What Is a Refillable Vape?
A refillable vape, also called an open pod system, is an all-in-one vaping device built around a refillable pod instead of a sealed, pre-filled device. Instead of being locked into whatever flavour or nicotine strength came in the box, you fill the refillable pod yourself with the e-liquid of your choice, freebase or nicotine salt, and you're ready to vape.
That flexibility is the whole appeal. You're not tied to one brand's flavour lineup or strength options. You can fine-tune nicotine strength, switch flavours on the fly, and adjust your setup as your preferences change, all without buying a new device. Open pod systems like the Uwell Caliburn G3 Pro (paired with G3 pods) pair that flexibility with strong flavour performance in a compact, pocket-friendly build.
For vapers who want a no-fuss, pre-filled alternative, our closed pod systems are worth a look instead.
If you want a vape device that offers flexibility, portability, and simple daily use, an open pod system is a practical choice.)
Key Attributes and Their Explanation
Pod capacity: Most open pod vapes hold 2–5 mL of e-liquid. A larger capacity means fewer refills throughout the day, useful if you vape often or don't want to carry a vape juice bottle with you.
Coil resistance: High-resistance coils (above 1.0 ohm) suit MTL vaping and nicotine salts, giving a smoother, more restricted draw. Low-resistance coils (below 1.0 ohm) suit RDL vaping, producing more vapour and stronger flavour.
Wattage: Fixed-wattage pods are simpler and harder to get wrong, good for beginners. Variable-wattage pods let you fine-tune vapour production and flavour intensity to match the coil you're using.
Battery: Most open pod devices run 1–2 days per charge, depending on usage and screen presence. USB-C fast charging is now standard on most current devices, cutting downtime between charges.
Display: Some pods are screenless for a simpler, smaller build. Others include a small screen showing wattage, puff count, or battery level, useful if you like to track or adjust your settings.
Activation: Draw-activated devices fire automatically when you inhale, closer to a cigarette-like experience. Button-fire devices require a press to activate, giving more control over when vapour is produced.
Airflow control: Adjustable airflow lets you switch between a tighter MTL draw and a looser RDL draw on the same device, instead of needing two separate pods.
E-liquid compatibility: Most open pod systems support both freebase nicotine and nicotine salt e-liquids, but coil resistance affects which one performs best. Check your device's spec sheet before buying e-liquid.
Popular Flavour Categories
- Classic: Tobacco, Menthol
- Fruity: Mango, Berry, Apple
- Dessert: Vanilla, Custard, Chocolate
- Beverage: Cola, Coffee, Energy Drink
Since open pod systems refill in seconds, switching between these categories costs you nothing but a quick rinse and refill.
MTL vs. RDL: Choosing Your Draw Style
- MTL (Mouth-to-Lung): A tighter draw similar to smoking, best with nicotine salts, ideal for smokers transitioning to vaping
- RDL (Restricted Direct Lung): A looser draw, more vapour, and stronger flavour delivery
Devices like the Vaporesso series offer adjustable airflow and multiple pod resistances, so you can switch between MTL and RDL without switching devices.
Why Choose a Refillable Vape Over a Disposable or Closed Pod
- Full control over nicotine and flavour: choose your own e-liquid and strength, not a fixed pre-filled option
- Lower cost over time: refilling with bottled e-liquid costs less than repeatedly buying pre-filled pods or disposables
- Wider flavour selection: access to the full e-liquid market, not one brand's limited lineup
- Less waste: reusable pods and devices generate less waste than single-use disposables
- Works for beginners and experienced vapers: simple enough to start with, flexible enough to grow into
How To Use A Refillable Pod System?
- Fill the pod. Open the fill port (top or side) and add your e-liquid, freebase or nicotine salt, depending on your coil. Avoid overfilling.
- Insert the pod. Click or snap it into the device; most are magnetic or click-fit.
- Prime the coil. Let a new pod sit 5–10 minutes before vaping so the wick fully saturates. This prevents burnt hits.
- Vape. Draw-activated devices fire on inhale; others use a button. Adjust airflow for your preferred MTL or RDL style.
- Replace as needed. Swap the coil or pod when flavour drops, or taste turns burnt, depending on whether your device uses a plug-and-play coil or an integrated pod.
Pro tip for vapers: Always use e-liquids that comply with local regulations to ensure safety and optimal performance.
What to Look for When Buying an Open Pod Vape
When purchasing an open pod system in Canada, consider the following:
- Battery capacity: Important for ensuring your vape pens last throughout the day without needing constant recharging. Larger batteries mean fewer charges, enhancing convenience.
- USB-C fast charging: A must for daily use, especially for those who prefer the flexibility of pod vaping.
- Pod compatibility: Wider compatibility = better flexibility
- Leak-resistant design: Especially important for colder climates
- Airflow control: Helps customize draw style
Selecting the ideal open pod kit upfront ensures better performance and long-term satisfaction with your refillable pod system, designed for ease of use. Check for the starter kit if you are new to this.
Maintenance and Safety
Coil and pod care
- Prime new coils for 5–10 minutes before first use
- Keep e-liquid above the coil's wick ports to avoid dry hits
- Replace coils every 1–2 weeks, depending on use and e-liquid sweetness
- Wipe the pod and mouthpiece weekly with a damp cotton swab
- Rinse with warm water and dry 12–24 hours before switching flavours
Device care
- Keep battery contacts dry; wipe down every few days
- Clear the charging port of lint or debris periodically
- Store the device upright to prevent leaks
- Fill to the max line, not past it, to avoid pressure buildup
- Keep devices away from direct sunlight and extreme heat
- Use a 50/50 PG/VG e-liquid blend unless your device specifies otherwise
Battery safety
- Use only the manufacturer-supplied charger
- Unplug once fully charged
- Avoid letting the battery fully deplete
- Stop using and replace if you notice swelling, damage, or excess heat
Troubleshooting
- Gurgling: remove the pod and gently blow through the mouthpiece to clear excess liquid
- Burnt taste: prime longer if it's a new pod; replace the coil if it persists after cleaning
- No firing: clean the contact points and check the device isn't locked
