The 7 best cordless leaf blowers, by what the battery can really do
Updated
Short version: for a normal suburban yard, I'd pick the EGO LB6151. It has 615 CFM on tap and a dial that lets you work at 200 to 480 CFM to stretch its 140 Wh battery. For a big yard or wet leaves, the EGO LB7654 has twice the battery, and EGO tells you its turbo time straight: 15 minutes. For patios and decks only, the WORX WG547 weighs 4.4 pounds with its battery.

Quick comparison
| Model | Max CFM | Max MPH | Battery in box | Wh in box | Runtime claim | Minutes at full power |
|---|---|---|---|---|---|---|
| EGO LB6151 | 615 | 170 | 56V 2.5Ah | 140 | Up to 75 min, setting not stated | About 9 to 15 min (our estimate) |
| EGO LB7654 | 765 | 200 | 56V 5.0Ah | 280 | Up to 90 min, an average. Maker page adds 15 on turbo and 150 on low | 15 min (maker) |
| Greenworks 40V 550 | 550 | 130 | 40V 4.0Ah | 160 | Up to 20 min, on high, per the maker page | 20 min (maker) |
| Greenworks 80V 700 | 700 | 170 | 80V 2.5Ah | 200 | Up to 60 min, maker page, setting not stated | About 11 to 19 min (our estimate) |
| WORX WG547 | 360 | 75 | 20V 2.0Ah | 40 | No runtime figure seen | About 4 to 7 min (our estimate) |
| BLACK+DECKER LSW221 | 100 | 130 | 20V 1.5Ah | 30 | No runtime figure seen | Not estimated |
| Makita XBU03Z | 459 | 116 | None (bare tool) | 0 | Bare tool, no battery in the box | About 8 to 13 min with an 18V 5.0Ah pack (our estimate) |
"Wh in box" is label volts times amp-hours. EGO's battery page prints the same math: its 56V 2.5Ah pack is 140 Wh and its 5.0Ah pack is 280 Wh. The WORX listing shows 40 watt-hours for its 20V 2.0Ah pack.
"Our estimate" means this: the two full-power runtimes the makers publish work out to 0.87 watts per CFM (Greenworks 40V) and 1.46 watts per CFM (EGO LB7654). We round that to a band of 0.9 to 1.5 watts per CFM and apply it to each blower's top CFM. It is a rough planning figure, not a measurement.

The picks
Specs and owner feedback checked on Amazon September 19, 2026. Runtime claims come from each listing or the maker's own page, as noted.
EGO POWER+ LB6151 615 CFM Kit (2.5Ah)
Get this if you have a normal suburban lot, a driveway and some lawn, and you want real airflow without a heavy tool. Skip it if you expect to run turbo the whole time. The kit battery is 140 Wh, and the 75 minute claim does not say which setting it is for. At full power we estimate about 9 to 15 minutes. The dial runs from 200 to 480 CFM, and that is where most of your work will happen.
Key specs (from the manufacturer listing)
- Turbo: up to 615 CFM and 170 MPH with the tapered nozzle. Dial: 200 to 480 CFM
- 56V 2.5Ah battery (140 Wh) and standard charger in the box
- Maker claims up to 75 minutes. Setting not stated
- Full power: about 9 to 15 minutes (our estimate)
- Listing shows 71 dB. EGO's own page says 63 dB
- 7.5 pounds listed. 5-year tool warranty per the listing
Recurring themes in owner feedback
- They like: Owners call it strong enough to clear sidewalks and like the quiet running and the speed dial.
- They complain about: Battery life gets mixed feedback. Some report 40 to 45 minutes at normal output, others say the pack runs out far too soon. Weight and long-term durability also get mixed reports.
Good
- Wide dial range so you can save the battery
- Pack charges in 50 minutes per the listing
- Battery fits all EGO 56V tools
Watch out for
- Smallest EGO battery, so turbo time is short
- Runtime claim does not name a setting
- Owners are split on battery life
EGO POWER+ LB7654 765 CFM Kit (5.0Ah)
Get this if you have a big yard, lots of trees, or wet leaves to move, and you want the largest battery on this page. Skip it if weight matters more than power. It is 9.5 pounds on the listing. EGO is the one maker here that prints both ends of the truth: 15 minutes on turbo, 150 minutes on low, from the same 280 Wh pack. That works out to about 1,120 watts on turbo and about 112 on low.
