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.
- The KHB 400B is average in terms of air volume. It's rated at 500 CFM, which is common for cordless handheld blowers. If air volume is important to you, the Husqvarna 350iB, with 800 CFM, could be in your good books.
- Its battery is standard in terms of autonomy for a cordless handheld product. Fully charged, it should run for up to 70 minutes. If autonomy is an important factor for you, the Makita CBU01Z can run for up to 300 minutes and could be worth considering.
