mvp v2

I just ordered a new itaste mvp v2 e cig that includes a charger and an iclear30 clearomizer. I have an iphone 5 and the charger cord included only allows charging off of the mvp for iphone 4 and droids. I was wondering if I would be able to use my iphone 5 cord with the mvp? Also is it safe to charge the mvp using my apple usb to wall converter or will this cause problems? I ask because I have fried 2 of my cords for my old e cig doing this and have been advised to charge using my computer. Does the same rule still apply?

Thanks for any replies!
