Iโve had my hands on a lot of lawn equipment. Overall, my experiences with Kobaltโs gear have been really positive. Indeed, I reviewed their 40V Max leaf blower (KLB 1040A-03) and was impressed with its performance and design. It was an excellent lightweight consumer-grade solution. This time, Iโm diving into the Kobalt 80V Max leaf blower (KHB 2580-06).
While I havenโt put this one to the test yet, the specs make this model a tool that I think warrants consideration. So, letโs see what it can do.
Kobalt 80V Max Leaf Blower Performance
Driving the 2580 is a high-efficiency brushless motor and Kobaltโs 80V Max 2.5Ah battery.
For a handheld unit, this blower is rather powerful. Specifically, weโre talking about blowing forces of up to 140 miles per hour and 630 CFM. Iโm a CFM guy, so I was pleased with this number.

Specs
- Model: Kobalt KHB 2580-06
- Battery: 80V (2.5Ah)
- Brushless motor
- Blowing force: 140 mph; 630 CFM
- Weight: 8.9 lbs
While Iโm curious how many Newtons this thing generates, velocity and volume tell a good portion of the Kobalt 80V Max leaf blowerโs story.
Although 140 mph isnโt bad at all, other handheld blowers surpass that by some 30 mph. Sure, it should remove wet debris, but you might have to make a few passes to effectively finish the job.
On the other hand, the 80V Max blowerโs 630 CFM rating is another matter; I think this is the 2580โs true selling point. This will provide ample volume. That means youโll be able to cover wide swaths of ground, allowing you to get more done in a shorter period.
That, combined with a 75-minute runtime, gives you a solid outdoor cleanup unit for roughly a quarter of an acre. (Thatโs Kobaltโs estimate. I think itโll do a little more, especially if you have a backup battery.)
Kobalt 80V Leaf Blower Design

When it comes to design, itโs the KHB 2580-06โs weight that stands out. Again, this was my favorite thing about its 40V relative, the 1040. I was thrilled with the feel and maneuverability of the latter. That said, the Kobalt 80V Max blower is roughly 4 pounds lighter, so I expect that these factors will be even better.
In my opinion, this will likely prove to be an ideal handheld tool, even for residential users with more challenging needs. If you push this unit to its 75-minute runtime limit, your arm likely wonโt be feeling it.
And there are still other mentionables with this model. For example, the variable speed trigger and cruise control dial will help make this tool more comfortable and easier to use. After all, itโs the little things that matter, as the old saying goes.
