Nautilus coils are designed for use with the Aspire Nautilus AIO and Nautilus tanks, including the 2S. Nautilus coils are built with high-quality cotton and a unique patented nichrome coil, which provides even heating and sustained performance over its long lifespan. 

The 0.4-ohm coils are to be used at 23-28 watt outputs. They are best suited to high-VG or 50/50 (PG/VG) e-liquids blends. The 1.8ohm coils are best used between 9-13W and have been optimised for use with nicotine salt e-liquids. 

Not sure which resistance level to choose? Higher resistance levels tend to be more popular, but please see below for more information:

Lower resistance:

• stronger throat hit
• more heat
• more vapour
• uses up more battery life
• uses more e-liquid

Higher resistance:

• smoother throat hit
• less heat
• less vapour
• uses up less battery life
• uses less e-liquid
