I use a Ryobi pump with my drill/impact driver batteries. Works really well so would imagine the DeWalt equivalent would be just as good. I use a separate digital pressure gauge, and just over inflate by a PSI or two and then drop it down to where I want them for the conditions/intentions... Either way I'd go for one with a clamp on fitting not a screw on, easier to get accurate pressures and since our cars are so sensitive to pressures...
