The tool battery ones can draw more power (inflate faster) and can be used for e.g. bike tires or other portable applications. I decided it wasn’t worth it to me… The tool battery is just another thing that’s expensive and has to be kept charged.

Yeah those are pretty good, I just decided in favor of one powered by the car instead of a tool battery. There are trade offs either way.

I have one from Home Depot, Husky brand, seems durable, works fine. Heavier duty ones exist but I haven’t needed that.

Thanks, though I’m hoping for one that doesn’t break. I should check whether my broken one is under warranty.

Plug-in Norelco. I can check the model number of mine later.
