Overview of the Little Wonder LB390H-SP

  • Power: The LB390H-SP gas-powered blower, manufactured by Little Wonder, is rated for a max air volume of 2530 cubic feet per minute (CFM) and a max air speed of 160 MPH.
  • Handling: Walk-behind blowers such as the Little Wonder LB390H-SP are the most powerful. They are wheeled, heavy, have to be pushed and are mostly used by professionals. This push blower is also self-propelled, a feature that makes pushing it around easy despite its heaviness.

  • Speed Settings: For those who are keen on having complete control while operating their leaf blower, the LB390H-SP offers variable speed settings.
  • Fuel Tank: It has an average fuel capacity for a walk-behind blower, with a tank that holds around 204.8 fl. oz of fuel.

The Little Wonder LB390H-SP's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Little Wonder LB390H-SP compare with similar leaf blowers.

  • The air speed of the Little Wonder LB390H-SP maxes out at 160 MPH. While more than adequate for many jobs, its air speed is below average among other gas-powered walk-behind blowers. For the fastest air speed in this category, you may want to consider the Billy Goat F1802V, which can expell air at a velocity that can reach 200 MPH.
  • Regarding its air volume, the Little Wonder LB390H-SP boasts an impressive airflow that can reach 2530 CFM (Cubic Foot per Minute). This places it amongst the most powerful gas-powered walk-behind blowers. If air volume is important to you, the Billy Goat F1802V, with 2900 CFM, could be in your good books.

OPTIMAX™ Technology

The Little Wonder LB390H-SP benefits from a reversed angle fan blade that is a lot different from other blowers: it improves the fan efficiency and, when combined with a scrolled housing, allows the blower to move more air than many other wheeled blowers. The air deflector in an Optimax™ walk-behind leaf blower splits the airstream to direct the fastest moving air where it’s needed the most. Moreover, its low lying discharge chute gets the airflow closer to the surface. For surface treating, this allows it to clear small particles. For surface drying, this allows it to move standing water.
