EGO POWER+ String Trimmer Key Features & Specs
The EGO POWER+ String Trimmer ST1623T is packed with innovative features and robust specifications that set it apart from many competitors. Understanding these details helps to appreciate its advanced design and performance capabilities.
POWERLOAD Technology
This is arguably the most revolutionary feature. POWERLOAD technology eliminates the tedious and often frustrating process of manually winding trimmer line. With the press of a button, the trimmer automatically winds the line for you, saving significant time and effort. This innovation is a game-changer for anyone who has struggled with line reloading.
LINE IQ Technology
Complementing POWERLOAD, LINE IQ is an intelligent line-feeding system that senses when more line is needed and automatically feeds it. This ensures a consistent cutting diameter and prevents the line from wearing down too quickly, optimizing efficiency and reducing interruptions during operation.
56V ARC Lithium Battery System
The trimmer is powered by EGO’s advanced 56V ARC Lithium battery. The included 4.0Ah battery provides ample power and decent run time for most residential tasks. These batteries are known for their rapid charging capabilities and compatibility across the entire EGO 56V tool lineup, offering excellent system value.
Brushless Motor
A high-efficiency brushless motor drives the ST1623T. Brushless motors offer several advantages over brushed motors, including increased power output, longer motor life, reduced noise, and greater energy efficiency, which translates to longer battery run times.

Telescopic Carbon Fiber Shaft
The shaft is constructed from lightweight yet incredibly durable carbon fiber, making the trimmer easy to handle and robust enough for demanding use. Its telescopic design allows for quick adjustment of the shaft length, providing optimal balance and comfort for users of varying heights. This adjustability also makes storage more convenient.
Variable Speed Trigger
The variable speed trigger provides precise control over the cutting speed, allowing users to adjust power output based on the task at hand. This feature is crucial for conserving battery life when tackling lighter growth and unleashing full power for dense weeds or thick grass.
Dual-Feed Line System
The dual-feed head ensures that two lines are always working, providing a cleaner and more efficient cut. This design reduces vibrations and makes the trimming process smoother, especially when dealing with tough vegetation.
Included Components
The ST1623T kit includes not only the trimmer head and shaft but also a 56V 4.0Ah ARC Lithium battery and a standard charger. This comprehensive package ensures that users have everything necessary to begin trimming immediately, without needing to purchase additional accessories.
These features collectively make the EGO POWER+ String Trimmer a highly capable and user-friendly tool. From its innovative line management to its powerful battery system and ergonomic design, every aspect is engineered to deliver a superior trimming experience. The combination of power, convenience, and durability truly sets it apart in the battery-powered outdoor equipment market.
The robust construction, particularly the carbon fiber shaft, ensures that the trimmer can withstand the rigors of regular use in various outdoor conditions. This focus on longevity and performance ensures that the investment in an EGO tool pays off over time.
Pros & Cons
Evaluating the EGO POWER+ String Trimmer ST1623T requires a balanced look at its strengths and weaknesses. This section breaks down the significant advantages and potential drawbacks to help you make an informed decision.
Pros
- Effortless Line Reloading with POWERLOAD: This is a major highlight. The automatic line winding system saves immense time and frustration, making line changes quick and simple. It eliminates the need for manual spooling, a common pain point for many users.
- Intelligent Line Management with LINE IQ: The sensor-based automatic line feed ensures optimal line length for consistent cutting performance. This means fewer interruptions and a more efficient trim, as you’re not constantly bumping the head or dealing with too-short line.
- Powerful, Gas-Like Performance: Thanks to its 56V ARC Lithium battery and brushless motor, this trimmer delivers ample power to cut through thick grass and stubborn weeds. Many users report performance comparable to or even exceeding light-duty gas trimmers, without the associated fumes or maintenance.
- Quiet Operation and Zero Emissions: Operating significantly quieter than gas models, the EGO trimmer allows for more pleasant yard work and won’t disturb neighbors. The absence of exhaust fumes makes it environmentally friendly and healthier for the user.
- Durable and Ergonomic Design: The telescopic carbon fiber shaft is both lightweight and incredibly strong, contributing to the tool’s longevity and ease of handling. Its adjustable length ensures comfortable operation for users of various heights, reducing back strain.
- Part of a Versatile Battery Ecosystem: The 56V ARC Lithium battery is interchangeable with all other EGO POWER+ tools. This means one battery can power your trimmer, leaf blower, chainsaw, and more, offering significant cost savings and convenience if you own multiple EGO products.
- Low Maintenance: Unlike gas trimmers that require fuel mixing, spark plug changes, and air filter cleaning, the EGO ST1623T only needs battery charging and occasional line replacement. This simplifies upkeep and extends the tool’s lifespan.
- Instant Start: No more pull cords or priming. The EGO trimmer starts instantly with the squeeze of a trigger, providing immediate power when you need it. This convenience is a huge advantage over traditional gas models.
Cons
- Premium Price Point: The initial cost of the EGO POWER+ String Trimmer, especially as a kit with battery and charger, is higher than many entry-level gas or corded electric trimmers. This can be a barrier for budget-conscious buyers.
- Battery Run Time Considerations: While the 4.0Ah battery provides good run time for most average-sized yards, very large properties or extensive heavy-duty trimming might require a second battery to complete the job without interruption. Battery life is finite and depends heavily on the intensity of use.
- Weight with Battery: While the carbon fiber shaft is light, the 56V battery adds noticeable weight to the unit. Some users, especially those accustomed to very light corded trimmers, might find it slightly heavier during extended use, although it is still well-balanced.
- Specific Line Gauge: To ensure optimal performance and compatibility with the POWERLOAD system, users are typically recommended to use EGO’s specific trimmer line or a similar gauge. While not a major issue, it’s something to be aware of when purchasing replacement line.
- Charger Speed: While the included charger is effective, it’s not the rapid charger. Charging a completely depleted 4.0Ah battery can take a couple of hours. For users with large properties, investing in a rapid charger might be beneficial for quicker turnaround times.
Overall, the pros of the EGO POWER+ String Trimmer heavily outweigh the cons for most homeowners. The convenience, power, and innovative features provide a superior user experience, justifying the higher initial investment for those seeking a premium battery-powered solution.
Who Should Buy the EGO POWER+ String Trimmer?
Deciding if the EGO POWER+ String Trimmer ST1623T is the right tool for you depends largely on your specific yard care needs, priorities, and budget. This advanced battery-powered trimmer is not for everyone, but it offers exceptional value for certain types of users.
Ideal Users for the EGO POWER+ String Trimmer:
- Homeowners with Medium to Large Yards: If you have a yard that requires more than just a quick trim around the edges, the 16-inch cutting swath and powerful 56V system will make quick work of your tasks. It provides the muscle needed for properties up to an acre, especially with the included 4.0Ah battery.

