Thanks! The pictures don’t have a quarter or banana for scale and it’s really hard to find any videos of these devices. So the taller one is actually the size of a pack of cigs? So the shorter one is half the size of a pack of cigs but not portable?
Thanks which one is best to use with a bubbler? I’m thinking the shorter one but the longer one is the portable one with battery? Can you still use it plugged in if the battery dies or pass thru charging and use at same time?
