Warning: This content is intended for adults of legal vaping age only. Vaping products contain nicotine, which is an addictive chemical. These products are not intended for use by minors, non-smokers, pregnant or breastfeeding women, people with heart conditions, high blood pressure, or asthma. Consult a physician if you have concerns about whether vaping products are appropriate for you.
Understanding the mechanics of your specific device allows you to maintain your equipment and enjoy the full profile of your chosen e-liquid. Every vape pen has a unique design, but most follow a few standardized loading methods. By following the steps outlined below, you can ensure your device performs at its peak every time you take a puff.
Understanding Your Vape Pen Components
Before you learn how to load a vape pen, you must identify the parts that make up your device. Most vape pens consist of a battery, a heating element, and a reservoir for the liquid. Knowing these terms will help you follow the instructions provided by manufacturers and retailers like us.
The Battery (Mod)
The battery is the power source of the pen. Some pens have internal batteries that you charge via a USB port. Others use external, replaceable batteries. The battery sends power to the heating element when you press a button or, in "draw-activated" devices, when you inhale.
The Atomizer and Coil
The atomizer is the overall component where the vapor is created. Inside the atomizer is the coil. The coil is a small metal wire or mesh screen wrapped around a wicking material, which is usually organic cotton. When the battery heats the coil, the liquid in the wick turns into vapor.
The Tank or Pod
This is the reservoir that holds your e-liquid. In traditional vape pens, this is often a glass or plastic tank that screws onto the battery. In pod systems, this is a plastic cartridge that snaps or magnetically attaches to the device.
The Chimney
In most tanks, there is a central tube called the chimney. This leads from the coil to the mouthpiece. It is designed for airflow only. One of the most important rules of loading a vape pen is to never get e-liquid inside this center tube.
Preparing Your E-Liquid for Loading
Not all e-liquids are the same. Choosing the right one for your pen is just as important as how you load it. Using the wrong liquid can cause leaking or a "dry hit," which occurs when the wick is not saturated enough.
PG vs. VG Ratios
E-liquids are made of Propylene Glycol (PG) and Vegetable Glycerin (VG).
- PG (Propylene Glycol): This is a thinner liquid that carries flavor well and provides a stronger throat hit.
- VG (Vegetable Glycerin): This is a thicker liquid that produces larger, denser vapor clouds.
Small vape pens and pod systems usually work best with a 50/50 ratio or a higher PG content. Larger, sub-ohm pens require a higher VG content (70% or more) because their larger coils can handle the thicker liquid. At Vapor Authority, we carry exclusively US-made e-liquid options that use high-quality ingredients, ensuring a cleaner experience regardless of the ratio you choose.
Nicotine Types
You will generally choose between freebase nicotine and nicotine salts.
- Freebase Nicotine: Standard nicotine used in most e-juices. It is best for larger pens and lower nicotine strengths (3mg to 12mg).
- Nicotine Salts: These allow for higher nicotine concentrations (25mg to 50mg) without a harsh throat hit. These are intended only for low-power pod systems and small vape pens.
How to Load a Top-Fill Vape Pen
Top-fill tanks are currently the most popular design because they allow you to refill the device without removing the tank from the battery. This makes the process faster and reduces the risk of making a mess.
- Expose the Fill Port: Most top-fill pens use a threaded cap or a sliding top. If it is threaded, unscrew the top piece where the mouthpiece (drip tip) is located. If it is a slide-top, look for an arrow or mark indicating where to push.
- Locate the Filling Slots: Once the top is open, you will see one or two holes on the sides. You will also see the center chimney.
- Insert the E-liquid Bottle Tip: Place the tip of your e-liquid bottle into one of the side slots. Do not use the center hole.
- Fill the Tank: Gently squeeze the bottle. Watch the liquid level through the glass. Fill the tank about 90% of the way. Leaving a small air pocket helps prevent pressure issues that cause leaking.
- Seal the Tank: Screw the top cap back on or slide the lid shut. Ensure it is tight but do not over-tighten, as this can damage the rubber O-rings.
How to Load a Bottom-Fill Vape Pen
Bottom-fill designs were the industry standard for years and are still found on many classic starter kits. These require a few extra steps because you must remove the tank from the battery to access the fill port.
- Remove the Tank: Unscrew the tank from the battery. Be careful not to grip the glass too hard.
- Invert the Tank: Turn the tank upside down so the mouthpiece is pointing at the floor.
- Unscrew the Base: The base of the tank (the part that connects to the battery) usually houses the coil. Unscrew this base piece while keeping the tank inverted.
- Fill Along the Side: Just like with top-fill tanks, you must avoid the center chimney. Tilt the tank slightly and pour the e-liquid down the inside wall of the glass.
- Reassemble: Screw the base back onto the tank. Once it is secure, you can flip the tank upright and screw it back onto your battery.
