Maintenance and Care

Avoid dry hits: It 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 durable, it still requires basic care.
Store the device in a dry place and away from extreme temperatures.
Keep liquids in a cool place and out of reach of children and animals. Use high-quality liquids from reliable brands to preserve flavour and prevent damage to the tank, try different Liquids or Concentrates to vary the flavour and avoid the "vaper's tongue", which occurs when the palate becomes accustomed 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.

Vapour Styles and Coils

The SXK By-Ka V11 is an atomizer focused on MTL (mouth to lung), offering different levels of restriction through air pins:

MTL (Mouth to Lung) : Draws vapor to the mouth before inhaling, similar to smoking a "bad-smelling". Ideal for those seeking intense flavour and reduced liquid consumption. (Ex.: 1.2Ω) .
RDL (Restricted Direct Lung): Draw vapor directly to the lungs, but with a tighter air flow, offering full-bodied flavour and moderate vapor. (Ex.: 0.8Ω / 0.4Ω).
DTL (Direct To Lung): Draw vapor directly to the lungs with an open air flow, producing dense clouds and strong flavour. (Ex.: 0.3Ω / 0.2Ω).

Tip: choose the coil according to the style you like most. MTL favors flavour and discreteness, RDL balances clouds and flavour, while DTL provides maximum vapor production. You can also build your own coils with special wires, choosing the thickness and type to adjust the vapor and flavour to your preference. In addition, using quality cotton is essential for good performance and durability.

We have a variety of coils prontas, fios, cotton pads e ferramentas to help you create your ideal vape, from basics to advanced.
