Description
Zoom on the Kobalt KHB 4224A-03
The Kobalt KHB 4224A-03
With its cordless handheld design, the Kobalt KHB 4224A-03 is a good match for homeowners with an average-sized yard that requires regular upkeep, generally around a quarter to half an acre.
It provides a maximum air volume rating of 500 cubic feet per minute (CFM) and an air speed of up to 120 miles per hour (MPH). For the user, this translates to modest airflow, moving dry leaves and small debris around a yard, patio, or driveway.
Equipped with a 24V brushless motor, the unit operates on battery power for untethered use. It is supplied with a 4.0Ah battery which can offer up to 50 minutes of runtime per charge.
With its adjustable airflow through variable speed settings and a turbo button, the Kobalt KHB 4224A-03 puts control in the hands of the user, allowing for tailored performance.
With a bare tool weight of 3.7 lbs and 5.4 lbs when fully equipped, this handheld unit supports one-handed use in tight areas.

The Kobalt KHB 4224A-03's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Kobalt KHB 4224A-03 compare with handheld leaf blowers of similar voltage (between 18 and 24V).
- With a bare tool weight of 3.7 lbs, the Kobalt KHB 4224A-03 sits at the lower end of the scale for cordless handheld blowers in the 18 to 24V range. Should weight be a deciding factor, the Worx WG543 is worth a look at just 2.3 lbs the bare tool.
- Forced air exiting this blower has been clocked at a maximum speed of 120 MPH, positioning the KHB 4224A-03 at the forefront in terms of air velocity among battery-operated handheld blowers between 18 and 24V. If you wish to benefit from air expelled at the fastest possible speed, the Makita XBU07SM1 and its 143 MPH could be an option to consider.
- The KHB 4224A-03 is powerful, with an airflow rating of 500 CFM (cubic feet per minute). This is certainly on the high end compared to other cordless handheld blowers with a comparable voltage. If air volume is important to you, the Dewalt DCBL724W1, with 550 CFM, could be in your good books.
- Thanks to its autonomy of up to 50 mins, the KHB 4224A-03 benefits from a higher run time than many cordless handheld units in the aforementioned voltage range. If autonomy is an important factor for you, the Ryobi PBLLB01K can run for up to 60 minutes and could be worth considering.
- Because larger batteries naturally increase runtime, it can be helpful to consider runtime efficiency, a measure of how effectively a blower uses the energy available. The Kobalt KHB 4224A-03 delivers a typical level of runtime efficiency, offering a balanced amount of operation time per unit of battery capacity. If runtime efficiency matters most to you, you might look at the Ryobi ONE+ SWEEPER P2102, which delivers a higher runtime efficiency of 1.28 minutes per Wh.
Price comparison
As you can see from these interactive charts, when compared to other 18-24V cordless blowers, the Kobalt KHB 4224A-03 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget blower.
