Eleaf iStick Pico 2 Mod is a compact Box Mod which comes with fast 2A charging by a single high-capacity 18650 batter and provides users with easy-to-use features, such as Smart mode. The battery is installed by unscrewing the threaded cap on the top of the device. The 510 connector on the side makes it compatible with tanks with a maximum diameter of 27mm without overhang. The mod will output from 1-75W in two different user modes: Power mode – this gives you full variable wattage adjustment; Smart – this is where the device senses the coil resistance and sets the mod output accordingly. Operate in a classic way using the ergonomic fire button and the adjustment buttons at the bottom. Information related to vaping is visible on the monochrome OLED display.
