Is this blower strong enough to clear a whole yard?

No. It is a light-duty handheld blower meant for small areas, patios and quick cleanups. For large lawns or heavy leaf piles, a higher-airflow cordless blower from a major brand is a better fit.

How long does the battery last?

The listing does not state a runtime figure. Expect short sessions per charge, since small 21V packs in this class typically run for a matter of minutes at full power. Charge fully before each use.

Can it blow light snow?

Yes, for fresh, light snow on steps, walkways and car surfaces. It will not move wet or packed snow.

Can I use it to dry my car after washing?

Yes. The airflow helps push water off the exterior after a wash, which is one of its intended uses.

Does it come with a battery and charger?

The product is sold as a cordless kit with a rechargeable 21V battery. Check the box contents on the listing for the charger before ordering.

How does it compare with a Worx or Ryobi blower?

Those brands offer more airflow, longer runtimes and batteries shared with other tools. This blower is simpler and lighter, with performance suited to light jobs only.
