Ryobi 40V Whisper Series 550 CFM Leaf Blower Review

Ryobi 40V Whisper Series 550 CFM leaf blower highlights quiet operation

Battery operated blowers make great strides in performance, but not everyone needs more than 20 Newtons of blowing force or the price associated with it. We brought the Ryobi 40V Whisper Series 550 CFM leaf blower to see who it would work for.


  • Quiet operation
  • Swivel handle
  • Inline jet fan design
  • Excellent value for money


  • No cruise control
  • Not an option for bare tools

Ryobi 40V Whisper Series 550 CFM leaf blower performance

Blow force

Ryobi specifies this model to be 125 MPH airspeed and 550 CFM for air volume. As usual, we hooked up our handy Dandy dynamometer to see how the performance compares to other blowers.

With the 4.0 Ah battery supplied, the brushless motor delivered 9.8 Newtons at full throttle and 13.9 Newtons with the turbo button. When switching to a 6.0 Ah battery, these values ​​set exactly the same, although they were a bit higher right at the beginning of the test.

Residential level gas blowers start at around 12 Newtons, so we’ll use this as our yardstick. This model from Ryobi surpasses it with the turbo mode and deserves a thumbs up as a gasoline substitute.


We carried out our runtime tests with a 4.0 Ah battery. At the high level, we were able to run the fan for 21 minutes and 26 seconds. Started with the turbo button, it ran for 12 minutes, 43 seconds. For most residential lawns up to half an acre or so, you’ll be in tip-top shape with just one battery.

Noise level

The job of any blower is to use the airflow to remove debris, and some work more quietly than others. Ryobi advertises this model with 59 decibels based on ANSI standards.

We like to measure from the ear of our operator (~ 36 inches) and the numbers keep getting higher. At full throttle we measured 72 dB (a) and 80 dB (a) with turbo.

This is remarkably quiet considering most of the wireless blowers we tested run 85+ decibels. However, Ryobi’s 730 CFM Whisper Series blower actually tested a little lower.

Ryobi 40V Whisper Series 550 CFM Leaf Blower Design Notes

It’s instantly clear that Ryobi’s design for this blower is a different look than most of the others. The handle not only offers space for the battery, it can also be swiveled. To adjust the position, loosen the gray button on the side, swivel the handle into the desired detent and tighten it again.

Tilting the handle back provides a slightly wider nose angle and helps keep your wrist at a more natural angle. It might sound like a trifle, but it really feels more comfortable when we use it.

Controls are straightforward with a variable speed trigger and turbo button. There’s no cruise control so you’ll have to press the trigger whenever you want a speed slower than full throttle.

The blower alone weighs 6.7 pounds and with the 4.0 Ah battery it comes to 9.8 pounds. Although it crosses the 10 pound mark, it’s not a hassle to carry and use.

Additional functions

  • Jet fan design
  • Compatible with all Ryobi 40V batteries

Ryobi 40V Whisper Series 550 CFM Leaf Blower Price

You have several options to purchase this blower from The Home Depot. As a kit with a 4.0 Ah battery and charger, it costs $ 199. You can add a second 4.0Ah battery and the kit costs $ 338. There is no bare tool option available.

When you consider that a 4.0Ah battery / charger starter kit alone costs $ 198, this $ 199 kit price point is incredibly attractive.

The bottom line

If you’re blowing hard surfaces like driveways and sidewalks, the Ryobi’s 550 CFM Whisper Series blower is a great choice and it’s remarkably quiet. It does a good job moving dry leaf debris around your yard for collection. When it comes to wet dirt, it’s not as effective as some of the more powerful cordless blowers, including Ryobi’s own 730 CFM model. On the other hand, it’s not nearly as expensive either.
