The Black+Decker LSW321BT's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Black+Decker LSW321BT compare with similar leaf blowers.

  • The Black+Decker LSW321BT expels air at speeds up to 130 MPH, making it standard 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).
  • It’s capable of expelling a maximum air volume of 80 CFM (cubic feet per minute). This places it at the low end compared to other 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 LSW321BT 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).

Smartech™ Battery Technology

Black Decker Smarttech Banner

The Black+Decker LSW321BT uses a battery that features Smartech™ technology. Thanks to a companion app for Android and iOS, Smartech™ allows you to control the battery remotely: it’s possible to locate the unit (by telling it to emit an audible and visual alert) and lock the unit (in case of theft). You can even monitor its charge with the app. Moreover, Smartech™ batteries feature a built-in USB port, allowing you to use the battery to charge your phone or other devices.

POWERBOOST Technology

POWERBOOST is one of the features of the POWERCOMMAND™ line of Black+Decker outdoor power tools. The Black+Decker LSW321BT 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 LSW321BT enjoys a normal runtime, so this feature is definitely ideal for tackling less rigorous tasks with more precise control.
