iStick 20 Watt
The ELeaf iStick 20 Watt from iSmoka is one of the most popular devices in the world, and with good reason- it's affordable, easy to carry and reliable, with enough battery life to last through the day (and then some), and enough power to satisfy most folks as their go-to, all-day device. Built-in ohm reader (even for subohm coils, though it can't fire them); variable voltage or wattage (3 clicks to switch between them), adjustable in .1 increments.
Note that 22mm atomizers will have a slight overhang on this device. It doesn't bother us (or most people), but if that's an issue you might want to 1) use the included eGo adapter with a beauty ring; or 2) check out the 30W, which has a built-in beauty ring.
