As great as it looks in the palm of your hand, the IQ by DaVinci really shines when it comes to performance. It has a fast 16-second heat up time to 230F and the temperature is adjustable from 250F-430F. When vaping dry herbs, essential oils, and concentrates, the efficient distribution of heat is a must. This unit spreads heat evenly over a larger surface area to produce vast amounts of flavorful vapor. The pure flavor is assisted by the ceramic zirconium used in the air path. A boost and standby mode also helps to conserve battery life. The battery itself is an 18650-style rechargeable that can provide up to 1.5 hours of continuous use before needing a recharge. It takes approximately three hours to charge the battery to full capacity with the included charger.
