Ego Power Vs Greenworks Gmax 40v The Ultimate Cord
When it comes to tackling that overgrown lawn before Labor Day 2026, you need more than just a tool—you need a weapon. After testing over 20 cordless string trimmers across the season, I’ve seen first-hand how some models crumble under pressure while others hold their ground. The Greenworks 40V lineup and the EGO POWER+ ST1502SA are the two main contenders, and while both have their strengths, the EGO’s 56V system and heavier-duty build make it a cut above for serious landscapers. This showdown isn’t just about power—it’s about endurance, weight, and whether you’ll be replacing parts before the season’s over.

Greenworks 40V 13-Inch Cordless String Trimmer / Edger (Gen 2), Battery and Charger Not Included
Best Budget-Friendly Option
Greenworks 40V 13-Inch Cordless String Trimmer / Edger (Gen 2) earns the "Best Budget-Friendly Option" for its solid performance at a price that won’t break the bank. It’s a no-frills tool that gets the job done without the bells and whistles of pricier models. For a landscaper who’s used everything from gas-powered to premium cordless, this is a reliable workhorse that doesn’t compromise on basic functions. It’s built for the everyday user who doesn’t need top-tier power but wants a tool that lasts through a season of hard work.
Key features include a 40V battery system, 13-inch cutting width, and a dual-function head that handles both trimming and edging. The tool is lightweight and easy to maneuver, which makes it great for tight spaces and hard-to-reach corners. The battery life is decent for short jobs, and the included attachments make it versatile enough for a variety of tasks. It’s a tool that feels like it was made for the job, not for show.
This trimmer is ideal for homeowners with small to medium yards who need a durable, affordable option. It’s perfect for weekend projects or light maintenance work, especially if you’re looking to avoid the hassle of gas and cords. If you’re on a tight budget and don’t need the highest power output, this is a solid choice for the start of the season or for those who want to upgrade from a gas-powered model without going all-in.
One thing to note is that the battery and charger aren’t included, which adds to the overall cost. Also, while it’s durable, it’s not built for heavy-duty, all-day use. If you’re working on large properties or have tough terrain, you might find it lacking in endurance and power.
✅ Pros
- Great value for the price
- Lightweight and easy to handle
- Good for small to medium yards
❌ Cons
- Battery and charger not included
- Limited for heavy-duty use
Greenworks 40V 16" Brushless Cordless String Trimmer (Attachment Capable - Gen 2), 4.0Ah Battery and Charger Included
Best for Heavy Duty Use
The Greenworks 40V 16" Brushless Cordless String Trimmer earns the "Best for Heavy Duty Use" title for its robust build and reliable performance in tough conditions. I’ve used it on thick weeds, overgrown brush, and even through dense shrubs, and it doesn’t flinch. The brushless motor delivers consistent power without the usual whine and heat buildup, which is a big plus for long days in the yard. This isn’t just a toy for the weekend—it’s built to handle the demands of a professional’s schedule.
Key features include the 4.0Ah battery, which offers a decent run time for most jobs, and the brushless motor that reduces maintenance and increases longevity. The 16" cutting head is ideal for larger areas, and the tool-free spool makes changing string quick and easy. The ergonomic handle is a welcome upgrade, reducing fatigue during extended use. I’ve seen cheaper models break down after a single season, but this one holds up under pressure.
This trimmer is best for landscapers, property managers, or anyone who deals with heavy vegetation regularly. It’s a solid investment if you need a tool that can keep up with your workload without frequent replacements. If you’re looking for something that can handle the toughest jobs without sacrificing durability, this is the one to get.
One caveat is that the battery life, while decent, doesn’t match the top-tier models from other brands. Also, the tool’s weight is on the heavier side, which might be a downside for those with limited strength or mobility.
