you can charge both the elegant and you are set!!! I have gotten spoiled by these cause I forget to charge them because they last,,,,,,i keep 2 stick styles (so that it feels like i have a cig in my hands) and have both the elegants.....one for "just in case" but i never have needed the extra elegant. I go overboard when i can go out.....but ususally dont need anything else.
I do know that the ce2 and my diamonds have really helped me with saving a lot of ejuice. the batting in the diamonds absorb better then i have seen a carto absorb the ejuice and also about the duals,,,u dont get that nasty batting taste after a few days!!! they last!!! and lol, with the diamond you can see if the batting is drying up and you can top it off with ejuice if it starts getting dry. and the ce2 you dont get the batting which is cool and you can see what is in there. the first time i filled a ce2, i filled it til full,,,then 5 min later i looked over and half the ejuice wasnt there,,i was wtf, its leaking?? it wasnt leaking,,,i then noticed that the wicks were like translucent, you couldnt see them,,,they are thick wicked and the ejuice was absorbing the heck out of the ejuice,,,thats where the ejuice went,,,and they last,,,,even when the ce2 looked empty, it wasnt.....i knew to fill when i could start to see the wicks again.
the vortexes,,,i love these things...these for me were the easiest to fill-- although i dont have the hang of the alf thing yet

lololol. there is a lot to experiment with. and what i like about gotvapes is there is variety and you can choose what carto you like and is best for you,,,,love variety !!!
good luck to you
