This new two 18650 battery device from Sigelei has a carbon fiber and zinc alloy body featuring a .91" OLED display screen. The device is capable of going from 10 watts all the way up 213 watts of power.
6 different modes to choose from by simply pushing the fire button 3 times:
-TCR (Temperature Coefficient of Resistance)
-TFR (Temperature Factor of Resistance)
It also contains a "power up" function, that will allow you preheat the coil, you can set it to fire at 120 watts for one second and then after that second it will go back to whatever wattage you have the device set to. Kinda nifty :)
