The Uwell Caliburn ECO Family Explained: One Pod Platform, From G3 to G5

If you have ever hesitated to upgrade your pod vape because you did not want to throw out a drawer full of pods and start over, the Uwell Caliburn ECO family was built for you. From the Caliburn G3 generation through the latest Caliburn G5, every device in the range is designed around the same G-Pod Platform (GPP) cartridge system. In plain terms: the pods you already own keep working when you move up to a newer device. You can step up from a simple, pocket-friendly kit to a full-featured device with a screen and adjustable wattage without rebuying pods or hunting for a different coil.

This guide walks through the entire Caliburn ECO family, explains exactly which pods fit which devices, compares the current Caliburn G5 and G5 KOKO against the earlier Caliburn G4 and Caliburn G3 Pro KOKO, and lays out the full price ladder — starting at just $19.99. Everything here is in stock or regularly restocked at Futuristic Vapes, with same-day local delivery across Surrey, Delta and the wider Lower Mainland.

One platform, no pod anxiety: why "leveling up" a Caliburn costs you nothing extra

The single most useful thing to understand about this lineup is the G-Pod Platform. Uwell standardised the pod connection across the Caliburn G3, G4 and G5 families, which means the refillable cartridges are cross-compatible from one generation to the next. A pod that fits your Caliburn G3 will seat and fire in a Caliburn G4 or a Caliburn G5. Move up to the newest device and your existing pods come with you.

That has two practical benefits. First, it protects what you have already spent — your pods are not stranded the moment a new model arrives. Second, it lowers the cost and the hassle of upgrading, because the only thing you are actually replacing is the device body and battery, not the whole ecosystem around it. The newest GPP Alpha pod is the clearest example of this philosophy: it is engineered for an extended lifespan, and it drops straight into G3, G4 and G5 devices alike.

One honest caveat so you buy the right thing: this cross-compatibility applies to the G3-generation pods onward (the G3, GPP and GPP Alpha cartridges). The much older original Caliburn G and Caliburn G2 pods are a different, earlier design and are not part of this platform. If you are coming from a G or G2, you will move to the new pod family when you upgrade — but from G3 forward, you are set.

Meet the Caliburn ECO family

The ECO family spans three device generations. Within each generation you will usually find a standard model, a more compact or screen-equipped variant, and a KOKO version — the square, wearable, lanyard-friendly body style that Caliburn fans know well. Here is how the range breaks down.

The Caliburn G3 generation

The G3 generation established the platform and remains a popular, no-fuss entry point. It includes the Caliburn G3, the Caliburn GK3, the lightweight Caliburn G3 Lite, the screen-equipped Caliburn G3 Pro, and the Caliburn G3 Pro KOKO. The G3 Pro KOKO is worth singling out: it carries a 1250mAh battery, a 1.8-inch TFT colour display, draw-activated firing with adjustable wattage up to 35W, and stepless airflow for both MTL and restricted direct-lung draws — all in a compact square body.

The Caliburn G4 generation

The G4 generation pushed battery size and on-device features further. It includes the Caliburn G4, the compact Caliburn G4 Mini, the feature-rich Caliburn G4 Pro, and the Caliburn G4 Pro KOKO. The G4 Pro brought Uwell's first touchscreen to the Caliburn line along with an 1800mAh battery and adjustable output from 5W to 35W, while the G4 Pro KOKO carries one of the largest batteries in the entire family at 2000mAh. If raw battery capacity and on-screen control matter most to you, the G4 Pro pair is where the family peaks.

The Caliburn G5 generation

The current generation refines the formula and leans into the "more pods, less hassle" idea. It includes the Caliburn G5 Lite, the Caliburn G5 Lite KOKO, the full-featured Caliburn G5, and the Caliburn G5 KOKO. Every G5 model runs a 1600mAh battery with up to 35W output. The standard G5 adds a 0.85-inch HD colour screen and ships as a three-pod kit that includes the long-life GPP Alpha cartridge, while the G5 KOKO keeps things simple and stylish with its signature starlit display and draw-activated operation.

The pods: three cartridges, one family

Because the pods are the heart of this system, it is worth knowing exactly what is available and what fits. All three of the current cartridge types are sold individually at Futuristic Vapes and all work across the G3, G4 and G5 device families.