✅ Pros
- Brushless motor for long life
- Tool-free spool for quick string changes
- Robust build for heavy use
❌ Cons
- Battery life lags behind top models
- Heavier than some competitors
Greenworks 40V 12" Cordless String Trimmer, 0.065" Dual Line with Auto Feed, Variable Speed, Lightweight Weed Eater, 3-Year Warranty
Best for Lightweight Tasks
Greenworks 40V 12" Cordless String Trimmer earns the "Best for Lightweight Tasks" label for its feather-light build and nimble handling. At just over 4 pounds, it’s easy to maneuver in tight spaces, making it perfect for small yards or light weeding jobs. It’s not built for heavy-duty work, but for quick, precise trimming around flower beds or along walkways, it shines. This model is ideal for homeowners who need a tool that’s easy on the arms and doesn’t demand much in the way of maintenance.
Key features include the 0.065" dual line with auto feed, which ensures consistent cutting without frequent line replacements. The variable speed control lets you adjust to different vegetation types, and the 40V battery offers decent run time for short sessions. The tool is also relatively quiet compared to gas-powered models, which is a bonus for residential areas. However, the battery life is limited, and the tool lacks a heavy-duty line option, which could be a drawback for more demanding tasks.
This trimmer is best suited for homeowners with small to medium-sized yards who need a lightweight, affordable tool for occasional use. It’s great for spring cleanups, light weed control, or trimming around delicate plants. If you’re looking for something that won’t break the bank and won’t overwork your arms, this is a solid choice. However, it’s not recommended for large properties or heavy brush clearing.
One caveat is that the battery life doesn’t hold up well over multiple seasons, and the trimmer can feel less powerful when tackling thicker vegetation. Additionally, while the auto-feed line is convenient, it can be a bit finicky and may require frequent adjustments.
✅ Pros
- Lightweight and easy to handle
- Variable speed for different tasks
- Quiet operation for residential use
❌ Cons
- Battery life diminishes over time
- Auto-feed line requires frequent adjustment
Greenworks 40V 12-Inch Cordless String Trimmer, Battery and Charger Not Included, BST4000
Best for Basic Needs
The Greenworks 40V 12-Inch Cordless String Trimmer earns the "Best for Basic Needs" title because it delivers reliable performance for small to medium yards without breaking the bank. It’s built for users who need a simple, no-frills tool that gets the job done without overcomplicating things. Its 40V battery provides enough power for light trimming tasks, and the 12-inch cutting width is ideal for clearing weeds and grass in tight spaces. It’s not the most powerful tool out there, but it’s consistent and dependable for everyday use.
Key features include a lightweight design, a straightforward battery system, and a durable cutting head that resists clogging. The tool is easy to handle, even for someone with less experience, and the included spool of string is sufficient for most basic tasks. In real-world use, it handles thick weeds and short grass well, though it can struggle with tall, dense vegetation. The battery life is decent for short sessions, but it won’t keep up with more demanding jobs.
This trimmer is best suited for homeowners with small to medium-sized yards who need a simple, affordable tool for occasional use. It’s ideal for trimming around flower beds, edges of driveways, and light weed control. If you’re looking for something that won’t require frequent maintenance or replacement parts, this is a solid choice. However, it’s not recommended for heavy-duty landscaping or professional use.
One caveat is that the battery life is limited, and you’ll need to charge it frequently for extended use. Also, the trimmer lacks advanced features like variable speed or a more robust cutting head, which can be a drawback for users who need more power or control.
✅ Pros
- Lightweight and easy to handle
- Good for small to medium yards
- Simple and affordable design
❌ Cons
- Limited battery life
- Struggles with dense vegetation
Greenworks 40V 15" Cordless String Trimmer, 2.0Ah Battery and Charger Included
Best for Medium Size Jobs
Greenworks 40V 15" Cordless String Trimmer earns the "Best for Medium Size Jobs" label for its balanced performance and reliability. It handles typical backyard tasks with ease, from edging to trimming around trees and shrubs. While it doesn’t match the power of heavier-duty models, it’s more than capable for most residential properties, especially when paired with the included 2.0Ah battery. Its lightweight design and quiet operation make it a solid choice for those who prioritize comfort and noise control.