Key specs (from the manufacturer listing)
- Turbo: up to 765 CFM and 200 MPH with the tapered nozzle. Dial: 260 to 580 CFM
- 56V 5.0Ah battery (280 Wh) and 320W charger in the box
- Maker: up to 90 minutes average, 15 on turbo, 150 on low
- Pack charges in 70 minutes with the included charger per the listing
- 64 dB on the listing
- 9.5 pounds listed. Tapered and spread nozzles. 5-year tool warranty
Recurring themes in owner feedback
- They like: Owners praise the power and say the controls are easy to use and comfortable in the hand.
- They complain about: Battery life gets mixed feedback, with some saying the charge does not last long. Some owners report early failures, and some find it a little heavy.
Good
- Most battery energy of any kit here
- Maker states the turbo runtime in plain words
- Two nozzles in the box
Watch out for
- Heaviest kit here
- Turbo empties the pack in 15 minutes
- Some owners report early failures
Greenworks 40V 550 CFM Kit (4.0Ah)
Get this if you want a light blower with mid-class airflow and a runtime number you can plan around. Greenworks says up to 20 minutes on high with the 4.0Ah pack. That is a full-power number, not a low-speed one. Skip it if you need to work longer than that in one go, since the maker page lists a 120 minute recharge.
Key specs (from the manufacturer listing)
- Up to 550 CFM and 130 MPH. Variable trigger, cruise control and a turbo button
- 40V 4.0Ah battery (160 Wh) and charger in the box
- Maker: up to 20 minutes on high, which is about 480 watts
- Recharge time 120 minutes per the maker page
- 78 dB on the listing
- 5.07 pounds listed. Model BLF442
Recurring themes in owner feedback
- They like: Owners say it clears grass clippings, sidewalks and driveways well and like the variable speed trigger. One owner reports about 34 minutes of runtime.
- They complain about: The review summary we read was mostly positive. The main tradeoff is weight, which gets mixed feedback. Some call it fine, others a little heavy.
Good
- Runtime is stated for high, not low
- Light for its airflow
- Battery works across the Greenworks 40V line
Watch out for
- Slow charger
- Loudest dB figure on this page
- MPH is lower than the EGO picks
Greenworks 80V 700 CFM Kit (2.5Ah)
Get this if you already own Greenworks 80V tools or want 700 CFM and a fast charger. Skip it if you are counting on the 60 minute runtime on the maker page. The page does not say what setting that is, and the pack holds 200 Wh. At full power we estimate about 11 to 19 minutes. Owners in the review summary report 20 to 30 minutes in normal use.
Key specs (from the manufacturer listing)
- Up to 700 CFM and 170 MPH in turbo
- 80V 2.5Ah battery (200 Wh) and charger in the box
- Maker page: runtime 60 minutes, setting not stated. The Amazon listing gives no runtime
- Full power: about 11 to 19 minutes (our estimate)
- Recharge in 40 minutes per the maker page. 74 dB on the listing
- 5.84 pounds on the listing. The maker page lists 16.7 pounds, which looks like a boxed weight
Recurring themes in owner feedback
- They like: Owners call it powerful, with some comparing it to a gas blower, and say the battery recharges quickly.
- They complain about: Some owners report only 20 to 30 minutes per charge. Opinions on noise are split, some find it slightly heavy, and some report failures after about a year.
Good
- Second highest CFM here
- Fast recharge
- Variable speed and cruise control
Watch out for
- Runtime claim names no setting
- Weight figures disagree between listing and maker page
- Some owners report failures after about a year
WORX WG547 20V Turbine Blower Kit (2.0Ah)
Get this if your job is a patio, deck, garage or short driveway, and you want something that weighs 4.4 pounds with the battery. Skip it for a lawn full of leaves. The listing itself shows 40 watt-hours. At full power we estimate about 4 to 7 minutes, and several owners report about 5.
