The Kobalt KLB 1040A-03's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Kobalt KLB 1040A-03 compare with handheld leaf blowers of similar voltage (between 36 and 48V).
- The Kobalt KLB 1040A-03 tips the scales at just 4.8 lbs (bare tool), placing it among the more lightweight cordless handheld blowers in the 36 to 48V range. 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 120 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.
- The Kobalt KLB 1040A-03 boasts an airflow rate of 520 CFM (cubic feet per minute), which is standard for cordless handheld blowers with a comparable voltage. If air volume is important to you, the Ryobi RY40HPLB01K, with 800 CFM, could be in your good books.
