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 handheld leaf blowers of similar voltage (between 18 and 24V).

  • It can propel air from the nozzle at speeds going up to 130 MPH, placing it at the top of its class for air velocity among battery-operated handheld blowers. If you wish to benefit from air expelled at the fastest possible speed, the Makita XBU07SM1 and its 143 MPH could be an option to consider.
  • With a maximum airflow of 100 CFM (cubic feet per minute), this model is on the lower end in terms of air circulation for cordless handheld blowers. For the highest air volume, you may want to have a look at the Ryobi PBLLB01K, which boasts with 510 CFM.
  • Within the voltage range of 18V to 24V, the LSW321 falls within the typical autonomy range for cordless handheld units, delivering up to 25 minutes of operation on a full charge. If autonomy is an important factor for you, the Ryobi PBLLB01K can run for up to 60 minutes and could be worth considering.

Price comparison

As you can see from these interactive charts, 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.

Questions & Answers

I have lost the original box for my LSW3211 blower. Did it come with a battery charger? If not, how do I charge the battery? Thanks. (Asked July 26, 2021)

The unit does come with a battery charger. If you lost it, the LCS1620 (opens in a new tab) is the charger you're looking for.
