URSA Nano 3 vs Lost Vape Thelema Nano

Vaping tech continues to evolve rapidly, and two of the most buzzed-about pod kits in 2025 are the URSA Nano 3 and the Lost Vape Thelema Nano. Both offer premium craftsmanship, cutting-edge features, and excellent flavor performance—but which one suits your vaping style best? In this comparison review, we’ll dive into their design, features, vaping experience, and finally, crown a winner based on use case.

Design & Build Quality

URSA Nano 3 exudes elegance with its fashion-inspired aesthetic, a slim body, and a shimmering RGB light bar that runs along the side. The zinc alloy construction feels premium in hand, and the compact dimensions (14 x 24 x 113.5mm) make it highly portable. Its RGB indicator is not just eye-candy but also serves a purpose by signaling battery levels intuitively.

On the flip side, the Thelema Nano leans into a more modern, gadget-style aesthetic with a vibrant 0.96-inch TFT color screen, textured PU or PC panels, and dopamine-themed color options. Despite its extra power and screen, it remains lightweight and pocketable. You also get both auto-draw and fire button activation, giving you flexibility in how you vape.

Verdict:
If you’re into subtle, fashion-forward devices, the URSA Nano 3 wins on elegance. But for tech-savvy vapers who love screens, buttons, and color, the Thelema Nano takes the edge.

Power & Performance

The URSA Nano 3 is powered by a 1200mAh battery with a maximum output of 30W, which is plenty for MTL and moderate RDL styles. It’s designed for longevity—up to 4 days of use per charge—with smart battery indicators and fast Type-C charging (5V/2A). It’s compatible with the URSA V2 cartridges, offering smooth airflow and strong flavor reproduction, especially with nic salts or lower-wattage freebase juices.

In contrast, the Thelema Nano pushes the boundaries of pod vaping with 45W max output, a 1500mAh battery, and Dual Mesh technology in the E Plus cartridges. The star of the show is its ECO & BOOST modes—ECO saves battery and coil life by firing only one mesh, while BOOST activates both coils for intense flavor and denser clouds. This makes it perfect for flavor chasers and vapers who prefer sub-ohm performance in a pod-sized format.

Verdict:
Thelema Nano clearly wins on raw power and versatility. However, if you want a more restrained, efficient experience with fewer buttons and menus, the URSA Nano 3 is ideal.

Flavor Delivery & Coil Technology

URSA Nano 3’s URSA Cartridge V2 has seen marked improvements from previous models, boasting 30mL+ lifespan, enhanced aroma retention, and consistent performance. The air-tight design delivers a sweeter, smoother vape that works well for MTL and tight RDL settings.

The Thelema Nano’s E-CORE TECH 3.0 and E Plus Dual Mesh Cartridge system is on another level—it boosts sweetness, complexity, and throat hit in ways that rival traditional box mods. Thanks to its sub-ohm capability, it excels with freebase e-liquids and offers a truly layered flavor experience.

Verdict:
Both provide excellent flavor, but for richer, deeper, and more customizable flavor, the Thelema Nano takes the crown. URSA Nano 3 stays strong in the MTL game but can’t quite compete with sub-ohm performance.
