Overview of the Black+Decker LSW321BT

The Black+Decker LSW321BT in use

The Black+Decker LSW321BT

  • Power: The Black+Decker LSW321BT can force 80 cubic feet of air per minute (CFM) from its nozzle at a maximum 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: Its 1.5 Ah 20 V Li-ion Smartech™ battery (1 battery included) means that a user can operate the LSW321BT for an estimated 25 minutes on a full charge. More info on the Smartech™ battery can be found below.
  • Handling: Being handheld, this blower has a good maneuverability and is meant to be easier to carry around over a small period of time. Among other cordless handheld blowers, the Black+Decker LSW321BT can be considered light, weighing only 3.7 lbs.
  • Speed Settings: This unit is a one-speed leaf blower.
  • Noise: With a decibel rating of 53 dB, the LSW321BT is neither louder nor quieter than its rivals in the electric handheld category.

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.

  • Upon exiting the nozzle, the air can reach speeds of up to 130 MPH, which is pretty much what is to be expected for battery-operated handheld blowers. If you wish to benefit from air expelled at the fastest possible speed, the Makita XBU01PT and its 208 MPH could be an option to consider.
  • 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. For the highest air volume, you may want to have a look at the Snapper XD PowerGrip, which boasts with 700 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. To enjoy the best possible autonomy in this category, you could have a look at the EGO POWER+ LBX6000 which offers 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 LSW321BT 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.

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.

  • Inexpensive
