The Smok AL85 is the more compact version of the Alien mod. It has an operating power of up to85W. We recommend this mod for intermediate vapers as this is a more advanced system. The AL85 has the same appearance as the 220W alien except for the screw cap next to the tank. This cap houses the single 18650 battery in a canteen styled compartment, removing any chance for battery shifting or damage. The AL85 features multiple working effects, which allows you to change when you get the maximum power in your coils. The working effects are: Soft, Normal and Hard, with hard being the fastest maximum power. The 510 connector is seated with a 27mm deck meaning that any 25mm tank will fit with no overhang. The large OLED screen displays every bit of information you'd need, and then some. Showing everything from working power, puff counter to battery life. This mod also allows you to change the working effect, which can make the hit harder or softer. This setup is a great bridge between portability and power.