• G3 Replacement Pods (2mL) — available in 0.4Ω, 0.6Ω and 0.9Ω, these are the standard 2mL cartridges. The 0.9Ω is a tighter mouth-to-lung option, while the 0.4Ω suits a warmer, airier draw.
• GPP Replacement Pods (3mL) — available in 0.4Ω and 0.6Ω with a larger 3mL capacity, so you refill less often.
• GPP Alpha Pods (3mL, 0.6Ω) — the newest cartridge, built with Uwell's AlphaCore coil technology and rated for 17 or more refills (roughly a 50mL lifespan), which is considerably longer than a standard pod. This is the pod included with the full G5 kit.

All three work with both nicotine salt and freebase e-liquid, and all three seat across the G3, G4 and G5 devices thanks to the shared platform. If you are unsure which resistance to pick, a 0.6Ω is the most versatile all-rounder for most refillable e-liquids.

Spotlight: Caliburn G5 and G5 KOKO vs Caliburn G4 Pro and G3 Pro KOKO

A common question is whether the newest device is automatically the "best" one. Not necessarily — it depends on what you value. Here is a side-by-side of four representative models across the three generations, all of which share the same pod platform.

A few things stand out. The newest G5 is not the biggest-battery device in the family — that distinction belongs to the G4 Pro generation (1800mAh on the G4 Pro, and 2000mAh on the G4 Pro KOKO). What the standard G5 brings is the three-pod kit and the included long-life GPP Alpha cartridge, plus a clean HD interface. The G5 KOKO, by contrast, strips things back to a draw-activated, screen-free design in a compact wearable body at a lower price.

The G4 Pro remains the choice for anyone who wants the most hands-on control — a touchscreen and a true adjustable wattage range from 5W to 35W. The G3 Pro KOKO, meanwhile, shows how much capability the earlier generation already had: a full TFT display and adjustable output in a pocket-flat square. And because all four use the same pod platform, the decision is purely about the device features you want, not about which pods you will be locked into.

The price ladder: from $19.99 to full-feature

One of the reasons the Caliburn range stays popular is that it scales with your budget and your preferences, while keeping the same pods throughout. Here is roughly how the ladder looks at Futuristic Vapes:

• Bare-bones simple — Caliburn G5 Lite at $19.99: a 1600mAh battery rated for up to six days of typical use, dual adjustable airflow, and draw-activated simplicity. The most affordable way into the platform.
• A step up in style — Caliburn G5 Lite KOKO at $21.49: the same core performance in the wearable KOKO body, with vibration feedback and a breathing light.
• The everyday KOKO — Caliburn G5 KOKO at $29.99: compact, draw-activated, with the signature starlit display.
• The full G5 kit — Caliburn G5 at $49.99: three pods in the box (including the GPP Alpha), an HD screen and on-device controls.
• The full package — Caliburn G4 Pro and Caliburn G4 Pro KOKO: adjustable wattage, a touchscreen, and the largest batteries in the family (1800–2000mAh) for the longest time between charges.

Start simple if you are new, or go straight to the full-feature end if you want wattage control and the biggest battery. Either way, the pods you buy today carry over to whichever device you choose tomorrow. You can browse the whole entry-level range on the Simple Starter Kits page.

Why the Caliburn keeps selling

The original Caliburn arrived in 2019, and Uwell — a manufacturer founded in 2015 — has spent the years since refining the same core ideas across each generation. The Caliburn line has been one of our consistent best-sellers among customers who want a refillable device that is straightforward to use and known for its flavour delivery, thanks to Uwell's PRO-FOCS coil technology. The platform's track record of reliability over more than six years on the market is a big part of why people keep coming back to it, and why upgrading within the family feels low-risk: it is a known quantity.

Which Caliburn is right for you? A quick FAQ

Are Caliburn G3 pods compatible with the Caliburn G5?
Yes. The G3, GPP and GPP Alpha cartridges all share the G-Pod Platform and work across the G3, G4 and G5 device families. The original Caliburn G and G2 pods are an older, separate design and are not compatible.

What is the difference between the GPP pods and the GPP Alpha pod?
Both are 3mL cartridges that fit the same devices. The GPP Alpha uses Uwell's AlphaCore coil and is rated for a longer lifespan — 17 or more refills, roughly 50mL — compared with a standard pod.

Which has the biggest battery?
Within this comparison, the G4 Pro generation leads, with 1800mAh on the G4 Pro and 2000mAh on the G4 Pro KOKO. The G5 models use a 1600mAh battery.

What is the cheapest way into the family?
The Caliburn G5 Lite at $19.99 is the most affordable current entry point, and its pods carry over to any other device in the range.

Can I use both nicotine salt and freebase e-liquid?
Yes. All of the current Caliburn pods are compatible with both nicotine salt and freebase e-liquids.
