Maintenance and Care

Avoid dry hits: Make sure the cotton is well saturated before first use. For MTL styles, keep the appropriate e-liquid ratio.
When swapping airflow pins, handle them carefully to avoid damaging threads or seals.
Regularly clean the 510 thread and the interior of the chimney to prevent condensation on the Drip Tip.
We recommend 50%VG / 50%PG liquids for MTL uses (pins from 1.0 to 1.8mm) and 70%VG / 30%PG for RDL and DL configurations (pins from 2.2 to 4.0mm). Try different Liquids ou Concentrates .

Vaping Styles and Coils

The Sparrow RTA stands out for supporting three distinct vaping styles in the same atomizer:

MTL (Mouth to Lung): Closed draw identical to traditional cigarette. Ideal for high nicotine or nicotine salts. Use the 1.0mm to 1.8mm pins with the MTL mouthpiece.
RDL (Restricted Direct Lung): Intermediate draw with concentrated flavour and moderate vapor. Use the 2.2mm to 2.8mm pins.
DTL (Direct To Lung): Open draw for maximum vapor production. Use the 3.4mm to 4.0mm pins with the DL mouthpiece.

Tip: First adjust the inner air pin to set the basic restriction and use the upper airflow ring to fine-tune.

We have a variety of ready-made coils, wires, cottons e tools to help you create your ideal vape, from basic to advanced.