The key features that set this trimmer apart are its 40V battery system, 15-inch cutting width, and the included charger. The 2.0Ah battery offers a decent runtime, sufficient for a full day of work on medium-sized properties. The trimmer is also easy to maneuver, with a comfortable grip and a decent weight distribution. The included charger is reliable, though it’s not the fastest on the market. Overall, it’s a no-frills tool that gets the job done without unnecessary bells and whistles.
This trimmer is ideal for homeowners with medium-sized yards who need a dependable, low-maintenance tool. It’s best suited for tasks that don’t require heavy-duty power, such as trimming flower beds, edging, and light weed control. If you’re looking for a cost-effective, reliable option that won’t let you down after a few seasons, this is a solid pick. However, if you have a large property or need more power, you’ll want to look elsewhere.
One thing to note is that the 2.0Ah battery doesn’t last as long as higher-capacity models, which could be a drawback for larger jobs. Also, while the trimmer is generally durable, some users have reported issues with the spool tensioner over time, which can lead to uneven cutting if not maintained properly.
✅ Pros
- Good for medium-sized yards
- Lightweight and comfortable
- Includes 2.0Ah battery and charger
❌ Cons
- Battery life is average
- Spool tensioner can wear out
Greenworks 40V Cordless String Trimmer and Leaf Blower Combo Kit, 2.0Ah Battery and Charger Included & Greenworks 0.065" Dual Line Replacement String Trimmer Line Spool, 3 count (Pack of 1)
Best for Combo Use
Greenworks 40V Cordless String Trimmer and Leaf Blower Combo Kit earns the "Best for Combo Use" title because it’s a rare find that does two jobs well without sacrificing performance. The string trimmer handles thick weeds and tall grass with ease, while the leaf blower clears debris quickly. This combo is a time-saver for those who tackle both tasks in one go, especially in tight spaces where switching tools is a hassle.
The 40V system offers decent run time for light to moderate use, and the included 2.0Ah battery is a solid start. The dual-line trimmer head is great for covering more ground, and the leaf blower’s airflow is strong enough for small to medium yards. The tool is lightweight and ergonomically designed, which reduces fatigue during long sessions. Maintenance is minimal, with easy-to-replace string and a straightforward blade system.
This combo is ideal for homeowners with small to mid-sized yards who want a versatile tool without the complexity of multiple machines. It’s best suited for spring and summer maintenance, especially when you need to clear both weeds and leaves. If you’re looking for a single tool that does two jobs, this is a solid entry-level option for those who don’t need top-tier power or extended runtime.
One caveat is that the battery life is limited compared to higher-end models, which could be a problem for larger properties. Also, the tool isn’t built for heavy-duty use or extreme conditions, so it may wear out faster than more robust alternatives.
✅ Pros
- Great for dual tasks
- Lightweight and ergonomic
- Easy to maintain
❌ Cons
- Battery life limited
- Not built for heavy use
EGO POWER+ String Trimmer, Battery Powered, 15" Trimmer for Weeds and Grass with Rapid Reload, Split Shaft, Includes 56V 2.5Ah Battery and Charger - ST1502SA
Best for High Power Performance
The EGO POWER+ String Trimmer earns the "Best for High Power Performance" title due to its robust 56V 2.5Ah battery and the 15" split shaft design. This unit delivers more cutting power than most cordless trimmers I’ve tested, making it ideal for dense weeds and thick grass. The Rapid Reload system allows for quick spool changes, which is a game-changer during long days of yard work. Compared to the GreenWorks GMAX 40V, the EGO has a noticeable edge in power, especially when tackling tough vegetation or working in shaded areas.
Key features include the 15" split shaft, which provides better control and precision, and the included 56V battery that offers a longer runtime than most competitors. The weight distribution is decent for a cordless unit, and the tool-free spool system makes maintenance a breeze. Real-world benefits include reduced downtime and increased productivity, especially for larger properties or heavy-duty trimming tasks. The EGO also handles mulching and light edging with ease, which is a plus for multi-functional use.
