Quick Answer: Greenworks 40V 18″ vs EGO 18″ — Which Should You Buy in 2026?
Choose the Greenworks 40V 18″ if you want a complete, ready-to-cut package with an included 5.0Ah battery and charger, plus a broad 40V tool ecosystem. Choose the EGO 18″ if maximum listed cutting speed, longer claimed 4×4 cutting capacity, and electronic controls matter more than upfront completeness. The EGO costs only $8.01 more as listed—$309.00 versus $300.99—but its battery and charger are sold separately, making the real purchase cost higher unless you already own an EGO 56V battery.
Winner by Category
| Category | Winner | Evidence |
|---|---|---|
| Power/Suction | EGO 18″ | The EGO lists a 2,500W high-efficiency brushless motor, chain speeds up to 22 m/s, and power equivalent to a 50cc gas saw. Greenworks lists a 40V HP brushless motor and gas-like power for firewood, pruning, and storm cleanup, but does not provide a wattage or chain-speed figure in the supplied data. |
| Cutting performance | EGO 18″ | Its stated capacity reaches up to 330 cuts on 4×4 lumber with a recommended 56V 6.0Ah ARC Lithium battery, compared with Greenworks’ stated 250 cuts on 4×4 lumber. Both use an 18-inch bar. |
| Navigation/Ease of use | EGO 18″ | The EGO adds a digital display for cut-speed controls, battery status, and safety-brake status, along with an LED work light. Greenworks counters with push-button starting, an automatic oiler, and a no-priming/no-pulling design. |
| Vibration/Handling | Greenworks 40V 18″ | Greenworks’ product data emphasizes hassle-free, fume-free operation and a 5.0Ah kit. The supplied data does not provide comparable tool or battery weight for Greenworks, while the EGO is listed at 10.6 lb bare and 16.8 lb with a 6.0Ah battery in the research. This is a close category; Greenworks wins narrowly for the simpler ready-to-use package, not for a measured vibration advantage. |
| Runtime/Battery | EGO 18″ | EGO claims up to 330 4×4 cuts with the recommended 56V 6.0Ah battery. Greenworks claims 250 cuts with its included 5.0Ah battery. A separate test reported 9.55 minutes of cutting runtime for the EGO Power+ CS1800, but that research model designation differs from the CS1810 product listing here. |
| Noise | Neither clearly wins | No model-specific sound measurement is supplied for either chainsaw. Both are battery-powered, and Greenworks specifically describes its saw as fume-free, but the available data does not establish a noise winner. |
| Price & value | Greenworks 40V 18″ | Greenworks costs $300.99 and includes a 5.0Ah battery and charger. EGO costs $309.00, but its battery and charger are not included. The $8.01 list-price difference therefore understates the Greenworks package advantage for new buyers. |
Pros
- Battery and charger are included, so there is no need to buy power accessories separately.
- Brushless motor design typically offers better efficiency and less maintenance than brushed alternatives.
- Lightweight 9.7 lb build can help reduce fatigue during longer yard jobs.
- Three-year warranty adds useful coverage for a cordless outdoor power tool.
Cons
- Runtime is limited by battery capacity, so extended cutting jobs may require recharging or a spare battery.
- At 9.7 lb, it is still a full-size chainsaw and may feel heavy for some users during overhead work.
- The product data does not provide exact battery runtime, charging time, or all specifications, which makes planning harder.
Overview & Design: The Greenworks 40V 18" Brushless Cordless Chainsaw is a battery-powered chainsaw aimed at homeowners who want a cleaner alternative to gas. It includes a 5.0Ah battery and charger, and its 18-inch bar gives it the reach needed for common yard tasks.
Performance & Key Features: According to the product data, the 40V HP brushless motor is built to deliver gas-like cutting power for pruning, firewood, and storm cleanup. The saw also includes push-button start, an auto oiler, tool-less chain tensioning, and a chain brake, which makes day-to-day use more convenient.
Drawbacks & Considerations: Like most cordless chainsaws, runtime depends on battery capacity, so larger projects may require breaks for charging or an extra battery. It is also not the lightest option at 9.7 lb, and the available data does not list every technical detail such as exact runtime or charging duration.
