Creating your own refillable vape penjuice is an exciting venture for many vapers, refillable vape pen offering not only a cost-effective solution but also the opportunity to experiment with unique flavor combinations. This guide will walk you through the basics of DIY refillable vape penjuice, including the tools, ingredients, and simple steps needed to start your mixing journey.

Understanding the Ingredients

The process of making refillable vape penjuice requires a few key ingredients:

  • Propylene Glycol (PG): This is a carrier fluid that ensures the nicotine and flavors are well-dissolved. It provides a stronger throat hit and is thinner in consistency.
  • Vegetable Glycerin (VG): VG is thicker than PG and is known for producing more vapor. It has a slightly sweet taste and provides a smoother hit.
  • Nicotine: This is optional and can be adjusted according to your preference. Nicotine comes in liquid form and varies in strength.
  • Flavor Concentrates: These are specifically made for vaping. Never use food flavoring as it may contain oils that are harmful when inhaled.

Tools You Will Need

  • Syringes or Droppers: For precise measurement of each ingredient.
  • Gloves: To protect your hands, especially when handling nicotine.
  • Empty Bottles: For mixing and storing your creations.
  • Labels: To mark your mixes with their flavor, PG/VG ratio, nicotine strength, and the date it was made.
  • A Clean Work Area: Ensure your mixing area is clean and well-organized.

Basic Steps to Make Your Own refillable vape penJuice

  1. Prepare Your Work Area: Clean your work surface and gather all the necessary supplies. Wearing gloves during the process is recommended, especially when handling nicotine.
  2. Measure the Nicotine: If you are using nicotine, measure the desired amount carefully with a syringe and transfer it to your mixing bottle. Always start with the nicotine to avoid cross-contamination.
  3. Add Propylene Glycol: Add the desired amount of PG to the nicotine. This helps dissolve the nicotine and flavor concentrates thoroughly.
  4. Add Flavor Concentrates: Add your chosen flavors. Typically, flavor should make up 10-20% of the total volume of your e-liquid, depending on how intense you want the flavor. It’s best to start lower and adjust based on taste.
  5. Add Vegetable Glycerin: Fill the remainder of your bottle with VG. VG is thick, so it may be easier to handle with a larger syringe or to pour carefully if your container allows.
  6. Shake the Mixture: Once all ingredients are in the bottle, cap it tightly and shake vigorously for several minutes to ensure everything is well mixed. The color of the liquid may change, and bubbles will likely form.
  7. Steep Your refillable vape penJuice: Steeping allows the flavors to blend and mature, enhancing the taste of your e-liquid. Store your bottles in a cool, dark place and give them a gentle shake occasionally. Steeping can take from a few days to several weeks.
  8. Test and Adjust: After steeping, try your refillable vape penjuice to see if it meets your expectations. Adjust if necessary by adding more flavor, PG, or VG.

Safety Tips

  • Handle nicotine with care: Nicotine is a toxic substance and should be handled with utmost care. Use gloves and work in a well-ventilated area.
  • Proper storage: Keep your nicotine and flavor concentrates away from children and pets.


Making your own refillable vape penjuice can be a rewarding experience that offers endless customization in flavors and strengths. By following these steps and adhering to safety guidelines, you can enjoy high-quality, personalized refillable vape penjuice at a fraction of the cost.
