I have a ego t which I love but I want to try out dripping. I understand that I can use the batteries from my ego t and just buy regular ego attys for it. Just wanted to know the difference between the type a and b attys and if most types of drip tips fit both? I would like to drip while at home and take my tank system with me when I am out. also how many drips do I drop each time. Please help. yew!
