DEWALT DCBL770X1 Flexvolt 60V Handheld Blower, 3.0AH battery Review

DEWALT DCBL770X1 Flexvolt Blower

Manufacturer: Dewalt
Model number: DCBL770X1
Price: 269.00
Power source: 3.0 Ah [Flexvolt] and 9.0 Ah [20volt]
Motor size: Brushless
Weight: 9.8
DEWALT is expanding the FLEXVOLT System with Outdoor Power Equipment. The OPE Equipment lineup will include the new 60V Chainsaw, Handheld Blower, and String Trimmer, all featuring the new FLEXVOLT® 60V 3.0Ah battery.


The battery is 9.0Ah when used in 20V tools and 3.0Ah when on the Flexvolt tool. The FLEXVOLT System is backwards compatible with most of the existing DEWALT 20V tools, which now includes over 100 products

The DEWALT DCBL770X1 Flexvolt Blower has a brushless motor and had an average, continious runtime of 12 minutes.


When it comes to analyzing leaf blowers for performance the most important specs are the MPH and CFM numbers. CFM or MPH measurement units are both used to indicate the speed at which the air exits the tube. The higher the ratings, the better the blower will be at removing wet leaves, heavier debris, and leaves and twigs that are embedded in your grass.

The DEWALT DCBL770X1 Flexvolt Blower produces 423 CFM & 129 MPH. The Blower also includes a flat concentrator nozzle to increase air speed to 175 MPH for heavy duty debris. I attached it – and left it on!

Ergonomics and Controls

The DEWALT DCBL770X1 Flexvolt Bower is comfortable to use – weighs only 9.8 pounds. Its handle is large enough for gloved operation.

A variable speed trigger allows controlled blowing and a speed control lever can be set to hold the speed without having to hold down the trigger.

One thing we notices was that when the trigger is depressed fully the blower motor take a few seconds to ramp up to full speed.

There is a lock option to keep the tool from accidently turning on in the truck and draining the battery during transport or storage.

Noise Rating

The DEWALT DCBL770X1 Flexvolt Bower has a noise rating at 67.0 dB(A). OSHA recommends ear protection be worn within sound levels of 85dB.


The blower is set up for right-handed users with the speed control set up for the right hand thumb. The air intake is also on the right side of the blower – which results in left –handed users getting their pants sucked into the air intake.

Dewalt copied their XR blower design, but maybe should be looking at a new design with a rear or bottom intake.


The DEWALT DCBL770X1 Flexvolt Blower sells for $269 and  with a battery and charger. You can find it online here:

Bottom line, if you are looking for a powerful workhorse, you have found it right here.
This Flexvolt blower is a no frills, powerful blower. We’ve been using it to blow off out tools at the end of the day, and to clean the jobsite. It’s a powerful blower!
