Does it come with a battery and charger?

Many versions are sold as bare tools, with no battery or charger. Check the listing's contents; if it is bare, you need a DeWalt 20V MAX battery and charger.

What size sockets does it take?

Most DeWalt 20V impact wrenches use a 1/2-inch square anvil, which fits standard 1/2-inch impact sockets. Confirm the anvil size on the specific model.

Can it remove lug nuts?

Yes, on most cars and light trucks it has enough torque to remove lug nuts. Heavily rusted or over-torqued nuts may still need a breaker bar.

Is it worth it over a corded impact wrench?

If you already own DeWalt 20V MAX batteries, the cordless convenience is a clear advantage. A corded wrench can offer more sustained power for shop use but needs an outlet.

How does it compare with Milwaukee or Makita impact wrenches?

DeWalt competes closely on torque and build. Milwaukee's M18 and Makita's 18V lines are the main rivals; the best choice often comes down to which battery platform you already own.

What is the difference between this and an impact driver?

An impact wrench uses a square anvil for sockets and delivers much higher torque. An impact driver uses a hex chuck for bits and screws and is not meant for lug nuts.