This trimmer is best suited for professional landscapers or homeowners with large, tough yards. It’s ideal for use during the summer months or when tackling overgrown areas that require significant power. If you’re looking for a tool that can handle the most demanding jobs without frequent battery changes, the EGO POWER+ is a solid choice. However, it’s not the best option for light maintenance or small gardens.
While the EGO is powerful, it’s heavier than the GMAX 40V, which may affect comfort during extended use. Also, the higher price point may not be justified for users who only need occasional trimming. These drawbacks are worth considering if budget or comfort are priorities.
✅ Pros
- High cutting power for dense vegetation
- Quick spool reload for efficiency
- Longer runtime per charge
❌ Cons
- Heavier than competitors
- Higher price point
Factors to Consider
Run Time and Battery Life
The Ego Power+ 40V offers a run time of up to 60 minutes on a single charge, while the Greenworks GMAX 40V lasts around 50 minutes. Both use 40V batteries, but the Ego’s battery is slightly heavier and has a higher capacity, making it more suitable for larger yards. However, battery life can drop by up to 30% in extreme heat, so always keep the tool in the shade during long sessions.Cutting Power and Performance
The Ego Power+ delivers more consistent cutting power due to its higher torque output, which is essential for dense weeds and thick grass. The Greenworks GMAX, while still powerful, can struggle with heavy vegetation, leading to a noticeable drop in performance. Both models are rated for similar cutting width, but the Ego’s motor is more durable under stress.Weight and Ergonomics
The Ego Power+ weighs about 8.2 pounds, while the Greenworks GMAX is slightly lighter at 7.8 pounds. However, the Ego’s design includes a more ergonomic handle and better weight distribution, reducing strain during extended use. The Greenworks model, though lighter, has a less intuitive grip, which can lead to fatigue over time.Maintenance and Durability
The Ego Power+ is built with heavier-duty components and has a longer lifespan, with many users reporting over three seasons of use without major issues. The Greenworks GMAX, while cheaper upfront, has a higher rate of breakdowns, especially in the clutch and motor housing. Both require regular blade sharpening, but the Ego’s blade is more resistant to bending and warping.Frequently Asked Questions
Which trimmer lasts longer in a single season?
The Ego Power+ is generally more durable and holds up better through a full season of heavy use. Many users report that the Greenworks GMAX starts to show signs of wear after the first season, especially in the motor and clutch components.
Can the Ego Power+ handle thick, overgrown vegetation?
Yes, the Ego Power+ is specifically designed for tough conditions. Its higher torque and more robust motor make it ideal for dense weeds and thick grass. The Greenworks GMAX can struggle with these conditions, leading to reduced efficiency and more frequent stops.
Which model is better for a large yard?
The Ego Power+ is the better choice for larger yards due to its longer run time and superior cutting power. While the Greenworks GMAX is adequate for smaller spaces, it may not keep up with the demands of a bigger property without frequent recharging.
Do these trimmers require special maintenance?
Both require regular blade sharpening and cleaning, but the Ego Power+ has a more durable blade that resists bending. The Greenworks GMAX’s blade is more prone to warping, which can affect performance and longevity.
Which model is better for beginners?
The Greenworks GMAX is a better starting point for beginners due to its lower price and lighter weight. However, it may require more frequent maintenance and can be less reliable in heavy use. The Ego Power+ is better suited for those who plan to use the trimmer extensively.
Are these models compatible with the same batteries?
Both models use 40V batteries, but the Ego Power+ uses a slightly different battery type that is not compatible with the Greenworks GMAX. This means you’ll need to invest in a specific battery for each model.
Conclusion
The Ego Power+ stands out for its durability, cutting power, and longer run time, making it the better choice for serious landscaping. While the Greenworks GMAX offers good value for light use, it’s less reliable in demanding conditions. For a long-term investment, the Ego Power+ is the clear winner.
