Lithium ion vs Air

Can't paint with a battery. In my experience, an air tool will weigh less than its battery operated counterpart. Unless there is a battery operated tool "system" out there, the shop is going to be cluttered with power taps and battery chargers of every description.

Can't beat a good battery powered tool for convenience. I took a battery powered Dewalt reciprocating saw into a salvage yard once and finished a half hour hand tool job in under five minutes. I could have had air in the yard, but then I would have need to drag 250 ft. of air hose to the job.

I have variable speed drill motors in air, AC cord, and DC battery form. I like the air drill for its light weight. The AC cord drill is a torque monster that takes a lot to bog it down. I like the battery tools for being able to grab and go without a plug in (hose or cord) hassle.
