2ml Pyrex Glass Tank
The main tank houses the central chimney and juice reservoir, enclosed in Pyrex glass. It can store up to 2ml of e-juice which should last around three days. Since the glass exterior is part of the tank and cannot be disassembled, it can be quite challenging to wash and clean.
1.8 ohm Bottom Vertical Coil (BVC)
Unlike the K2 tank that comes with the older 1.6Ω Aspire ET-S BVC coil, the K3 tank uses a 1.8 ohm Aspire Nautilus BVC coil which is designed to last longer while creating the purest and cleanest flavors. Nautilus coils are very popular so you can easily find a replacement for your K3 atomizer when it wears out. Aspire Nautilus coils are made of Kanthal wire vertically arranged with organic cotton wicks for premium flavors.
Fixed Airflow Holes
Around the base of the tank features four fixed air holes. Although you cannot adjust the size of the holes (like in higher end tanks), the draw is perfect for first-time vapers who are used to the sensation of pulling from a combustible cigarette.
