A Quick Intro to UWELL and FLUM
UWELL, a Shenzhen, China-based company, offers a large line of innovative vape products, from sleek and discreet pod systems to robust and stylish pod-mod vapes – all packed with new tech. With products marketed in over 80 countries, UWELL has quickly established itself as a leading global vape brand focused on innovation and optimizing user experience. Some of its popular products include the Caliburn series, the Crown series, and the Nunchaku series.
FLUM, based in Shenzhen, China, offers a range of disposable vapes in different flavors. These devices are perfect for both new vapers looking for an easy-to-use option and experienced users seeking a portable vape.
Brand History and Background of UWELL and FLUM
Let’s look at how the two brands evolved.
UWELL, established in 2015, became well-known in the vaping world after launching its Caliburn vape kits in 2019. These kits are designed to provide varied vaping experiences and feature advanced technologies like Pro-FOCS to improve the taste. The company has been recognized for its technological innovations and awarded with designations like "NATIONAL HIGH-TECH ENTERPRISE" and "SHENZHEN HI-TECH ENTERPRISE" in China. It received a warning from the US Food and Drug Administration (FDA) in 2010 against selling products with stealth pockets that can conceal e-cigarettes.
FLUM was founded by Flumigo Technology Ltd., a company based in China. It became popular after launching the FLUM Float series, the first disposables introduced by this vaping brand. As of 2024, FLUM hasn’t received FDA approval to sell their disposables in the USA. But, the products are widely available on various e-commerce platforms and specialized vape shops across the US.

Now let’s compare these brands in detail:
1. Design and Aesthetics
UWELL vapes are designed to have a minimalistic aesthetic. Most of UWELL’s products contain translucent shells that display LED lights when in use and side-mounted fillings for easy refills. To add a playful twist to their collection, their Valyrian range was created as a tribute to the hit TV series Game Of Thrones, with the design resembling the sigil of House Stark.
The FLUM Float and the Gio series are pen-style, cylindrical vape devices in a range of soft colors. In contrast, the Pebble, Pebble X, and Mello series feature rectangular-shaped gadgets with a smooth, matte-like exterior. The Mello lineup offers animated screens that allow easy monitoring of e-liquid capacity and battery life status.
2. Performance and Battery Life
The battery life of UWELL products varies depending on the specific model and usage patterns. For instance, the UWELL Caliburn GK3 features a 900mAh internal battery, with reviews indicating it can last through a day of moderate vaping. Conversely, the UWELL Crown X Pod Kit offers a 1500mAh battery capacity designed for long-lasting use that can potentially extend over a day for heavy vapers. Moreover, some UWELL devices, like Caliburn Tenet, feature a built-in rechargeable battery, while others, like Crown 5 Tank, require external batteries that can be replaced as needed.
The FLUM Float, Gio, and Mello devices, each with a 650 mAh battery, provide reasonably good longevity but might not satisfy heavy users. The Pebble devices, with a 500 mAh battery, fall short in endurance. However, the Pebble X devices come with a robust 2000 mAh battery, ensuring you enjoy extended vape sessions. Overall, some models excel and others require frequent recharging, making battery life a critical consideration for potential buyers.
3. Longevity
UWELL implements multiple quality control systems to ensure consistent product reliability. This is done per their commitment to providing long-lasting, high-performance vaporizers.
The FLUM Float and Gio devices, with up to 3000 puffs and 650 mAh batteries, are suitable for moderate users and might require frequent recharging. The Pebble and Pebble X devices, offering up to 6000 puffs, show better durability. Besides, the Pebble X's 2000 mAh battery provides extended use. The Mello lineup stands out with an impressive 20,000 puffs. However, its small 650 mAh battery may require more frequent charging than you’d like.