How to Load a Pod System
Pod systems have simplified the loading process significantly. Most pods use a side-fill or bottom-fill method involving a small silicone stopper.
- Remove the Pod: Pull the pod out of the battery section. Most pods are held in place by magnets.
- Open the Silicone Plug: Look for a small rubber or silicone flap on the side or bottom of the pod. Use your fingernail to lift the edge and move it out of the way.
- Fill the Pod: Insert the nozzle of your e-liquid bottle into the hole. Because pods are small, air bubbles can sometimes block the liquid. If this happens, tap the pod gently to move the bubble.
- Close the Plug: Push the silicone stopper back into the hole firmly. Make sure it is completely flush with the pod to prevent leaking.
- Wipe Excess Liquid: Use a paper towel to wipe any stray drops of liquid from the outside of the pod before putting it back into the battery.
The Importance of Priming Your Coil
One of the most common mistakes when loading a vape pen is trying to use it immediately after filling. If the cotton wick inside the coil is dry when you heat it up, it will burn instantly. A burnt wick cannot be fixed; you will have to throw the coil away and start over.
To prevent this, you must "prime" the coil. If you are installing a brand-new coil, put 3 to 5 drops of e-liquid directly onto the exposed cotton on the sides and top of the coil before you put it into the tank. Once the tank is filled, let it sit for at least 10 minutes. This allows the liquid to fully saturate the center of the wick. This patience ensures your coil lasts longer and delivers better flavor.
Battery Safety for Vape Pens
While many vape pens use internal batteries, some larger "pro" style pens use external 18650 or 21700 batteries. Proper battery handling is essential for your safety and the longevity of your device.
Inspect Your Wraps
If you use a pen with a removable battery, always check the plastic wrap. If there is a tear or a nick in the wrap, do not use the battery. A damaged wrap can cause a short circuit.
Use the Correct Charger
Always use the charging cable that came with your device. Avoid using "fast-charging" wall blocks intended for tablets or laptops, as these can provide too much current and overheat the battery.
Storage and Transport
Never carry loose batteries in your pocket or bag. They can come into contact with keys or coins, leading to a thermal event. Always use a plastic battery case. Additionally, do not leave your vape pen in a hot car, as extreme temperatures can damage the battery chemistry.
Maintenance and Cleaning Tips
Loading your vape pen is also the perfect time to perform a little maintenance. A clean device lasts longer and tastes better.
- Clean the Connections: Use a cotton swab and a tiny bit of rubbing alcohol to clean the "510 connection" (the threads where the tank meets the battery). This ensures a solid electrical connection.
- Rinse the Tank: If you are changing flavors, it is a good idea to rinse the tank with warm water. Remove the coil first, as you should never get the coil wet with water. Let the tank dry completely before refilling.
- Check the Seals: Look at the rubber O-rings. If they look flattened or torn, replace them using the spares usually included in your kit.
Troubleshooting Common Loading Issues
Even if you follow every step, you might encounter a few minor issues. Most of these have simple fixes.
Why is my vape pen gurgling?
Gurgling usually means there is e-liquid trapped in the center chimney. To fix this, wrap a paper towel around the mouthpiece and blow gently through it. This will force the excess liquid out of the airflow vents.
Why is my tank leaking from the bottom?
Leaking often happens because of a pressure imbalance. Ensure your top cap is screwed on straight. If you leave your vape pen in a hot environment, the liquid will thin out and may leak through the airflow holes. Always store your device upright and in a cool place.
Why does my new coil taste burnt?
If you primed your coil and it still tastes burnt, your wattage might be too high. Check the side of your coil for the "recommended wattage" range. Start at the lowest number and gradually move up until you find your preferred setting.

FAQ
How long should I wait after filling a new vape pen?
You should wait at least 10 minutes after the first fill to allow the e-liquid to fully saturate the cotton wick. This process, known as priming, prevents the coil from burning when you first activate the battery. Taking a few "dry pulls" (inhaling without pressing the power button) can also help pull liquid into the wick.
Why is e-liquid coming out of the mouthpiece when I inhale?
This is usually caused by "flooding," where too much liquid has entered the coil or the center chimney. It can happen if you accidentally pour liquid into the center tube during refilling or if the device has been sitting on its side. Clean the chimney with a twisted paper towel to resolve the issue.
Can I change e-liquid flavors without changing the coil?
Yes, you can change flavors, but the old flavor will linger for the first several puffs. For the best results, wait until your tank is nearly empty before adding the new flavor. If you are switching between very different profiles, such as menthol to dessert, you may want to use a fresh coil to avoid an unpleasant taste.
How full should I fill my vape tank or pod?
It is best to fill your tank or pod to about 90% capacity. Leaving a small pocket of air at the top helps maintain the vacuum seal inside the tank. If you fill it to the very brim, the pressure from replacing the cap can force liquid into the coil and cause leaking or gurgling.
