I am now on my 3rd $400 1/2in cordless impact in the last 12 years. Used mostly for lug nuts. The first was an 18 volt Milwaukee rated around 250 ft lb. Maybe put out more like 100 ft lb. Had to loosen every lug nut by hand first, but worked great for running nuts off and on. 2nd wrench was a Ingersoll 19.2 volt rated for around 350 ft lb. Same thing. Wouldn't budge a lug nut torqued to 150. Got so tired of loosening thousands of lug nuts by hand, and bought the newest Ingersoll 20 volt rated for 780 ft lb. This thing is amazing. Cranks lug nuts off better than my air impact. The motor has tremendous power, and solid impacts. You really have to hang on to this thing. Love it!!! The only downside is even though it has variable speed, it has so much torque, it is very hard, even with a light touch not to over torque when snugging up lug nuts. No more air hose for me!
