Aspire Zelos X Review: 80W Single-18650 Mod, Nautilus 3 Tank

The Aspire Zelos X is the bigger, removable-battery sibling of the Zelos Nano. It runs on a single 18650 cell for up to 80W and comes with the 3mL Nautilus 3 tank, giving you a flexible mouth-to-lung to restricted direct-lung setup with a clear colour screen and full mode control.

It suits vapers who want swappable-battery convenience and the well-liked Nautilus coil range.

• Battery: single 18650 (sold separately)
• Output: 1 to 80W; Watt, Voltage, Bypass, TC and CPS modes
• Display: 0.96-inch colour screen
• Tank: 3mL Nautilus 3 (2mL TPD), top-fill
• Coils: Nautilus mesh — 1.0Ω (13 to 15W, MTL) and 0.3Ω (23 to 28W, RDL); takes the Nautilus coil range
• Airflow: 7-option airflow ring
• Charging: USB Type-C

The Zelos X keeps a slim mod profile with a bright colour screen and a removable 18650 battery, so you can carry a spare cell instead of waiting to recharge. The Nautilus 3 tank fills from the top and its seven-option airflow ring dials the draw from tight MTL to a looser restricted lung.

Up to 80W with Watt, Voltage, Bypass and Temperature Control modes gives you room to tune the vape on the colour screen. The 1.0Ω Nautilus coil is the tight MTL option (13 to 15W); the 0.3Ω opens up to a warmer restricted-lung draw (23 to 28W). Running a single 18650 means you can swap in a charged cell on the go.

What fits the Zelos X: tank and coils

• Tank. The Zelos X ships with the 3mL Aspire Nautilus 3 tank (top-fill, 7-option airflow).
• Coils. It uses Aspire Nautilus mesh coils — the included 1.0Ω and 0.3Ω — and is compatible with the wider Nautilus coil range. Grab spare Nautilus mesh coils.

Pros: removable 18650 (carry a spare); up to 80W with full modes and a colour screen; proven Nautilus 3 tank and coil range; 7-option airflow for MTL or RDL.

Cons: battery sold separately; larger than a built-in-battery pod.

Pairing: the 1.0Ω Nautilus coil suits Black Note nicotine salts and 50/50 blends for MTL; the 0.3Ω takes a higher-VG blend for a warmer draw. Explore the full Black Note e-liquid range.
