  • Power: The Black+Decker LSW321BT is a cordless blower with a maximum air volume rating of 80 cubic feet per minute (CFM) and an air speed of 130 MPH.
  • Power delivery: As it is battery-operated, it doesn't need to be plugged in and therefore allows superb freedom of movement.
  • Battery: With its 1.5 Ah 20 V Li-ion Smartech™ battery, the Black+Decker LSW321BT has a standard, full-charge run time of up to 25 minutes. More info on the Smartech™ battery can be found below.
  • Handling: For those who are looking for a portable and convenient leaf blower, this model is a strong candidate. It’s designed for easy handling and use, and its size means it’s easily carried and stored. Among other cordless handheld blowers, the Black+Decker LSW321BT can be considered light, weighing only 3.7 lbs.
  • Speed Settings: The Black+Decker LSW321BT does not have multiple speed settings. Once the blower is turned on, it always operates at the same speed.
  • Noise: As far as electric handheld blowers go, this one is average in terms of noise with a rating of 53 dB.

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.

  • Forced air leaving this blower’s nozzle has been clocked at 130 MPH. That makes the LSW321BT 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 LSW321BT can reach 80 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).
  • Autonomy-wise, with up to 25 minutes of autonomy on a full charge, the LSW321BT is on the low end when compared with other cordless handheld units (the one with the best autonomy being the EGO POWER+ LBX6000 with up to 96 minutes of runtime).

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

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

Black Decker Powerboost banner

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.

The bottom line

  • Inexpensive
  • Lightweight (3.7 lbs)
  • Smartech™ Technology
  • POWERBOOST Technology
AVERAGE SPECS:
  • Acceptable noise (53 dB)
  • Decent MPH (130 MPH)
WEAKNESSES:
  • Brushed motor
  • No speed variation
