I'm new to the electronic cigarette world and I started by buying the Joye Ego-T and the Joye 510-T. I didn't realize that you are supposed to use a special charger for the 510-T and instead I used the Ego-T charger for both my Ego-T and my 510-T. Now, two of my Ego-T units aren't working. Can I just get new atomizers or batteries or do I need to scrap the whole thing????
