Dragging a cord around the yard or mixing gas and oil in a hot garage is a chore no one enjoys. A battery-powered trimmer and blower combo cuts the cord and the fumes, leaving you with a clean, quiet, and instantly ready yard tool system. The only real question is which battery platform to bet your next five years of yard work on.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent countless hours studying battery platform specifications, comparing motor torque curves, analyzing air flow efficiency data, and cross-referencing owner feedback across hundreds of real-world yards to find the combinations that actually hold up season after season.
Whether you are clearing a postage-stamp city lawn or tackling a half-acre suburban plot, finding the right battery trimmer and blower comes down to matching air volume and line diameter to the specific brush and debris you face each weekend.
How To Choose The Best Battery Trimmer And Blower
A trimmer and blower combo is a long-term investment in a battery ecosystem. Choosing correctly means looking past the sticker and weighing the specs that determine whether the tools finish your yard or leave you wrestling with a half-spool of tangled line.
Blower Airflow: CFM vs. MPH
Cubic feet per minute (CFM) measures the volume of air moving through the nozzle — the actual “sweeping” power that moves wet leaves and heavy debris. Miles per hour (MPH) measures the speed of that air, useful for blowing dust off a patio but less critical for clearing a lawn. A blower with 500+ CFM and moderate MPH, like the Husqvarna or EGO models, will clear wet leaves far faster than a high-MPH, low-CFM unit.
Trimmer Line Diameter and Feed System
Thicker line (0.080-inch or 0.095-inch) chews through overgrown grass and light brush without snapping. Thinner line (0.065-inch) is adequate for light trimming but breaks frequently against thick weeds. Automatic or push-button feed systems — such as EGO’s POWERLOAD or WORX’s Command Feed — save the frustration of manually bumping the head on the ground every minute.
Battery Voltage and Amp-Hour Rating
Higher voltage (40V or 56V) generally delivers more torque to the trimmer head and higher CFM to the blower fan. Amp-hour (Ah) rating defines runtime — a 4.0Ah battery lasts roughly twice as long as a 2.0Ah battery under the same load, but also adds weight. Combo kits typically include one battery that you share between tools, so daily recharge becomes part of the workflow.

In‑Depth Reviews
1. EGO POWER+ ST6703LB
The EGO POWER+ ST6703LB combo delivers a 15-inch cutting swath with 0.095-inch professional-grade dual-line twist, giving it the thickest, most aggressive line in this roundup. The 56V battery platform provides enough torque to slice through heavy grass and saplings without bogging down, and the blower pushes 670 CFM at up to 180 MPH — enough to move wet oak leaves off a lawn in a single pass.
The standout feature is the POWERLOAD line feed system: push a button and the trimmer automatically winds new line in seconds, eliminating the frustration of manual spool loading. The variable speed control on the blower ranges from 250 to 530 CFM, plus a turbo boost for tough spots. The telescoping aluminum shaft adjusts to the user’s height, reducing back strain during extended sessions.
On the downside, the 4.0Ah battery is shared between both tools, meaning you’ll need to recharge before finishing a large yard if you use both continuously. The 21.76-pound total kit weight is heavier than most competitors, though much of that weight is in the substantial battery. For medium to large properties, the EGO platform justifies its premium positioning with raw cutting and clearing power.
What works
- Thick 0.095-inch dual-line cuts heavy brush effortlessly
- POWERLOAD auto-feed spool saves time and frustration
- 670 CFM blower clears wet leaves with ease
- Telescoping aluminum shaft fits different user heights
What doesn’t
- Single 4.0Ah battery requires careful runtime planning
- Heavier than most competing combo kits
2. Husqvarna 350iB
The Husqvarna 350iB is a blower-first combo, but its 800 CFM at 200 MPH makes it the undisputed king of leaf clearing in this category. The brushless motor is paired with a 7.5Ah 40V battery that delivers extended runtime, and the power boost mode adds 20 percent more thrust for the heaviest debris piles. The 10-pound weight with the massive battery is actually 15 percent lighter than comparable units, reducing fatigue during long cleanup sessions.