Key specs (from the manufacturer listing)
- Up to 360 CFM. The listing shows 75 MPH
- 20V 2.0Ah battery (40 Wh, as the listing states) and charger in the box
- Two speeds. No runtime figure on the listing we read
- Full power: about 4 to 7 minutes (our estimate)
- 55 dB on the listing
- 4.4 pounds with battery per the maker
Recurring themes in owner feedback
- They like: Owners say it handles small and medium jobs and makes quick cleanup easy.
- They complain about: Battery life gets mixed feedback, with several owners reporting only about 5 minutes per charge. Some say it does not blow hard enough for their yard.
Good
- Very light
- Lowest dB figure on this page
- Battery fits other WORX 20V tools
Watch out for
- Small battery
- Low air speed, so wet or matted leaves will stay put
- Owners are split on power
BLACK+DECKER LSW221 20V MAX Sweeper (1.5Ah)
Get this if you only sweep hard surfaces like a porch, garage floor or short walk, and want the lightest tool here at 3.7 pounds. Skip it for any lawn work. Look at the two numbers on the listing: 130 MPH but only 100 CFM. That is fast air through a small tube. It scoots debris along concrete. It does not move a pile.
Key specs (from the manufacturer listing)
- Up to 130 MPH and 100 CFM
- 20V MAX 1.5Ah battery (30 Wh) and charger in the box
- No runtime figure on the listing we read
- Full power minutes: not estimated. Our airflow rule does not fit a small high-speed sweeper
- 61 dB on the listing
- 3.7 pounds. 2-year limited warranty per the listing
Recurring themes in owner feedback
- They like: Owners call it light and easy to use, and say it does well on patios, garages and other small jobs. Several say it is easier than a broom or rake.
- They complain about: Battery life gets mixed feedback. Some owners say the pack drains too fast.
Good
- Lightest pick here
- Battery fits other BLACK+DECKER 20V MAX tools
- Simple, one job, done
Watch out for
- Lowest CFM here by far
- Smallest battery here
- Some owners say the pack drains fast
Makita XBU03Z 18V LXT Brushless Blower (Bare Tool)
Get this only if you already own Makita 18V LXT batteries and a charger. Skip it if you do not. The listing says tool only, so the box has 0 Wh in it. With a common 18V 5.0Ah pack (90 Wh) we estimate about 8 to 13 minutes at full power. Some owners report about 10.
Key specs (from the manufacturer listing)
- Up to 459 CFM and 116 MPH
- Bare tool. No battery, no charger
- Variable speed trigger with a cruise control lever
- Full power: about 8 to 13 minutes on an 18V 5.0Ah pack (our estimate)
- 6.5 pounds with battery per the maker
- 3-year limited warranty per the listing
Recurring themes in owner feedback
- They like: Owners say it performs well on yard cleanup, has enough power for leaf piles, and runs quieter than other blowers they have used.
- They complain about: Battery life gets mixed feedback. Some owners report only about 10 minutes from a 5.0Ah pack. Durability reports are also split.
Good
- Uses batteries you may already own
- In-line fan for balance, per the maker
- Brushless motor
Watch out for
- Nothing to run it with in the box
- 18V packs hold less energy than the 56V and 80V kits
- Owners are split on battery life
Before you buy any battery blower
- Find the battery size in the box. Volts times amp-hours gives watt-hours. That is your fuel tank. "Bare tool" or "tool only" means the tank is not included.
- Ask what setting the runtime is for. If the listing does not say, assume it is the lowest one. Of these seven, only Greenworks (40V) and EGO (LB7654) publish a full-power runtime.
- Buy for CFM first. CFM moves piles. MPH is measured at a narrow nozzle and says less than it seems. See CFM vs MPH vs newtons.
- Check local rules. Some cities restrict gas blowers or set quiet hours for all blowers. See noise and gas blower rules. This is general information, not legal advice.
Before you pull the trigger
- Eyes. A blower throws grit and small stones. Wear safety glasses every time.
- Ears. Battery blowers are quieter than gas, but NIDCD says long or repeated sound at or above 85 dBA can cause hearing loss. For long sessions, wear ear plugs or muffs.
- People, pets, cars and windows. Keep them out of the line of fire. Never point the tube at anyone.
- Battery. Use the maker's charger. Stop using a pack that is swollen, cracked, or hot to the touch.
