The Aspire Zelos 2 is a unique, compact and lightweight kit. Powered by a 2500mAh built-in battery, it has a 50W maximum output and is paired with the Nautilus 2S Tank. This kit is versatile as it can be used for mouth to lung or sub ohm vaping depending on what coil you've installed. A range of output modes including variable wattage and temperature modes that allow you to configure the Zelos' performance. The Nautilus 2S Tank features a sealed top filling mechanism, for quick refilling and reduced leaking. An adjustable airflow gives you a greater degree of control over your inhale and the flow of vapour. You have the option of using the 1.8 Ohm Nautilus coils, which are designed for lower wattage vaping and a mouth to lung inhale. The 0.4 Ohm coils are designed for higher wattages and increased cloud production.
