The Aspire Nautilus X Replacement Coils bring Aspire's innovative U-Tech technology to mouth-to-lung enthusiasts seeking consistent flavour performance. Available in packs of five, these coils feature a distinctive U-shaped chamber that forces vapour to pass through the heating element twice, intensifying taste with every draw.

Designed for the Nautilus X tank, PockeX kit, Nautilus XS tank, and Rover 2, these coils cater to vapers who prioritise flavour clarity over cloud production. The range includes three resistance options, each built with Kanthal wire and Japanese organic cotton for clean, reliable wicking.

Key Features

U-Tech Coil Technology

Proprietary chamber design channels airflow through the coil twice before reaching your lips, delivering enhanced flavour depth.

Cross-Compatible Design

Works seamlessly across multiple Aspire devices, including the PockeX, Nautilus X, Nautilus XS, and Prime X with Nautilus pod.

Multiple Resistance Options

Choose between 1.8Ω and 1.5Ω for classic MTL draws, or 0.7Ω mesh for increased vapour whilst maintaining mouth-to-lung characteristics.

Why Nautilus X Coils Stand Out

These coils address the common vaper challenge of maintaining flavour intensity in MTL setups. The U-shaped chamber isn't just marketing speak; it genuinely alters vapour flow, reducing harshness whilst amplifying e-liquid nuances. Users report coil lifespans ranging from one to three weeks depending on usage patterns and e-liquid composition.

The organic cotton wicking eliminates break-in taste, allowing you to enjoy your e-liquid from the first puff. Higher resistance options suit ex-smokers seeking a familiar draw, whilst the 0.7Ω mesh variant provides a restricted lung hit for those wanting slightly more vapour.

Compatible Devices & Wattage Ranges

Nautilus X 1.8Ω (12-16W): Nautilus X Tank, PockeX Kit, Nautilus XS Tank, Rover 2

Nautilus X 1.5Ω (14-20W): Nautilus X Tank, PockeX Kit, Prime X with Nautilus Pod

Nautilus XS 0.7Ω Mesh (18-22W): Nautilus XS Tank, PockeX Kit (requires device capable of higher wattage)

All variants feature straightforward threaded installation, ensuring secure connection and preventing leaks.

Recommended E-Liquids

1.8Ω & 1.5Ω Coils: Pair with high-PG e-liquids in 50/50 or 60/40 PG/VG ratios. These resistances excel with freebase nicotine from 6mg to 18mg, as well as nicotine salts up to 20mg. The tighter wicking suits thinner liquids for optimal saturation.

0.7Ω Mesh Coil: Best matched with balanced 50/50 VG/PG blends. Handles slightly higher VG content (up to 60% VG) thanks to enlarged wicking ports. Recommended nicotine strengths: 3-12mg freebase or 10-15mg nic salts.
