Here’s a straightforward guide to properly using a 7s electronic cigarette as a beginner:
1. Charge the Device Fully
Connect the included USB cable to the device’s charging port and a standard power source (e.g., computer port, USB adapter). The indicator light will signal charging; it typically turns green or switches off when charging is complete. Avoid using the device while charging and never leave it unattended.

2. Prime the Coil
Unscrew the mouthpiece/tank from the battery. Locate the coil head inside the tank. Add a few drops of e-liquid directly onto the exposed cotton wicking material inside the coil. Reassemble the tank and let it sit upright for 5-10 minutes. This saturates the wick, preventing immediate burning (“dry hits”).
3. Fill the Tank
- Detach the mouthpiece or slide open the fill port (refer to device design).
- Carefully fill the tank with your chosen e-liquid.
- Avoid overfilling – leave a small air gap near the top.
- Ensure the fill port is completely closed before reassembling.
4. Activate and Inhale
Most 7s devices operate via automatic draw activation. Simply inhale gently but steadily through the mouthpiece; the device will automatically power the coil. Take slow, mouth-to-lung puffs similar to smoking a cigarette. Avoid forceful or extremely long draws, especially as a beginner.
5. Maintain and Store Safely
- Keep the device upright to prevent e-liquid leaks.
- Replace the coil every 1-2 weeks or when flavour diminishes or tastes burnt.
- Regularly clean the connection between the tank and battery with a tissue to ensure good contact.
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
