Is this blower strong enough to replace a gas backpack blower?

For most yard and crew work, yes. At 1000 CFM and 190 mph it matches or beats many mid-size gas backpack blowers, though the largest commercial gas units still move more air.

How long does it run on one battery?

Run time depends on the battery and speed setting. Expect short runs at full power and much longer at lower speeds; crews typically carry several high-capacity 56V batteries.

Which Ego batteries does it use?

It uses Ego's 56V ARC Lithium batteries, the same packs as Ego's other outdoor tools. Larger Ah packs give longer run time but add weight.

Is it good for residential use?

It works well for large yards with heavy leaf loads, but it is more blower than most small lots need. For smaller properties a handheld Ego blower is lighter and easier to store.

Does it come with a battery and charger?

That depends on the kit version you choose. Some bundles include a battery and charger; tool-only versions do not, so check the box contents before buying.

How loud is it compared with gas?

It is quieter than gas backpack blowers and produces no exhaust fumes, which makes it easier to use near homes and in early hours where gas blowers are restricted.
