The vaping market continues to evolve, and manufacturers keep raising the bar with better technology, improved design, and longer battery life. Among the standout releases in the pod system category, the Uwell Caliburn G5 Koko Pod Kit has quickly earned attention. It combines portability, power, and flavor performance in a compact square design that feels both modern and practical.

In this detailed review, you will learn everything about the device, including its design, battery performance, output modes, pod compatibility, airflow system, and overall user experience. If you are considering a compact yet powerful pod system, this guide will help you decide.

Introduction to the Uwell Caliburn G5 Koko Pod Kit

Uwell has built a strong reputation in the vaping industry for producing reliable and flavor-focused devices. The Caliburn series, in particular, has gained a loyal following because it consistently delivers smooth performance and long-lasting coils.

The G5 Koko continues that legacy. However, it also introduces new upgrades that make it more versatile and powerful than many previous Koko-style models. It supports adjustable wattage, dual output modes, a large battery, and upgraded flavor technology. As a result, it appeals to both beginners and experienced users.

Design and Build Quality

Compact Yet Premium Feel

The first thing you notice about the G5 Koko is its compact square shape. The device follows the signature “Koko” style, which makes it easy to hold and carry. However, Uwell refines the overall look with a leather-textured finish that adds a premium touch.

The device feels solid in the hand. It does not feel cheap or fragile. Instead, it gives a confident grip while remaining lightweight. Because it weighs around 66 grams, you can carry it in your pocket all day without discomfort.

Practical Portability

Portability plays a major role in the success of any pod kit. The G5 Koko includes a lanyard hole, which allows you to wear it around your neck. Therefore, you can keep it accessible during daily activities without constantly reaching into your pocket.

In addition, the compact size makes it ideal for travel. It fits easily into small bags, purses, and even tight jeans pockets.

Battery Performance and Charging

1600mAh Battery Capacity

Battery life remains one of the most important features in any vaping device. The G5 Koko includes a powerful 1600mAh built-in battery. This capacity supports extended use throughout the day.

For moderate users, the battery can easily last a full day or more. For lighter users, it can last even longer. As a result, you spend less time worrying about charging and more time enjoying consistent performance.

Fast USB-C Charging

When the battery runs low, the device supports fast charging through a USB-C port. It supports 5V/2A charging, which significantly reduces downtime. Instead of waiting several hours, you can recharge the device quickly and return to vaping.

This feature becomes especially useful for busy users who need reliable performance without interruption.

Adjustable Wattage and Power Output

Up to 35W Output

The Uwell Caliburn G5 Koko delivers up to 35 watts of power. This output level gives you more flexibility compared to many basic pod systems that lock users into fixed power settings.

You can adjust the wattage in 1-watt increments. Therefore, you can fine-tune your vape according to your preference. Lower wattage provides a smoother and cooler vape, while higher wattage increases vapor production and warmth.

Ideal for MTL and RDL

Because of its adjustable output, the G5 Koko supports both mouth-to-lung (MTL) and restricted direct-lung (RDL) vaping styles. This versatility makes it suitable for users transitioning from smoking as well as experienced vapers who want a compact backup device.

Dual Output Modes: Waves and Storm

One of the standout features of the G5 Koko is its dual output mode system. Uwell introduces two distinct modes: Waves Mode and Storm Mode.

Waves Mode

Waves Mode focuses on smooth and consistent power delivery. It maintains a balanced output throughout each puff. As a result, you get stable flavor and a comfortable throat hit.

This mode works well for everyday vaping, especially if you prefer steady performance without aggressive heat.

Storm Mode

Storm Mode increases intensity. It ramps up power quickly at the start of each puff, creating a warmer and stronger experience. Because of this boost, vapor production becomes thicker and more pronounced.

If you enjoy bold flavor and a stronger throat hit, Storm Mode delivers that extra punch.

You can switch between modes easily, which allows you to adjust your experience depending on your mood or e-liquid choice.

Advanced Flavor Technology

Flavor quality often determines whether a pod kit succeeds or fails. Uwell integrates its PRO-FOCS flavor technology into the G5 Koko. This technology enhances flavor consistency and optimizes coil performance.

As a result, you experience a clear, rich, and smooth flavor with every puff. The device minimizes flavor drop-off over time, which means your e-liquid tastes fresh longer.

Whether you prefer fruit blends, dessert flavors, menthol, or tobacco profiles, the device maintains impressive clarity.

Pod Compatibility and Coil Options

GPP Pod Platform

The G5 Koko uses Uwell’s GPP pod platform. This system supports multiple resistance options, which increases flexibility.

Available resistance options include:

• 0.4Ω – Suitable for RDL vaping and higher wattage use

• 0.6Ω – Balanced performance between flavor and vapor

• 0.9Ω – Ideal for MTL vaping with smooth nicotine delivery

• 1.2Ω – Designed for tighter draws and higher nicotine strengths

Because of this range, you can customize your vaping style easily. You simply choose the pod that matches your preference.

Easy Refilling System

The pods feature a convenient side-fill system. You remove the silicone plug, fill your e-liquid, and seal it securely. The design reduces mess and simplifies maintenance.

In addition, the magnetic connection ensures that the pod sits firmly in place without wobbling.

Adjustable Airflow System

Airflow significantly impacts the vaping experience. The G5 Koko includes a top airflow design, which improves leak resistance and airflow efficiency.

You can adjust the airflow to control how tight or loose your draw feels. If you prefer a cigarette-like experience, you can restrict airflow. However, if you want more vapor, you can open it up for a looser inhale.

Because airflow adjustment works together with wattage control and coil selection, you gain full control over your setup.

Display and User Interface

Unlike many compact pod systems, the G5 Koko includes a clear display screen. The screen shows:

• Battery level

• Wattage setting

• Output mode

• Device status

This information helps you stay in control. You can quickly check your battery percentage and adjust power without guessing.

The interface remains simple and intuitive. Even beginners can navigate settings without confusion.

Ease of Use for Beginners

Although the device offers advanced features, it remains beginner-friendly. You can activate it using either draw activation or button firing. This flexibility makes it easy for new users to adapt.

The refill system is straightforward. The pod installation is simple. The display provides clear information. Therefore, beginners do not feel overwhelmed.

If you are switching from disposable devices or traditional cigarettes, the G5 Koko provides an easy transition while still offering room to grow.

Performance in Daily Use

In real-world usage, the Uwell Caliburn G5 Koko performs consistently. The battery lasts long. The coils maintain flavor. The device rarely leaks when used properly.

The compact design makes it ideal for commuting, social events, and travel. In addition, the adjustable settings allow you to adapt quickly to different e-liquids.

Because it balances power and portability, many users consider it an excellent daily driver.

Safety Features

Uwell includes multiple built-in safety protections, such as:

• Short-circuit protection

These features ensure safe operation. As a result, you can use the device confidently throughout the day.
