This guide provides step-by-step instructions for filling various types of devices while avoiding common pitfalls like leaking or burnt coils. Whether you are using a compact pod system starter kit or a sophisticated box mod, the following techniques will help you maintain your device with confidence. (vaporauthority.com)
Introduction
Modern vaping hardware comes in many shapes and sizes, and the method for adding e-liquid varies significantly between models. Most beginners start with simple pod systems, while experienced enthusiasts often prefer large sub-ohm tanks. Regardless of the hardware, the goal remains the same: getting the e-liquid into the reservoir without getting it into the central airflow tube or overfilling the chamber. Proper filling technique also involves "priming" your equipment, which is a vital step for any new coil or pod. (vaporauthority.com)
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.
At Vapor Authority, we only carry 100% authentic hardware and US-made e-liquids, ensuring that your filling experience is as consistent as possible. By following a few standard procedures, you can prevent common issues such as "spit-back" (when hot juice jumps into your mouth) or "dry hits" (when the cotton wick burns due to lack of liquid). Understanding the mechanics of your specific tank or pod is the first step toward a hassle-free experience. (vaporauthority.com)
Understanding Your Hardware
Before you open your bottle of e-liquid, you must identify what type of filling system your device uses. Most hardware falls into three main categories: top-fill tanks, bottom-fill tanks, and pod systems. Each has a specific port designed to accept the "needle-nose" tip of a standard e-juice bottle. (vaporauthority.com)
Top-Fill Tanks
Top-fill designs are the most common in modern sub-ohm tanks. These allow you to add liquid without removing the tank from your mod. They usually feature a sliding top cap, a swivel hinge, or a threaded cap that unscrews to reveal the filling ports. This design is preferred because it minimizes the mess and makes it easy to top off your liquid on the go. (vaporauthority.com)
Bottom-Fill Tanks
While less common today, many classic tanks and some budget-friendly starter kits use a bottom-fill design. To fill these, you must unscrew the tank from the battery, turn it upside down, and unscrew the base. While this takes an extra step, these tanks are often very reliable and less prone to leaking from the top. (vaporauthority.com)
Open Pod Systems
Pod systems are compact devices that use a plastic pod instead of a glass tank. "Open" pod systems are designed to be refilled several times before the entire pod or the internal coil is discarded. These usually feature a small rubber plug on the side or bottom of the pod that you pull back to reveal the filling hole. (vaporauthority.com)
Essential Definitions for New Vapers
To follow these instructions, it helps to understand a few industry terms:
- Coil / Atomizer Head: The heating element inside your tank or pod that turns liquid into vapor. It contains a metal heating wire and a cotton wick.
- Wick: The material (usually organic cotton) that absorbs the e-liquid and brings it to the heating coil.
- Priming: The process of manually soaking the cotton wick with e-liquid before using a new coil for the first time.
- Sub-Ohm: A type of vaping that uses coils with a resistance of less than 1.0 ohm. This typically requires higher wattage and produces more vapor.
- MTL (Mouth-to-Lung): A style of vaping that mimics the draw of a traditional cigarette, where vapor is pulled into the mouth first and then inhaled.
- DTL (Direct-to-Lung): A style of vaping where the vapor is inhaled directly into the lungs, similar to taking a deep breath.
How to Prepare and Prime a New Coil
The most important step in putting juice in a vape occurs before you even fill the tank. If you install a new coil and immediately start vaping, the dry cotton will burn instantly. Once a wick is scorched, the burnt taste will never go away, and you will have to throw the coil away. (vaporauthority.com)
- Remove the new coil from its packaging.
- Apply liquid to the "wicking ports." These are the small holes on the side of the metal coil housing where you can see the white cotton.
- Drip a few drops into the top. Look down through the center of the coil and put 2–3 drops directly onto the cotton inside.
- Install the coil. Screw or press it firmly into the base of your tank or pod.
- Wait. After filling the tank, let it sit for at least 5 to 10 minutes. This ensures the liquid has fully saturated the center of the wick.
Step-by-Step: Filling a Top-Fill Sub-Ohm Tank
Most high-performance tanks, such as those made by GeekVape or Uwell, utilize a top-fill system. These are designed for convenience, but you must be careful not to pour liquid down the center hole. (vaporauthority.com)
Step 1: Open the Top Cap
Depending on your model, you will either slide the top piece back (often marked with a small arrow), press a button to swing it open, or unscrew the top cap entirely.
Step 2: Locate the Filling Port
Once open, you will see at least two holes. One is the large center hole (the chimney or airway). Do not put juice in the center hole. This leads directly to the mouthpiece and will cause the device to leak or spit juice into your mouth. Look for the curved or circular slot on the side.
Step 3: Insert the Bottle Tip
Place the tip of your e-liquid bottle into the side filling port. Squeeze gently. Watch the juice level through the glass.
Step 4: Leave a Small Air Gap
Do not fill the tank to the absolute brim. Leave a small pocket of air at the top. This air pocket helps maintain the vacuum pressure inside the tank, which prevents the liquid from being forced out through the airflow vents at the bottom.
Step 5: Close and Secure
Slide or screw the cap back into place. Ensure it is tight to prevent leaks. If your tank has adjustable airflow, it is often helpful to close the airflow vents while filling to further prevent leaking.
Step-by-Step: Refilling a Pod System
Pod systems, like those from Vaporesso or SMOK, are slightly different because the pods are usually made of tinted plastic. The process is still straightforward once you know where the fill plug is. (vaporauthority.com)
- Remove the Pod: Pull the pod out of the battery housing. Most are held in place by magnets.
- Find the Plug: Look for a silicone or rubber plug. It is usually black, red, or blue.
