Overview of the Kobalt KHB 400B
The Kobalt KHB 400B
- Power: The Kobalt KHB 400B can force 500 cubic feet of air per minute (CFM) from its nozzle at a maximum speed of 125 MPH.
- Power delivery: Kobalt designed this unit and its brushless, battery-operated motor with top-of-the-food-chain maneuverability in mind. The KHB 400B doesn’t need to be plugged in, so you can take it anywhere easily.
- Battery: Its 2 Ah 80 V Li-ion battery (battery not included) means that a user can operate the KHB 400B for an estimated 70 minutes on a full charge.
- Handling: For those who are looking for a portable and convenient leaf blower, this model is a strong candidate.

The Kobalt KHB 400B's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Kobalt KHB 400B compare with similar leaf blowers.
- Upon exiting the nozzle, the air can reach speeds of up to 125 MPH, which is pretty much what is to be expected for battery-operated handheld blowers. If you wish to benefit from air expelled at the fastest possible speed, the Makita XBU01PT and its 208 MPH could be an option to consider.
- If air volume is an important feature, the KHB 400B 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. If air volume is important to you, the Snapper XD PowerGrip, with 700 CFM, could be in your good books.
- Thanks to its autonomy of up to 70 mins, the KHB 400B benefits from a higher run time than many cordless handheld units. If autonomy is an important factor for you, the EGO POWER+ LBX6000 can run for up to 96 minutes and could be worth considering.