The cruise control keypad lets you lock in a speed setting, so you’re not holding a trigger for 30 straight minutes. The built-in debris scraper at the nozzle edge helps loosen wet, sticky leaves that cling to the ground. On the trimming side, Husqvarna’s 350iB is designed as a standalone leaf blower product, so it does not include a dedicated string trimmer in this specific kit — this is a blower-only powerhouse bundled with a battery and charger for users who already own a trimmer on the same platform.
If you already have a Husqvarna trimmer or plan to buy one separately, this blower is unmatched. For those needing a true two-tool kit, the absence of a trimmer in this box is the critical limitation. The 40V platform is shared across all Husqvarna handheld tools, so expanding is easy, but the initial buy-in is higher.
What works
- 800 CFM at 200 MPH clears wet leaves faster than any competitor
- 7.5Ah battery provides exceptional runtime
- Power boost mode delivers 20% extra thrust
- Cruise control lock eliminates trigger fatigue
What doesn’t
- Kit does not include a string trimmer
- Premium price point for blower-only setup
3. DEWALT DCKO215M1
The DEWALT DCKO215M1 leverages a gear drive transmission on the string trimmer, which mechanically multiplies torque to the cutting head. This design allows the 0.080-inch line to power through thick overgrowth and saplings that would stall a direct-drive trimmer. The 13-inch cutting swath is slightly narrower than the EGO, but the gear drive makes every rotation count against dense weeds.
The blower delivers up to 450 CFM at 125 MPH, which is adequate for dry leaves and grass clippings on driveways and patios. The brushless motor on the blower extends runtime and motor life, and the variable speed trigger lets you dial back power for flower beds. The included 20V MAX battery is part of DEWALT’s massive tool ecosystem, so if you already own DEWALT tools, this combo integrates seamlessly.
The primary limitation is the blower’s moderate air volume — 450 CFM is enough for maintenance but not for heavy wet leaf clearing. The kit includes only one battery, so you’ll need to rotate charging between extended sessions. For DEWALT loyalists with existing batteries and chargers, this combo offers exceptional value and mechanical robustness.
What works
- Gear drive trimmer chews through overgrowth without stalling
- 0.080-inch line resists snapping in thick brush
- Integrates with the DEWALT 20V tool ecosystem
- Brushless blower motor extends runtime
What doesn’t
- Blower’s 450 CFM struggles with wet leaves
- Single battery limits continuous use
4. Makita XT287SM1
The Makita XT287SM1 uses an 18V LXT platform with a brushless motor that delivers 6,000 RPM on the trimmer and 459 CFM at 116 MPH on the blower. The in-line fan blower design — where the fan sits in line with the tube rather than at the motor housing — provides noticeably better balance, reducing wrist strain during prolonged blowing sessions. The cruise control lever on the variable speed trigger lets you lock in a consistent airflow rate.
The trimmer features a high/low speed button for power management, allowing you to conserve battery during light trimming and unleash full RPM for thicker growth. The 18V platform is lighter than 40V or 56V systems, making the kit comfortable for smaller users or those with arthritis concerns. The included 4.0Ah battery provides solid runtime for an 18V system, and the Makita battery ecosystem is one of the most extensive in the tool industry.
The trade-off for the lighter weight is raw power — 459 CFM at 116 MPH is respectable but sits below the premium 56V competitors. The 18V platform also means the trimmer may struggle with very thick brush that a 40V or 56V trimmer handles easily. For yard maintenance on smaller properties where ergonomics and weight matter more than brute force, the Makita is a refined choice.
What works
- In-line fan design offers excellent tool balance
- Cruise control lever reduces trigger fatigue
- Lighter weight ideal for extended use
- High/low speed button extends battery runtime
What doesn’t
- 459 CFM is adequate but not class-leading
- 18V platform lacks torque for heavy brush
5. Milwaukee M18 3000-21
The Milwaukee M18 3000-21 is built around the Quik-LOK system, which allows the trimmer head to be swapped for other attachments (edger, pole saw, or cultivator) without buying a separate tool. This modular design makes it a platform for years of yard maintenance rather than just a two-tool kit. The brushless motor delivers a 16-inch cutting swath with aggressive line management, and the blower provides strong clearing performance.
The kit includes three M18 batteries, which is a significant advantage over competitors that include only one. Three batteries mean you can rotate through a full day of trimming and blowing without waiting for a recharge. The M18 platform is shared with Milwaukee’s extensive power tool lineup, so if you already own Milwaukee tools, this combo expands your outdoor capability without learning a new battery system.