- Lift the Tab: Use your fingernail to gently lift the edge of the plug. It will usually stay attached to the pod at one end so you don't lose it.
- Fill the Pod: Insert the bottle tip into the hole. Because pods are small, air bubbles can sometimes block the liquid. Tilt the pod slightly to help the liquid flow to the bottom.
- Seal it Tight: Press the rubber plug back in firmly. Ensure it is completely flush with the pod surface.
- Wipe Excess: If any juice spilled on the outside of the pod, wipe it off with a paper towel before putting it back into the battery. This protects the internal electronics.
Choosing the Right E-Liquid for Your Device
At Vapor Authority, we carry a vast selection of US-made e-liquids, but they are not all interchangeable. Using the wrong "thickness" of juice can make filling difficult and lead to performance issues. (vaporauthority.com)
PG vs. VG Ratios
E-liquid consists of Propylene Glycol (PG) and Vegetable Glycerin (VG).
- High VG (70% or more): This liquid is thick and creates large clouds. It is intended for sub-ohm tanks with large wicking ports.
- 50/50 PG/VG: This liquid is thinner and flows more easily. It is perfect for small pod systems and MTL tanks.
If you put thick, high-VG juice into a tiny pod, the wick won't be able to absorb it fast enough, leading to a burnt taste. Conversely, if you put thin juice into a high-powered sub-ohm tank, it may flow too quickly and leak out of the airflow holes.
Nicotine Types
- Freebase Nicotine: Standard nicotine used in most larger bottles (3mg, 6mg, 12mg).
- Nicotine Salts: Formulated to be smoother at higher strengths (25mg to 50mg). These should generally only be used in low-wattage pod systems.
Troubleshooting Common Filling Problems
Even if you know how to put the juice in a vape, you might encounter a few hiccups. Here is how to handle them.
Leaking from the Airflow
If juice is pouring out of the bottom of your tank, you likely have a pressure issue. Ensure your top cap is screwed on straight and the O-rings (rubber seals) are not broken. Also, ensure you aren't leaving the top cap off for too long; the longer the tank is open, the more pressure it loses, allowing juice to escape. (vaporauthority.com)
Gurgling or "Spitting"
This happens when the coil is "flooded," meaning there is too much juice in the center of the heating element. To fix this, take a paper towel, hold it over the mouthpiece, and flick the device downward toward the floor a few times. This forces the excess liquid out. You can also turn up the wattage slightly to vaporize the extra juice.
Air Bubbles Blocking the Port
In small pods, a bubble can form at the fill hole, preventing juice from going in. If this happens, do not keep squeezing the bottle, or you will make a mess. Pull the bottle out, tap the pod against your palm to dislodge the bubble, and try again.
Essential Battery Safety for Vapers
If your device uses external batteries (like 18650 or 21700 cells), safety is paramount. Most devices used for sub-ohm vaping require these powerful batteries. (vaporauthority.com)
- Check the Wraps: Always inspect the plastic coating on your batteries. If there is a tear or a nick, do not use the battery. A damaged wrap can cause a short circuit.
- Use a Dedicated Charger: While many mods allow for USB charging, it is always safer and better for the longevity of your batteries to use an external charger.
- Store Properly: Never carry loose batteries in your pocket or bag. If they touch keys or coins, they can vent. Use a plastic battery case.
- Avoid Extreme Heat: Do not leave your vape or batteries in a hot car. High temperatures can cause battery failure or degradation.
Maintenance and Care
To keep your device working perfectly, we recommend a quick cleaning every time you change your coil. When the tank is empty, rinse the glass and metal parts (but not the coil!) under warm water. Dry them completely before reassembling. This prevents old flavor residue from "ghosting" into your new juice. (vaporauthority.com)
When storing your e-liquid, keep it in a cool, dark place. Heat and sunlight can degrade the nicotine and darken the color of the juice, which may alter the flavor profile over time. Always keep e-liquids out of reach of children and pets, as nicotine is toxic if ingested. (vaporauthority.com)
Conclusion
Filling your vape is a simple task, but doing it correctly ensures a much better experience. Remember to always prime your coils, choose the right PG/VG ratio for your hardware, and leave a small air gap at the top of your tank to prevent leaking.
- Always prime new coils for 5–10 minutes before use.
- Identify whether your device is top-fill, bottom-fill, or a pod system.
- Avoid getting e-liquid into the center airflow tube.

FAQ
Why does my vape taste burnt even though I just filled it?
A burnt taste usually happens because the coil was not "primed" before use. If you don't let the liquid soak into the cotton wick for at least 5–10 minutes, the dry cotton will burn when heated. Once the cotton is scorched, you must replace the coil to get rid of the burnt flavor. (vaporauthority.com)
Can I put any e-liquid in any vape?
Not exactly. High-wattage sub-ohm tanks require thicker, high-VG e-liquids to prevent leaking. Small, low-power pod systems work best with thinner 50/50 PG/VG liquids or nicotine salts. Using the wrong liquid can lead to leaking or "dry hits" where the coil cannot absorb the juice fast enough. (vaporauthority.com)
How often should I refill my tank?
You should refill your tank or pod before the e-liquid level falls below the visible wicking ports on the side of the coil. If the juice level is too low, the cotton cannot stay saturated, which will lead to a burnt coil. It is best to keep your tank at least one-quarter full at all times. (vaporauthority.com)
What should I do if I get juice in the center hole?
If you accidentally pour liquid into the center airflow tube, the device will likely gurgle or leak. To fix this, remove the tank from the battery, hold a paper towel over the mouthpiece, and blow firmly through the mouthpiece. This will force the excess juice out through the airflow vents at the bottom. (vaporauthority.com)
