Yep, I have some 12V Milw and 18V Ryobi, so I'm really only looking at those.

All of the new Ryobi stuff has the "push a button, walk away, auto-shutoff at programmed pressure" feature. So that'll be my only option.

Good stuff, thanks for the response.

The 20 volt lithium battery tools are a big step up over the older types.
The next gen will be better yet....buy the newest.

A little off topic, but the latest gadget for cyclists are these battery powered mini-pumps. I haven't bought one - yet - I still have a whole bunch of Co2 carts to use up, but apparently they work pretty well, hold enough juice for a few fills, and are light and small so not a huge weight penalty.

I am thinking of getting one too. Saw someone used it and its pretty slick, cheap too. I ride tubeless now, so the days of sitting on the side of the road swearing away is just about over BUT, if a big enough cut on the tire, Ii will hear it from my wife when she comes for the rescue.

Since you already have the Milwaukee batteries, you should get their pump. Its a very well built unit I look forward to using it. I know it sound strange, but I do. I grab a drill or something, its no big deal but pumping up tires with ease is cool. Set it and come back after getting a drink of water is all done.