Verdict: This model makes the most sense for property owners who want a capable cordless chainsaw for routine cutting without gas engine upkeep. It is especially appealing if you already use Greenworks 40V tools or want an all-in-one kit that is ready to work out of the box.
Pros
- Strong 50cc gas-equivalent performance from a cordless platform
- Compatible with all EGO 56V ARC Lithium batteries
- Tool-free tension adjustment improves convenience in the field
- Digital display and LED work light add useful real-world visibility and status feedback
Cons
- Battery and charger are not included, so the total setup cost can be higher
- Runtime depends on the battery chosen and the type of wood being cut
- At 18 inches, it is less compact than smaller trimming saws
Overview & Design: The EGO POWER+ CS1810 is an 18-inch battery-powered chainsaw built around a 2500W brushless motor. It aims to deliver gas-like cutting power in a cordless format, and the digital display, LED work light, and tool-free chain tensioning make it feel modern and practical.
Performance & Key Features: With chain speeds up to 22 m/s and a 50cc gas-equivalent rating, this saw is positioned for routine homeowner cutting, storm cleanup, and general property maintenance. The 18-inch bar, 3/8-inch low profile chain, and metal bucking spikes help support controlled cuts, while compatibility with all EGO 56V ARC Lithium batteries adds flexibility for existing users.
Drawbacks & Considerations: The main limitation is that the battery and charger are sold separately, so first-time buyers need to budget for those essentials. Runtime will also vary based on battery capacity and cutting load, and the saw is not as lightweight or compact as smaller pruning-focused models.
Verdict: The CS1810 is a strong fit for buyers who want a capable cordless chainsaw with useful safety and convenience features. It makes the most sense for EGO battery owners, homeowners handling regular yard work, and anyone who wants a quieter, lower-maintenance alternative to gas.

Performance
Core Performance
Both chainsaws are sized for the same general class of work: each has an 18-inch bar, making either one more substantial than a small pruning saw. Greenworks positions its 40V HP brushless motor for firewood, pruning, storm cleanup, and yard tasks. Its listing claims 250 cuts through 4×4 lumber and says the 18-inch cutting system can cut trees or limbs up to 32 inches in diameter. That diameter statement should be treated as a product claim rather than a promise that every user can safely complete every cut.
EGO provides more performance detail. Its 2,500W brushless motor is described as equivalent to a 50cc gas saw and can drive the chain at up to 22 m/s. The supplied EGO claim is up to 330 cuts on a 4×4 with a recommended 56V 6.0Ah ARC Lithium battery. On the numbers alone, EGO has the stronger performance case: its claimed 4×4 capacity is 80 cuts higher than Greenworks’ claim, and its chain-speed figure gives buyers a clearer indication of how the saw is configured.
There is an important comparison limit. The marketplace product is identified as EGO CS1810, while one independent runtime source identifies the tested product as EGO Power+ CS1800. That source reported 9.55 minutes of measured cutting runtime and 70.6 total disks for the CS1800. Those results are useful context for the EGO family, but they should not be presented as a verified CS1810 test result. No equivalent independent Greenworks result appears in the supplied research.
Handling & Ergonomics
Greenworks is the more straightforward saw to get working. Its push-button start removes priming and pulling, and the included battery means the box contains the main items needed to begin cutting. The automatic oiler is another practical convenience because the operator does not have to manage oil flow manually during normal use. The listing also emphasizes low-maintenance and fume-free operation, advantages for homeowners moving away from gas equipment.
EGO takes a more information-rich approach. The digital display shows battery charge status, cut-speed controls, and whether the safety brake is on or off. The LED work light can help visibility in dim areas, while the 18-inch bar gives the saw reach for larger limbs and logs than compact models. However, the available research lists 10.6 lb for the bare tool and 16.8 lb with a 6.0Ah battery. That is a meaningful amount of equipment to control during extended work, especially when the saw is being held away from the body.
The available data does not include a measured vibration figure for either model, so it would be misleading to claim that one has superior vibration damping. The handling choice instead comes down to priorities: Greenworks has the simpler, complete kit, while EGO offers more on-tool feedback and a documented bare-tool weight.
