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).

  • It can push air from the nozzle at 120 MPH, which puts it ahead of its class in terms of air speed for 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.
  • If air volume is an important feature, the KHB 4224A-03 by Kobalt will not disappoint. Its airflow maxes out at 500 CFM (cubic feet per minute), which is more powerful than most cordless handheld blowers with a comparable voltage. If air volume is important to you, the Ryobi PBLLB01K, with 510 CFM, could be in your good books.
  • The longevity of this model’s battery is notably higher than most cordless handheld units. It offers an autonomy of up to 50 minutes. If autonomy is an important factor for you, the Ryobi PBLLB01K can run for up to 60 minutes and could be worth considering.
