I've got kind of a tall order. One of my mods crapped out yesterday after I had it for about 4 weeks never dropped it treated it like it was a baby. I need some names of inexpensive regulated external battery mods. I'm not taking it outside I don't intend on dropping it it shouldn't get wet other than an occasional leakage of ejuice. I don't care what it looks like I don't care if it's single or dual battery I do vastly prefer it to take 18 650 days but if it's with an adapter that's fine actually that's great. And the thing that might keep it lower end I don't need it to go over 50 Watts and I really don't even need it to go over 35. I don't care if it goes higher but I don't need it to I also don't care what it looks like or how big it is or how heavy or light it is. I just want something that's likely to work for a while. Extra points for being pretty basic because the less crap going on with it the less likely something's going to break but I'm not quite ready for a Mech mod yet