It delivers impressive torque and cutting ability without the traditional gas engine drawbacks.
- Existing EGO POWER+ System Users: If you already own other EGO 56V tools, this trimmer is a no-brainer. The interchangeable battery system means you can use your existing batteries, potentially saving money by purchasing the tool-only version later, and sharing power across your entire fleet.
- Environmentally Conscious Individuals: For those who prioritize reducing their carbon footprint and minimizing noise pollution, the EGO ST1623T offers a zero-emission, quieter alternative to gas trimmers. It’s a responsible choice for both your personal health and the environment.

If you dread reloading trimmer line or constantly bumping for more, these features alone make the EGO POWER+ String Trimmer incredibly appealing. It streamlines the trimming process significantly.
- Individuals Who Appreciate Durability and Ergonomics: The carbon fiber shaft and overall robust build quality are designed for longevity and comfortable use. If you value tools that are built to last and are comfortable to operate during longer sessions, this trimmer will meet your expectations.

You can trim early in the morning or late in the evening without causing disturbances.
This EGO POWER+ String Trimmer is particularly well-suited for suburban homeowners who want a powerful, reliable, and low-maintenance tool. Its advanced features make yard work less of a chore and more of an enjoyable task.
Who Might Consider Alternatives:
- Budget-Constrained Buyers: If your primary concern is the lowest possible upfront cost, the premium price of the EGO ST1623T might be prohibitive. Cheaper corded or less powerful battery trimmers are available, though they come with compromises.
- Users with Very Small Yards: For tiny urban plots or minimal trimming needs, the full power and features of the EGO might be overkill. A smaller, less expensive option could suffice for light touch-ups.

