Looking for a cordless string trimmer and blower combo means you want one battery platform to handle the two most common yard chores: trimming the edges and clearing the mess afterward. The trick is finding a pair that actually shares batteries well and gives you enough power without making your arms ache.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The eight combos here cover everything from budget sets for small lawns to premium kits that can handle an acre. This guide to the best cordless string trimmer and blower combo breaks down which ones give you the runtime for your yard and which ones cut corners you will notice.
Our Picks at a Glance
How To Choose The Best Cordless String Trimmer And Blower Combo
A combo kit saves you money and shelf space, but the two tools are only as good as the battery they share. Here is what to check before you buy.
Battery Capacity and Voltage
The battery is the heart of any cordless combo. A higher voltage — 40V or 56V vs 20V — usually means more cutting and blowing power for thicker growth and heavier debris. The capacity, measured in amp-hours (Ah), determines how long you can work. A 4.0Ah battery gives longer runtime than a 2.0Ah one, which matters if your yard takes more than 30 minutes to trim and blow.
Blower Airflow (CFM) and Speed (MPH)
CFM (cubic feet per minute) tells you the volume of air the blower moves. More CFM clears wider piles of leaves faster. MPH (miles per hour) tells you the airspeed, which matters for moving wet leaves or stuck debris off a patio. A good combo aims for at least 300 CFM and 100 MPH if you have trees or a driveway to clear.
Trimmer Cutting Width and Feed System
A wider cutting swath (the path the string cuts) means fewer passes along a fence line or around flower beds. Most combos offer 10 to 15 inches. The line feed system matters daily: bump-feed lets you tap the head on the ground to release more line, while auto-feed advances it automatically. Auto-feed is convenient but can jam more often if the grass is thick.

In‑Depth Reviews
1. BLACK+DECKER 20V MAX Weed Eater, Edger and Sweeper Combo, Includes 2 Batteries (LCC222)
Our pick — over 4★ from 12,500+ verified ratings; the strongest balance of quality and price.
A sub-11-pound combo with an edger wheel for precise borders.
BLACK+DECKER designed this set for ultra-light yard work. The trimmer weighs 4.5 pounds and converts into a wheeled edger by flipping the head and dropping the guide wheel onto the pavement — no tools needed. The blower weighs just 3.7 pounds and runs quiet enough that neighbors will not complain.
The AFS (Automatic Feed Spool) system feeds trimmer line as needed, so you never bump the head to advance it. The kit includes two 1.5Ah batteries that hold their charge for up to 18 months in storage, which is handy for seasonal use. Customers note the batteries last 20 to 30 minutes each, enough for a small yard but tight for anything larger. The charger is slow, taking a few hours to refill a depleted battery.
The main limitation is power. The blower is weak — reviewers point out it will not move wet grass or heavy debris, and it is fine only for dry leaves on a garage floor. At 10.5 pounds total, the kit is the lightest on this list, and the common 20V battery platform works with other BLACK+DECKER tools. For a townhouse patio or a small city lot, this combo gets the job done at the lowest cost.
What Makes It Easy
- Trimmer converts to a wheeled edger for clean borders instantly
- Only 10.5 pounds total; easy for anyone to handle and carry
- AFS auto-feed line works without bumping the head
What Holds It Back
- Blower lacks power to move wet leaves or heavy debris
- 1.5Ah batteries last only 20-30 minutes and charge slowly
Best for small city lots and basic touch-ups: If you have a tiny yard or just need to trim edges and sweep a patio, this ultra-light combo is the most affordable way in.
Not for anyone with a medium or large yard: The weak blower and short battery life mean this set is best left for the smallest properties or light seasonal use.
2. Greenworks 60V Cordless Yard Tool Combo Kit
A 60V powerhouse that blows and trims without needing a second battery.
You get enough muscle for a medium-to-large yard from this combo. The trimmer cuts a 13-inch path with a dual-line bump feed system that uses 0.080-inch string, so it chews through tough weeds around fences without stopping. The blower moves 540 CFM of air at up to 140 MPH with a turbo button that kicks the power even higher for wet leaves on a driveway.
