Maintenance and Care

Avoid dry hits: happens when the cotton is dry, causing a burnt taste; keep liquid in the tank to prevent.
Regularly clean the battery contacts, connections and tank to prevent dirt buildup and flavour loss.
Fine-tune the airflow and power to avoid dry hits and extend coil life.
Avoid prolonged exposure to water, dust or drops - although rugged, it still requires basic care.
Store the device in a dry place away from extreme temperatures.
Keep liquids in a cool place away from children and pets. Use high-quality liquids from reliable brands to preserve flavour and prevent tank damage, try different ones. Liquids or Concentrations to vary the flavour and avoid the "vaper's tongue", which occurs when the palate becomes used to the same flavour. We recommend liquids 70% VG / 30% PG for coils below 0.6 ohm, and 50% VG / 50% PG for coils above 0.6 ohm.

Vaping Styles and Coils

The Bonza Pro RTA offers excellent versatility for different vaping styles, depending on the coil and configuration chosen:

RDL (Restricted Direct Lung): Airflow more closed, vapor moderate with full-bodied flavour. (Ex.: 0.45Ω)
DL (Direct Lung): Airflow open for abundant vapor production and intense flavour. (Ex.: 0.30Ω)
Dual Coil: For those seeking even denser vapor and faster response — ideal with higher powers.

Tip: Choose the coil and style according to the result you want: RDL for more defined flavour and moderate consumption, DL for robust clouds, and Dual Coil for maximum power and vapor. Using quality cotton and wires greatly improves overall performance.

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