However, it can serve as an excellent secondary or specialty tool.
- Those Unwilling to Invest in the EGO Ecosystem: If you have no other EGO tools and don’t plan to acquire any, the investment in the battery and charger is solely for this trimmer. While still a great tool, some value is lost if you don’t leverage the interchangeable battery system.
In summary, the EGO POWER+ String Trimmer is an investment in quality, convenience, and performance. It’s best suited for homeowners who are willing to pay a bit more for a premium, hassle-free yard care experience that rivals gas power.
FAQ about EGO POWER+ String Trimmer
Here are some frequently asked questions about the EGO POWER+ String Trimmer ST1623T, providing detailed answers to common inquiries.
Q1: What exactly is EGO’s POWERLOAD technology and how does it work?
A1: POWERLOAD technology is EGO’s patented automatic line winding system. To use it, you simply feed a length of trimmer line through the head until it comes out the other side evenly. Then, you press a button on the trimmer head, and the motor internally winds the line onto the spool automatically. This eliminates the tedious manual winding process, saving time and effort for the user.
Q2: How long does the included 4.0Ah battery last on a single charge?
A2: The run time of the 4.0Ah battery depends on the intensity of the work. For light trimming of grass, you can expect around 45-60 minutes of continuous use. When tackling thicker weeds or consistently using the trimmer at full power, the run time might be closer to 30-40 minutes. For larger properties, having a second battery or a higher capacity battery (e.g., 5.0Ah or 7.5Ah) can be beneficial.
Q3: Is the EGO POWER+ String Trimmer suitable for heavy brush or thick weeds?
A3: Yes, the EGO POWER+ String Trimmer is surprisingly capable of handling heavy brush and thick weeds. Its 56V power system and brushless motor deliver significant torque, allowing it to cut through dense vegetation that might bog down less powerful trimmers. The 0.095-inch line (recommended) is robust enough for these tougher tasks. However, for extremely thick, woody brush, a dedicated brush cutter attachment or tool might be more appropriate.
Q4: Can I use different brands or sizes of string trimmer lines with the ST1623T?
A4: For optimal performance and to ensure proper function of the POWERLOAD system, EGO recommends using their proprietary 0.095-inch twisted line. While other brands of 0.095-inch line may work, consistency with the EGO line is best for the automatic winding mechanism. Using a different size, especially a thicker one, may not fit or could cause issues with the POWERLOAD feature.
Q5: How does the EGO POWER+ String Trimmer compare to a traditional gas string trimmer?
A5: The EGO POWER+ String Trimmer offers comparable power to many medium-duty gas trimmers, but with several advantages. It’s significantly quieter, produces zero emissions, requires no fuel mixing or engine maintenance, and starts instantly. Gas trimmers may still offer slightly longer continuous run times for commercial applications or extreme heavy-duty tasks, but for most homeowners, the EGO provides a more convenient and pleasant experience without sacrificing much power.
Q6: Is the shaft adjustable for different user heights?
A6: Yes, the EGO POWER+ String Trimmer features a telescopic carbon fiber shaft that is fully adjustable. This allows users of different heights to customize the length of the trimmer for optimal comfort and balance during operation. The telescopic design also makes it more compact for storage and transport.
Q7: What is the warranty information for the EGO POWER+ String Trimmer?
A7: EGO typically offers a 5-year limited warranty for the tool and a 3-year limited warranty for the battery and charger when purchased from an authorized retailer for residential use. It’s always best to check the specific warranty terms provided with your product or on the official EGO website, as terms can sometimes vary. For more details, you can visit the EGO POWER+ official website.
Q8: How long does it take to fully charge the included 4.0Ah battery?
A8: Using the standard charger that comes with the ST1623T kit, a fully depleted 4.0Ah ARC Lithium battery typically takes about 80 minutes to fully charge. EGO also offers rapid chargers that can significantly reduce this time, often charging a 4.0Ah battery in around 30 minutes, which can be a worthwhile upgrade for users who need faster turnaround times between tasks.
