Overview

The Aspire K3 Tank is a compact mouth-to-lung tank built around a straightforward, no-fuss vaping experience. It holds 2ml of e-liquid and uses a bottom-fill system, so refilling is quick and easy without needing to disassemble the tank. The fixed airflow keeps things consistent — there is nothing to adjust, which suits vapers who just want to pick it up and go. It runs on Aspire Nautilus BVC coils, a well-established coil range that is widely available and easy to replace. The tank body is constructed from stainless steel and Pyrex glass, giving it a solid feel and a classic look. At 18mm in diameter, it is a slim, neat fit for everyday carry.

Frequently Asked Questions
Which coils work with the K3 tank?

The Aspire K3 tank uses the extremely popular Aspire Nautilus coil series. While intended for use with the 1.8ohm Nautilus coils, you’ll find the 0.7ohmn variants work as well, though we recommend sticking to 50/50 or high-PG e-liquid. The Nautilus coil series is one of the most widespread around, and you’ll likely never enter a vape store that doesn’t stock them as they’re compatible with a number of Aspire tanks.

What are the K3 tank's special features?

The Aspire K3 is designed with simplicity in mind. It doesn’t feature complex top fill sliding latch mechanisms or multiple airflow settings to memorise; it’s a basic and appropriately priced starter tank, designed to produce a moderate amount of MTL vapour without any complications or need for tools. Those seeking a more sophisticated tank that utilises the same coils may wish to look into the Nautilus Mini or Nautilus 2S, which feature extra functions such as airflow control, leak proofing and steel peripherals for increased tank durability.

Does the K3 tank come as part of a kit?

The Aspire K3 is a standalone tank that can fit on any mod or battery with a 510 thread connection, which is the vast majority. There’s no need to buy a whole kit just to use the K3; mods such as the Innokin Z50 and Vaporesso Tarot Nano can fully utilise the K3, and will likely provide long battery lives due to the relatively low levels of power the K3 requires to fire with the Nautilus coil system. Alternatively, the K3 tank makes a great addition when purchasing a kit for those who desire an inexpensive secondary tank.
