moderate-sized suburban lot—I can typically complete all my trimming on a single charge with capacity to spare. The charging system, while admittedly bulky, replenishes the battery surprisingly quickly, minimizing downtime between jobs.
For those with larger properties, you might consider either a second battery or upgrading to one of EGO’s larger capacity options. However, the efficiency of the motor means you’ll likely get more work done per charge than you might expect. During my testing, I found the battery indicator to be reasonably accurate, providing useful feedback about remaining capacity throughout operation.
It’s worth noting that while the battery and charger size may present storage challenges for those with limited space, this reflects the substantial power capacity rather than a design shortcoming. The trade-off between size and performance seems reasonable given the capabilities provided.
The Game-Changer: Line IQ and Loading System
Perhaps the most revolutionary feature of this trimmer for me is the line loading and management system. Anyone who has spent frustrating minutes (or hours) trying to wind string onto a traditional trimmer head will appreciate the thoughtfulness of EGO’s design.
The color-coded loading system makes replenishing line genuinely intuitive—simply insert the line through the designated hole until it reaches the matching color on the opposite side, and the trimmer automatically winds it properly. No more fighting with spring-loaded covers or trying to align mysterious internal mechanisms.
The Line IQ feature, which automatically feeds line as needed, works remarkably well once you acclimate to it. The system maintains an appropriate line length without the traditional “bump to feed” approach that often results in either too much or too little line. The 16-inch cutting swath makes quick work of larger areas while still offering precision when needed.
In fairness, there was a short learning curve to optimize the Line IQ system’s performance, but the minor adjustment period yielded significant long-term benefits compared to traditional line management approaches.
Built for Taller Users
As someone who stands well above average height, I particularly appreciate the adjustable shaft. The EGO allows me to trim without stooping or developing back strain, which alone nearly justifies the investment. The ergonomic design distributes weight reasonably well, though I did enhance comfort by adding an inexpensive third-party auxiliary handle (specifically this one: https://www.amazon.com/dp/B0CZ98GK7C).
This adjustable design represents thoughtful engineering that accommodates users of varying heights—a consideration often overlooked in lawn equipment design. The adjustment mechanism itself feels sturdy and maintains its position reliably, even during extended use.
A Balanced Assessment of Limitations
Despite its numerous strengths, the EGO isn’t without limitations that potential buyers should consider. The total weight with battery installed is noticeable, even with its carbon fiber shaft, potentially making it challenging for smaller users or during extended sessions. While the weight contributes to stability during operation, it may present an obstacle for some users.
The included line supply is somewhat modest, though replacements are readily available both from EGO and third-party manufacturers on Amazon. Planning ahead for replacement line is advisable, particularly given how much more enjoyable the trimming process becomes with this system.
Both the battery and charger take up a not-insignificant amount of space in my garage, though this reflects their capacity and capability rather than poor design. Consider this less a criticism and more a planning consideration if storage space is limited. For comparison, a 4.0Ah EGO 56v battery is probably 2.5 times the size and weight of a 5.0Ah Bauer 20v battery.
These limitations, while worth noting, haven’t significantly detracted from my overall positive experience with the trimmer. They represent reasonable trade-offs given the substantial performance benefits.
Warranty and Support Considerations
EGO seems to back their products with a generous warranty period, which provides additional value and peace of mind. While I haven’t personally needed to engage with their customer service, the brand has developed a generally positive reputation for honoring their commitments and addressing issues when they arise.
For those concerned about long-term support, the widespread availability of replacement parts and accessories suggests a product ecosystem designed for durability rather than planned obsolescence—an increasingly important consideration in today’s disposable tool market.
Final Verdict: A Worthwhile Investment
After a full season of use, the EGO Power+ ST1623T has firmly established itself as the most capable and user-friendly string trimmer I’ve owned. The combination of substantial power, battery convenience, thoughtful ergonomics for taller users, and the revolutionary line loading system creates a compelling package that justifies its premium price point.
This positive experience has me seriously considering expanding my collection of EGO Power+ tools—I’m currently eyeing up their 800 series mower, leaf blower, and possibly other offerings like the snowblower. Stay tuned for potential reviews of those additions as I continue my journey toward a gas-free lawn and yard care system.
If you’re tired of fighting with temperamental trimmers and ready for a solution that simply works, the EGO Power+ ST1623T deserves serious consideration. Sometimes the best tool isn’t about flashy features, but rather about eliminating long-standing frustrations—and this trimmer does exactly that.
While no single tool will perfectly suit every user’s needs, the EGO Power+ ST1623T strikes an impressive balance between power, convenience, and thoughtful design that addresses many common string trimmer pain points. For those willing to invest in a quality tool that delivers consistent performance without the traditional headaches, it represents a compelling option worthy of consideration.
