Overview
Running on a 20 volt battery, the Porter-Cable PCCK647LB reaches 2,700 RPM at 14 amps while weighing 4.7 pounds. It carries a 4.8 star average across 2,008 ratings, with about 100 bought in the past month.
Cordless impact tools trade the unlimited runtime of a corded model for freedom of movement, which matters most on jobs that move around a house or site. The listing does not state a torque figure in inch-pounds, so anyone planning heavy bolt or lug-nut work should confirm that spec elsewhere before relying on this tool for it. A 4.8 star average across a large ratings pool suggests it performs well for the general fastening tasks it is aimed at.

Who it's for
Suits DIYers and light trade use who need a cordless impact tool for general fastening around the house or job site. Not the pick for heavy automotive or structural bolt work without confirming its torque rating first.
Strengths and trade-offs
Drawn from this product's published specifications.
- 20 volt cordless power source
- Compact 4.7 pound weight

- 4.8 star rating across 2,008 ratings
- Torque output in inch-pounds not listed

Performance notes
A 2,700 RPM top speed combined with a 14 amp draw is characteristic of a driver-class impact tool geared toward speed on smaller fasteners rather than maximum torque on large bolts. Battery power removes the cord but adds weight and finite runtime per charge, a tradeoff most buyers accept for the added mobility.
