Check my blogs for my carto swap method. I can do it with a full tank and no tools, and prime when out and about if necessary. But you are correct, almost not necessary as cartos dont just fizzle out quick like clearo heads, they tend to have a slow death so you can plan it pretty well.
I'll check it out. I can swap cartos with a full tank. I do that a lot for hubby. Heaven forbid I lose a drop of his precious all day vape as I maintain all his equipment. His all day vape is also the darkest, coil slaying, liquid I have ever come across, so I swap his cartos often. It's the priming part that takes the time for me.
