As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
Choosing between a 40 ah vs 60 ah leaf blower depends on your runtime needs and power source. Both the EGO Power+ and SKIL PWR CORE 40 offer brushless motors and variable speed controls for effective debris management. The main difference lies in their voltage and battery capacity. The EGO uses a 56V system with a 4.0 Ah battery, while the SKIL relies on a 40V platform with a larger 6.0 Ah battery. This affects how long each tool runs and the peak airflow it delivers.
Key differences

Which one should you choose?
Choose EGO Power+ 56V 670 CFM Handheld Leaf Blower if
- You want the highest air speed and volume for tough debris
- You already own other EGO 56V tools for battery sharing
- You prefer a lighter handheld form factor for quick jobs
Choose SKIL PWR CORE 40V 650 CFM Blower if
- You need longer runtime with a larger battery capacity
- You want a dual-handle design for better control and comfort
- You value weather-resistant construction for outdoor durability
Verdict: The EGO Power+ offers slightly higher peak performance with more air speed and volume. The SKIL PWR CORE provides a larger battery and a more ergonomic dual-handle design for extended use. Choose the EGO for maximum power per charge, or the SKIL for longer runtime and comfort.
4.0 Ah vs 6.0 Ah Leaf Blowers
Voltage and Platform
The EGO Power+ LB6703 operates on a 56V ARC Lithium platform, while the SKIL PWR CORE 40 uses a 40V system. Voltage indicates the electrical pressure the motor receives. Higher voltage often correlates with greater torque and sustained power under load. EGO’s 56V setup is designed to deliver gas-like performance for heavy debris. SKIL’s 40V system is optimized for residential tasks. Your existing tool ecosystem matters here. If you own other 56V EGO tools, the battery shares across them. SKIL batteries work with their 40V lineup. Choose the voltage that matches your current inventory to avoid buying duplicate chargers and cells.
Battery Capacity
This comparison focuses on capacity differences. The EGO unit includes a 4.0 Ah battery. The SKIL kit provides a 6.0 Ah battery. Amp-hours measure how much energy the cell holds. A higher number generally means longer runtime between charges. The SKIL 6.0 Ah cell offers more stored energy than the EGO 4.0 Ah cell. This suggests the SKIL might run longer on a single charge during light to moderate use. However, runtime also depends on airflow settings. Both brands claim specific runtimes. The EGO lists up to 80 minutes. The SKIL does not list a specific minute count in the provided specs. The larger capacity gives SKil a theoretical advantage for extended sessions.
Air Volume
Air volume measures how much air the blower moves, rated in cubic feet per minute (CFM). The EGO Power+ delivers 670 CFM. The SKIL PWR CORE 40 delivers 650 CFM. Higher CFM moves more debris with each pass. The EGO has a slight edge in raw air volume, producing 20 CFM more. This difference is modest but noticeable when clearing large lawns or thick layers of leaves. Both units exceed the 600 CFM threshold for serious yard work. The EGO’s higher volume makes it marginally more efficient at pushing heavy, wet clumps. If you prioritize maximum displacement per second, the EGO holds a small lead.
Air Speed
Air speed determines how fast the air exits the nozzle, measured in miles per hour (MPH). The EGO reaches 180 MPH. The SKIL reaches 170 MPH. Higher speed helps dislodge stuck debris like wet leaves or grass clippings from pavement. The EGO’s 180 MPH airflow provides more kinetic force to knock stubborn material loose. The SKIL’s 170 MPH is still powerful enough for most residential cleanup jobs. The 10 MPH difference is measurable but not drastic. For delicate tasks like clearing flower beds, lower speed is better. Both offer variable speed controls to adjust output. The EGO wins slightly here due to its higher maximum velocity.
Runtime Claims
Runtime tells you how long you can work before recharging. The EGO Power+ specifies up to 80 minutes of runtime with its 4.0 Ah battery. The SKIL PWR CORE 40 does not provide a specific runtime figure in the available data. This makes direct comparison difficult. The EGO’s claim is transparent and allows you to plan your work. The SKIL’s larger 6.0 Ah battery might offer longer runtime, but without a stated number, it is an assumption. The EGO’s explicit 80-minute window is a clear advantage for planning. You know exactly what to expect. The SKIL leaves you to guess based on capacity alone.
Weight and Ergonomics
Weight affects comfort during extended use. The EGO Power+ weighs 11.7 pounds. The SKIL PWR CORE 40 does not list a weight in the provided specifications. We cannot compare mass directly. However, the SKIL features a dual-handle ergonomic design. This allows you to hold the tool like a shotgun, reducing strain on your wrist and arm. The EGO uses a standard handheld grip. Dual handles often provide better control for drying cars or cleaning gutters. The EGO’s weight is moderate for a handheld unit. Without SKIL’s weight data, we cannot determine which is easier to hold. The SKIL’s handle design offers a functional advantage for specific tasks.
Which Leaf Blower Fits Your Yard
Users needing maximum airflow for heavy debris
The EGO Power+ delivers 670 CFM, the highest air volume in this comparison. This spec helps it move wet leaves and caked grass more effectively than the SKIL. It also reaches 180 MPH air speed. If your yard has dense, heavy debris, this higher airflow and speed provide the power needed to clear paths quickly.
Gardeners wanting longer runtime for large areas
The SKIL PWR CORE 40 includes a 6.0 Ah battery, offering more capacity than the EGO’s 4.0 Ah unit. This larger battery supports longer continuous use before needing a recharge. If you have a large property or prefer not to swap batteries mid-job, the extra capacity ensures you can finish your work without interruption.
Those preferring dual-handle ergonomic design
The SKIL features a dual-handle ergonomic design, which improves control for tasks like clearing gutters or drying car rooftops. This configuration reduces strain during extended use. If you value comfort and stability while working at height or in tight spaces, this handle style offers better maneuverability compared to the single-handheld EGO design.
Users with existing EGO 56V battery tools
The EGO Power+ is compatible with all EGO 56V ARC Lithium batteries. If you already own other EGO tools, you can use your existing batteries with this blower. This platform compatibility saves you from buying additional chargers or batteries, making it a convenient choice for homeowners who are already invested in the EGO ecosystem.
