Uwell Caliburn G: Key Points You Need to Know

The Uwell Caliburn G represents a significant evolution in the pod system vape category. Since the original Caliburn launched in early 2019, it has remained the benchmark against which all refillable pod vapes are measured. The Caliburn G maintains the compact form factor users appreciate while introducing replaceable coils, transforming it from a traditional pod system into a pod AIO device.

What Makes the Uwell Caliburn G Different from the Original?

The Caliburn G introduces several key changes that distinguish it from its predecessor while maintaining the core appeal of the original design.

Product Overview and Specifications

The Caliburn G pod differs from its predecessor in several fundamental ways. While the original Caliburn used disposable pods, the G introduces a replaceable coil system with 0.8-ohm UN2 Meshed-H coils. The device pushes 18 watts compared to the original's 11 watts, delivering increased vapor production and warmth.

Available Colors and Pricing

The vape pod system comes in six color options to suit different preferences. Pricing varies by retailer and changes over time. Most kits on BEST VAPE are typically bundled with the Caliburn G device, a refillable Caliburn G pod (cartridge), two UN2 Meshed-H 0.8-ohm coils, a Type-C charging cable, and a user manual.

The transition to replaceable coils reduces long-term costs compared to purchasing entire pod replacements. This design choice makes the Uwell Caliburn G more economical for regular users while maintaining the convenience of a compact pod system.

How Is the Caliburn G Pod System Built and Designed?

Uwell refined the construction while preserving the portable form factor that made the original Caliburn successful.

Size and Form Factor Comparison

The Caliburn G maintains nearly identical dimensions to the original, measuring slightly wider and thicker. Users transitioning from the original Caliburn will barely notice the size difference. The device remains highly portable at 60 grams, fitting comfortably in pockets without adding bulk.

Design Features and Improvements

Uwell expanded the ridge pattern from the original's corners across the entire front and back panels of the G. This textured surface improves grip and adds visual interest. The firing button features a bronze accent and provides more tactile feedback compared to the somewhat mushy button on the original.

The branding has been refined with a semi-transparent "Caliburn" print above the LED indicator, replacing the more prominent white lettering of the original. The battery housing includes viewing windows for monitoring e-liquid levels, now slightly thicker for easier visibility.

Mouthpiece and Pod Connection

The redesigned mouthpiece is larger externally, though the airflow hole is considerably smaller. This change took some adjustment initially, but serves the device's MTL focus. The Caliburn G pod now uses a click-lock mechanism instead of magnets, providing A more secure attachment compared to the weak magnets in the original.

Overall Build Quality Assessment

The pod system vape demonstrates solid construction throughout. The combination of PCTG and aluminum alloy provides durability without excessive weight. All components fit together precisely, with no rattling or loose parts. The click-lock pods and improved button feel represent tangible quality improvements over the already well-built original.

How to Set Up Your Caliburn G Vape Pod System?

The setup process involves a few straightforward steps to prepare the device for optimal performance.

Coil Installation Steps

Setting up the Uwell Caliburn G requires a few additional steps compared to pre-filled systems.

● First, prime the coil by dripping 4-5 drops of e-liquid directly inside.

● Align the coil with the hole at the bottom of the pod—the flat side ensures proper orientation. The coil will only fit when correctly positioned.

E-Liquid Filling Method

● Remove the mouthpiece by pushing it sideways, which is easier with the pod installed in the battery.

● Fill the pod by inserting the bottle tip into the red filling gasket. The top-fill design matches the original's convenient system.

● Allow 5-10 minutes for the coil to saturate fully before use.

Device Operation Instructions

Press the fire button five times to power on the device. The Caliburn G offers dual firing modes: button-activated or draw-activated. Both methods perform similarly, though pressing the button slightly before inhaling produces a marginally warmer vape. The LED indicator lights up with each activation, displaying battery level through color coding.

Airflow Configuration Options

Pod orientation switches between two airflow options. While the brand may label them “MTL/RDL,” the test finds the real-world difference feels more like “tight MTL” versus “slightly looser MTL,” and switching is as simple as reinserting the pod in the opposite orientation.

