Overview of the Black+Decker LSW321BT

  • Power: The Black+Decker LSW321BT is blower with a maximum air volume rating of 80 cubic feet per minute (CFM) and an air speed of 130 MPH.
  • Power delivery: The LSW321BT is a battery-operated unit, so it doesn’t need to be plugged in during use. Users will enjoy the added mobility of its cordless design.
  • 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: Being handheld, this blower has a good maneuverability and is meant to be easier to carry around over a small period of time. When compared to other cordless handheld blowers, the Black+Decker LSW321BT stands out due to its lower weight: just 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: With a noise rating of 53 dB, this blower can be considered the standard for similar electric handheld blowers.

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).
  • 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 leaf 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+ 580 CFM LB5804 with up to 180 minutes of runtime).

Price comparison

As you can see from this dynamic chart, when compared to other cordless handheld 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

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

STRENGTHS:
  • Inexpensive
  • Smartech™ Technology
  • POWERBOOST Technology
  • Lightweight (3.7 lbs)
AVERAGE SPECS:
  • Acceptable Noise (53 dB)
  • Decent MPH (130 MPH)
WEAKNESSES:
  • No Speed Variation
  • Low CFM (80 CFM)
  • Low autonomy (25 mins)
