Description

Overview of the Kobalt KHB 3040-06

The Kobalt KHB 3040-06 in use

The Kobalt KHB 3040-06

  • Power: The Kobalt KHB 3040-06 is a cordless blower with a maximum air volume rating of 480 CFM and an air speed of 110 MPH.
  • Power delivery: Kobalt engineered this battery-operated blower with mobility as a top priority, ensuring users can effortlessly navigate their outdoor space without the constraints of cords.
  • Battery: Its 3 Ah 40 V Li-ion battery (1 battery included) enables the blower to run for up to 20 minutes without needing to recharge.
  • Handling: Ideal for those seeking a compact and portable leaf blower, this model provides ease of handling and use, making it a convenient choice for any task. At 7.5 lbs (battery included), the Kobalt KHB 3040-06 is positioned within the average weight range for cordless handheld blowers, offering a balanced weight profile compared to others in its category.
  • Speed Settings: There are times when you only need a little more power, while other times you will want a bit more precision when clearing leaves and debris.

The Kobalt KHB 3040-06's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Kobalt KHB 3040-06 compare with handheld leaf blowers of similar voltage (between 36 and 48V).

  • Air expelled from the nozzle of this blower can reach 110 MPH. When compared to others of this type, the KHB 3040-06 has a lower air speed than most battery-operated handheld blowers in the 36 and 48V range. For the fastest air speed in this category, you may want to consider the Makita XBU01PT, which can expell air at a velocity that can reach 208 MPH.
  • The Kobalt KHB 3040-06 boasts an airflow rate of 480 CFM (cubic feet per minute), which is standard for cordless handheld blowers. If air volume is important to you, the Husqvarna 350iB, with 800 CFM, could be in your good books.
  • Users can expect a maximum autonomy of 20 minutes from its battery, which means the KHB 3040-06 won't run as long as many other cordless handheld units before needing to be plugged in. To enjoy the best possible autonomy in this category, you could have a look at the Makita CBU01Z which offers up to 300 minutes of runtime.

Price comparison

As you can see from these interactive charts, when compared to other cordless blowers, the Kobalt KHB 3040-06 is on the cheap side of the price range.

    Replacement parts are hard to locate on my Kobalt leaf blower. The battery clip broke on my Kobalt leaf blower model# 3040-60. Where do I go to obtain a replacement battery clip holder?

    + PROS: Good price and battery life is acceptable during a normal work day around the home yard.
    - CONS: Replacement parts appears to be very limited.