The primary considerations are weight and cost. The 20-pound kit with three batteries is on the heavier side, and the premium price reflects the Quik-LOK system’s versatility. The blower’s specific CFM and MPH ratings are not disclosed in the specs, so performance relative to dedicated blowers like the Husqvarna is unclear. For professionals or serious homeowners already invested in Milwaukee, the modular flexibility justifies the investment.
What works
- Quik-LOK system accepts multiple attachments
- Three batteries included for all-day runtime
- 16-inch swath covers ground quickly
- Integrates with M18 power tool ecosystem
What doesn’t
- Heavy kit at 20 pounds
- Blower CFM/MPH specs not clearly stated
6. Greenworks CK24L4242
The Greenworks CK24L4242 is a three-tool system that includes a 20-inch brushless mower, a 12-inch string trimmer, and a 320 CFM blower, all powered by two 24V batteries. The 48V (24V x 2) configuration provides ample power for the mower’s steel deck and 7-position height adjustment, while the trimmer handles edging and light trimming. The dual-port fast charger recharges both batteries simultaneously, minimizing downtime between sessions.
For homeowners with a medium-sized yard who want a complete cordless solution from mowing to cleanup, this kit eliminates the need for separate purchases. The 320 CFM blower (up to 90 MPH) is best suited for dry debris on hard surfaces rather than wet leaf piles. The automatic feed spool on the trimmer simplifies line management, though the 0.065-inch line is lighter than the heavy-duty options from EGO or DEWALT.
The 71-pound total kit weight is substantial, but that includes the mower, trimmer, blower, two batteries, and charger. The 3-in-1 mower function (mulch, bag, side discharge) adds versatility. The primary drawback is the blower’s lower CFM rating — it won’t replace a dedicated leaf blower for heavy fall cleanup. For steady weekly maintenance, this all-in-one package delivers unmatched convenience.
What works
- Complete mowing, trimming, and blowing in one kit
- Dual-port fast charger reduces downtime
- 20-inch steel deck mower with 3-in-1 function
- 48V (24V x 2) system provides strong mowing torque
What doesn’t
- Blower’s 320 CFM is low for heavy leaf piles
- 0.065-inch trimmer line breaks in thick growth
7. WORX WG927
The WORX WG927 runs on two 20V Power Share batteries in series to produce 40V of power, and those same batteries are compatible with all WORX 20V, 40V, and 80V tools. This cross-platform compatibility makes it a smart foundation for building a cordless yard tool fleet without being locked into a single voltage. The turbine fan design on the blower produces 430 CFM at 90 MPH, while the three-speed plus turbo mode gives fine-grained control over airflow.
The Command Feed system on the trimmer is a standout — press a button on the head and the line feeds instantly, eliminating the need to bump the head on the ground. The variable speed throttle on the trimmer lets you increase RPM for tough grass and dial back for lighter trimming to conserve battery. The 13-inch cutting swath is standard for the mid-range class, and the included two batteries provide decent runtime for both tools.
Where the WORX falls short is top-end power — the 40V (2x20V) system is effective but doesn’t match the raw torque of a dedicated 56V platform like EGO. The 430 CFM blower is strong for dry debris but slows down with wet leaves. For homeowners who prioritize battery ecosystem flexibility and want to expand into other WORX tools over time, the WG927 offers exceptional value.
What works
- Power Share batteries work across WORX 20V/40V/80V tools
- Command Feed button eliminates bump-head frustration
- Turbine fan blower with 3 speeds plus turbo
- Two batteries included for shared runtime
What doesn’t
- 40V system lacks torque of higher-voltage platforms
- Blower struggles with wet, heavy leaves
8. CRAFTSMAN CMCK297M1
The CRAFTSMAN CMCK297M1 is a straightforward, reliable V20 combo that focuses on ease of use. The trimmer features a two-speed setting that lets you choose between more power for thick grass or more runtime for lighter trimming. The automatic line advance feeds 0.065-inch line without bumping — just start the trimmer and the line feeds automatically, keeping you working without interruption.
