When it comes to refillable kits, few names stand out like Uwell. Their Caliburn and Crown series have shaped how MTL vaping is done; solid build, sharp flavour, and reliability across the board. For vapers in the UK looking for something that works without minimal setups, this is the brand you can actually count on.
But with so many Caliburns and newer names like Crown X out there, how do you choose? We’ve listed the most popular Uwell vape kits below. Each kit has its own strengths; some are better for beginners, others shine for advanced vapers.
Let’s get into the details.
What is Uwell: A Look at History & Growth
Uwell, a famous brand, entered the UK’s vape market in 2015. Its first major release, the Uwell Crown Sub-Ohm Tank, quickly gained attention worldwide for its stainless steel body and awesome flavours. Over the years, Uwell has built a product timeline defined by stable progression.
The shift to pod-based systems began with the original Caliburn in 2019. According to ECigIntelligence’s 2023 UK market survey, Uwell’s Caliburn range ranked among the most-used refillable pod kits across vapers. That’s for a reason. The kits didn’t leak. They didn’t burn out after a few days. And when most pods relied on plastic-tasting coils, Uwell’s Pro-FOCS flavour tech (Proportional Flavour Optimisation Core System) managed to deliver a clean draw over time without changing anything about the e-liquid itself.
Another point that sets Uwell apart is how they’ve handled compliance. Every refillable kit released post-2017 has met TPD standards for the UK and EU without sacrificing refill capacity or flavour. If you’re curious about what TPD is, check out our TPD Compliance Guide.

Frequently Asked Questions
How do I choose the right Uwell kit for my needs?
If you like a tight inhale that feels close to a cigarette, the Caliburn A3 or A2S works well. For more vapour and airflow, look at the Crown X or G3 Pro. Battery life is also key; some models last all day, others need topping up. Think about refill style too: snap-top fill (A-series) is quicker, while side-fill (G-series) gives more access. Beginners usually go for fixed-coil pods, while regular users prefer replaceable coils. Stick to what feels manageable, and avoid over-complicating it if you’re just starting out.
Can I use nicotine salts with Uwell kits?
Yes, most Uwell pod systems work well with nicotine salts, especially those with coil resistances above 0.8Ω. Kits like the Caliburn A2, A3, A2S, and AZ3 are built for this style of vaping. Nic salts absorb quickly into the bloodstream, so pairing them with lower-wattage Uwell kits gives a steady throat hit without burning the coil. Always check coil resistance before refilling.
Are Uwell pod systems better than traditional vape mods?
It depends on what you’re looking for. Uwell pod systems are better suited for those who prefer convenience and don’t want to deal with tanks, wattage settings, or coil building. Mods allow more control, but also require more effort. If you just want a clean MTL vape that fits in your pocket, kits like the Uwell Caliburn X or Crown X are better options. For experienced users who want high VG clouds, mods may still be the preferred ones.
What makes Uwell vape kits popular among vapers?
Uwell vape kits are popular because they’re consistent, easy to refill, and don’t break down quickly. Most models like the Caliburn G2 or A3 deliver reliable flavour without needing much adjustment. The pods snap in securely.
