How long does a 4.0Ah battery last?

ZEGJAW does not publish a run time. Expect the longest use on low speed and the shortest at full blast. The second battery lets you swap and keep working.

Does it really vacuum leaves?

It has a vacuum function, but on combo blower-vacuums the vacuum is typically weaker than the blower. It handles loose, dry leaves and light debris better than wet or heavy piles.

Two 4.0Ah batteries plus the vacuum parts make it heavier than a bare blower. The weight is the trade-off for cordless power and dual function.

What comes in the box?

The listing states two 4.0Ah batteries. Check the box contents for the charger and any vacuum tubes or collection bag before you buy.

How does it compare with a corded blower?

Corded blowers usually deliver stronger, constant airflow with no battery limits, but you are tied to an outlet and a cord. This one trades some raw power for portability.

Is it good for large yards?

It is better suited to small and mid-size yards. Large properties with heavy fall cleanup will likely need more run time and airflow than a 40V combo provides.
