Will this fit my 21V leaf blower?

Only if the battery socket and contacts match your tool. 21V is a common nominal voltage but connector shapes differ between brands, so compare the socket before buying.

How long does it run on a charge?

The listing claims up to 120 minutes, but expect much less in a chainsaw or under heavy load. A 2.0Ah pack suits trimming and light blowing.

How long does it take to charge?

The listing states a full recharge in 1.5 to 2 hours with a compatible charger. Charge time depends on your charger's output.

Is it worth it over a brand-name battery?

It can be a cheaper spare for light use, but the 30-day warranty and unknown cell brand make it a risk for daily or heavy work. Compare against an OEM pack for your tool.

The listing describes the battery pack only. A charger is not stated as included, so confirm before ordering.
