The Innokin Zlide Tube Starter Kit is powered by a 3000mAh rechargeable battery with 16W max output. Paired with the sliding top refill 2ml Innokin ZLIDE MTL Tank, the ZLIDE Tube Kit can utilize coils from the Z-Coil series to create deliciously flavored clouds of vapor. With smart coil sensing technologyny, any Z-Coil with a resistance greater than 1.0ohm will force the Zlide Tube to regulate itself to 13 watts and any Z-Coil less than 1.0ohm will force the Zlide tube to regulate itself to 16 watts.