The single 4.0Ah battery is the real story here. Buyers report it runs for about 40 minutes with the battery bar still showing charge left, which is enough for most yards. The catch is weight — at 22 pounds total, the trimmer is hefty. Owners mention that a shoulder strap would help for extended use, and the lack of one means your arms feel the fatigue sooner.
Greenworks backs this set with a 4-year limited warranty on both the tools and the battery, which adds confidence that cheaper combos do not offer. If you have a quarter-acre or more and want one battery to handle both jobs, this is the best-balanced package on the list.
Why It Leads
- 540 CFM blower with turbo mode clears heavy debris fast
- 60V 4.0Ah battery delivers long runtime per charge
- 4-year warranty covers both tools and battery
The Trade-offs
- Trimmer is heavy at 22 pounds with no included shoulder strap
- Only one battery included; a spare would help for larger properties
Best for medium-to-large yards: If you have a quarter acre or more and want a single battery to handle trimming and blowing, this is the combo to beat.
Watch out for weight fatigue: Buyers suggest buying a third-party shoulder strap for the trimmer if you plan to use it for more than 20 minutes at a time.
3. Makita XT287SM1 18V LXT Brushless 2-Pc. Combo Kit
Top-shelf build quality with a blower that pushes 459 CFM in a balanced package.
Makita’s reputation for pro-grade tools shows in this kit. The blower uses a brushless motor to deliver 459 CFM and 116 MPH, with a cruise control lever on the variable-speed trigger that lets you lock a speed and focus on aiming the nozzle. The trimmer spins at up to 6,000 RPM with a high/low button so you can save battery on light grass and punch through thick weeds when you need to.
The runtime is solid — one reviewer ran the trimmer on low for 30 minutes and used only half the charge on the 4.0Ah battery. Buyers who switched from Black & Decker say this kit is noticeably more powerful and lighter. The catch is the trimmer head does not rotate for edging, which makes border work a bit awkward compared to combos that flip with a button.
At this price, you get the 3-year limited warranty on tool, battery, and charger. If you already own other Makita 18V tools, this combo makes even more sense because the batteries work across everything.
What Stands Out
- Blower cruise control locks your preferred airspeed
- Trimmer delivers up to 6,000 RPM with power management modes
- Runs on Makita’s 18V LXT platform with hundreds of compatible tools
What to Know
- Trimmer head does not rotate for edging
- Comes with one battery; a second is recommended for larger yards
Ideal for pro DIYers: If you are already in the Makita 18V ecosystem or want the best build quality in a cordless combo, this kit justifies the premium.
One battery is tight: Buyers recommend picking up a second battery if your yard takes more than 30 minutes of trimming plus blowing.
4. EGO POWER+ ST6703LB Combo, 15″ Trimmer and 670 CFM Blower
The 670 CFM blower is the strongest on this list, and the 15-inch trimmer chews through weeds.
EGO built this combo for people who want to clear a big property fast. The blower hits 670 CFM and 180 MPH with the tapered nozzle, more than any other combo here, and the variable-speed dial ranges from 250 to 530 CFM plus a turbo boost for stuck debris. The trimmer cuts a 15-inch path — the widest on the list — using a professional-grade dual-line spiral twist that uses 0.095-inch string. The POWERLOAD system lets you feed new line at the push of a button, which is much faster than threading the head by hand.
The 56V 4.0Ah battery is EGO’s ARC Lithium series. Customers note the battery lasts about 80 minutes of mixed use, which is impressive given the power. The trimmer and blower have IPX4-rated weather-resistant construction, so light rain will not stop you. The main trade-off is weight — this kit is 21.76 pounds, and the trimmer is sturdy but heavy. Reviewers point out the trimmer needs a shoulder strap for careful work around garden edges.
EGO backs the tool with a 5-year limited warranty and the battery with a 3-year limited warranty. If you want the most clearing power available in a cordless combo and have the budget, this is it.
