Top 10 Uwell Vape Kits: Which One Should You Buy?

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.

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.
