Hey gang, Loving my Provari V2 and getting another one next month, but in the meantime I'm looking for something for my wife. She stole my Vamo from me because she is a little intimidated by the menu of the Provari, and is afraid she might lose it or something. I'd like the Vamo back. Hehe..... she normally vapes store bought 808/901 disposable carts with an adapter and I refill them for her. Thing is, she usually vapes in the 3 -4 volt range so 3.7 would be just fine. I 've been checking out the Provape-1, and I need to know if the 18490 batts that I have with my V2 will work in the PV-1? Thanks....I am extremely impressed with Provape's products and feel that she needs something of that quality without all the bells and whistles.
