The Kobalt KHB 350-06

The Kobalt KHB 350-06 is a cordless handheld blower that is appropriate for homeowners with yards that fall in the mid-size range, suitable for seasonal cleanup and routine care.

It is capable of expelling a maximum air volume of 350 cubic feet per minute (CFM). Its air speed is rated at 100 miles per hour (MPH). To put it simply, it handles a limited amount of leaves and debris on a small lawn or garden area, suitable for light, occasional clearing.

The KHB 350-06 is equipped with a 40V brushed motor and runs on battery power, enabling mobility without a cord. It comes with one 2.5Ah battery which can provide up to 30 minutes of runtime on a full charge.

To provide more control over their job to the user, the unit has a variable speed control setting. No matter the size of the job, the user can adjust the airflow of the Kobalt KHB 350-06 to match it. On top of that, maintaining the selected speed is effortless, as it also features cruise control.

This blower weighs 4.1 lbs as a bare tool and 6 lbs with the battery, this handheld blower makes one-handed operation straightforward.

The Kobalt KHB 350-06's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Kobalt KHB 350-06 compare with handheld leaf blowers of similar voltage (between 36 and 48V).

Important: All figures are based on published specifications. Because manufacturers may test at different power levels or under different conditions, use the autonomy/runtime efficiency figures as a guideline only.
  • Compared to its counterparts, the Kobalt KHB 350-06 offers a lighter bare tool option within the cordless handheld in the 36 to 48V range, at 4.1 lbs. Should weight be a deciding factor, the Black+Decker LSW40C is worth a look at just 2.4 lbs the bare tool.
  • Maxing out at 100 MPH, this blower ranks on the lower end in terms of air speed for battery-operated handheld blowers between 36 and 48V. For the fastest air speed in this category, you may want to consider the Husqvarna 350iB, which can expell air at a velocity that can reach 200 MPH.
  • As this unit is rated at 350 CFM (cubic feet per minute), it expells less air than most cordless handheld blowers with a comparable voltage. For the highest air volume, you may want to have a look at the Ryobi RY40HPLB01K, which boasts with 800 CFM.
  • When fully charged, the KHB 350-06 offers up to 30 minutes of autonomy, which may be considered relatively short compared to cordless handheld units of comparable voltage. To enjoy the best possible autonomy in this category, you could have a look at the Stihl BGA 200 which offers up to 535 minutes of runtime.
  • 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. At its measured figures, the Kobalt KHB 350-06 provides an average runtime efficiency, similar to many battery-powered handheld blowers. If runtime efficiency matters most to you, you might look at the Stihl BGA 50, which delivers a higher runtime efficiency of 0.8 minutes per Wh.
