What is included in the DCK302P2 kit?

A 1/2-inch mid-range impact wrench, a 3/8-inch XR impact wrench, an LED handheld area light, two 20V MAX XR 5Ah batteries and an 8-amp fast charger.

Is the 1/2-inch wrench strong enough for lug nuts?

It is a mid-range impact wrench, so it handles most passenger-car lug nuts and brake work. For heavy truck or rusted fasteners, a high-torque model is the better fit.

Do the batteries fit other DeWalt tools?

Yes. The 5Ah XR batteries use the DeWalt 20V MAX slide pack, so they work across the 20V MAX line.

How fast is the 8-amp charger?

DeWalt rates it at twice the charge rate of the DCB115 charger, so the 5Ah packs spend less time on the charger between jobs.

Does the LED light run on the same batteries?

Yes. The handheld area light runs on the 20V MAX batteries in the kit, so you can swap packs between the light and the wrenches.

Is this kit a good choice over a single impact wrench?

It makes sense if you want both 1/2-inch and 3/8-inch impact sizes plus a light and spare battery. If you only need one size, a single-tool kit covers it with less to carry.
