Black and Decker Cordless Blower (20V): Tool Review & Comparison

According to our research, the American tool manufacturer Black and Decker has three different 20V blowers in its assortment. These are the Black and Decker Cordless Blower LSW 321, the Black and Decker LSW 221 as well as the BCBL700D1 Axial Leaf Blower. In this review, we will look into the characteristics of the three blowers. In chapter 1, we will introduce the Black and Decker LSW 321 in detail. Hereby we focus on the following key evaluation criteria: performance, ergonomics, technology and delivery scope/ price. This is followed by brief presentations of the other two Black and Decker 20V blowers in which we will also highlight the differences between the Black + Decker LSW 321 and the Black and Decker LSW 221 respectively the BCBL700D1 (chapter 2). In chapter 3, we are presenting the most important tool features and specifications so that you can make an informed decision.

I. Black and Decker 20V Blower LSW 321 – Review

The Black and Decker LSW 321 is designed with comfort and easy handling in mind. Therefor it offers a great combination of power, endurance and ease. The cordless leaf blower is part of the Powercommand Family of tools by Black and Decker, helping solve common user frustrations while using Outdoor Power Equipment.

A huge advantage of the Black and Decker Powerboost Sweeper is that all 20 Volt batteries from the companies 20V MAX System can be used interchangeably to power the Black and Decker 20V blower. You can purchase the batteries together with the tool or separately. Subsequently you can decide on simply having one Black and Decker 20V battery for all your 20V MAX System Tools, or getting a few back-up batteries in order to always have fully charged spares, for example when working on bigger projects.

1. Performance: 8/10

Black + Decker cordless blower review: Tool in action The tool is operated with a 20 Volt battery. It impresses with a maximum air speed of 130 miles per hour (mph) and a maximum air volume rating of 100 cubic feet per minute (cfm). The air volume may be on the lower end but this is still more than enough for private use. The performance data shows that this tool can be easily compared to other leaf blowers of the 18-/ 20 Volt category, for example the Dewalt DCE100B and the Makita DUB 182. All in all, you will be adequately equipped to free your porch and sidewalk of grass clippings, debris and leaves.

The Black and Decker 20V blower has one speed setting and a powerboost. You can easily operate the powerboost while holding the tool with one hand, giving you complete freedom of your other hand. The powerboost setting is activated by a push-and-hold mechanism, ensuring that no unnecessary energy is wasted.

2. Ergonomics: 10/10

The device from Black and Decker weights less than other 20V blowers and all leaf blowers from the 40V category. Its sleek design and quality lightweight materials are main reasons for the comfortable 3.7 lbs. In addition to its comparably low weight, the Black and Decker cordless blower has a micro texture soft grip and an ergonomic design. As a result you can easily operate the tool with only one hand. But for safety reasons be sure to firmly hold it with both hands when initially turning on the machine. The top noise level of the Black and Decker 20V blower is at only 66 Decibel, putting it on average terms on the very lower end of the category.

3. Battery- & charging technology: 9/10

Battery technology:

The device can be operated by any Black and Decker 20V battery from the 20V MAX System. The system includes batteries with different capacities of ampere-hours (ah). The ah rating measures how much energy can be stored in the battery. The different batteries included in this system have capacities starting at 1,5 and going up to 4 ah.

The runtime of a 2.0 ah battery is up to 25 minutes, when using the powerboost very sparingly. This might not be the largest battery capacity, but from a user’s perspective, it’s rare to use the powerboost for more than a minute here or there. If a 4.0 ah battery is used, the run times are increased by nearly double. That is to say up to 45 minutes.

Charging technology:

Overall, it takes around 10 hours to fully charge a Black and Decker 20V battery with the included standard charger. However using a Black and Decker fast charger reduces the charging time one hour or two, depending on the battery size.

The Black and Decker 20V battery and charger set, which can be purchased separately even comes with some convenient technology. With the 20C MAX battery you can power the entire family of 20V MAX tools. With its SMARTECH technology you can use the app to locate and lock your tools. Furthermore, you can use the app for general monitoring purposes. In addition, it can charge up your phone and other mobile devices.

Compatibility with other 20V devices from Black + Decker:

As mentioned before, any Black and Decker 20V battery from the 20V Max System will work with the Black + Decker 20V blower LSW 321.

4. Scope of delivery & price: 9/10

Above all, we think that the Black and Decker cordless blower LSW 321 is offered at a reasonable price. The full set includes the tool, one Black and Decker 20V battery (usually the 2.0ah pack) and a charger. Even if you purchase the separately sold gutter attachment and a more powerful battery, this still makes the Black and Decker LSW 321 one of the more reasonably priced battery leaf blowers on the market.

II. Other Black and Decker 20V Blowers

Black and Decker 20V Blower LSW 221

The Black and Decker LSW 221 has a very similar design to the LSW 321, which means that easy handling is par for the course. Offering the same great combination of power, endurance and ease.

As with the previously introduced blower, all 20V batteries from 20V MAX System can be used interchangeably to power the Black and Decker LSW 221. A battery is included in the set together with the tool but can also be purchased separately. Consequently, you can simply utilize the one Black and Decker 20V battery for all your 20V MAX System Tools, or purchase multiple back-up batteries if you prefer to have a continuous supply of fully charged batteries.

The Black and Decker LSW 221 can boast the same stats as the LSW321: a maximum air speed of 130 mph and a maximum air volume rating of 100 cfm. The blower also has the same ergonomic stats coming in at a comfortable 3.7 lbs and only 66 Decibel. Just as the LSW 321, the Black and Decker LSW 221 only has one speed setting. The only difference between the Black and Decker LSW 221 and LSW 321 lies in the powerboost functionality. The first mentioned device lacks this option which is, however, reflected in a cheaper purchasing price.

Black and Decker 20V Blower BCBL700D1

The Black and Decker axial leaf blower BCBL700D1 has a different design than the two other sweepers. This leaf blower has a shorter yet wider blow tube, and the design is more compact. As the Black and Decker LSW 221 and LSW 321, the device is designed with efficient yardwork in mind, exhibiting a great combination of power, endurance and comfort.

As with the two previously introduced sweepers, all 20V batteries from the Black and Decker 20V MAX System can be used interchangeably to power the axial leaf blower. A Black and Decker 20V battery is included in the standard set together with the tool but there are also sets which include an extra 3.0 ah battery.

The Black and Decker cordless blower BCBL700D1 does have some very different stats than the previous sweepers. It only comes in at 90 mph but it does move air at up to an impressive 320 cfm, clearing debris and grass clippings from your yard or porch. A huge advantage the device has over the Black and Decker LSW 221 and LSW 321 is that the blow tube has an integrated scraper at its lip, designed to loosen suborn and dried up debris.

The tool does not have a power boost, but it does have 2 speed control settings. The two speed settings let you select between a more delicate option for work around flowerbeds and the more powerful setting for cleaning up more stubborn debris from your backyard. The Black and Decker axial leaf blower is a little bulkier in design than the two other tools, but only comes in at 3.8 lbs, making it only slightly heavier The noise rating of only 61 Decibel also makes it somewhat quieter than the Black and Decker LSW 221 and LSW 321.