Runtime / Fuel & Maintenance
Neither model uses gasoline, so neither requires fuel mixing, a fuel tank, or a pull-start procedure. Greenworks supplies a 5.0Ah 40V battery and a 5A rapid charger, with a stated capacity of 250 cuts on 4×4 lumber. It also says the battery platform works with more than 100 Greenworks 40V tools. For a homeowner who owns no compatible batteries, that included kit is a major part of the value.
EGO’s runtime claim depends on a battery purchased separately: up to 330 cuts on 4×4 lumber with a recommended 56V 6.0Ah ARC Lithium battery. The saw is compatible with all EGO 56V ARC Lithium batteries, which gives existing EGO owners flexibility but leaves first-time buyers with an additional purchase. The independent CS1800 result of 9.55 minutes of measured cutting runtime provides a useful benchmark from the research, although the model-number difference means it should not be treated as a direct CS1810 result.
Best Use Cases
Greenworks is best matched with regular homeowner yard work, pruning, firewood preparation, and storm cleanup when the buyer wants one purchase containing a battery and charger. Its 18-inch bar and stated 32-inch-diameter cutting claim give it a substantial advertised reach, while the 40V platform makes it useful beyond this one tool.
EGO is the better fit for demanding cordless cutting where the operator values speed information, battery feedback, and a higher stated 4×4-cut claim. Its 50cc-equivalent description and 22 m/s maximum chain speed make the intended performance tier clear. It is especially sensible for someone who already has EGO 56V ARC Lithium batteries. Buyers should still match any chainsaw to their training, the wood, and safe cutting practices; an 18-inch bar does not by itself make every large-tree job appropriate.
Maintenance & Running Costs
Battery power simplifies ownership, but neither chainsaw is maintenance-free. Greenworks specifically lists low-maintenance operation and an automatic oiler. The chain still needs appropriate care, and the cutting system will eventually require routine attention. The supplied listing includes tool-less maintenance wording, but the source text is truncated, so this comparison does not assign a more specific tool-less adjustment feature than the data supports.
EGO’s supplied information identifies the chain as a 3/8-inch low-profile design with a 0.50-inch gauge and 62 drive links. Those details are useful when identifying replacement chain components, but the research does not provide a replacement-chain price, oil-reservoir capacity, or service interval. Greenworks’ chain pitch, gauge, and drive-link count are not provided here, so buyers should confirm replacement specifications before ordering consumables.
The largest running-cost difference is the battery ecosystem. Greenworks includes its 5.0Ah battery and 5A rapid charger at $300.99. EGO includes neither at $309.00, so a new EGO buyer must budget for a compatible 56V ARC Lithium battery and charger. Conversely, an existing EGO owner may avoid that additional cost by using a battery already on hand. The same logic applies to Greenworks owners with a 40V battery, although this particular Greenworks package already includes one.
Features & Usability
The Greenworks design focuses on removing friction from ordinary yard work. Push-button starting eliminates priming and pulling, while the automatic oiler reduces one recurring operational task. The included battery and charger make the purchase easy to understand: the customer is buying a complete cordless chainsaw kit rather than only the saw body. Compatibility with more than 100 Greenworks 40V tools also makes the battery more useful if the household already uses that platform.
EGO’s feature set is more electronic. The digital display combines cut-speed controls with battery charge information and a safety-brake on/off indicator, so the operator receives more feedback than a basic start-and-cut interface provides. The LED work light and adjustable LED work-light functions are also listed. These features may be helpful when work conditions change, although the supplied data does not quantify how much runtime is affected by different cut-speed settings or lighting use.
Safety deserves a realistic distinction. EGO explicitly lists a safety brake and an indicator showing its status. Greenworks also lists safety features, but the supplied feature text ends before the exact details are available. Neither product should be treated as risk-free: chainsaws remain high-energy cutting tools, and buyers should follow the manufacturer’s instructions and use appropriate protective equipment.
Price & Value Analysis
At the product-page level, Greenworks is $300.99 and EGO is $309.00, a difference of just $8.01. That comparison changes once package contents are considered. Greenworks includes a 5.0Ah battery and a 5A rapid charger. EGO’s listing explicitly says battery and charger are not included. Therefore, Greenworks is the stronger value for a first-time cordless chainsaw buyer, even before considering its 250-cut claim and compatibility with more than 100 other 40V tools.
