It is rated for a max air volume of 247 cubic feet per minute (CFM) and a max air speed of 98 MPH. This balance means the blower is suitable for light clearing across small yards, patios, driveways, or garden paths.
The BGA 45 is equipped with an 18V brushless motor and runs on battery power, enabling mobility without a cord. It features a 2.0Ah battery that is integrated into the unit, and allows the user to operate the BGA 45 for an estimated 10 minutes on a full charge.

The Stihl BGA 45's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Stihl BGA 45 compare with handheld leaf blowers of similar voltage (between 18 and 24V).
- At only 4.4 lbs (bare tool), the Stihl BGA 45 offers a lighter option within the cordless handheld blowers in the 18 to 24V range. Should weight be a deciding factor, the Worx WG543 is worth a look at just 2.3 lbs the bare tool.
- Maxing out at 98 MPH at full power, this blower is on the lower end in terms of air speed for battery-operated handheld blowers between 18 and 24V. For the fastest air speed in this category, you may want to consider the Makita XBU07SM1, which can expell air at a velocity that can reach 143 MPH.
- It’s capable of expelling a maximum air volume of 247 CFM (cubic feet per minute). This places it at the low end compared to other cordless handheld blowers with a comparable voltage. For the highest air volume, you may want to have a look at the Ryobi PBLLB01K, which boasts with 510 CFM.
- Autonomy-wise, with up to 10 minutes of autonomy on a full charge, the BGA 45 is on the low end when compared with other cordless handheld units of similar voltage. To enjoy the best possible autonomy in this category, you could have a look at the Ryobi PBLLB01K which offers up to 60 minutes of runtime.
- Because larger batteries naturally increase runtime, it can be helpful to consider runtime efficiency, a measure of how effectively a blower uses the energy available. In terms of runtime efficiency, the Stihl BGA 45 ranks on the lower side, delivering less runtime per unit of battery capacity than many comparable battery-powered handheld blowers. If you are focused on getting more use per charge, the Ryobi ONE+ SWEEPER P2102 offers the highest runtime efficiency, at 1.28 minutes per Wh.

User Reviews
Stihl Bga 45 product is inferior, over price and poor quality.
Bad customer service.
I am very disappointed in this product! Especially that it’s manufactured by Stihl which is a good name in power tools. This is a very poorly manufactured product as after about 25 battery charges the battery will not take a charge and there is no way to replace the battery or to order one for replacement. A dealer has to be involved and the cost would be close to buying a new one. Sorry But I think this is a very poorly made product
I agree with all above, great while the battery works, but eventually won’t take a charge. Will be asking if Stihl will back their product now
Not worth the price. Good power for a battery unit but needs more amp hours. 10 minutes of run time barely clears a driveway, never mind leaves…
The BGA 45 blower is a poor purchase choice in my view. Does not hold a charge very long and once you have re charged it 50 times more or less, it becomes a paper weight. Unable to accept a charge and battery is not removeable. Poor buying decision on my part as I thought Stihl was a better product, something similar to the chain saw, but I am wrong.