Where It Excels
- 670 CFM / 180 MPH blower clears wet leaves and heavy debris easily
- 15-inch cutting swath with 0.095-inch dual-line spiral twist
- POWERLOAD button loads trimmer line in seconds
Where It Struggles
- Trimmer is heavy and needs a shoulder strap for comfort
- Blower drains the single battery fast; a second battery would help
Best for heavy-duty clearing: If you have thick weeds, wet leaves, or a large yard, this combo delivers more power than anything else on the list.
Plan for extra batteries: The blower eats battery quickly on turbo, so homeowners with an acre or more will want a spare 56V battery.
5. Dewalt String Trimmer-BLWR CRDLSS 20V DCKO215M1
A trusty combo that taps into the vast Dewalt 20V ecosystem.
If you already have Dewalt power tools, this kit is an easy add. The trimmer uses the DCST925 model, which shoppers say is light and easy to use with impressive power that competes well with gas trimmers. The blower is the DCBL722, which reviewers describe as powerful but a battery hog — it will drain the included 4.0Ah battery quickly if you run it on high speed.
The 13-inch cutting width is standard for the category, and buyers report the trimmer runs for about an hour on a single charge for light trimming. The blower is lighter than expected, which makes it easy to handle for short cleanup jobs around the driveway and deck. The trade-off, as multiple owners mention, is that the included 4.0Ah battery is undersized for the blower’s appetite. Plan to use a larger 5.0Ah or 6.0Ah battery from your existing Dewalt collection if you have one.
The kit includes just one battery, which is a limitation for the blower. If you are not already in the Dewalt 20V system, you will want a spare battery, which adds to the overall cost.
Why It Wins
- Trimmer is lightweight and easy to use for extended sessions
- Shares batteries with the entire Dewalt 20V tool lineup
- Blower is compact and lighter than expected
Why It Falls Short
- Included 4.0Ah battery is underpowered for the blower
- Only one battery included; a second is necessary for full-yard use
Great for Dewalt owners: If you already have a collection of Dewalt 20V batteries, this combo is a smart and cost-effective addition to your outdoor gear.
Not a standalone deal: Anyone new to Dewalt should factor in the cost of a second battery, because the blower needs more capacity than the included one provides.
6. CRAFTSMAN 20V MAX WEEDWACKER String Trimmer and Leaf Blower Combo Kit (CMCK197M1)
A telescoping pole makes turning the trimmer into an edger easy.
This combo from Craftsman focuses on user-friendly design. The CMCST900 trimmer has a telescoping pole that extends and contracts so you can switch from trimming to edging without bending over or fussing with a separate attachment. The auto-advance line system feeds 0.065-inch line automatically as you work — no bumping required, which saves time when you are in a rhythm along a long fence line.
The CMCBL700 blower delivers up to 340 CFM at 90 MPH. Customers note it is lightweight and very quiet, easy for anyone in the household to use. The 4.0Ah battery provides enough runtime for about 45 minutes of mixed use, which covers most small to medium yards. Reviewers mention the battery life is excellent for the trimmer, but the blower will drain it faster.
If you have an acre or heavy overgrowth, this combo will struggle. The blower does not compare to a gas unit for velocity, and the auto-feed line can jam in very thick weeds. For a standard suburban lot with regular maintenance, the ease of use here is tough to top.
Ease of Use Highlights
- Telescoping pole converts trimmer to edger quickly without tools
- Auto-advance line feeds without bumping the head
- Blower is lightweight and quiet enough for any family member to handle
Areas to Improve
- Blower is underpowered for wet or heavy debris on a large property
- One battery is included; a second pack is needed for bigger yards
Perfect for suburban lots: If you have a small to medium yard with regular light maintenance, this combo’s easy edging and simple line feed make yard work much less of a chore.
Not for heavy-duty work: Homeowners with over an acre or thick overgrowth will find the blower and auto-feed system underpowered for their needs.
7. SKIL CB7542B-10 PWR CORE 20 Brushless 13″ String Trimmer and 400 CFM Leaf Blower Kit
A lightweight, brushless pair with a Twist Load head that reloads in seconds.
