If you're looking for the best refillable vape, the Uwell Caliburn G4 Vape Pod System deserves your attention. This slim, smart device improves flavour, boosts control, and simplifies vaping. It’s a strong choice for new users and experienced vapers alike.
Why the Uwell Caliburn G4 Stands Out
The Caliburn G4 doesn’t just perform—it lasts. With a large 1300mAh battery and up to 35W output, it powers through your day without constant recharging. You can pick your style with two vaping modes:
-
Storm Mode: Delivers a strong and steady vape
-
Wave Mode: Adds a gentle pulse for a smoother draw
These modes give you flexibility without overcomplicating things.
Better Flavour Starts Here
Uwell built the Caliburn G4 using upgraded PRO-FOCS 4.0 technology, which improves flavour by 35% and helps your pods last longer. That means fewer replacements and more satisfaction from every puff.
Want full control? The 0.85" colour screen shows battery, wattage, and puff count. You also get animations and custom display themes, which look neat—but let’s be honest, I was more interested in real performance.
My Experience with the Caliburn G4
I’ve used a lot of refillable vapes over the last three years, but this one surprised me. Right out of the box, I noticed a small shift in flavour from the G3 pods—but it was a welcome change. The G4 hits smoother, and I haven’t touched another device since making the switch.
The battery life? Incredible. It’s the best I’ve tried in years. This thing holds a charge like a champ, and when I’m out and about, I don’t even think about it. That alone makes it perfect for daily use.
Also—can we talk about the finish? Uwell dropped the matte shell from the G3 and gave the G4 a glossier look. I wasn’t sure about it at first, but now I love it. It doesn’t show dirt or fingerprints, so I’m not grossed out when I pull it from my bag. Clean, shiny, and reliable—big win.
Another huge plus: the pod compatibility. Uwell got it right by making the G4 work with both their new pods and the old G3 ones. It’s a small detail that saves a lot of hassle. No more wondering if I’m buying the wrong pods. Just pop it in and go.
No Leaks. No Stress.
Leakage is a deal-breaker. Uwell solves this with U² Tech, which uses ultrasonic welding and a smart U-shaped airflow path to stop leaks before they start. You also get a clear juice window, so you’ll always know how much E-Liquid is left.
Refill with Ease
The G4 gives you pod compatibility and flexibility. Use the 3mL Caliburn GPP pods for longer sessions, or switch to 2mL Caliburn G3 pods if you prefer smaller refills. Both use a side-fill design that keeps things neat.
