CORVELLAN 4 Speed Cordless Leaf Blower 670 CFM 180 MPH with Battery & Charger

The CORVELLAN cordless leaf blower delivers up to 670 CFM of airflow and 180 MPH air speed, powered by a 45,000 RPM brushless motor.

It is designed for everyday residential cleanup, including dry leaves, grass clippings, dust, small twigs, and other light yard debris on lawns, driveways, sidewalks, patios, decks, and around landscaping.

They measure two different parts of blower performance:

• CFM (Cubic Feet per Minute) measures how much air the blower moves. Higher CFM helps move larger amounts of leaves and debris at once.
• MPH (Miles per Hour) measures how fast the air leaves the nozzle. Higher MPH helps loosen heavier or more stubborn debris.

Neither number tells the whole story by itself. The CORVELLAN blower combines up to 670 CFM with 180 MPH, giving you both high air volume and concentrated air speed.

The 4-speed design lets you choose between longer runtime and stronger airflow depending on the job:

• Speed 1 — 350 CFM: Light leaves, dust, and quick cleanup
• Speed 2 — 450 CFM: Sidewalks, patios, decks, and regular yard cleanup
• Speed 3 — 550 CFM: Larger leaf piles and heavier cleanup
• Sports Mode — 670 CFM: Maximum airflow for stubborn or heavier debris

You don't need maximum power for every job. Using a lower setting when possible can significantly extend your working time.

Yes, it can help move lightly damp leaves, especially at Speed 3 or in Sports Mode.

However, completely soaked or matted leaves naturally require more effort than dry leaves. For wet leaves, keep the nozzle closer to the ground and work from the outside edge of the pile instead of trying to move the entire pile at once.

For the easiest cleanup and longest battery runtime, we recommend using the blower when leaves are relatively dry whenever possible.

Runtime depends heavily on the speed setting you use. With a fully charged battery, approximate runtime is:

• Speed 1 / 350 CFM: Up to 40 minutes
• Speed 2 / 450 CFM: Up to 30 minutes
• Speed 3 / 550 CFM: Up to 25 minutes
• Sports Mode / 670 CFM: Up to 15 minutes

Actual runtime may vary depending on temperature, battery condition, debris type, and how continuously the blower is operated.

Sports Mode pushes the motor to its highest output to produce up to 670 CFM of airflow. Higher motor output naturally requires more battery power.

For most jobs, we recommend using Speed 1–3 for general cleanup and switching to Sports Mode when you encounter heavier leaf piles or stubborn debris.

This gives you maximum power when you need it without using it for the entire job.

The blower is designed primarily for residential yards, driveways, sidewalks, patios, decks, and landscaping areas.

For small and medium-sized yards, one battery may be enough for typical cleanup depending on the amount of debris and speed setting used.

For larger properties or heavy fall cleanup, an additional charged battery can be helpful, especially if you plan to use Sports Mode frequently.

The blower comes with a 21V 6000mAh lithium-ion battery.

The high-capacity rechargeable battery provides cordless operation, so there is no extension cord, gasoline, or fuel mixing required.

For best battery life, allow the battery to cool after heavy use before charging and avoid storing it completely discharged for extended periods.

Yes. Everything needed for normal operation is included.

The package includes:

• CORVELLAN cordless leaf blower
• 21V 6000mAh lithium-ion battery
• Fast charger
• Shoulder strap

You do not need to purchase the battery or charger separately to start using the blower.

Do not assume that every battery labeled 21V is automatically compatible.

Battery connections, current output, and internal design can differ between tools even when the listed voltage is the same.

If you already own another CORVELLAN product and would like to use its battery with this blower, please contact CORVELLAN customer support to confirm compatibility first.

The cordless design eliminates the need to drag an extension cord or handle a gas-powered engine during normal yard cleanup.

A shoulder strap is included to help distribute the load during longer sessions.

For larger jobs, we also recommend alternating between lower and higher speed settings instead of continuously operating in Sports Mode. This can make the blower easier to control while extending battery runtime.

The blower can be useful throughout the year, not just during fall.

Common uses include:

• Clearing grass clippings after mowing or trimming
• Blowing leaves from lawns
• Cleaning sidewalks and driveways
• Clearing patios and decks
• Removing loose dirt and light debris
• Cleaning around fences and landscaping
• Gathering scattered leaves into piles
• Clearing light debris after yard work
• Blowing water from hard-to-reach exterior areas after washing a vehicle

Always check the area for loose stones or other objects before using high-speed airflow.

Some warmth during use is normal for a lithium-ion battery, particularly during extended use or when operating at higher power settings.

If the battery becomes unusually hot, stop using the blower and allow the battery to cool naturally before charging or using it again.

For better long-term battery health, avoid immediately charging a very hot battery after extended Sports Mode use.

First turn the blower off and check a few basic things:

1. Make sure the battery is properly inserted.
2. Check whether the battery needs to be charged.
3. Allow the battery and motor to cool if the blower has been used continuously at high power.
4. Inspect the air intake for leaves or other debris.
5. Check the blower tube for any visible blockage.

After checking these items, reinstall the battery and try again.

If the blower still does not operate normally, stop using it and contact CORVELLAN customer support for assistance.

Basic maintenance can help keep your blower and battery working properly.

After use:

• Turn the blower off and remove the battery.
• Clear leaves and debris from the air intake.
• Wipe dirt from the blower housing and tube.
• Keep the blower and battery in a cool, dry indoor location.
• Keep the battery away from excessive heat, moisture, and direct sunlight.
• Do not store the battery completely discharged for long periods.
• Allow a warm battery to cool before charging.

For seasonal storage, remove the battery from the blower and store the tool and battery separately in a dry indoor location.
