Eleaf EC-A Coil uses super austenitic mesh winding stainless steel (AST-steel) material, which delivers ultra rich and pure flavor in an instant and supports longer lifespan than ever. This high-quality stainless steel is corrosion-resistant, rust-free, durable and has a very fast heating speed evenly distributed heat, bringing you first-class taste and vapor experience. 

The AST-steel coupled with the chip-set inside iStick Pico Plus could bring you the smart coil protection. The device stops output with the hint "DRY-PROOF"when it detects a lack of e liquid, protecting the coil from dry hit.

EC-A coil enters fresh air from the double-slotted airflow ring at the bottom of the Melo 4S tank, which can be continuously adjusted from DL to RDL through a wide air inlet : Eleaf EC-A 0.5ohm coils (Wattage Range: 20-40W), Eleaf EC-A 0.3ohm coils (Wattage Range: 30-50W) and Eleaf EC-A 0.15ohm coils (Wattage Range: 40-70W).