How Does the Pod System Vape Perform?

The Caliburn G delivers performance improvements across multiple areas compared to the original model.

MTL Airflow Characteristics

In actual use, the overall draw leans MTL strongly: the tighter setting feels closer to a cigarette-like restricted pull, while the looser setting is a bit more open but still clearly MTL—better for users who want a smoother, less restrictive MTL draw without fully shifting into a true RDL style.

Flavor and Throat Hit Experience

Flavor production shows marked improvement over the original. The combination of the 0.8-ohm mesh coil and 18-watt output creates noticeably warmer vapor with enhanced taste. The tighter airflow contributes to improved throat hit, making 9 mg freebase nicotine satisfying. The device also performs well with 20 mg nicotine salts without requiring higher concentrations.

E-Liquid Compatibility and Wicking

The UN2 Meshed-H coils are commonly reported to handle 70 VG e-liquids without difficulty. Even during extended chain vaping sessions, the wicking typically keeps pace without producing dry hits. The pod is often reported to show no leaking issues at the contacts, maintaining clean performance throughout use.

Coil Longevity and Lifespan

Testing with three devices simultaneously, one unit processed nine complete 2 mL pods on a single coil. While the coil continued functioning after this point, performance began declining noticeably. Coil life varies based on e-liquid composition, with clearer liquids typically extending coil longevity. The results indicate satisfactory durability for typical use patterns in that test scenario, though results can vary by e-liquid sweetness and usage style.

Performance Strengths

The vape pod system excels in flavor delivery, vapor warmth, and throat hit. The dual MTL airflow options accommodate different preference levels within that vaping style.

What Is the Uwell Caliburn G Battery Life Like?

The battery system balances portability with practical runtime for daily use.

Battery Capacity and Endurance

The 690 mAh battery provides adequate runtime for a device this size, delivering approximately enough use to get through around 3 mL of e-liquid before needing a recharge (usage-dependent). This represents reduced capacity compared to the original Caliburn's two pods per charge, attributable to the increased up-to-18W output versus 11 watts.

USB Type-C Charging Specifications

The Type-C port at the device's bottom enables fast charging, completing a full charge in 45 minutes. The LED flashes slowly during charging and remains solid green when complete. Pass-through charging allows device use while plugged in, maintaining functionality during charging sessions.

LED Battery Indicator Guide

The LED provides clear battery status information through color coding:

● Green: 60-100% remaining

● Blue: 30-60% remaining

● Red: 0-30% remaining

The indicator activates with each button press or draw, keeping users informed of remaining battery capacity.

FAQ

Q1. Can the Caliburn G Use the Original Caliburn Pods?

No, the Caliburn G uses a different pod design with replaceable coils. The original Caliburn pods are not compatible with the G model. The new system uses UN2 Meshed-H coils that insert into the bottom of dedicated Caliburn G pods. This redesign provides cost savings over time since users replace only the coil rather than the entire pod. The pods themselves can often be cleaned and reused with fresh coils, depending on wear and condition.

Q2. Can You Adjust the Power/Wattage on the Caliburn G?

The Caliburn G doesn’t use a traditional wattage adjustment menu. It’s designed to keep operation simple by delivering direct output based on battery level and coil resistance, so your vape can feel a bit stronger on a fuller charge and slightly softer as the battery drops. If you want a warmer hit, many users prefer button-firing (pressing the fire button a split second before inhaling) versus draw-activation, and choosing the right e-liquid strength can also fine-tune satisfaction.

Q3. How Long Does Each Coil Last in the Caliburn G?

Coil longevity in the Uwell Caliburn G varies based on e-liquid type and usage patterns. One coil lasted through nine full 2 mL pods before performance noticeably declined. Clearer e-liquids with less sweetener typically extend coil life, while heavily sweetened liquids may reduce it. Users can expect several days to over a week of use per coil under normal vaping conditions.