The blower uses a brushless motor with an axial fan design that delivers 350 CFM at 100 MPH. The variable speed trigger allows precise control between power and runtime. The turn-to-edge function lets you rotate the trimmer head 90 degrees for edging along driveways and sidewalks without changing attachments. The included 4.0Ah battery provides solid runtime for a 20V system.
The 350 CFM blower is the weakest link here — it’s fine for patios and light leaf clearing but not designed for heavy fall cleanup. The 0.065-inch line is thinner than the heavy-duty options, making it prone to snapping in thick brush. For homeowners with smaller, well-maintained lawns who need a fuss-free combo for weekly maintenance, the Craftsman delivers reliable performance without complexity.
What works
- Automatic line advance eliminates bumping
- Two-speed trimmer balances power and runtime
- Turn-to-edge function for quick edging transitions
- Brushless blower motor improves efficiency
What doesn’t
- 350 CFM blower is weak for wet or heavy debris
- 0.065-inch line breaks in thick growth
9. SKIL CB7478C-11
The SKIL PWR CORE 40 CB7478C-11 delivers a surprising 500 CFM from its turbine fan blower — matching or exceeding many mid-range competitors at a lower investment. The digital brushless motor provides efficient power without the maintenance of gas, and the power boost feature amplifies blower power when you need extra clearing force. The 14-inch cutting swath on the trimmer covers ground efficiently for medium-sized yards.
The Twist Load head design simplifies line replacement: insert the line and twist the spool to lock it in, avoiding the frustration of traditional spool winding. The variable speed lever on the trimmer includes cruise control, allowing you to set a consistent speed and focus on cutting. The 2.5Ah battery is smaller than the 4.0Ah options in premium kits, but it keeps the overall weight at a manageable 13.2 pounds.
The trade-off is in battery capacity — the 2.5Ah battery provides enough runtime for a single session on a small yard, but you’ll likely need a second battery for larger properties. The blower’s 500 CFM is a pleasant surprise at this price, though the trimmer lacks the torque of gear-drive or higher-voltage systems for heavy brush. For budget-conscious buyers who want 40V performance without the premium price, the SKIL combo is a strong entry point.
What works
- 500 CFM blower at a budget-friendly price point
- Twist Load head makes line replacement simple
- Digital brushless motor provides efficient power
- Lightweight 13.2 pounds reduces fatigue
What doesn’t
- 2.5Ah battery limits runtime
- Trimmer lacks torque for thick overgrowth
Hardware & Specs Guide
CFM vs. MPH — What Matters
CFM (cubic feet per minute) measures the volume of air a blower moves. MPH (miles per hour) measures the speed of that air. For moving wet leaves and heavy debris, CFM is the more important number — a 500+ CFM blower with moderate MPH will clear a lawn faster than a 350 CFM blower with high MPH. High MPH is useful for dislodging debris from tight spaces like between fence boards or under shrubs, but CFM does the heavy lifting on open lawns.
Brushless Motor Benefits
Brushless motors replace physical carbon brushes with electronic commutation, reducing friction, heat, and energy loss. The practical result is 30-50 percent longer runtime per battery charge, lower vibration levels that reduce hand fatigue, and significantly longer motor lifespan — often 5-10 years of regular use. Every product in this roundup uses a brushless motor, which has become the industry standard for battery-powered outdoor tools.
Line Diameter and Feed Systems
Trimmer line diameter directly determines cutting capability. 0.065-inch line is suitable for light grass and edging along sidewalks. 0.080-inch line handles thicker grass and light weeds. 0.095-inch professional-grade line (used by the EGO ST6703LB) cuts through heavy brush, saplings, and dense overgrowth. Feed mechanisms range from manual bump-feed (tap the head on the ground) to automatic feed (line advances without action) to push-button feed (like WORX Command Feed or EGO POWERLOAD).
Battery Voltage and Amp-Hours
Battery voltage (18V, 20V, 40V, 56V) correlates with the tool’s maximum power output — higher voltage systems deliver more torque to the trimmer and more CFM to the blower. Amp-hours (Ah) indicate energy storage capacity — a 4.0Ah battery delivers roughly twice the runtime of a 2.0Ah battery under the same load. Most combo kits include one battery shared between both tools, meaning the blower and trimmer cannot run simultaneously. Premium kits like the Milwaukee M18 include three batteries for continuous rotation.
