7L Bottle recommendations?

Yes, but I would have to walk back to the car to use it, which defeats the requirement for a lighter bottle. I could leave the 7L steel one in the boot.
There are usually 2 to 4 of us using my bottle and the walk back to the car every time one needs filling isn't realistic.

Hello, I was looking at those 12 volt Compressors that use a drill type battery like the Umarex PAC 400

That one is heavier than the bottle, plus you need moisture trap etc as well.
I dont have a problem getting a bottle filled as I drive past DAI and Brierly Guns every day, plus they fill at the range i use.
