The E-Roll is an E-Cig, from the famous Joytech brand. It mostly adresses itself to occasional smokers who are looking for an E-Cig. The E-Roll Kit includes two compact E-Cigs (9.5cm length, comparable to a classic cigarette) with automatic power up and a charger station. The charger station, with this smartphone like look, will serve as storage, but will also charge your E-Roll. The tank capacity of E-Rolls is 0.8ml. The battery of each E-Roll will allow you to smoke up to the equivalent of 5 cigarettes, and charges in 30 minutes. To facilitate your E-Roll fill-up, think about purchasing a needle flask. It will prevent you from dropping out liquid on the sides.
