Which has more power?

The DeWalt. Its impact driver delivers 1,700 in-lb against 1,450 in-lb for the Porter-Cable, and its drill spins to 3,200 RPM.

Which is better for tight spaces?

The DeWalt drill, at 5.88 in of head length versus 8-1/4 in for the Porter-Cable. The Porter-Cable driver is close at 6.9 in against 5.1 in.

Which is lighter to use overhead?

The Porter-Cable. Its drill weighs 3.5 lb and its driver 3.3 lb, while the DeWalt kit weighs 8.28 lbs with batteries and bag.

Is the DeWalt worth the extra money?

There is almost no extra: $149.00 at The Home Depot versus $149.99 at Arbor as of November 3, 2026. At that gap the DeWalt's torque and brushless motor make it the better value.

The DeWalt's brushless motor should outlast the Porter-Cable's brushed motor. Both share the same 1.3 Ah battery size, and Porter-Cable buyers more often report batteries dead on arrival.

Do the batteries interchange?

No. DeWalt 20V Max and Porter-Cable 20V Max use different mounts, so each kit's batteries only fit its own brand.