4. Flavor Selection and Nicotine Options
UWELL offers a diverse range of e-liquid flavors and products designed to enhance the vaping experience. Some of the flavors available for UWELL products include:
FLUM disposables are available in a variety of fruit-based, and other flavors, including:
5. Vaping Experience
UWELL vapes are highly regarded for their excellent flavor experience and vapor production. Several UWELL products boast the patented “Pro-FOCS Flavor Technology” - a feature that promises a pure and consistent vaping experience.
The Flum Mello devices are equipped with hybrid 2.0 mesh coils, which deliver consistent flavor from the first draw to the last. The adjustable airflow button allows for precise control over the air-to-e-liquid mix, providing a personalized vaping experience. You can also view essential information, such as remaining e-liquid and battery levels, on an HD display screen.
6. Health and Safety Concerns
The UWELL brand's official website and product pages are upfront about the addictive qualities of nicotine, making it clear that their offerings are strictly for adult users. It's important to note that nicotine use is widely associated with addiction, nausea, breathing difficulties, and cardiovascular issues.
FLUM products contain nicotine, which can pose health risks and lead to addiction. Additionally, nicotine vapes may contain vitamin E acetate, diacetyl, and other harmful chemicals.
7. Regulatory Compliance and Legal Issues
In 2020, The US Food and Drug Administration (FDA) issued a warning to UWELL regarding a few products, including the Caliburn, stating that they did not have proper marketing authorizations and were thus considered adulterated and misbranded. As a result, UWELL has faced regulatory actions and has had to address these violations to remain compliant with US laws. Since then, legal scrutiny has eased up, and UWELL continues to sell its products in line with legal regulations.
FLUM hasn’t yet received FDA approval to sell their disposable vapes in the USA. It’s likely due to stringent regulatory requirements and the comprehensive review process that the FDA mandates for all tobacco and vape products.
Note: Consumers must also verify adherence to the latest local laws prior to any purchase of devices from these brands.
8. Nicotine Content
UWELL’s disposable vapes pack a punch with 20-50mg nic salt vape juice in 4-20ml capacities, catering to those who prefer a stronger nicotine hit with the convenience of disposability. Their reusable pod vapes, holding 2-4ml, are best paired with 5mg to 20mg nic salt vape juice, offering a customizable nicotine delivery to suit your vaping style.
FLUM vapes offer varying nicotine strengths and pod capacities, with most models featuring a 5% nicotine concentration. Only the FLUM Float devices provide a 0% nicotine option. The pod capacities of FLUM disposables range from 6.1ml in the Float and Gio series to 15ml in the Mello series, ensuring prolonged use and consistent delivery.
9. Compatibility with Other Products
UWELL’s proprietary design limits its cross-compatibility with other pods. However, UWELL devices are compatible with third-party e-liquids. UWELL makes replacement pods that may be compatible with more than one UWELL product range.
FLUM vapes are designed as disposables, making them incompatible with third-party e-liquids and accessories. While this gives you a hassle-free experience, it limits customization options if you prefer to mix and match components.
10. Availability and Accessibility
UWELL's products are widely available in most vape store chains across the US and available online.
A number of third-party websites allow you to order FLUM products online. However, the availability and shipping of these products can be impacted by location-specific regulations and restrictions.
11. Cost vs. Quality
UWELL vapes offer a variety of high-quality options across different price points. For example, the UWELL Caliburn A3 and AK3 are priced at approximately $30 and $32, respectively. Other UWELL products, such as the Caliburn X, are more expensive due to additional features like an OLED screen and adjustable wattage. Across the board, UWELL maintains a reputation for producing reliable and well-designed e-cigarettes, making them a popular choice among vapers.
The FLUM Float and Gio devices, priced at $13.99 and $11.99 respectively, provide a good entry-level experience with 5% nicotine and a 6.1ml pod capacity. The Pebble and Pebble X devices, at $14.99 and $15.99, offer 10ml pods and up to 6000 puffs, justifying the slightly higher cost. The Mello device, priced at $15.99, stands out with its 15ml pod. It also has advanced features like an HD display and hybrid mesh coils, offering superior quality for its price.
