If you’ve spent more than ten minutes looking at the Caliburn G4 lineup you’ve probably noticed that Uwell made three versions of essentially the same device and priced them within $26 of each other. The G4 Mini at $22.99, the G4 at $40.99, the G4 Pro at $48.99. Same Pro-FOCS 4.0 flavour technology, same GPP pod compatibility, same 35W output. So what are you actually paying for when you step up?
We stock all three at Robson Smoke Shop across our four Vancouver locations. Here’s what we’ve learned from selling them.
The Short Answer – IF You Don’t Want to Read The Whole Thing
Buy the G4 Mini if you want the simplest possible daily carry. No screen, no button, no decisions. Draw and vape.
Buy the G4 if you want to actually see what your device is doing and have two output modes to play with. The colour screen and Storm/Wave modes make a real difference.
Buy the G4 Pro if you want the full experience. Touchscreen, Custom Mode, biggest battery, most control. It’s $48.99 and worth every dollar over the G4 if you’re going to actually use the features.

The Caliburn G4 Mini – $22.99
The Mini strips everything back. No screen, no fire button, no output modes. You insert a GPP pod, inhale, and the device fires automatically between 5W and 35W depending on how hard you draw. That’s it.
What surprises people is how good the flavour is for a device with zero settings. Pro-FOCS 4.0 does the work the coil temperature and e-liquid saturation are optimised automatically. You’re not sacrificing flavour to get simplicity.
The 1100mAh battery is the smallest of the three but still gets moderate vapers through a full day. USB-C charges it in about 45 minutes. The dual airflow system is genuinely clever for a device at this price — flip the pod 180° for a tighter draw, use the side slider for fine adjustment. Two independent controls in a $22.99 device is unusual.
The Mini is the top seller in the G4 range at our Commercial Drive location. Most of the people buying it are either coming off disposables and want something reusable without complexity, or experienced vapers who want a backup device that requires zero thought.
Buy the G4 Mini if:
- You want the lowest price in the G4 range
- You don’t care about screens or output modes
- You’re an ex-smoker who wants cigarette-like simplicity
- You want a backup device that just works
Skip the Mini if:
- You want to see your wattage or battery level precisely
- You want Storm or Wave mode
- You’re a heavy vaper 1100mAh may not make it through your day
→ Buy the Caliburn G4 Mini – $22.99
The Caliburn G4 Kit – $40.99
The G4 is where the lineup gets interesting. You’re paying $18 more than the Mini and getting a 0.85″ colour screen, a fire button, Storm and Wave output modes, and a slightly larger 1300mAh battery. Same Pro-FOCS 4.0, same GPP pods.
Storm Mode delivers maximum power from the first millisecond punchy, immediate, dense. Wave Mode delivers a smoother, more progressive draw that builds through the puff. The difference between the two is noticeable. Most vapers end up using Wave for daily vaping and Storm when they want intensity on a fresh pod or a premium e-liquid.
The colour screen shows your wattage, battery level, and puff count. After using the Mini’s LED indicator it feels like a significant upgrade you actually know what your device is doing.
The fire button gives you the option of button firing on top of auto-draw. Some vapers prefer button-only for more controlled puffs. Others never touch it. Having the choice costs nothing once you have it.
At $40.99 the G4 is the sweet spot in the lineup for most vapers. Enough features to feel like a premium device, not so many that it becomes complicated.
Buy the G4 if:
- You want a colour screen without paying G4 Pro prices
- Storm and Wave modes appeal to you
- You want a fire button alongside draw activation
- $40.99 is your budget ceiling
Skip the G4 if:
- You genuinely don’t care about modes or screens save money with the Mini
- You want Custom Mode or a touchscreen step up to the Pro
→ Buy the Caliburn G4 Kit – $40.99
The Caliburn G4 Pro – $48.99
The G4 Pro is the first Caliburn ever built with a touchscreen. The 2.51″ display responds in 0.2 seconds and gives you one-tap control over every function wattage, output mode, UI theme, puff counter, device name, screen settings. No button sequences, no cycling through menus.
The feature that actually sets it apart from the G4 is Custom Mode. Storm and Wave are preset power curves. Custom Mode lets you set the output independently at the start, middle, and end of each puff you control the entire puff arc rather than just selecting a preset. Experienced vapers who’ve used box mods will recognise what this gives you. It’s a level of control that doesn’t exist on any other Caliburn.
The 1800mAh battery is meaningfully larger than the G4’s 1300mAh. Heavy vapers who struggled to get through a full day on the G4 or Mini will notice the difference.
The pod capacity is 2mL in the Canadian configuration smaller than the G4’s 3mL. That’s the one genuine trade-off on the Pro. You’ll refill more often. For most vapers it’s not a dealbreaker but it’s worth knowing.
Six UI themes three standard, three unlocked by hitting puff milestones. Small detail but it makes the device feel more personal than anything else in the G4 range.
Buy the G4 Pro if:
- You want the most advanced Caliburn ever made
- Custom Mode interests you it’s genuinely different from preset modes
- You want a touchscreen interface
- 1800mAh battery matters for your usage level
- You’re willing to pay $48.99 for the full experience
Skip the G4 Pro if:
- You’ll never use Custom Mode the G4 gives you Storm and Wave for $8 less
- The 2mL Canadian pod capacity bothers you vs the G4’s 3mL
→ Buy the Caliburn G4 Pro – $48.99
What About GPP Pods?
All three devices run on Caliburn GPP replacement pods – 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω. Whichever G4 device you buy, your pods are the same. If you’re upgrading from a G3, your existing G3 pods are also compatible with all three G4 devices.
The 0.6Ω pod is included in each kit and is the right starting point for most vapers – works with both nicotine salts and freebase, versatile draw, good flavour at any wattage setting.
The Honest Recommendation
If you’re buying your first Caliburn or upgrading from a disposable – start with the Mini. It’s $22.99 and delivers the same flavour technology as the $48.99 Pro. If you end up wanting more features you’ll know exactly which ones matter to you.
If you’ve used a Caliburn before and want an upgrade – go straight to the G4 Pro. The G4 is a good device but the Pro’s touchscreen and Custom Mode are genuinely different from anything Uwell has made before. The $8 difference over the G4 is worth it.
The G4 Kit sits in between and serves vapers who want colour screen and output modes without paying the Pro price. It’s a legitimate choice just know what you’re getting and what you’re not.
All three are in stock at Robson Smoke Shop across our four Vancouver locations. Order before 7PM for same-day delivery anywhere in Metro Vancouver by 10PM.
