All Caliburn G Models – Canada 2026 Specs and Prices

All prices are DoorVapes prices as of June 2026.

What Is the Uwell Caliburn G Series?

The Caliburn G series is Uwell’s open pod system lineup built around the GPP (Grade Precision Pod) coil platform. Unlike closed pod systems, every Caliburn G device uses replaceable coils inside refillable pods. You fill the pod with any nicotine salt or freebase e-liquid, replace the coil when flavour drops, and keep the device indefinitely.

According to Statistics Canada, approximately 13% of Canadian adults aged 20 to 34 currently use vaping products. The Caliburn G series is one of the most recommended device lines for adult smokers making the switch from cigarettes due to its consistent flavour delivery, simple operation, and cross-compatible pod platform.

Caliburn G4 vs G5 – What Actually Changed

This is the most searched comparison in the lineup. Here is the direct answer.

The G4 introduced the animated OLED screen, PRO-FOCS 4.0 flavour technology, and 5–35W adjustable wattage with Storm and Wave power modes. The G4 Kit battery sits at 1300mAh. And the G4 Pro goes further with an 1800mAh battery and Uwell’s first touchscreen interface.

The G5 made one significant change battery size across the board. The G5 Lite packs a 1600mAh battery at $25.99, which is less than the G4 Kit. It also runs at 35W with PRO-FOCS 4.0 and dual adjustable airflow. The G5 introduced GPP Alpha Edition pods with a softer rubberized mouthpiece and improved wicking for longer coil life.

The critical point for existing Caliburn users is pod compatibility. Both generations share the GPP pod ecosystem. If you own a G4 and upgrade to a G5, your existing G4 GPP pods work in the G5 device without any changes.

Choose G4 Kit if you want the animated OLED screen and Storm/Wave power modes in a well-balanced daily device.

Choose G4 Pro if you want the largest battery in the G4 generation (1800mAh) and a touchscreen interface.

OR Choose G5 Lite if battery life is the priority and you want 1600mAh and 35W output at the lowest price in the lineup.

Caliburn G3 vs G4 – Which Generation Is Better

The G3 generation is not obsolete. The G3 Pro at $58.99 offers something neither the G4 nor G5 provides in a comparable form stepless airflow control alongside a full LCD screen. If fine-tuning your draw is a priority, no other Caliburn G device gives you that level of control.

For most vapers the G4 Kit at $40.99 is the better buy over any G3 model. It has a larger battery than the G3 Pro (1300mAh vs 1000mAh), the newer PRO-FOCS 4.0 flavour system, and the animated OLED display at a lower price.

The G3 Lite at $22.99 remains relevant as the draw-activated no-screen option with the largest battery in the budget tier 1200mAh at that price is competitive.

Which Caliburn G Device Should You Buy in Canada

Best overall – Caliburn G4 Kit ($40.99)

The G4 Kit balances battery, wattage control, display quality, and price better than any other model in the lineup. The 1300mAh battery handles a full day of regular use. The 5–35W range with Storm and Wave modes, four-stage adjustable airflow, and animated OLED screen make it the most complete package at this price. This is the device to buy if you want one Caliburn G that does everything well.

Best battery life – Caliburn G5 Lite ($25.99)

The G5 Lite is not a budget device despite its price. A 1600mAh battery, 35W output, PRO-FOCS 4.0 flavour technology, and dual adjustable airflow in a slim draw-activated body at $25.99 is the strongest value in the entire Caliburn G lineup. If you want long battery life without paying for a screen, this is the right choice.

Best advanced G4 – Caliburn G4 Pro ($48.99)

The G4 Pro has the largest battery in the G4 generation at 1800mAh and the only touchscreen in the Caliburn G lineup. The 2.51″ shatterproof display gives one-tap access to wattage, UI themes, puff data, and vape modes. It is the right choice for vapers who want the most control and the longest battery in the G4 family.

Best compact square – Caliburn G5 Lite Koko ($26.99)

The Koko form factor suits vapers who prefer a wider, palm-friendly grip over a slim stick. Identical specs to the G5 Lite with the square body design. The best compact option if the standard vertical devices do not suit your preference.

Best for maximum control – Caliburn G3 Pro ($58.99)

The G3 Pro has stepless airflow meaning you can fine-tune the draw to any point between fully closed MTL and fully open RDL. No other Caliburn G device offers this. The full LCD screen shows power, battery, resistance, and puff count. The 1000mAh battery is the weakest spec at this price but the charging speed compensates full charge in under 40 minutes via USB-C.

Best budget draw-only – Caliburn G3 Lite ($22.99)

The G3 Lite strips away the screen, the button, and the complexity. What remains is a 1200mAh draw-activated pod device at $22.99. The largest battery at the lowest price point in the entire G series.

Caliburn G Pods – Which Pods Work With Which Devices

All Caliburn G series devices use the GPP pod platform. This is the most important thing to understand before buying.

