Hello fellow vaper's, I just got home from my local vape shop The Vapor Room. I stopped up to purchase a few new 510 attys and cardos as I was talking to the store owner the vv (variable voltage) options came up. Since they only carry genuine joyetech merchandise I asked him when they were coming out with a vv mod. He stepped in the back room and came out with what i thought was a provari. Boy was I wrong he let me see it and it said joyetech and was a real nice unit. I believe he said it was a 2600 mah battery but was not vv. He told me it will do a constant 3.7 volts which would be a improvement. I was just checkin to see if anyone has seen them or heard of them???
