I just started vaping two days ago with a wonderful eGo and I really like it. My question is for a dear friend (the one who got me started vaping!). She has a Joye 510 that she hasn't been using because she didn't have a charger. I just learned she had the good e-cig this morning and promptly ordered her a new USB charger and car adapter. I love her! hehe. But what I want to know is if she can get rid of the attomizer/cartridge combo and go with an straight cartomizer with higher juice capacity? I just ordered a few good dual coil cartomizers that are highly recommended for my eGo and I want her to have as much enjoyment as possible with her fine 510. Will these work with any 510 with a 3.6 or 3.7 volt battery?