GPP pods are cross-compatible across the G3, G4, and G5 generations. If you upgrade from a G3 to a G4 or a G5, your existing GPP pods continue to work in the new device. You do not need to replace your pod stock when switching generations.

The G5 introduced GPP Alpha Edition pods with a softer rubberized mouthpiece and redesigned wicking holes for longer coil saturation and extended coil life. Alpha Edition pods work in G4 and G3 devices as well.

Available coil resistances cover MTL and RDL vaping styles. For vapers switching from cigarettes, higher resistance pods (0.9Ω–1.2Ω) produce the tightest draw closest to a cigarette. Lower resistance pods (0.4Ω–0.6Ω) suit vapers who prefer a more open draw with more vapour.

Nicotine salt e-liquids in the 10–20mg/mL range pair best with Caliburn G devices due to the low-wattage, controlled draw style.

How to Use a Caliburn G Series Device

Powering on and off
Press the fire button 5 times quickly to turn the device on or off. Devices with no button (G3 Lite, G4 Mini, G5 Lite) are always on when a pod is inserted.

Filling the pod
Open the side-fill port rubber seal. Insert your e-liquid nozzle into the fill hole not the centre airflow hole. Fill to approximately 90% capacity. For a new pod or new coil, wait 5 to 10 minutes before vaping to allow the cotton to fully saturate. Skipping this step causes dry hits and burns the coil prematurely.

Adjusting airflow
On basic models, remove the pod, rotate it 180 degrees, and reinsert to switch between tighter and more open draws. On the G4 Kit, use the side airflow slider. On the G3 Pro, use the stepless airflow control for precise adjustment.

Replacing coils
Pull the pod out of the device. Turn the pod upside down and pull the coil straight out. Align the flat edges of the new coil with the slot on the pod base and push firmly until seated flush. Refill and prime before vaping.

Battery indicator
LED models: green above 60%, blue between 30% and 60%, red below 30%. Screen models display battery percentage directly.

Caliburn G Series Troubleshooting

Device will not fire
Push the pod firmly in until it clicks. If you recently replaced the coil, confirm the flat alignment edges are correctly seated in the pod slot.

Spitting or gurgling
The coil is flooded. Remove the pod and flick it gently over a paper towel to clear excess liquid. Wipe contacts dry before reinserting.

Leaking
Use e-liquids with a 50/50 VG/PG ratio. High-PG thin liquids are more prone to leaking. Store the device upright when not in use.

Burnt taste
The coil needs replacing or was not primed correctly. If the coil is new, fill and wait 10 minutes before the first draw. If the coil has been in use for a while, replace it.

Coil life
Caliburn G coils typically last 1 to 2 weeks with regular use. Sweetened dessert and candy e-liquids shorten coil life significantly. Menthol, fruit, and tobacco blends are easier on coils.

Frequently Asked Questions

What is the difference between Caliburn G3 and G4?

The G4 adds a 1300mAh battery (vs 900mAh on the base G3), an animated OLED screen, PRO-FOCS 4.0 flavour technology, and 5–35W adjustable wattage with Storm and Wave modes. The G3 Pro offers stepless airflow and a full LCD screen that the G4 Kit does not have. For most vapers, the G4 Kit is the better all-round choice. The G3 Pro is worth considering if stepless airflow is a priority.

Why is Caliburn discontinued?

The original Caliburn (non-G) has been phased out in favour of the G series. Uwell continues to develop new G series models. The G3, G4, and G5 generations are all currently available in Canada as of 2026.

What is the best Caliburn device in Canada?

The Caliburn G4 Kit at $40.99 is the best all-round choice for most Canadian vapers in 2026. For battery life at the lowest price, the G5 Lite at $25.99 is the stronger value. For maximum control and the largest battery, the G4 Pro at $48.99 is the top G4 option.

Is Caliburn G4 better than G3?

For most vapers, yes. The G4 Kit has a larger battery, newer PRO-FOCS 4.0 flavour technology, and an animated OLED screen at a lower price than the G3 Pro. The G3 Pro is the exception if stepless airflow control is what you specifically need.

Why is G5 better than G4?

The G5 Lite packs a 1600mAh battery with 35W output and PRO-FOCS 4.0 technology at $25.99 less than the G4 Kit. If battery life is the priority and you do not need the animated screen or Storm/Wave modes, the G5 Lite delivers more battery capacity at a lower price.

What pods are compatible with Caliburn G series devices?

All Caliburn G series devices use the GPP pod platform. G3, G4, and G5 pods are cross-compatible across generations. The G5 introduced GPP Alpha Edition pods which also work in G4 and G3 devices.

How long do Caliburn G coils last?

Caliburn G coils typically last 1 to 2 weeks with regular use. Sweetened e-liquids reduce coil life. Priming a new coil by waiting 5 to 10 minutes after filling before vaping significantly extends coil life.
