To use a vape pen kit, start by fully charging the device. Fill the tank or pod with your preferred e-liquid and allow it to sit for a few minutes so the coil can soak the liquid. Once ready, press the power button (or inhale if it's draw-activated) and enjoy your vape. Always refer to the user manual for specific instructions for your device.

The frequency of coil replacement depends on your usage and the type of e-liquid you use. Generally, coils should be replaced every 1-2 weeks or when you notice a burnt taste or a significant drop in vapor production.

Vape pen kits typically perform well with 50/50 VG/PG e-liquids or high PG (propylene glycol) blends, which provide a good balance of flavor and throat hit. Always check your device’s specifications for optimal e-liquid compatibility.
