Like the title says im wondering what APV's have a built in charger. I was looking at the evic and really like the fact that you can charge off of the apv with the battery in the unit. I work alot and always going places so something where I dont have to carry around multiple batteries and a sperate wall charger is ideal. The only reason I ask instead of buying the evic is to me, it seems complicated and full of alot of useless stuff I wont use. I want something simple I can adjust the voltage or wattage and vape. Also want it to display the resistance as I want to try rba's. Any info would be appreciated.
