Is 250 mph enough to clear leaves?

Air speed alone does not clear leaves; air volume matters too. 250 mph is strong for a handheld, so it handles dry leaves on hard surfaces well, but heavy wet piles will need more than a single pass.

How long does the 4.0 Ah battery last?

Run time depends on the speed setting and load. Expect the longest run at low speed and much shorter sessions at full throttle; a spare battery is the practical fix for bigger yards.

Does it come with a battery and charger?

The listing specifies a 4.0 Ah rechargeable battery. Confirm the charger is included before buying, since some cordless tools ship as bare tools.

Is it quieter than a gas blower?

Yes. Electric motors avoid the engine noise and exhaust of gas blowers, so it is a better fit for suburban lots and early-morning use.

Will the battery fit other Encore 20V tools?

Encore's 20V batteries are designed to be shared across its 20V lineup. Check that your other tools use the same platform before relying on one battery set.