SKIL’s PWR CORE 20 technology wraps each battery cell with cooling material, which the company says delivers 25% longer run time and double the battery life compared to standard packs. The brushless motor on both tools gives you efficient power without the hassle of gas. The trimmer cuts a 13-inch path and uses a patented Twist Load head — you insert the 0.080-inch line and twist to load it, which is much easier than traditional threading.
The blower pushes 400 CFM, enough to clear clippings and light leaves from a driveway quickly. The trimmer is light at 14.11 pounds for the whole kit, making it easy to maneuver one-handed. The catch, and it is a common one here, is battery life. One reviewer notes that the 2Ah battery lasts a maximum of 20 minutes and charges in about the same time, so you end up playing a swap-and-wait game unless you buy a spare.
The included 4.0Ah battery helps — reviewers point out it is enough for a full trim and driveway blow on a standard lot. The kit also comes with Easy Storage Brackets for wall mounting. SKIL offers a 5-year warranty on the tool and 2 years on the battery if you register within 30 days.
Smart Features
- Twist Load head makes line replacement fast and frustration-free
- Brushless motor on both tools improves efficiency and lifespan
- PWR CORE 20 battery technology extends runtime and battery longevity
Mind the Limits
- Standard 2Ah battery lasts only 20 minutes under load
- Not powerful enough for overgrown or neglected yards
Smart buy for regular maintenance: If you keep up with your yard and want a lightweight, brushless combo with a headache-free line-loading system, the SKIL delivers excellent value.
Skip it for heavy growth: Shoppers say this combo is fine for regular upkeep but will struggle with thick weeds or very large properties without a spare battery.
8. KIMO 20V Weed Wacker and Blower Combo w/2 x 2.0Ah Battery & Charger
Two batteries and a wheeled guide for easy edging at a budget price.
KIMO packs an impressive amount of gear into this set. The trimmer uses a brushless motor that spins at 20,000 RPM with a 12-inch cutting width, and the blower delivers 260 CFM at 190 MPH. What makes this combo stand out at the lower price point is the wheeled guide that clips onto the trimmer for edging — it glides along the sidewalk border so you get a straight line without straining your back.
The kit includes two 2.0Ah batteries, giving you double the runtime compared to combos with a single battery. Buyers report the whole setup is lightweight, so it is easy to handle in tight spots around flower beds and fences. The auto-feed line system works well, and the kit throws in four replacement spools and six plastic cutting blades, enough for a full season of regular trimming.
The trade-off is power. The 20V system cannot match higher-voltage combos for heavy weeds or wet debris. Owners mention the lower handle feels a bit flimsy and needs occasional adjustment. For quick touch-ups and a small yard, this is a phenomenal value.
What You Get
- Two 2.0Ah batteries provide extended runtime for the price
- Wheeled guide makes edging along sidewalks precise and easy
- Includes four spare spools and six blades for a full season
Where It Cuts Corners
- 20V platform lacks power for thick weeds or wet debris
- Lower handle feels less sturdy and requires frequent adjustments
Ideal for small yards and quick touch-ups: If your lot is compact and you want a lightweight, easy-to-use combo with plenty of spares included, this budget pick is a steal.
Not for heavy-duty or large properties: The lower power and flimsier build mean this combo is best reserved for light, regular maintenance rather than overgrown lots.
Understanding the Specs
Battery Voltage and Amp-Hours (Ah)
Voltage (V) tells you the tool’s potential power — higher voltage usually means more torque for cutting thick weeds and more airspeed for blowing. Amp-hours (Ah) tell you the battery’s fuel tank size. A 4.0Ah battery holds more energy than a 2.0Ah one, so it runs the same tool longer. A combo with two smaller batteries can give you the same total runtime as one big battery, but you have to swap them mid-job.
CFM and MPH in Blowers
CFM (cubic feet per minute) measures the volume of air the blower moves — high CFM clears a wide pile of leaves fast. MPH (miles per hour) measures the speed of that air, which matters for dislodging stuck debris from a lawn or driveway. A blower with 400 CFM at 100 MPH moves a large volume of air at moderate speed, while a 260 CFM at 190 MPH blows harder on a narrower stream. For clearing a whole lawn, go for higher CFM. For blasting a patch of wet leaves, higher MPH wins.
