At a maximum air volume of 630 CFM and an air speed of 140 MPH, the Kobalt 80V leaf blower might just be what you need to say goodbye to that gas blower as it is more than capable of blowing all kinds of debris and leaves from your lawn. With an air volume like this, you can easily move large piles of debris, twigs, wet leaves, or even snow and keep them moving without expelling too much energy, and you will get the ultimate result. 

On the other hand, the 140 MPH air speed might be disappointing and not move these objects fast enough, but that is a pretty standard speed for cordless handheld leaf blowers. For this reason, this blower is ideal for small, medium, to semi-large-sized homeowners and not for commercial purposes, because it will work at its utmost ability to cover the greater accomplishment.

If you think about it, the task would be a frustrating experience to carry a heavy blower around during long hours of yard cleanup, especially in the fall when there is bound to be a pool of leaves in your yard every hour. But the Kobalt 80V KHB 2580 06 weighs in at just nine pounds in total, and this is an aspect that one can give value to. 

Which means that, the weight and the all together are a relatively reasonable for such a great investment because you don’t have to carry around during lengthy cleanups. This lightweight feature is particularly beneficial for women and older users since the Kobalt 80V blower parts are well-balanced and the device can be easily maneuvered.

One of the most beneficial features of this cordless leaf blower is its speed control functions. The device is fitted with a speed control lever with three-speed settings that allows you to change the airspeed from low to medium to high quickly, and this is the turbo speed that the machine will work with its utmost ability. 

On the other hand, this is the type of machine that would also come with a helpful cruise control feature that you can use to maintain your desired speed for as long as you want, preventing your arms from wearing out due to holding down the throttle. In addition, you should also consider it, if you ever need an extra burst of power to move tough or heavy debris, you can easily utilize the turbo mode.

This device runs with a brushless motor which is now becoming increasingly popular among the latest leaf blower models. As a result of the latter, the motor is one that would be able to provide more torque and allows the blower to run longer. 

The air intake is located at the back of the blower, so it won’t suck in your clothes and lead to air loss during cleanups. Lastly, when you think about the Kobalt 80v battery, then you should think of it how it is also at the back of the blower and provides balance while working since the air nozzle in front is long.

How Has the Kobalt 80V KHB 2580 06 Evolved?

The Kobalt 80-volt max has evolved from the previous model the KHB 4024a 03 by having a three times faster running time from the other model, it is now 75 minutes, when it used to be 25 minutes. Showing how the company has invested time to fix the running time.

After a full charge, the battery delivers a 75-minute runtime on the low-power setting and up to 20 minutes on turbo. The turbo setting will use more of the battery because it is pushing the machine to an extended force.

Hence, the blower produces enough runtime for you to cover your whole yard and then some. To effectively optimize the runtime when using turbo mode, it is advisable only to use turbo mode to blow any heavy or tough debris and then switch back to normal speed immediately. Either way, you have nothing to worry about because the Kobalt KHB 2580-06 battery charges in under 40 minutes.

– Speed Settings

There are three speed settings on the variable-speed control feature that comes with the Kobalt blower, ranging from low, medium, and turbo. This feature is designed to easily adjust the air output to your desired speed, as some surfaces or debris might not require a full blast of air, and others will.

To begin with, the power, turbo, and speed control buttons are located on the blower’s handle, barely an inch away from your grip, so you can easily adjust the power output.
