The iTaste VV 3.0 is the smallest variable wattage or regulated wattage e-cigarette on the market (to my knowledge at the time of writing this at least.) This little e-cig packs a heck of a punch with it’s 800mAh internal battery that you can charge while using the e-cigarette – passthrough for the win! It has a variable voltage and wattage function – ohm checker – this is one of the best eGo (kinda) sized e-cigs i’ve seen. It has a full eGo connection so you can use it with your favorite tanks – and a bright LED screen to display useful information. A lot of performance for so little a price!
