I want to try the drip method, but I ordered autos, I really want to try 5v, but I don't want to spend a huge amount of money. I was thinking about getting either a 5v passthrough, or an ego battery, since I already have a decent amount of 510 stuff. I was looking on vapor kings and I came across this. ego usb passthrough. Should I get that? or a regular 5v passthrough, they have one there or just a regular ego battery and charger. Also I remember seeing something about a 5v mod for the ego battery. Is that easy and or safe to do?
