The Black+Decker LSW321's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Black+Decker LSW321 compare with similar leaf blowers.

  • Forced air leaving this blower’s nozzle has been clocked at 130 MPH. That makes the LSW321 average in terms of air speed for battery-operated handheld blowers (the one expelling air at the fastest speed being the Makita XBU01PT with 208 MPH).
  • Regarding its air volume, the airflow of the Black+Decker LSW321 can reach 100 CFM (Cubic Feet per Minute), which is on the low end for cordless handheld blowers (the biggest expelled air volume belonging to the Poulan Pro PRB675i with 675 CFM).
  • Users can expect an autonomy of 25 minutes from its battery, which means the LSW321 won't run as long as many other cordless handheld units before needing to be plugged in (the one with the best autonomy being the EGO POWER+ LBX6000 with up to 96 minutes of runtime).

Price comparison

As you can see from this interactive chart, when compared to other cordless blowers, the Black+Decker LSW321 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget blower.

POWERBOOST Technology

Black Decker Powerboost banner

POWERBOOST is one of the features of the POWERCOMMAND™ line of Black+Decker outdoor power tools. The Black+Decker LSW321 has a button that gives it a surge in blowing speed when pressed. Although POWERBOOST uses a lot of power (which drains the battery faster) , it is quite useful for loosening up those stubborn patches of debris that get stuck and otherwise refuse to budge. When POWERBOOST is used sparingly, the LSW321 enjoys a normal runtime, so this feature is definitely ideal for tackling less rigorous tasks with more precise control.

The bottom line

  • Inexpensive
