When customers ask us “G4 or G3 and Which one is actually better?”, we answer based on what we’ve seen people return, repurchase, or upgrade to — not just what’s written on the box.
We sell, use, and test pod systems every day — and the Caliburn G3 and Caliburn G4 are two devices we’ve personally handled, filled, charged, and vaped ourselves.
In this guide, I’ll share what I personally noticed, what we see in real usage, and which vape device we recommend depending on how you vape.
Our Quick Verdict :
From our experience, Should you Buy G4 or G3?
- We recommend Caliburn G4 to users who like modern look, vape daily and want stronger hits.
- We still recommend Caliburn G3 to beginners or users who want something functional, lightweight, simple, and reliable
* I’ve seen many G3 users come back later asking to upgrade — and in most cases, they move to the G4.
Side-by-Side Spec Comparison:
| Features | Caliburn G4 | Caliburn G3 |

| Max Power | 35W (noticeably stronger) | 25W (smooth) |
| Screen | 0.85” colour screen (clear & modern) | OLED (basic info) |
| Airflow | Pod-based airflow | Reversible pod airflow |

| What’s Vibe 😉 | Modern+ Stylish+ Functional | Basic + functional |
When I hand both devices to customers, most people immediately notice the stronger response on the G4.

Design & Daily Handling (What We Noticed)
Caliburn G3 – Our Experience
When I carry the G3:
- It’s extremely light
- It disappears in the pocket
- It’s perfect for quick nicotine satisfaction
We often recommend this to first-time pod users or ex-smokers who don’t want complexity.
Caliburn G4 – Our Experience
When we switched to the G4:
- Battery anxiety disappeared
- Vape looks stylish
- The screen made it easier to track usage
- Storm Mode felt noticeably punchier
From daily handling, G4 feels like a serious upgrade, not just a new model.
Battery Life: What We Actually See
From our own use:
- G3 usually needs charging by evening for heavy users
- G4 often goes into the next day without charging
I personally prefer G4 because I don’t need to think about charging during work hours.
Flavor & Hit Quality (Our Honest Opinion)
We test devices with:
- Salt nic
- Different pod resistances
- Long draw sessions
What we found:
G3: With Regular 20mg/ml flavor beast juice, regular 0.6 pod and multiple hits, Hit was perfect, smooth flavor, Clean and consistent smoke.
G4: With Regular 20mg/ml flavor beast juice, regular 0.6 pod and multiple hits, We got Fuller flavor, much stronger throat hit (especially Storm Mode)
If someone tells me “Flavor matters more than anything”, I recommend G4 without hesitation.
Ease of Use: Who Each Device Is Really For
Based on who buys what from us:
We recommend G3 if you:
- Are switching from cigarettes
- Want zero learning curve
- Prefer tight MTL
We recommend G4 if you:
- Already use pod systems
- Vape throughout the day
- Want control without complexity
This advice comes directly from customer behavior we observe, not theory.
Common Issues We’ve Seen (Honest Section)
We believe honesty builds trust.
G3 Issues We’ve Seen:
- Burnt taste if vaped multiple times
- Pods losing flavor sooner for heavy users
- Juice come to mouth sometime
G4 Issues We’ve Seen:
- Needs proper pod priming
- Some users don’t use modes correctly at first
None of these are deal-breakers — but we always explain them before selling.
Our Final Verdict:
After using both devices ourselves and helping customers choose every day:
Caliburn G4 is the better long-term device, while Caliburn G3 remains a great entry-level option.