EGO becomes more competitive for an existing EGO 56V customer. If the buyer already owns a compatible ARC Lithium battery, the bare-tool pricing is close, and the EGO offers the stronger listed motor specification, faster stated chain speed, digital controls, and up to 330 claimed 4×4 cuts with the recommended 6.0Ah battery. Its 4.5/5 product rating is also higher than Greenworks’ 4.0/5 rating, although ratings alone do not establish cutting performance.
Greenworks is worth the money when total kit cost matters most and the work is typical homeowner cutting, pruning, firewood, or cleanup. EGO is worth paying for when its electronics and performance claims fit the buyer’s priorities, particularly if an EGO battery is already available. If a buyer must purchase the EGO battery and charger as well, the advertised $8.01 premium is not the relevant cost comparison.
Which Should You Buy?
Choose Greenworks 40V 18″ if…
- You want the most complete package at checkout: the saw, a 5.0Ah battery, and a 5A rapid charger are included.
- You want to spend $300.99 rather than $309.00 before accounting for the EGO battery and charger.
- You already own, or plan to add, other tools in the Greenworks 40V system, which covers more than 100 tools according to the listing.
- You prefer push-button starting, automatic oiling, and a fume-free, low-maintenance alternative to gas equipment.
- Your jobs center on yard cleanup, pruning, firewood, and storm work rather than a need for the most detailed electronic controls.
Choose EGO 18″ if…
- You already own EGO 56V ARC Lithium batteries, so the missing battery and charger are less of a disadvantage.
- You want the stronger listed performance specification: a 2,500W motor, 50cc-equivalent power claim, and chain speed up to 22 m/s.
- You value the up-to-330-cut 4×4 claim with a recommended 56V 6.0Ah battery.
- You want a digital display with cut-speed controls, battery charge status, and a safety-brake on/off indicator.
- You appreciate an LED work light and the detailed 3/8-inch, 0.50-inch-gauge, 62-drive-link chain specification.
Consider a different model if…
- You need a verified model-specific noise, vibration, or runtime comparison that is not provided for both saws here.
- You routinely handle work beyond what you can safely control with an 18-inch battery chainsaw.
- You need a package with a different bar length, a documented weight target, or replacement-consumable details that these listings do not provide.
- You do not already use either battery platform and the total cost of adding batteries and chargers is more important than the listed tool price.
Frequently Asked Questions
Is the Greenworks 40V 18″ more powerful than the EGO 18″?
The supplied specifications favor EGO on published power details. EGO lists a 2,500W brushless motor, up to 22 m/s chain speed, and 50cc-equivalent power. Greenworks lists a 40V HP brushless motor and describes its output as gas-like, but does not provide a comparable wattage or chain-speed figure. That does not prove how every cut will feel, but EGO has the clearer numerical performance advantage in the available data.
Does the EGO 18″ include a battery and charger?
No. The supplied EGO listing says the battery and charger are not included. It is compatible with EGO 56V ARC Lithium batteries, and the runtime claim of up to 330 cuts on 4×4 lumber uses a recommended 56V 6.0Ah battery purchased separately. Greenworks includes both a 5.0Ah battery and a 5A rapid charger.
Which chainsaw has longer runtime?
On the manufacturers’ supplied claims, EGO reaches up to 330 cuts on 4×4 lumber with the recommended 6.0Ah battery, while Greenworks claims 250 cuts with its included 5.0Ah battery. An independent research result measured 9.55 minutes for the EGO Power+ CS1800, but the product listing in this comparison is CS1810, so that result is not a confirmed CS1810 test. Runtime varies with wood, cut length, chain condition, and battery.
Are these chainsaws suitable for big jobs?
Both are 18-inch cordless chainsaws aimed at substantial yard work, but “big jobs” should be defined by the material, the operator’s skill, and safe control rather than bar length alone. Greenworks advertises firewood, pruning, storm cleanup, and cuts through 32-inch-diameter trees or limbs. EGO describes its saw as 50cc equivalent and lists a 2,500W motor. For work that exceeds your training or safe handling ability, a different saw or professional service may be more appropriate.
